[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]
View 2 RepliesI got a "preloader" that creates an movieclip and loads an SWF. Now in the loaded SWF i want a close button to go back to the "preloader". The preloader isn't an actuall preloader but some sort of mainclip.Now i tried this:removeChild(MovieClip(e.currentTarget).parent.pare nt.parent)But i get error:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display::DisplayObjectContainer/removeChild()at MethodInfo-6()
View 1 RepliesI'm currently making a platform game and when the player shoots i want to add the bullets to the stage. The players gun class is in charge of adding bullets. The "players gun" is a child of "players gun holder" which is a child of "player" which is a child of the stage. is there a better or more dynamic way for the "players gun" to add bullets to the stage rather than using parent.parent.parent.addChild (bullet);
View 2 RepliesI have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that?Here's my parent:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

if I add a clip to the stage as a child and remove the parent and set the parent equal to null, does the child get collected and removed from memory? What if the child has an image loaded into it as its child?
In my application I'm loading a series of png images as overlays that can be tinted for customizing in this app. When I trace my memory, the basic app idles at 64,000 k. The exact second I load those overlay images it goes up to 205,000k. If I remove those clips and "clear" the stage I should go back down to 64,000 k if everything is removed and collected correctly, right? It's not, it's hanging at 215,000 k. Are my images being cached and that is the reason for the memory staying up? If so, how do I prevent that. Or upon removing the parent of the image how can I un-cache the image.
If a user switches between models and loads several different items then the application actually crashes the Flash environment because of too much memory usage. It also does the same to browsers.
I am trying to access a function that is on my document class for my AS3 project, from a nested class. That is, the Document Class calls Class A which then calls Class B. So I am trying to access a function from Class B, I am trying to use MovieClip(parent).function(); but I am getting error 1120. The MovieClip(parent) (fixed to reflect my document class, etc) works when I try it from other classes but not from this nested class.
View 9 RepliesSimple drag and drop application where mc is dragged out of one parent mc and dropped into another parent mc.All works OK until I added 2 text boxes to the mc's -- one is a non-selectable dynamic text box (a label) which is set by the code, the other is selectable input text that the user can amend.
Finger cursor disappears when user hovers over the section of the mc that contains the text fields (even non-selectable text??) When the user trys to drag the mc by inadvertantly click-dragging anywhere within both text areas it causes this error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.text::TextField@2374a381 to flash.display. MovieClip (same error appears for both text boxes)
The input text box may confuse the user - how do they sometimes click to drag and sometimes click to amend? I need to create an overlay area within the mc that is click-detected for the drag? Here's the relevant bits of code:
var itemArray:Array = [
{iname:"police",ititle:"POLICE OFFICER"},

I have a parent swf which loads many child swfs (though only one is displayed at a time). My intention was to use the loaded SWFs document class to retrieve an array of objects to be assigned a tab index, combine this with the parent's own array of objects and apply sequential tab indices to them all. But what happens is actually that the parent's objects are assigned an index, but the external swf is unaffected. In fact, the external swf retains its automatic tab indexing, when I would expect that having set a value for InteractiveObject.tabIndex, automatic tab indexing would be disabled.
I've seen similar tales elsewhere. Most posts I've read are wanting to load an external swf, give it focus and loop through those objects, then close the swf and return to looping through the parent. However I would like loop through all objects as one. including manipulating the focus manager(s), and basically fiddling with every tab-related property I know.
I've struggled with this for a long time and have thrown in the towel. How the heck do you climb the ladder, then go back down again into another clip?
View 2 RepliesI have been using:
yourbutton.addEventListener(MouseEvent.CLICK,f);
function f(e:Event):void{
Loader(this.parent).load(new URLRequest("newswf.swf"));
}
which was suggested to me in a different post to target the parent loader class, however i now no longer can reference my preloader in the parent swf (extract from the parent swf):

View 1 RepliesIs there any way to know the parent/component which initiates context menu? I have a panel which contains different custom components. i want to open respective popup window of custom component from context menu when user right click on the respective component.
How can i find the parent custom component which initiates context menu?
for ex:
custom compoent: 1. Label, 2. Buttom
context menu Item: properties
On right click over 'Label' opens a context menu which has item 'properties', on clicking properties it should open custom popoup window showing properties of Label. similarly, for Button.
I am trying to listen Event on click of context menu, but it is not useful.

I have a page-like flex application. In my main application is a holder (a canvas) that displays all the pages. The problem is that the components that are loaded inside the holder are bigger than the holder is when the main application starts. The holder height is set to 100% but still he gets scrollbars when I load a bigger component inside of him then himselHow can I solve this problem? And if it isn't solvable would it work correct if I use a viewstack?the holder looks like this:
<mx:canvas height="100%">
</canvas>
But the end of the application is 500 pixels lower so canvas height is 500 pixels high. Now I put a new child inside the holder that is 1000 pixels high.
I have a XML based Tree Control. The XML Structure is recursive, so the children's can have the same Element as the parent. I now want to let the user add and remove the elements. Do do so I need to get the parent element of the selected Item. Following code I already collected together:
var selected:XML = treeControl.selectedItem;
parent.insertChildAfter(selected:XML, newElement);
I just don't know how to get to the selected parents node as there is no such method like treeControl.selectedItem.parent.
Recently I worked in a project using Flex. Its a Photo editing project. I have took a Canvas and take a image in that canvas using the code canvas.addChild(image) . Now i can move the image freely by using moving code. The image move inside the canvas and outside the canvas. I want to move the image/child only inside the canvas not outside. How can i do this?
View 1 RepliesI want to call the parent function called "edit_groups()" from the itemRenderer. The code for my itemRenderer is:

dropShadowEnabled="true" width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >

I have three datagrids inside VBox container. Since I don't want scrollbar in my flex widget i am increasing the height of SWF through javascript, which increases with each addition of row in my datagrid.

Is there a more declarative way to accomplish this? In the latter case, for instance, can I at least replace the variable slideTime with a direct reference to the parent's duration?

View 2 RepliesI have a spark list control whose data is rendered using an itemrenderer. Basically the Item renderer lays out the data within a Panel.
The Panel has a LinkButton, which when clicked needs to pass an Id to the parent application. In the parent application I have a function that dispatches a custom event to its parent. I want to know how to call this function from the ItemRenderer.
I tried using parentDocument.outerfunction etc but it throws an error..
Is it possible to call a child function from within the parent? I know to go child > parent, you can do parentApplication.functionName(parameters);, but what about going the other way... that is parent > child?
View 2 RepliesI have a main.mxml, child.mxml and headermenu.mxml. I click a button on the headermenu that dispatches an event up to the main.mxml which then executes a method in child.mxml. I know this works because I put an AlertDialog in the function I'm calling inside of the child.mxml. The child.mxml contains a drawingArea object that has an erase(). When I call this directly from child.xml it executes, however if I put drawingArea.erase() inside of the function being called by child's parent (main.mxml) nothing happens.[code]...
View 1 RepliesI'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.
I need to access information in my XML. The information I need is not stored on every object in my XML, only on the parent. But how can I check if there is a parent or not, so it wont throw an error when selecting the first object in the tree (having no parents)?

this.parent;
