Flex :: VGroup - (Parent) Container Does Not Change Height With Children?

May 13, 2011

I 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??

Flash - Children Movieclips Doesn't Show Its Width And Height According To Parent Movieclip

Jul 19, 2011

I have placed 3 movieclips named mcParent, mcChild1, mcChild2 and 1 textbox in flash. child are childrens of parent movie clip. child1 and child2 both are of sizes 300 whereas parent movieclip is 600px, textbox is placed inside child2 movie clip .

I have made the flash to auto resize according to the screen area. Everything works well, but after resize it resizes parent and all childrens and textbox which is correct. The problem is with the correct placement of textbox on mcChild2. I have seen that after resize, mcParent width and scalex both changes but the child clips doesn't changed its sizes even they are stretched but there sizes are not updated due to which I am unable to get the exact location of where to place the textbox.

Flex :: Moving Children Of A Container (defined In MXML) Inside An "inner Container"

Jan 27, 2010

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.

Actionscript 3 :: Listen When A Mouse Moves Out Of The VGroup Container Or TitleWindow

Mar 8, 2012

I have a popup window. In that popup window, when a user clicks a button and moves out of the popup window, the event should stop. How can I achieve this in flex?

Simply to say, if a mouse moves from the title window or any other container to the outside of the window or component, I want to listen to that event.

I tried with focus out but that fires only when user clicks or changes the component. I also tried with the mouse out event, it also didn't work for me.

how to listen for the event when a user moves a mouse from inside a component to the outside of the component?

Flex :: Listen For Dispatched Events From Container Children?

Oct 5, 2010

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(...)

Flex - Container's Clipped Children Not Visible On Scrolling?

Mar 30, 2011

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.

Flex :: How To Find Height Of Children In TabNavigator

Nov 13, 2009

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.

Flex Get Height Of Children When To Call Function?

Jun 8, 2009

I 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?

Flex :: Width And Height Specified In Percentage Not Working For Children Of A Viewstack

Sep 30, 2011

I 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"

Flex :: Prevent Dragging Outside The Parent Container In Flash?

Nov 22, 2010

I have a canvas onto which I draw shapes like rectangle etc. When I move the shape using my custom mouse down/mouse move handler, the shape can go outside the parent bounds.

I am checking if the child is outside the parent's bound to snap it back:

var bounds:Rectangle = this.getBounds(this.parent);
var p:Point;
if (bounds.x <0) {

[Code]...

The snapInside method gets called when I go outside the left or top boundary. But when the child is dragged outside the right or bottom boundary, I find Flex/Flash runtime automatically expands the parent's height and width. So say the parent size was initially 800x600, if child Y bounds exceed 800 by say 20 pixel, I find the this.parent.height automatically resized by flex to 820!!

How do I prevent the parent from resizing when child goes outside the original bounds of the parent ?
