ActionScript 3.0 :: Target An Event At Object Not In The Display List?

Jun 7, 2010

I'm trying to dispatch a custom event from a custom class (which implements IEventDispatcher) to another custom class (also implements IEventDispatcher) but I cannot trigger the corresponding event handlers.The classes are instantiated at different parts of the application: one on the main canvas and the other on the back-end (data side) of the app. Neither of these is part of the display list hierarchy and I need them to communicate through events.I've looked through adobe docs, the web and Mook's Essential AS3, but have come up with nothing...

ActionScript 3.0 :: Display Object Cannot Be In The Display List More Than Once?

Feb 9, 2009

It's my understanding that a display object cannot be in the display list more that once.So if I add something to the stage shouldn't a second addition of the same object replace the first? for instance:

there should now only be one "myDisplayObject" on the stage.

Is there a way to make a display object always be at the top of the display list?For example, I know you can set the childIndex, i.e:setChildIndex(myDisplayObject, numChildren-1);But is there a way that an object has sensed that something else has been added to the display list and restack themselves accordingly?

Actionscript 3 :: Dispatching From An Object Not In The Display List?

Feb 24, 2011

I have an object that controls another object that is on the display list.

The setup looks like this:

Parent (Main Timeline)
- Child
-- Grandchild --> contains instance of behaviour class that controls the grandchild's movement

I have an event in the "behaviour" that I'd like to reach the parent, but the behavior does not extend Sprite or MovieClip.

How can I get this event to reach the parent?

Actionscript 3 :: Removing Object From The Display List?

May 10, 2011

I have an application that uses a main class to control other MovieClips, adding and removing them as needed, most of them are separate screens or sub menus.

When I leave the main menu and come back to it later from another screen, certain animations and roll over buttons still play, which I don't want, I basically need the main menu screen to reset every time it is seen.

I read up on this and found out that removing the child doesn't necessarily remove it from the memory.

I tried setting the mainmenu to null before moving onto a different screen but this threw up an error, stating that the parameter child must be none null.

how to completely kill my mainmenu when it is not needed.

public function confSubMenuOneScreen():void {
subMenuOneScreen = new SubMenuOne();
mainmenu = null;

[Code].....

This is the example of code that removes the menu and adds another screen, with the mainmenu = null code that throws up the error.

ActionScript 3.0 :: Accessing A Non-display List Parent Object?

Jul 12, 2009

I need to access a non-display list top-level (Parent? Ancestor? What's the correct term?) object from a display list object, and I don't know how.

In my code, ResultX is an instance of my custom class Result. Card is a sprite, a visual representation of the ResultX object, defined inside the Result class and attached (or removed) to the stage via a separate function inside the result class as needed.

I want to refer to the correct Result object when the user clicks on the corresponding card to call a function there. In accessing the sprite manually, ResultX.card works fine, but I don't know how to go upwards trough the path - card.parent (or actually target.parent, since it's done via event) just returns Main, of course.

ActionScript 3.0 :: Bring Object To Front Of Display List?

Dec 8, 2009

I'm trying to create an image class that I can reuse throughout a website I'm making.

When you click an image i want it to expand to fill the screen. When this happens obviously it will have to be at the top of the display list so that none of the other objects on the website are above it. The problem is that I want to be able to use this class throughout the website, even within containers that are beneath other objects so it seems impossible to simply bring it to the front easily?

Edit: Maybe when you click an image it would create a replica on top of the current image but above all the other objects on the main stage - then expand that one instead of the original image in the container? Theres got to be a better method though... I can't imagine this working too smoothly.

ActionScript 3.0 :: Object Does Not Show On Screen Once Re-added To Display List?

Nov 3, 2011

I have an object that is instantiated, then placed into a property within a singleton (single instance) object. When a button is clicked an event is dispatched carrying a payload that references the display object that is held within the Singleton. When the event is heard, my view object adds the object to the display list e.g. addChild().The Item shows. Now If I hit another button an event is dispatched, and a new item is added to the display list via the method above and is seen. The 1st object is removed from the display list Here is my problem. When I click the button to load the 1st Object the above process is executed again but the object does not show.

I can run trace statements from the object that is supposed to be visible and they run fine. I even do a check to see if the visible property is set to true, and it is, but not object is on my screen. Code for this process.

//custom event carries the name of the page aka display object. this is a string
dispatchEvent(new MenuEvent(MenuEvent.CHANGE_VIEW_STATE, event.payload));
//When the event is heard, the following condinial is run

ActionScript 3.0 :: Display List Manipulation Removes Object From Frame?

Nov 16, 2010

I've got these Flash students I TA for a course, and they are doing drag and drop exercises and have come across some weirdness.(They are using a frames based design to represent different pages of activity, with a menu to goto each frame under user control.)At author time:

1. they set up drag and drop as3 for an object on a particular frame.

2. when startDrag is initiated, they moved the dragged object to the top of the display list, so it appears to float above all other objects as the user drags.

at runtime,a problem appears:the object seems to have been pulled out of the frame, and now floats in a display list above any frame that may be advanced to.What's going on here? It's like the object got pulled off the authortime stage and now is disconnected. Going back to the drag and drop frame shows the original object again, reinstanced, along with this copy that got pulled out.

ActionScript 3.0 :: Remove Object From Display List And Memory Which Added Dynamically

Aug 22, 2010

how do we remove object( sprite which has an external swf as it's child ) from display and more importantly from memory yet we still can use the same variable to add  another object (yes another sprite like the one we removed yet has different content).., "
 
i did tried the removeChildAt thing it did remove all the child from the display list but i still can hear sound from video running.

Flex :: Scrolling Of List Control Is Misbehaving?

Dec 22, 2009

I am having this very weird behavior with a mx:List control not scrolling properly.Here is a snippet:

<mx:List itemRenderer="customerRender" x="19" y="257" height="68" width="290" id="orderStatusHistoryList" color="#CCCCCC" rowHeight="35" ></mx:List>

The custom render creates a vBox that is 35 pixels high with some labels in it.Now, my dataProvider, set in the script block,is returning 3 items for the list (say item1, item2 and item3). Because of the height of the list control, only 2 are shown initially.Now for the weird part, when I scroll down the list to see the next item it is all messed up.

Initial display:
Item 1
Item 2

Display after clicking the scroll down button:

Item 2 (expected)
Item 1 (What the ?, this should be item 3)

Display after click the scroll down button one more time:

Item 1 (all wrong)

Now, if I increase the height of the list control,so it has enough room to display all three items, it displays fine.Also,I put a trace statement is the item render and flex is rendering all three items with the correct data.

Flex :: Add Separator Between Items In A Spark List Control?

May 21, 2010

I have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how.

Flex :: How To Set Variable Size For List Control Item

Jun 17, 2010

The following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows. However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this?

<mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" >
<mx:itemRenderer> <mx:Component>
<mx:VBox width="100%" height="150" >
<mx:Text text="{data.commentContent}" />
<mx:Text text="{data.username} ({data.modified})"/>
</mx:VBox> </mx:Component>
</mx:itemRenderer> </mx:List>

To be more clear, I don't want to set the itemRenderer's VBox height to "150" or any other fixed value - but it'll only show one line of the text if I don't do it. So I'm looking for a way out of this. (If the VBox is not inside the itemRenderer, it'll auto adjust height as Text field string length grows - that's what I want.)
