Why does changing the width and height of uiComp not affect the Sprite? Wouldn't UIComponent provide Sprite with a Graphics object, which limits that area where Sprite can draw?
I have a component ObjectHolder which extends UIComponent that holds many children UIComponents. However, after using addChild() to add these children to ObjectHolder, its width and height remain zero. Is it possible for the UIComponent to automatically expand to the size of its containing children components?
public class ObjectHolder extends UIComponent
{
public function ObjectHolder()

I created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.
package {
import flash.display.*;
public class ScrollBar extends Sprite {[code].....
For example, if I say:
ActionScript Code:
public class Chart extends Sprite {
public function Chart(myHeight:Number, myWidth:Number) {

the problem is that button is added, but is not displayed. if i do reversed - add sprite to uicomponent - everything works fine, but this way it doesn't work. i tried to use invalidate functions for button etc... even tried making "circle" as UIMovieClip, but no luck - button is still invisible. also if i simply do "addChild( button );" - it is shown,how can i add a button inside a sprite?
Here is some code I have.

_buttonUnderline = new Sprite();

When the Tween takes place though it not only changes the width, it changes the height as if it were scaling it up in both directions. Why does this behavior take place? And how can I get it so that only the width changes? I have also tried using scaleX as the property but it does the same thing.
In a previous thread I asked a question about setting the width and height of a sprite subclass in its constructor method. One of the responses has puzzled me since I read it:
"Setting width and height only makes sense if you're adjusting the width and height of existing content, and the Chart (Sprite) has none at that point."
I don't understand that; what if you're adding children to the sprite that depend on those dimensions?
Here's a simple app which draws a red circle inside of a blue box which demonstrates my confusion as well as one other issue. The full questions are at the bottom.
Main.fla:
import Box;
var myBox:Box = new Box(200, 200);addChild(myBox);myBox.drawCircle();
[Code].....
Question 2: In this example, the dimensions of Circle are based on the width of its parent Box sprite. Is there a more elegant way to pass the dimensions to the circle? I ask because in my actual project (a chart) the plot area contains a lot of screen locations that must be passed around when I add new objects such as grid lines and markers and passing around the coordinates as parameters seems awfully messy. I'm just not sure how else to do it.
I got a screen to display objects in a sprite that covers the stage. ok I got a screen to display objects in a sprite

I know this might seem like such an easy issue and I can't understand why I cant figure it out but none the less I can't and I've just about given up. Here's the issue:
I have a sprite container which is supposed to hold a bunch of thumbnails to videos. I am able to populate the container with all the videos and the whole works but obviously if I add a bunch of videos its going to exceed the size of the flash document so I need to add a UIScrollBar (which I did) now the scrollbars target is set to the container but isnt allowing me to scroll and if im correct this is because the container doesnt have a set height. So Im trying to set the height of this container but the second I try setting the height or even width all my thumbnails I used to be able to see are gone! It's as if the size is being set to 0 when its not I've even tried to set it to a specified size just to test and nothing.

I am working on a 3d zoom function. How can I calculate it it best? I have a placeholder_mc:
width: 400
height:400
_x:0
_y:0
In the placeholder_mc I have 10 obj_mc's:
orig width:400, scaled in placeholder_mc: _xscale=20
orig height:400, scaled in placeholder_mc: _yscale=20
the _x and _y are random positions
Now I need a formula that make the placeholder_mc zoom into obj_mc inside and the placeholder_mc must be _xscaled, _yscaled so that the width and height of the clicked _mc are exactly 400x400.
for the _x and _y I use.. onEnterframe=
placeholder_mc._x=placeholder_mc._x+(placeholder_m c.obj_mc._x-placeholder_mc._x)/8;
placeholder_mc._y=placeholder_mc._y+(placeholder_m c.obj_mc._y-placeholder_mc._y)/8;
So this makes the placeholder_mc move to the correct position of the clicked object but how can I scale it now the placeholder_mc so that he moves and scales correct?
I have some custom components, that derived from UIComponent. I overloaded the updateDisplayList so they have custom look. I've created a layouter that lays out these custom components, but to place them correctly, I have to know the custom componets width, height. They are created dynamically. After all of them created (creationCompleted event fired for every), i try to laying out them, but width/height property is still 0. I am also tried to add them to a canvas, before the layout process.
how to create custom UIComponent that placed dynamically, and get to know the width and height of it.
With the use of the mx_internal namespace I can set width and height (using the internal $width and $height fields), and it looks like it is working. But not so clean/good solution.
Is it possible to set the height of the sprite depending on the height of an textfield inside that sprite? I'm creating a box with a textfield inside it, but I want the box to be sized depending of how much text it is in the textfield..
View 9 RepliesI am trying to reference to top level (stage) width and height of the main stage for the placement of something located inside a movieclip on the stage.
My code is:
Code:
my_loader.x = (stage.stageWidth - my_loader.width)/2;
my_loader.y = (stage.stageHeight - my_loader.height)/2;
But this seems to just relate to the width/height of the mc that my_loader is nested in...
I have tried the following and had no luck:
stage.stage.stageWidth
root.stage.stageWidth
parent.stage.stageWidth
MovieClip(root).stage.stageWidth

View 0 RepliesI would like to use a movieclip to load a flv video. The problem I have is that I want to change the video dimensions. I've tried several software to change the video dimensions but as far as it seems all of them keep the same height-width ratio than in the original video. Is there any software that would allow me to change the height and width without keeping the same height/width ratio as in the original video file?

Is there a way to set the pageheight and width? According to adobe help it's read-only.
why I can't get the width of a Sprite when it has components in it.

View 1 RepliesI have an actionscript, which makes a dynamic image wall. It gets parameters from FlashVar and changes the width and height dynamically.
When I use
[SWF(width="584",height="290")]

Top of the picture with SWF tag and the bottom is without SWF tag.

View 1 RepliesI'm trying to set width/height of a FlexSprite object in ActionScript but it doesn't seem to work at all. I'm still a rookie when it comes to ActionScript and I don't understand why I can't set the dimensions of that object.

I plan to add other objects inside the FlexSprite and I need to set their dimensions explicitly as well so I really need to figure out how to do that.
I am loading an external swf using the SWFLoader component. The swf that is being loaded is masked so that only a portion is being shown. However, when it's loaded the actual size of the swf (loader.content.width/loader.content.height) is the complete swf including the masked area. Therefore, the loaded swf does not display properly in the itemrenderer Is there a way to to grab the size of the just the masked area as opposed to getting the size of the entire swf's contents? also i need to re size the masked area
