Flex :: Add Uicomponent Inside A Sprite?

Apr 15, 2011

i want to add UIComponent inside a spite. here is the code:

private function make() : void {
var circle : Sprite = new Sprite();
circle.graphics.beginFill(0xFF0000, 0.2);[code]......

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?

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?

ActionScript 3.0 :: Flex Getting Width Of Sprite With Component Inside It?

Jun 3, 2009

why I can't get the width of a Sprite when it has components in it.

For example

Code:

addChild(foo);
var comboBox:ComboBox = new ComboBox();

I'm assuming the component possibly isn't set before I'm trying to get the width?

Actionscript 3 :: Resizing Image Inside UIComponent?

Aug 26, 2011

I have a UIComponent and inside it I put a loader (which loads an image file).

THE PROBLEM: Even though I resize the UIComponent(to a square), it will still follow the size of the image in the loader. But when I resize the image in the loader, it will become stretched. What I want to do is have a container(UIComponent) that has a fixed square size and after the image has been loaded it will just fit in the dimention of the container without being stretched.

Actionscript 3 :: Drawing - Cut A "hole" Inside A Rectangular Sprite To See The Sprite Underneath?

Feb 3, 2010

Everytime I google this question I see confusing information about masks and blends, none of which seems to directly apply to what I think should be an easy thing... There are three Sprites involved here...the lowest layer sprite is pretty much a background. I want to overlay a translucent Sprite on top of the background and then I want the third, top-most Sprite to act as a hole, so that the area inside the third Sprite is completely transparent, so that the background sprite is completely visible. How would I go about doing this dynamically (i.e. dynamically drawing the masking sprite and hole using the Actionscript graphics calls)?

Flex :: UIComponent Extended Class Isn't Showing UIComponent Extended Class

Aug 18, 2009

I have 1 class (that is extending a UIcomponent) that is representing a component. In that component I create different instances of another class that is also a UIComponent but this class doesn't show up in de first class. I see that it is running and that it has the correct hights but I got the feeling that it doesn't show up with this hights. If I trace I see the width and height is 200 X 200 but there is still nothing visible in my component.

Flex :: Update UIComponent Size?

Feb 23, 2010

I've created a AS3 class which extends UIComponent so that I can easily add it to my MXML layout. It works fine, but I'm trying to figure out how to update the UIComponent width and height dynamically. I want my super UIComponent to draw a border around the content, so I need get the specific 'content' dimensions in order to do this.

I understand the idea of UIComponent is that you are supposed to specifically set the width and height... but I am literally only extending it so that I am able to use my custom component with MXML easily.Is there a method in which I can get the width and height of a UIComponents 'content'?

Flex :: UIComponent Click Handler?

May 27, 2010

I'm trying to put a label and an image on a UIComponent, side-by-side. I want to use UIComponent for efficiency reasons, and the entire component is more complicated than just a button with an icon.

I'm trying to get a click handler on ther entire UIComponent so that when a click happens on either the label or the image, the same [click] event handler is called. If I add a click handler on the root component, it works, but when I introduce space between the label and the image, the space between them becomes un-clickable. I produce the space by using the move(x,y) method for the label and the image with a small gap between the x/y coordinates.

Flex :: What Is The NonInheritingStyles Property On The UIComponent For

Nov 10, 2010

What is the nonInheritingStyles property for on the UIComponent?

Is this a list of styles that the component does not inherit from the container?

Or is this a list of styles that have been set inline or in code so the component is just telling me that they are NOT inheriting from the container?

If it's the first why are their values set for this properties?

Flex :: Games - Using Canvas Versus UIComponent?

Oct 10, 2009

For developing simple games with the Flex SDK, what are the consequences of using a Canvas object, versus a UIComponent object, as a drawing surface? Are there performance issues with either one? Are the methods generally the same? Searching around, it seems that most sample code I've found uses UIComponent. Is this just customary, or are there reasons?

I already know one odd difference - I had developed a simple Pong game using:

public class MyGameCanvas extends UIComponent

and then decided to replace UIComponent with Canvas. This caused the line to fail:

[Code]...

However, I have to confirm something, being new to Flex and the various terminology. I'm presuming that people mean I should not be using MXML for games, when they said Flex SDK. Since I thought the Flex SDK was what provided the compiler that generates .swf files. Otherwise, where/how would I even compile AS3?

Assuming that's the case, then my question would be about the suitability of using both MXML and AS3 for (simple) games. Based on what I've read about both, it seemed like the intended use of them was MXML for the interface elements, and AS3 for everything else. Is the overhead that bad for MXML?

Flex :: Flash - Custom UIComponent Disappearing?

Aug 3, 2010

Extremely frustrated with this. I've created a simple class that extends the UIComponent. I create an instance of this class in a parent class and utilise the 'addChild' method to add it to the parent. I've overridden the 'updateDisplayList' method of the extended UIComponent to add my own drawing routine using the 'graphics' object.

My problem occurs when I start attempt to change any of the following properties (x , y , width, height) either directly or using 'move' or 'setActualSize' because the UIComponent will no longer display - prior to changing any of these properties the object displays fine. I know the object is still there, the 'updateDisplayList' method is still being called (as I'm calling 'invalidateDisplayList' after each change) and it correctly reports the changes.

Flex :: Drag And Drop From Datagrid To Uicomponent?

Aug 10, 2010

I'm trying to drag an item from a datagrid and drop it onto a UIComponet. Basically I just want the UIComponent to know that something has been dropped onto it and allow it to access the data of the dropped item.

I thought just listening for the drop event would do it but it seems not.

I found lots of documentation on dragging from one IList to another but nothing for this.

<mx:UIComponent xmlns:mx="http://www.adobe.com/2006/mxml"

Flex :: Parent And Owner Property Of UIComponent

Jun 30, 2011

I'm trying to understand the difference between the owner and parent properties of the UIComponent.

<s:Panel id="panOne" title="Success">
<s:Label id="labOne" text="Hello World!!"/>
</s:Panel>

In the above code, labOne.owner.id returns panOne and labOne.parent.id returns contentGroup.

I understand the owner property refers to the parent container of a component (Label in this case). But what does parent property actually mean? I think it relates to some skin concept which has a with id value of contentGroup.

exact difference between these two?

There is another link in the link provided by you. It explained these two terms very clearly. That link is: Gumbo DOM Tree API - Functional and Design Specification

I have pasted below the best lines from that page.

The parent of a visual element is the container directly in charge of laying it out. The owner of a visual element is the component that logically owns it. If a Button is in a SkinnableContainer, its parent is the contentGroup while its owner is the SkinnableContainer.

Flex :: Get Width Of Dynamically Created Custom Uicomponent?

Jul 15, 2009

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.
