If I have a container, and I set clipContent to true, how do I get the total height of the children inside it? Is there a method for doing this without itinerating through every child and summing the heights?
View 1 RepliesI have code like the following:
<s:VGroup gap="10" id="group" height="100%">
<s:Label text="This is page 2" />
<s:Button content="Resize Canvas" click="resize(event);"/>
<mx:Canvas id="photoCanvas" color="#567898" backgroundColor="#125567">
</mx:Canvas>
</s:VGroup>
I don't understand why the following does not work:
Pushing the Button resizes the photoCanvas's height (gets taller or smaller). Since the photoCanvas control is a child element of the VGroup shouldn't the container update itself to the new height? The Vgroup has ALWAYS the same height, no matter what the (total) height of the children is! I would like the VGroup to adjust itself and get a height value equal to the sum of its children heights. Is this not possible??
I need to resize a Group using myGroup.height = 0. And it works, but myGroup's children are still visible, I do not know why...

I'm currently working on a custom component which extends Canvas (let's call it SuperCanvas) ; it's basically a container that let you zoom & pan its contents. It would be too long to explain why, but I can't use scrollRect, so I was forced to declare a Canvas object (called innerCanvas)... inside my SuperCanvas (I know, not very nice =/) I would like to know if there's a proper way to "redirect" the creation of my component's children in this canvas.

I'm using as container for my LinkButtons. I would like to know
1) How can I remove the space between the items in my Tile container.
2) How can I set dynamic width for my items (at the moment they all have the same width regardless the width of the included component)
3) How can I avoid to display scrollbars if the items are not included in the container
I'm using an accordion container that has it's creation policy set to auto. One of the accordion's children is a spark border container that has a data grid within it. Currently, I'm using the data grid's creationComplete property to call a function; similarly, I'm using the dragComplete property to call another function.
How can I add listeners for events (creationComplete & dragComplete) via actionscript? The obvious problem is that the accordion does not create all its children on creation (nor do I want it to), so I can't simply use something like: datagrid.addEventListener(...)
I have a VBox inside a Canvas. The 'red bars' are custom components based on 'Canvas'. All red bars are of equal height. I have 20 red bars inside the VBox. The scrollbars visible in the screenshot are the Canvas's scrollbars. The scrollbars of the VBox are disabled using verticalScrollPolicy = off.
Without scrolling, only 16 red bars (and a part of the 17th bar) are visible. However, when I scroll down the Canvas I expect to see the remaining red bars - but the bars that are not visible when the application starts don't get 'drawn'. What am I doing wrong? I want the user to be able to see the 17th - 20th bars when the Canvas is scrolled down.
I'm having sizing issues with a TabNavigator. The direct children of the TabNavigator are Canvases, and within these I am adding Images. I'm trying to resize the images to fit within the Canvas without scrollbars. The Canvas height is set to 100% of the parent, which is the TabNav. Then I'm setting the image.height = parent.height *.9. The result is that Flex is generating scrollbars because the images are too high. It appears that the root cause is that the height property of the TabNavigator is the height of the entire component, including the height of the tabs. I'm assuming therefore it also contains that little strip of space between the tabs and the children of the TabNavigator. This makes sense, but is there a property that returns only the height of the children? I'm aware of the scrollbar policy properties and I've experimented with those. I know I can also try a different multiplier for the image size to get it to fit. It just seems like there should be a property to get the size of the space for the children.
View 1 RepliesI have a function I wrote that gets the height of the application without scrolling. Meaning the height it would need to be to not have to scroll.
[Code]...
This function works well but the problem is knowing when to call it. I planned on calling it after I add/remove any children from it. However thats still too soon because I don't get the correct height yet if I run it then. The fix I currently have is using a Timer to call the function about 300 milliseconds after a child is added/removed which seems to work well but I think this is a very risky fix. So I was wondering a better solution. I am thinking there has to be some sort of event I can listen for that will tell me when its ready for me to run this function, I just don't know what event that would be?
Is there an easy way to make a parent container (eg Group) resize when it's children resize?
Below is a little example app. When I put the 200x200 'food' in the 'stomach' the stomach & it's containing 100x100 'body' should resize to contain the food.

If I've got a Container with a child component that is off either the top or the left hand side:
Is there any way to get scroll bars to show up? ie, so I can scroll up and get the button back in view, the same way I could if the button was off the bottom right side?
Flex's new States re-parents visual items that are marked with includeIn/excludeFrom. If I have a Group (MainGroup) with 5 children/elements that are state controlled, is there still a way to get a reference to MainGroup's children? mainGroup.numChildren and mainGroup.numElements don't work since the children are re-parented. At best, they show 1.

<s:State name="view1State" />

I have a custom component extending Group and containing a viewstack child. The component is coded in actionscript.
When instantiating the component in mxml like so:
<components:CustomGroup width="100%" height="100%">
<mx:HBox backgroundColor="0xDDFF11" width="100%" height="100%" />
<mx:HBox backgroundColor="0x22DD63" width="100%" height="100%"/>
</components:CustomGroup>
...I would like to override whatever function that adds the children to the parent Group and add them to the child viewstack instead but I can't seem to find where the adding occurs. Breakpoints in addChild and addElement shows that they are not called during the add.
what is the actual height of a container in Flex without scrollbars? Height and measuredheight seem to tell me what the visual height of a container is, but I want to know that number plus any height that is being 'hidden" below a scrollbar.
View 2 RepliesI have a ViewStack which is dataProvider for a TabBar. There are two VBoxs as children for this ViewStack. It works fine with absolute values for width and height for these VBoxs, but when specified in percentages, the VBox uses all the available space (100%) for any percentage value. find the code and screen shots below.
how can children of a ViewStack be aligned to center? There is no horizontalAlign property for ViewStack and it is not working with horizontalCenter= "0".
Code:
<mx:ViewStack id="viewStack" width="100%" height="100%" selectedIndex="0" horizontalCenter="0" textAlign="center">
<mx:VBox label="Tab 1" width="25%" height="10%" borderThickness="2" borderColor="red"

I am trying to increase the height of container with increase in the number of contents inside the container. Like in my case i m using tileList inside tabNavigator , when I put contents inside the tileList, the height of tileList does not increase beyond vertical height of the viewport. It puts scrollbar on the container. I want to increase the height of an flex container with increase in the contents and introduce scrollbar on the browser with increase in contents in the flex container.

Apparently I can get the desired behavior if I change HBox to Canvas but I would still like to know how to accomplish this with a HBox and why it differs from Canvas.
I've created a dynamic text field, and set autoSize to true, so it can grow was tall as necessary. I then want to use the _height value to size a container graphic (speech bubble). Here's the (simplified) code:
[Code]....
Returns 19.6 followed immediately by 35.2. It's as though reading txt._height causes it to recalculate, so it's correct the second time. I also tried the textHeight property, which also seems to get recalculated after _height is accessed. This sequence, for example:

How do I find the total maximum width and height of a movie clip with respect to every frame of that movie clip?
So for instance if the movie clip was circles of radius 5 registered at their center at various positions where:
frame 1:circle.x=-30
frame 2:circle.x=0
frame 3:circle.x=30
The total maximum width of movie clip would be 30--30+5+5=70.
I have a little trouble in managing the children my container. The fact is that it has a lot of children and their y coordinates are very random.
Is there anyway i can order them by y coordinates that the lower will be in the front and the higher with be in the back?
is it something that that I can do with 2 "for"?
Well I'm starting to really enjoy AS3, my next question then is this: In AS2 I'd often remove all movieclips with something like this:
PHP Code:
for(var i: String in container) {
container[i].removeMovieClip();
}
Is there something similar in AS3 that I can do without resorting to maintaining an array of references to each child of my container?

I am having trouble determining where to add my removeChild() statement to clear multiple movieClips from a container mc. I know I need to determine if the container movieclip contains anything. I don't know how or what I should put and where to put it. If I can determine if my container mc has movies in it, I am assuming I can just declare it again (i.e
PHP Code:
panel= new MovieClip();
)to clear it. Am I correct?
[code].....
At one point in my script I'd like to check a MC for the number of children and limit this number to 3. For that I use this script:
Code:
if (container.numChildren > 3){
for (i = container.numChildren; i > 3; i--){
container.removeChild(container.getChildAt(i-1));
popError('Horizontal nur 3 Elemente!');
}
}
This somehow works fine if there are 4 or 5 children in the MovieClip, but as soon as there are 6 or more, it throws an Argument Error #2025 and does not remove anything. BTW it does not make difference if I use container.removeChildAt(i-1);
i'm getting the #1010 error... code below:
Code:
var curProject:int = 0;
var curExample:int = 0;
var container:MovieClip = new MovieClip();
im.addChild(container);

I can't come up with a function that will collect the names of the children in a object container and put them in a array.
