Flash :: How Do Skinned Flex UIComponents Capture Mouse Events
Jul 29, 2009
If my understanding of Flex is correct, skins in Flex are just DisplayObjects that are added as children to UIComponents to create the visual representation of the object. But if my understanding of the Flash event model is correct, if there is a non-transparent DisplayObject on top of another, mouse events will go to the topmost DisplayObject. The overlapped DisplayObject won't receive any mouse input.
So how is it that skinned Flex UIComponents work at all?

I'm currently coding a Floorplan editor with Flex 4.I have a Floorplan Grid that extends the spark Group class. This Floorplan Grid will contain objects that extend the UIComponent class. I want the user to be able to select multiple objects on the Floorplan and be able for moving and resizing.
I'm just wondering if it's possible to have multiple objects being "focused" using the FocusManager, kind of like selecting multiple objects in Photoshop /Illustrator.

I have a canvas called Host with many UIComponents as children, sometimes up to 1000 or 3000 items. This is fine for now, as they are not interactive. But, I have added a 'marker line' (a 1 pixel wide UI Component with a colored background) to the canvas which follows the mouse movement. When this UIComponent is added to the Host canvas and moves, everything slow down to a crawl i.e. takes ages for the UIComponent to move.

I would like to know if flash events (say clicking a button) can be captured somewhere outside the swf. Say, I click on a button and a popup comes up telling which buttom was clicked. The popup should not be a part of swf.

I want to capture flash events in webpage using javascript. By flash events I mean like, clicking a Button, mouseover, entering text in textbox in flash content (websites). I see adobe flash uses Action script code to get the events in eventlisteners. How can I use the same API in javascript?

I have a flash app loaded in an iframe. User mouses down in flash and goes outside of stage. When user goes outside of stage, is there a way to release the mouse capture from flash so that parent receives further mouse events and not the flash app?
In Firefox and Chrome, parent doesn't receive events until the user mouses up
In IE, parent receives event when the user goes outside of stage.

This one's been irking me for a while. When I'm using the mouse scroll wheel to scroll up and down in a webpage, and a flash movie comes into the path of the cursor, the scroll wheel stops working. Also, when a flash movie has focus, you can't use browser shortcuts like Ctrl + L or Ctrl + R.
I'm writing a flex application now and I'd like to find a solution, so that at least my users aren't plagued by this inconsistency of the user interface behavior.
I should think there would be a way to tell flash to propagate such events as the mouse scroll wheel and keyboard input back up to the browser unless they occur in an element for which they are useful, like in a flex textarea. I can't find any solutions out there though, nor even anyone talking about it.
Specifically, how can I make it so that:
When the user is scrolling with the mouse, the browser scrolls unless the mouse is over a flex container with scrollbar, or another component that wants to scroll.When the user presses a button or combination of buttons on the keyboard, it will be propagated to the browser unless there is an active keyboard listener, or the cursor is in a text field, etc.

I am looking to provide some UI functionality using the mouse- I have two distinct UI events to be achieved via mouse
a) change value
b) delete object
I don't seem to have sufficient mouseclick events for both. I am avoiding using the right click as it has some default options(whose signing off will affect the whole project- not just this). I have mouse click used for change value- how do I use the doubleclick as the single-click events seems to get invoked prior?

I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)

Does anyone know an Actionscript equivalent of the javascript getElementsByClassName.
What I would like to do is add a custom 'stylename' to various components which I can then use to get a collection of these objects and therefore process their visibility property.
The idea is I want to hide various components based on what roles a logged in user has - I just want to make this flexible by adding an array of rolenames to a custom property or use the stylename property on a Canvas or Panel etc.

I create some elements( UIComponents, mainly Panels) inside the "mx:Application name=¯tst¯ . I need to cleanup all those UIComponent's on MouseClick event , using Actionscript. Is there any way I access the children elements of mx:Application ( I used var totalChildren:Number = this['tst'].numChildren ; but looks like it fails to access the children list).

The customer I am working for wants to display popup in an AIR application (designed in Flex 4).I will therefore use TitleWindow and PopupManager for this (or NativeWindow could be an option too).
Pretty basic, I can handle this.
Trouble is, this customer would like this popup to be looking as a Fancybox, that is, with the close button, slightly out of the popup.

I'm having a hard time removing some type of shadow in a button control. Here's the button:
The button that's giving me trouble is the "zoomer" one. As you can see, the borders are not straight. I assume that there's some kind of gradient/shadow or sth that's inherited from the default skin.

how to capture the mouse in an air application. I know its possible because the flex scrollbar captures the mouse. I want to replicate the scrollbar's mouse capture.
Try this in a flex/air application window:
<s:Scroller height="500" width="300">
<s:VGroup>
<s:Rect width="100%" height="2000">
<s:fill>
[Code]...
If you press and hold the scrollbar handle and drag outside, even outside the window, the scrollbar still works. It wont lose focus. So it is capturing the mouse.
what I want:
Mouse and touch capture. (Even outside the window while still pressing down the button or touch point)

How do I capture events of an obj behind another?I have a button(btn1) which I am applying a tween to. This tween is responsible for fading the btn out using the alpha prop (to 0). Behind that btn is another (btn2). I am having trouble leaving btn1 in place (same x and y) and being able to press on btn2. I have removed the eventHandler for btn1 but it's still blocking the other button. Other than creating another var and checking in the tween on complete handler is there any way to leave btn1 in place but be able to click through it??

I have a few Skinnable Containers that have children components, such as an image component or a button bar etc. It seems that when I add the skin, the Skinnable container looks great, but all my children components of that container seem to disappear.
Example:
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
[Code]....
In the above example, the Skin works just fine, but the image contained within the SkinnableContainer will disappear.

I have a "large" movie clip and "small" movie inside a "large" movie clip but on it's let's say upper right corner:
Code:
largeMc.addChild(smallMc);[
If i try to catch Mouse.DOWN events on them the following way:
Code:
largeMc.addEventListener(MouseEvent.MOUSE_DOWN, largeClicked);
smallMc.addEventListener(MouseEvent.MOUSE_DOWN, smallClicked);
Then of course both event are captured no matter where i click.Is it possible to capture independent mouse clicks on both of these two movie clips and if so, how can i do that?

Right now all the sounds (78 of them) on my guitar play using the roll_over event but that doesn't give the user much control over what sound is played.
The actionscript im using to play my sounds is this;
for(var i:uint = 0; i < buttonArray.length; i++){
buttonArray[i].addEventListener(MouseEvent.ROLL_OVER, buttonRolledOver);
}
[Code]....
What i want to do is only play a sound with the roll_over event when the left click is held down.

I want to replicate the standard startDrag/stopDrag events with my own routine to alter things a bit, and I run into some kind of event propagation or bubbling problem. Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
mouseDown="mouseDown = true" mouseUp="mouseDown = false"
[Code].....
The problem with this code is that as you drag the object to the right, you will see in the trace that occasionally some random localX values arrive there, resulting in the object jerking from side to side.

im working on:[code]For more detailed comprehension: corner is the black corner with the (i) and 'Promotion', text is some random text that can be displayed in the white remaining space, container contains corner and text, and finally this class contains container!I need to retrieve the event mouseevent.rollover/rollout from corner.And what's wrong?
1. When I put the mask on container (container.rawchildren.addchildren + container.mask = mask) and the dropshadowfilter on container (container. filters = [glow]), I cannot detect the mouse events.
2. When I put the mask on the promopanel (this.rawchildren.addchildren + this.mask = mask) and the dropshadowfilter on promopanel (this.filters = [glow]), I cannot detect the mouse events.
3. When I put the mask in a component and the filter in another, it does not work either.
4. If I remove the mask OR the filter, it works!! But I need them both...
So, does anyone has an idea on how to make this work? I've been trying to look for issues with filters, masks and mouseevents but haven't found anything that could enlighten this issue.

I am implementing an application timeout feature (flex4). What I am finding is that mouse and keyboard events, which I have listened to with :
FlexGlobals.topLevelApplication.addEventListener(MouseEvent.MOUSE_MOVE, resetLastActivity);
FlexGlobals.topLevelApplication.addEventListener(KeyboardEvent.KEY_DOWN, resetLastActivity);
are being masked by the existence of any popup windows. The code is in a component, in the constructor. The component is added to the main application in the block.
How can I get these system generated events to not get stopped by PopUpManager display objects?

Is this the most efficient way to listen to mouse events on the background of a group?
<s:Group width="200" height="100" rollOver="group1_rollOverHandler(event)" rollOut="group1_rollOutHandler(event)">
<s:Rect width="100%" height="100%">
<s:fill>
<s:SolidColor alpha="0"/>
</s:fill>
</s:Rect>
</s:Group>
seems pretty minimal, but alpha = 0 is not the most efficient thing out there.

I have a BorderContainer with some instances of spark Line. I need to select this lines by clicking on this. But adding event mouse click listener fails. ASdoc [URL] says that line have only activate and deactivate events. Any best way to detect whether line clicked (use another line class?). I think that catching of clicks in the bordercontainer is bad solution.
