''' | The browser does excacly what you are telling him to do :)
However I think you don't like the overflow it has.
What happens is that your '#box' expands because of your border and padding. You can make these properties inset, so it does not expand your element. You can do this with 'box-sizing':
'''
#box {
width: 100%;
height: 100%;
border: 5px solid red;
padding: 15px;
/*margin: 20px;*/
box-sizing: border-box;
}
'''
However you can not do the same with the 'margin', because the element is pushing itself from the body: it does what it supposes to do.
You can make a workaround by doing the same thing as above:
'''
body
{
padding: 20px;
box-sizing: border-box;
}
'''
'#box'
## jsFiddle
To prevent the double padding space, you should only apply it on the body element (or html, but i prefer the body as that is your visual element in the end). | |

How to make a webview load properly on a WebView in Android?

29,038,250 | 1 | 29,043,491 | How would you go about having tags already being preselected in their selectbox at the time the page loads? Here's my code so far:
HTML:
'''
<select class="selectBox operatingSystems" multiple="multiple">
<option>Windows</option>
<option>OSX</option>
<option>Linux</option>
</select>
'''
JS:
'''
$(".operatingSystems").select2({tags: true, tokenSeparators: [',', ' ']});
'''
I'm basically trying to get it to look something like it does on the select2 documentation page where they have "orange" and "purple" preselected. From: <URL> <IMAGE> | You can select an existing option by setting the 'selected' property.
'''
<select class="selectBox operatingSystems" multiple="multiple">
<option>Windows</option>
<option selected="selected">OSX</option>
<option>Linux</option>

'''
Would pre-select the OSX option in the select box. This isn't specific to Select2, it's how you set a pre-selected option in general for select boxes (both single and multiple select).
You can do this using vanilla JavaScript by setting the 'selected' property on the element.
'''
theOption.selected = true;
'''
Or using jQuery's '.val' method for setting the value.
'''
$("select").val(["OSX"])

In order for Select2 and other plugins to pick up the change in value, you may need to trigger the 'change' event.

15,351,422 | 1 | 15,352,141 | This might explain my question a bit better:
I need one child div positioned on top of the other so that the last-child is only showing around the edges, but the two child divs need to scroll together and keep the background of the first-child div static. This mesa that the viewport would be the first-child, but the content of the first and second child would have to scroll within the container so they can scroll together., with the first-child being the viewport.

I have the following HTML structure:
'''
<div class="container">
<div class="text">
<div class="row">Row</div>
<div class="row">Row</div>
<div class="row">Row</div>
<div class="row">Row</div>
<div class="row">Row</div>
<div class="row">Row</div>
</div>
<div class="bars">
<div class="a"></div>
<div class="a"></div>
<div class="b"></div>
<div class="c"></div>
<div class="b"></div>
<div class="a"></div>
</div>
</div>
'''
The 'bars' extend to the width of the page, and the 'text' div is overlaid on top of them, with a margin around it. I position each 'bars' div so that they match up at the same horizontal level with the visually corresponding 'row'.
The 'text' div is positioned to be 'x' pixels from each side, so that there is a margin around it. This way, you can see the ends of the 'bars' below it.
The markup is easy, but I can't figure out the CSS for this...
'text' is positioned absolutely, so that it can extend to the bounds of the page with a margin. This is fine if the content inside it stays within the bounds, but it does not in this case.
: I set 'container' to 'overflow:scroll' because I need the 'bars' to scroll with the 'rows'. Since 'text' has a background image, and is positioned so that you can just see the ends of the 'rows' beneath it, it has to be 'position:absolute'. This doesn't work, however, when the content exceeds the bounds of 'text. I can't add the background image to'container'because it would cover the ends of the'bars'.
Does that make sense? No? Here's a jsFiddle: <URL>
Does it still not make sense? Here's a picture:
<IMAGE>
Any ideas? Ask me some questions so I can explain this better. | You don't need a lot of the css that's there -- for example the .container. If I understand correctly (and I'm not 100% sure I do) you'd like a image on the .text div which remains fixed while the rest of the page -- bars and text scroll.
You cannot put the image on the text div as it will scroll; rather, I suggest putting the image on each .row with a 'position: fixed' as well as using 'padding-bottom:20px' instead of the margin, so that there appears to be an image behind all of the rows and the effect is continuous. That will give you the effect I think you're after

7,669,754 | 1 | 7,669,784 | I'm trying to implement dynamic array in C using realloc(). My understanding is that realloc() preserves old contents of the memory block the old pointer points to, but my following testing code suggests otherwise:

int DARRAYSIZE=5;
typedef struct dynamicArray{
int size;

int init(DArray *DAP){ //initialise the DArray
DAP->items=(int *)malloc(sizeof(int)*DARRAYSIZE);
if(DAP->items){

}else{
printf("Malloc failed!

return 1;
}

with the unexpected 0's in the output.
Please kindly advise what I'm doing wrong here, thanks! | You forgot 'sizeof(int)' in your 'realloc()', so you keep shrinking your array.
You also need to keep track of the number of items in use and the amount of space allocated in the dynamic array structure; these are two separate measures, and both are needed. But you can't use a global variable (currently DYNARRAYSIZE) to hold the size of every dynamic array. You need one per dynamic array.
'full()'

21,212,812 | 1 | 21,212,925 | I'm making a Java game. I have a Board class which extends JPanel, and have painted a node 'jim', which is an object instance of Ball class, to the screen using the 'paintComponent(Graphics g) {'. I can move the Ball object around on the JPanel using arrow keys.
Instead of representing the Ball object as a red square, I would like to have an image loaded.
Board class extends JPanel:
'jim = new Ball(0, 0, 50, 50, "jim");'
Ball class:
'''
public class Ball extends Component {
int x, y, w, h;
BufferedImage jimImg;
public Ball(int xLoc, int yLoc, int width, int height, String imgtype) throws IOException {
x = xLoc;
y = yLoc;
w = width;
h = height;
jimImg = ImageIO.read(new File("resources/Jim.png"));
loadImages(imgtype);
}
public void paint(Graphics g) {
g.drawImage(jimImg, 200, 0, null);
}
'''
It's not drawing on top of the red square though, or even appearing at all.
<IMAGE>
I have also tried appending the image as a JLabel... here's code within the Ball class:
'''
public void loadImages(String imgType) throws IOException {
if (imgType == "jim") {
JLabel utc = new JLabel("test");
ImageIcon utcImg = new ImageIcon("resources/Miller.png");
utc.setIcon(utcImg);
}
}
'''
But since 'Ball' class is not a JPanel, I can't add the label to the object. | 1. Don't compare Strings with ==, use equals if (imgType == "jim") ==>> if ("jim".eqauls(imgType))
2. You should be reading from a URL and not a File object. A URL can be obtained by using getClass().getResource(). e.g. jimImg = ImageIO.read(
Ball.class.getResource("/resources/Jim.png"));
3. You should use a try/catch in the constructor, so you won't have to later when you instantiate the Ball
4. It's preffered to paint on JPanel and override its paintCompoent, or JComponet
5. You never actually use the variable taken from your constructor to use to paint' g.drawImage(jimImg, x, y, w, h, this);
6. When working with painting, you should override the getPreferredSize of the JPanel so the frame will size it accordingly.

## EDIT
in response to OP commment
> "the way my classes are structured: Main class adds JFrame, where I add a new Board class object to the JFrame (Board class extends JPanel). Then I have Board class extends JPanel, which adds a new Ball object and has keyboard methods, etc... so I can move the Ball around. Then Ball Class is just a node with get/set methods getX(), setX() etc. So I can't add an image to the Ball class without extending JPanel?"
It doesn't look like you need ball to be a Component at all. Instead of making the ball a compoent, just make it a regular class. And in the paintComponent of your Board JPanel, just call ball.paint() for each ball you have.

And in the "Sheet3" sheet there is a big table (1000 columns) of data that I want to make a drop-down list from, from each column in it.
Now what I want is to drag copy this cell down so that the criteria will be like this:
1. =Sheet3!A1:A
2. =Sheet3!B1:B
3. =Sheet3!C1:C
4. =Sheet3!D1:D
5. ...etc
and so forth for 1000 rows, but when I do this, it does not increment the column letter, it's just like the first cell criteria value (=Sheet3!A1:A) for all other rows.
Is there a way to make this work without me having to edit each row in this 1000-row column manually?

<IMAGE> | You can fix this by defining exact border style for both table as well as td tags, by doing this you prevent browser from applying its own styling. Remove 'border='1'' and define
'''
table {
border: 1px solid #3C2610;
}
td {
border: 1px solid #3C2610;
}
'''
The cell dosn't exist in some IE's unless it's filled with something. If you can put a ' ' (non breaking space) to fill the void, that will usually work.
Apparently, IE8 shows the cells by default, and you have to hide it with empty-cells:hide But it doesn't work at all in IE7 (which hides by default)
Another solution is adding these two attributes to the table element: 'frame="box"' and 'rules="all"' like this:
'''
<table border="1" cellspacing="0" frame="box" rules="all">

20,934,801 | 1 | 20,934,889 | I'm building a users system plugin for a framework but the way I've currently set it up does not satisfy me. When the 'remember me' box is checked I create a cookie
'''
setcookie('rmb', md5('salt'.$id), ...);
'''
There are a few things I don't like about this. When I recreate a session from this cookie I do the following
'''
$db->prepare('SELECT id FROM users WHERE md5(CONCAT("salt",id)) = ?')
->execute([$_COOKIE['rmb']])
->fetch();
'''
Which seems alright but if I explain the query this is what I get
<IMAGE>
Highly inefficient, may run for hours, potentially. Apart from hashing with md5 being extremely insecure this system really doesn't seem reliable. Could you guys give me some pointers on how I can identify a user from a remember-me cookie hash efficiently and securely? | I think you can just create a 'challenge' that the client should send as a cookie in subsequent requests. When the user logs in:
'''
setcookie('username', put_username_here, ...);
setcookie('challenge', long_random_char_sequence, ...);
// UPDATE users SET challenge = ... WHERE username = ...
'''
When the user connects again something like:
'''
// SELECT ... FROM users WHERE username = $_COOKIE['username'] AND challenge = $_COOKIE['challenge']
'''
This won't compile, there is no input sanitization, etc... It's just the workflow you may try to implement.

Your floats are making your parent have a height of 0, which will in turn not allow you to have your borders. This fixes both those issues.

<li><a href="arbete.html">HEM</a></li>

</div>
.container{
width:100%;
height:50px;
border-bottom:1px solid black;

<URL>
You can also make your '<ul>' absolute and relative to your container and by using bottom:0; you'll have it stick to the bottom like so:
'''
ul {
list-style:none;
padding:0;
position:absolute;
bottom:5px;
right:0;
}
.container{
width:100%;
height:100px;
position:relative;

If you'll use this last technique please be sure to remove your '<ul>' margin-top, and just add that margin value to your container's height

thanks for your advices and answers | My suggestion for general ease of solving your problem: use a JPanel. Until you show good reason for not using this as the basis for your class, it remains in my mind the best solution for your problem. Otherwise, you'll need some code like:
'''
JComponent bordede = new JComponent() {
private static final long serialVersionUID = 2222L;
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
int width = getWidth();
int height = getHeight();
g.setColor(getBackground());
g.fillRect(0, 0, width, height);
}
};

I just added '"env": {"PYTHONIOENCODING": "UTF-8"}' in the 'sublime-build file'.
Done. Thanks everyone ;-) | > I'm getting an UnicodeEncodeError (that's why I was encoding in 'utf-8') ! I should mention I'm running my code within SublimeText. It's seems to be my problem. Any solution ?
don't encode manually, print unicode strings instead.
### For Unix
Set 'PYTHONIOENCODING=utf-8' if the output is redirected or if locale (LANGUAGE, LC_ALL, LC_CTYPE, LANG) is not configured (it defaults to C (ascii)).
### For Windows
If the content can be represented using the console codepage then set 'PYTHONIOENCODING=your_console_cp' envvar e.g., 'PYTHONIOENCODING=cp1252' (set it to cp1252 only if it is indeed the encoding that your console uses, run 'chcp' to check). Or use whatever encoding SublimeText can show correctly if it doesn't open a console window to run Python scripts.
Unless the output is redirected; you don't need to set 'PYTHONIOENCODING' envvar if you run your script from the command-line directly.
Otherwise (to support characters that can't be represented in the console encoding), install <URL> and either run your script using 'python3 -mrun your_script.py' or put at the top of your script:
'''
import win_unicode_console
win_unicode_console.enable()
'''
It uses Win32 API such as 'WriteConsoleW()' to print to the console. You still need to configure correct fonts to see arbitrary Unicode text in the console. | |

Second would be using base64 with the <URL>:

echo '<img src="data:image/png;base64,'.base64_encode($combined).'">';

I would recommend the first method, simply because it looks like a product display, the images are most likely public and hotlinking can be busted if you choose.
In both examples, since the image is inline, you wouldn't need to set the content-type to an image.
You should also place the correct mime type within the second version, either 'image/png', 'image/jpeg' or others depending on the image.

'$combined' contains the image, so you want to save this, simple use:

here 'Starters' and 'Main Course' are the titles of tabs. The easiest way to send this strings to bounded activities is to send them throught intents which are bounded to corresponding

And here is how you can get this string in 'BLD_IndividualListOfItems_Starters' activity :
'''
protected void onCreate(Bundle savedInstanceState) {
...
String title=getIntent().getExtras().getString("key_title");
}
'''
But as Raghunandan says, it's better to use fragments instead of depracated 'TabActivity'.
EDITED:
if you want to send text to corresponding activity dinamically, i mean exactly after tab is changed - you can:
1. create and broadcast custom intent with your string. (CUSTOM_INTENT_EXAMPLE)
2. in BLD_IndividualListOfItems_Starters activity register BroadcastReciever which will catch your custom intent and take text from it. (BROADCAST_RECIEVER_FROM_ACTIVITY_EXAMPLE)
You can't directly access tab text from 'BLD_IndividualListOfItems_Starters', because 'TabActivity' and 'BLD_IndividualListOfItems_Starters' are two different activities.
But you can send data between activities via bundles, static fields, singletons etc. Here is link to docs

6,489,182 | 1 | 6,489,270 | I am developing an IPhone cocos2d app with a scene like the the one depicted in the following image (I hope you can see that):
<IMAGE>
On the right there is a vertically scrollable menu contained in a separated layer (menulayer) which is itself contained in the main scene's layer. On the left there is a back button contained in the main scene's layer.
I am trying to exploit the UIScrollView as described in <URL>. However, despite I can see the UIScrollView working I am experimenting some problems:
1) while the menulayer actually scrolls it seems the menu does not. In fact when a press the menu item 8 the menu item 4 is selected, when I press the menu item 7 the menu item 3 is selected and so on.
2) the back button only works when the menulayer is at its first position
Do you have any idea of how shall I do to fix it? | You need to check you selectors. calls selectors from proper controls. check it carefully.Your problem shows your menu item 8 th selector bind with 4th same for others. some mis binding of selectors is present in your code so check them properly. | |

''' | The white space is appearing because it is there in your HTML code.
The closing '</li>' tag is on a new line. Carriage returns are counted as white space in HTML, and therefore you have white space at the end of the list item element.
The reason it is showing up is because you're using 'display:inline'. When usign 'inline' (or 'inline-block'), white space is relevant because 'inline' means "treat this element as plain text", and therefore any white space is considered an intentional part of the text.
The best way to get rid of this is to simply put the '</li>' closing tag on the same line as the rest of the text, so that there is no white space there.
There are a number of other ways around it, but most of them involve quite hacky CSS; simply closing up the space is by far the easiest option.
The next best alternative is to switch to using 'float:left' instead of 'display:inline'. This will also deal with the problem, but will change the way the whole thing is rendered, which will require you to make various other changes to your CSS to compensate. | |
9,122,640 | 1 | 9,123,413 | Here is the problem I'm trying to solve for my game.
I have this scenario:
<IMAGE>
I'm trying to solve for the position and size of the green rectangle. The circle is at 50%, 40% of the screen and its radius is proportional to the height of the screen.
The green rectangle must always be 10 pixels away from the bottom. Its left corner must be 10 pixels away also. And as can be seen in the image, the distance from the top right corner until the rectangle touches the circle is 10 pixels also.
Another constraint is that the green rectangle must always be 3 times wider than its height (aspect ratio).
Given these constraints, how can I solve for the position and size of the green rectangle?
Essentially, the Game Window can have a bunch of different aspect ratios so the green rectangle must look good in any of these situations.
I'm not necessarily looking for code but just an idea on how this could be solved.
Thanks | The thing to do in these situations is to describe the constraints mathematically, and see if it simplifies. This is an essential skill for geometric processing.
Let's assume the bottom left corner of the image area is (0,0). That puts the bottom-left corner of the rectangle at (10,10); we'll call the top-right corner (x1,y1). I'll assume you've already calculated where the circle will be since that's pretty straight-forward, we'll call the center (x2,y2) and the radius r.
The first constraint: the rectangle is 3 times wider than it is tall.
'''
x1-10 = 3 * (y1-10) or x1 = 3 * (y1-10) + 10 or x1 = 3*y1 - 20
'''
The second constraint: x1,y1 lies 10 pixels away from the circle. If we describe another circle 10 pixels larger than the first, the point will lie on it.
'''
(x1-x2)^2 + (y1-y2)^2 = (r+10)^2
'''
Substituting for x1:
'''
(3*y1 - 20 - x2)^2 + (y1-y2)^2 = (r+10)^2
'''
This is great, because r, x2, and y2 are known; the only unknown left is y1. Let's see if we can gather all the y1's together.
'''
(3*y1 + (-20 - x2))^2 + (y1-y2)^2 = (r+10)^2
3^2*y1^2 + 2*(3*y1*(-20-x2) + (-20-x2)^2 + y1^2 + 2*y1*-y2 + y2^2 = (r+10)^2
3^2*y1^2 + y1^2 + 6*(-20-x2)*y1 + 2*-y2*y1 + y2^2 = (r+10)^2
(3^2+1)*y1^2 + (-120 - 6*x2 - 2*y2)*y1 + y2^2 = (r+10)^2
'''
At this point it's looking almost like a quadratic equation. One more little tweak:
'''
10 * y1^2 + (-120 - 6*x2 - 2*y2) * y1 + (y2^2 - (r+10)^2) = 0
'''
The final step is to apply the <URL>.
'''
a*y1^2 + b*y1 + c = 0
a = 10
b = (-120 - 6*x2 - 2*y2)
c = (y2^2 - (r+10)^2)
y1 = (-b +/- sqrt(b^2 - 4*a*c)) / 2*a
'''
There are two possible answers from the quadratic equation, but one of them will put the rectangle on the far side of the circle. It should be easy to eliminate that case. | |
9,809,934 | 1 | 9,810,073 | The problem in my case is I can dynamically add / remove input boxes, but the problem is when I manually add a set of input box and remove button instead of press add button to create one, it can not remove it.
Is it possible to have 3 sets of input boxes but 2 remove buttons?
Thank you for any kind of help.

If you press cancel, the unhandled exception is allowed to continue until eventually the application is terminated. This allows the 'finally' block to execute.

Alternatively, if you handle the exception in a higher method you will definitely see the 'finally' block. For example:

29,350,867 | 1 | 29,487,343 | I'm working on MATLAB on some regions inside an image. I'm at a point in which I would like to be able to separate regions which exhibit some kind of regularity (e.g., being circle-ish or square-ish) from regions which does not resemble any known figure and which for my application are mere noise. I'll illustrate this using a descriptive MS Paint image:
<IMAGE>
Is there any tool that, (or even less, I know this can't be 100/100) will recognize the red thing as being ?
I'll deal with many shapes in a single image, so I don't mind if I carry on some red monsters along the way, as long as the majority of them is kicked out. Of course I know the indices of these regions, so I can manipulate them in MATLAB.
Many algorithms come to mind, e.g., getting the boundary and checking for its regularity/the number of times it changes curvature/..., checking for variations in vertical length through different columns (nearly 0 for the linear feature, really high for the red stuff), ...
However I was hoping in some help from a tool out there. It doesn't matter if this tool won't cover all cases (for example, will kick out circles), I've been very broad to get the maximum number of inputs from you guys - any tool will be inspiring and helpful (and, however, we can't expect a perfect answer for the deeper question - recognizing regular shapes - which seems more like a AI field of research). I also think that, while being broad, this is totally non-subjective so should fit in SO. Thank you.
: I'll deal mostly with elongated, extended features like the top-right one, so circles are not that relevant.
: To be 100% clear, I would need something (be it an already existant tool, or some ideas pointed out by you) that acts on the indices of the shapes, in terms of rows-columns into the original image, or on the boundary of the shape itself.
: Apart from tools/suggestions/ideas, you are welcomed to write down some lines of code ;) I'm getting the regions as from 'bwconncomp'. | I went for the easier road as suggested by @Mikhail in comments.
I found out 'regionprops' has a really helpful tool called <URL>. Quoting docs,
> Returns a scalar specifying the proportion of the pixels in the that are also in the region. Computed as Area/ConvexArea.
Convex hull is defined as the smallest convex polygon that can contain the region. So 'Solidity' goes up to 1 if the shape is kind of regular and has no convexity changes; down to 0 for my red shape, which leaves space between itself and the convex polygon.
Of course it never reaches 0, lowest value should belong to a kind of '+'-shaped sign. | |

35,185,083 | 1 | 35,196,764 | I am developing a component for Communique 5 (CQ5, now AEM) using JSP, HTML and JavaScript; and I found some trouble when trying to create two dropdowns for which the values of the second one will depend on the values on the first one.
In the component dialog (dialog.xml) I have two 'select' similar to these ones (simplified for clarity):
'''
...
<type
jcr:primaryType="cq:Widget"
defaultValue="Dark"
fieldLabel="Color Type"
name="./type"
type="select"
xtype="selection">
<options jcr:primaryType="cq:WidgetCollection">
<o1
jcr:primaryType="nt:unstructured"
text="Dark"
value="dark"/>
<o2
jcr:primaryType="nt:unstructured"
text="Light"
value="light"/>
</options>
</tipo>
<color
jcr:primaryType="cq:Widget"
defaultValue="dark-blue"
fieldLabel="Color"
name="./color"
type="select"
xtype="selection">
<options jcr:primaryType="cq:WidgetCollection">
<o1
jcr:primaryType="nt:unstructured"
text="Dark Blue"
value="dark-blue"/>
<o2
jcr:primaryType="nt:unstructured"
text="Light Blue"
value="light-blue"/>
<o3
jcr:primaryType="nt:unstructured"
text="Dark Green"
value="dark-green"/>
<o4
jcr:primaryType="nt:unstructured"
text="Light Green"
value="light-green"/>
<o5
jcr:primaryType="nt:unstructured"
text="Dark Red"
value="dark-red"/>
</options>
</color>
...
'''
That generates two dropdowns in the dialog:
- -
Something like this image:
<IMAGE>
How can I make the values of the second dropdown (colors) "update" depending on the value of the first dropdown (color type)? For example, if the color type is "dark" I only want to see dark colors: dark blue, dark green, dark red; and similarly, if the color type is "light" I want to see only light colors: light blue and light green.
I initially thought about doing this with JavaScript, adding a 'selectionChanged' listener to the first dropdown that would show/hide the options in the second list. But I couldn't find any relation between the field and the 'div' with the options (the generated code is not an HTML 'select' but a separate CQ5 structure with 'div's and hidden inputs).
Then I thought about having different dropdown lists for the second option: one with light colors and the other with dark colors, and directly show/hide the whole dropdown list instead of some options. Something that I could do by assigning 'id'/'cls' to the selection widget, but it complicates the logic behind and it is difficult to maintain (if I add new options, I'd need to create new dropdowns, and in my real code I have more than 2 options but 6).
How can I create to dropdowns in which the options in the second one depend on the option selected in the first one?
<URL> | You can try something like:
- - instead of nodes-options use optionsProvider for you component with colors:'''
function(path, record) {
return [{
text:"Dark Blue",
value:"dark-blue"
},{
text:"Light Blue",
value:"light-blue"
},{
text:"Dark Green",
value:"dark-green"
},{
text:"Light Green",
value:"light-green"
},{
text:"Dark Red",
value:"dark-red"
}];
}
'''
- then for your "color type" widget you can filter that options regarding type. Callback for event 'selectionChanged' can look like:'''
function(comp,value,checked){
var colorsDropDown = CQ.Ext.getCmp("colorsComp");
if (!colorsDropDown.original) {
colorsDropDown.original = colorsDropDown.optionsProvider;
}
colorsDropDown.optionsProvider = function(path, record) {
return colorsDropDown.original().filter(function (el) {
return el.value.indexOf(value) != -1;
});
}
colorsDropDown.setOptions(colorsDropDown.optionsProvider());
}
'''
There we get our "colors" widget by id, we set, then we save our original provider, set new, with filtering and also update available options.
It's somewhat dirty solution, but I hope, that it will give you some insight.
you also need to do similar manipulation on component initialization, to show correctly filtered options when widget first shown. | |
23,686,405 | 1 | 23,687,749 | I'm trying to mock a backend for an app that I'm building using Angular JS.

I would expect to see the 'PrograssBar' directly in the hierarchy of the activity root, but instead there's an additional FrameLayout that I have no idea where it comes from.
Here's a screen shot, painted the extra frame in YELLOW:
<IMAGE>
Thanks! | It seems like you are using the support v4 library and you forgot to put and id to your fragment xml tag :), so:
>
It comes from <URL> where you can see this:
'''
f.mView = NoSaveStateFrameLayout.wrap(f.mView);
'''
The reason for this is backwards compatibility and it is better explained in the comment header of 'NoSaveStateFrameLayout' which says:
'''
/**
* Pre-Honeycomb versions of the platform don't have {@link View#setSaveFromParentEnabled(boolean)},
* so instead we insert this between the view and its parent.
*/
'''
>
Well, I can think of three options:
1. You could have your very own implementation of FragmentManager say based on support v4 library version in which you omit this container, but I think the effort of writing/maintaining that code is not worth, plus I don't think the overhead due those FrameLayouts is gigantic, if you are having performance issues you probably have other View optimizations to perform besides this (say write a custom view -which extends View-) or say rethink your layout/fragments to reduce the amount of views in the hierarchy at certain point.
2. Wait for a new release of support v4 library which accomplishes 1. <- yup I'm a lazy person :D, you'll have to file a bug if there is not one already (see 3.), the cool part of this is you could even contribute your patch or someone else as well.
3. Support only platforms (or wait until) where the support v4 library is not (longer) needed, in API level 11+ FragmentManager implementation does not have this nested ViewGroup (see line 861 of 11+ FragmentManager), on those you get something like this:
<IMAGE>
I wouldn't worry much for those as I mentioned there are other optimizations you can invest that time in ;) | |

23,559,185 | 1 | 23,579,455 | I have a table in sqlserver with 55k geometry points. Each point are 5 meters apart and have a value assigned to them. My task is to draw these points in a google map.
Early I concluded that google maps could not handle drawing the 55k points. So I figured I had to group the points by value (10% intervals, 1-9,10-19 etc) to form polygons. However the polygons still consist of the same amount of points. I need to reduce the number of points in each polygon.
I need the polygons to atleast roughly keep their shape, so convex hull is out of the question.
Getting the concave hull/alpha shape would be the best solution I guess, but I haven't been able to find an implementation of it for sqlserver 2008 r2 or a .NET assembly / function.
It would also be acceptablef or me to just get the points that creates the outer line of the polygon, so I can pass those points to Google Maps and make it draw the polygons.
Here is a picture of how the collection of points for a polygon looks:
<IMAGE> | "Each point are 5 meters apart and have a value assigned to them."
That sounds a lot like you can treat the point set as a sparse 2D (boolean) matrix. You can use this to remove redundant points in the center of the shape. This could be applied to alpha shapes as well, but it only works well when the points are tightly packed together as in the case in your example and as implied by the above line in your question.
The pseudocode (not sure how to actually implement it in the languages you seek) for a single pass looks like this:
'''
Verify that the points are lexicographically sorted
Create a list to hold the unfiltered points
Create a set of the points for the fast membership tested needed
For each point:
If none of patterns are present:
Add the point to the list of unfiltered points
return list of unfiltered points
'''
The patterns are based on a 3x3 matrix, which represents the offsets from the center. So the center is (00,00), since it is not offset from the points. There are 12 main patterns to look for in the 3x3. Which can then be generalized into larger odd sized square matrices (5x5, 7x7, 9x9, 13x13...). The 3x3 with the offsets looks like this:
'''
[[(-5,+5),(00,+5),(+5,+5)],
[(-5,00),(00,00),(+5,00)],
[(-5,-5),(00,-5),(+5,-5)]]
'''
The 5x5 with offsets looks like this:
'''
[[(-10,+10),(-05,+10),(00,+10),(+05,+10),(+10,+10)],
[(-10,+05),(-05,+05),(00,+05),(+05,+05),(+10,+05)],
[(-10,000),(-05,000),(00,000),(+05,000),(+10,000)],
[(-10,-05),(-05,-05),(00,-05),(+05,-05),(+10,-05)],
[(-10,-10),(-05,-10),(00,-10),(+05,-10),(+10,-10)]]
'''
Just using one of the 12 patterns below will remove a lot of points leaving just the outer and inner (if the polygon isn't filled in) hull. The additional patterns are used to reduce the number of points in the outer/inner hull. This may be enough for your purposes. However, each additional pass should only remove about half the remaining points, but the number of patterns to look for grows at a rate of O(p^2). Note that p is O(d) where d is the greatest distance between two points in the point set, which in this special case is O(N). This should be enough to allow for a simple graph algorithm to extract the outer concave hull by picking an element on the convex hull and walking around the shape to produce the concave hull. Further passes will further reduce the number of points until some point dependent on which patterns are used. In the extreme case, it'll reduce it to a triangle.
There are then 12 patterns to look for to determine if the center point is redundant. This is done by checking if the center point is on a line (for the first four) or an approximate line/arc (last 8). Note that only one of these are needed to actually hollow out the point set. The rest are simply used to further reduce the number of points.
'''

[0,1,0]] | [0,1,0]] | [0,0,0]] | [1,0,0]]
'''
The patterns are intended to form arcs with the center point as the point under consideration. The above arcs are really more for example. To make things easier, only two more general patterns are used they are listed below. Note that at least one 2 must be present at at least one 3 must be present. If this is done until
'''
13. [[2,2,2], | 14. [[2,0,3],
[0,1,0], | [2,1,3],
[3,3,3]] | [2,0,3]]
'''
Extending 13 and 14 to a 5x5 (second pass) results in the following:
'''
15. [[2,2,2,2,2], | 16. [[2,0,0,0,3],
[0,0,0,0,0], | [2,0,0,0,3],
[0,0,1,0,0], | [2,0,1,0,3],
[0,0,0,0,0], | [2,0,0,0,3],
[3,3,3,3,3]] | [2,0,0,0,3]]
'''
A further generalization of 13 and 14 resolves some offset issues and leads the following in the 5x5 case. Although, care needs to be taken to avoid duplicating work of previous passes.
'''
15. [[2,2,2,2,2], | 16. [[2,2,0,3,3],
[2,2,2,2,2], | [2,2,0,3,3],

[3,3,3,3,3], | [2,2,0,3,3],
[3,3,3,3,3]] | [2,2,0,3,3]]
'''
Leaving the outer/inner hull intact:
The goal of the above is was to reduce the number of points and I included points in the hulls in that as well. If it is desired to only remove points between the hulls, then each pattern can check for more than two neighboring points only removing the point if they don't exist. The most extreme example would be the following 3x3 pattern, where the center point is only redundant if it's completely surrounded. Using a 5x5 pattern first instead of 3x3 would make the outer/inner hull as 3 points thick and has no effect being applied after any 3x3 pattern:

I have an interesting problem I'm trying to solve. I have this donate button that's created using the following the css.
'''
#donate-button {
width: 211px;
position: absolute;
background: #FFBC2F;
color: #FFF;
left: 1140px;
right:1340px;
z-index: 30;
top: 0px;
transition:width 2s;
transition:left 2s;
transition:bottom 2s;
}
'''
And the css transition effect I want for this is that the donate button's orange background to expand. It will expand leftwards, towards bottom left, while the top and right frame of the button remains intact in the corner of the browser.
I tried applying the following css transition hover property like so:
'''
#donate-button:hover {
width:33%;
left:73%;
bottom: 53%;
}
'''
The donate button only does the resizing on the bottom frame, but not the left frame and its width. But I'm suspecting I didn't know how to apply the transition delay and duration times combination so I couldn't really quite get the correct effect...
Can somebody point me to the right direction in how I can achieve this type of effect/animation? Any ideas?
Let me know if you need more info. | '''
transition:width 2s;
transition:left 2s;
transition:bottom 2s;
'''
You are the 'transition' property here two times, so that only the last value finally "survives".
You have to put all three values you want to animate into 'transition' property,
'''
transition:width 2s, left 2s, bottom 2s;

7,184,037 | 1 | 7,184,072 | I have some question regarding fb app ticker, I already ask this question on facebook development forum but its been a few days now and to no avail. You see, I have develop my very first facebook app called <URL> but every time I use it, my app ticker on the top right corner of my screen is showing a different name. I tested it on my brothers fb account and its just the same. But whenever I change its name, eg. adding "z" at the end like "MagMeUpz" it shows as it is. But when only "MagMeUp" it shows a different name.

28,940,053 | 1 | 28,943,698 | I have been trying to add custom fonts and custom sizes in select boxes provided with the 'RichTextArea' of Vaadin.
<IMAGE>
How do I do this? | There is no "server-side" way to handle this (up to including Vaadin 7.4). As the <URL> states:
> 'RichTextArea' inherits 'TextField' and does not add any API functionality over it. You can add new functionality by extending the client-side components 'VRichTextArea' and 'VRichTextToolbar'.
So now have a look at the source of 'VRichTextToolbar' and see, that the font lists are build by private methods called in the c'tor. So basically you would have to write it for yourself. Then you would have to learn, how to actually add all those functionality on the client side.
So other tricks to make this work are: Use CSS to hide things from the toolbar (not feasable in your case, you want might want to also add) or use Javascript to add/remove/manipulate things. Of course this is very fragile in the long term.
In the end there is only one sound advice (at least for Vaadin up to 7.4):
Use an addon:

15,444,418 | 1 | 15,444,993 | I've been an old project. I found when the old programmers tried to use the 'SetFocus()' of 'TWinControls' they surrounded them in try/catches with empty catch blocks. Thus swallowing the exceptions.
The default behavior of the program is to set the focus if the control is enabled. In order to do that I created a function which I can pass the 'TWinControl' to:
'''
void SafeSetFocus(TWinControl *Control)
{
if(Control->Enabled && Control->Visible)
{
Control->SetFocus();
}
}
'''
This code works for most of the program, however I found that in one area that I still get a Debugger Exception of 'Cannot focus a disabled or invisible window'.
I thought that the issue might be related to the parent, so I tried the following adjustment:
'''
void SafeSetFocus(TWinControl *Control)
{
if(Control->Enabled && Control->Visible &&
Control->Parent->Enabled && Control->Parent->Visible)
{
Control->SetFocus();
}
}
'''
This changed did not solve the issue. Because of this, I realized that the window may not necessarily be the parent. So my question boils down to:
Is there a way to determine what the window of the 'TWinControl' is and check to see if it is visible? This assumes the exception is accurate... otherwise if you know what the issue is, please share your knowledge :)
---
I've tried to determine the class name of the ParentWindow by the following code:
'''
String parentWindowClassName = ((TObject *)(Control->ParentWindow))->ClassName();
MessageDlg("parentWindowClassName: " + parentWindowClassName, mtInformation, TMsgDlgButtons() << mbOK, 0);
'''
The first line of code gives an access violation when I run it... any thoughts on a different way to try to determine the info?
'CanFocus()' with just the control doesn't work. 'CanFocus()' for the control and parent doesn't work, see screen shot.
<IMAGE> | Thanks goes out to @KenWhite for his suggestions in question ( <URL>
His suggestions in that question lead me to the answer. Below is the code others might be interested in:
'''
#include "winuser.h"
...
void SafeSetFocus(TWinControl *Control)
{
THandle* hWnd = (THandle *)(Control->ParentWindow);
bool parentIsVisible = IsWindowVisible(hWnd);
if(Control->Enabled && Control->Visible && parentIsVisible)
{
Control->SetFocus();
}

The 'sprintf' pads the date with 0 on the left if it is only 5 characters and otherwise leaves it as 6 characters and then we convert that to 'Date' class.

Can anyone help me with this. I feel like I am probably making a mistake somewhere in regards to creating and loading custom uiviews from xibs.
If you require anymore information let me know. Many thanks.
When creating a custom view using a xib DO NOT set the files owner. Instead create all your IBOutlets and IBActions as you normally would and then to hook them up open the Utilities tab and control drag from there.
<IMAGE> | > * Files owner = to my custom class
Wrong. Files owner should be empty. The view itself is files owner. It means that you should connect all actions and outlets with 'ContactUsView' in your xib.
> [[NSBundle mainBundle] loadNibNamed:@"ContactUsView" owner:self options:nil]...self = (ContactUsView *)object;
After you passed 'self' as 'owner'parameter. You changing it. Which means that previously allocated 'ContactUsView' ('self') will be destroyed since '-loadNibNamed:owner:options:' do not retain it. If you apply my first advice you should send 'nil' as 'owner' parameter
'for'loop here is not necessary use just 'array[0]', because this is always your view if you have valid views hierarchy in your xib | |
11,119,333 | 1 | 11,119,423 | <IMAGE>So, I'm almost done with the functionality part for the app I'm developing and now the graphic designer gives me a png image I have to match the xib to. The image has a 'search agent' section with select country,region,language,type of property and two textfield. Originally in my xib I had separate buttons for each and two textfileds, and the button action would give me pickers to select country, region etc. So the png requires me to put all these into a tableview. Is creating tableview with buttons and textfields better or having them separately on the view itself? I know this is not a programmatic doubt in specific but I really need to know which is better. This is my first ever app and I'm really clueless.Thanks in advance. | It really depends on what you want, often people like to use tableviews simply because they group the elements nicely, this is very common in login screens for instance.
But that does not mean one is better than the other is really just a design choice. That being said having buttons inside tableviews can create issues at times, since the response chain is in the tableview and in the button.
For your case I would recommend not to use a uitableview. |
