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 function (let's call it testFunction for right now ) on the actions layer in the main timeline There is a movie clip with 15 frames long in the library
i want to add a child of the movie clip on the stage, and call testFunction when it finishes playing
how can i do? i tried to call it in the child but nothing works
Or, is there any way to show child on the stage for only a period of time like 1 second and then remove it automaticly?
this is the code i found out on the web to call a function in the parent swf from the loaded child swf.
in the child swf:
Code: Select allpanel.next_mc.addEventListener(MouseEvent.CLICK, onClick);
function onClick(e:MouseEvent):void{
MovieClip(this.parent.parent).parentFunction();
}

I have a main MovieClip that creates a new instance of an imported class which is a page in the application. This class tries to call a function on the main MovieClip and it's not finding it. I've done this in the past without any problems with separate swf files and loaders, and with movieclips in a library. I'm at a loss on how to resolve this. Here's what I'm doing (simplified for posting):

I have load child swf in parent swf, from child swf i am trying to run my parent swffunction I am trying this code

Lets say I have a Main Document Class called Main. I also have a child class called childClass that call a function from the Main class and is also imported in the Main class. How should I call the function? I tried this , but when calling the function, it's getting me error.
Main class :
Code:
package {
import flash.display.Sprite;
import com.childClass;
[Code].....
I 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 want to call the parent function called "edit_groups()" from the itemRenderer. The code for my itemRenderer is:
<mx:VBox id="vbx_container" paddingBottom="4" paddingLeft="4" paddingRight="4" paddingTop="4" borderStyle="solid"
dropShadowEnabled="true" width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<mx:Canvas width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<mx:Image id="image" width="100" height="100" source="{data.thumb}" scaleContent="true" maintainAspectRatio="true"
complete="{image_smoothing_handler(event);}" trustContent="true" doubleClick="{Call The Parent Function"edit_groups()"}"/>
</mx:Canvas></mx:VBox>
And I call my itemRenderer from an application like:
list_groups_modify.itemRenderer=new ClassFactory(groups.list_groups_modify_item_renderer);
<mx:Label text="{data.label}" textAlign="center" maxWidth="60" toolTip="{data.label}"/>
If I need to call a specific function in the parent application from a child in a flex project, what's the best practice for this? Would it be to dispatch a custom event from the child and have a listener call that function? Or to directly call the function with FlexGlobals.topLevelApplication?
View 1 RepliesI loaded external swf named child.swf from parent.swf. i am having a function called parentFunction() in parent.swf. I want to call parentFunction() from child swf.
View 2 RepliesBasically I have 3 swf, parent.swf, child1.swf and child2.swf
parent.swf loads child1.swf
child1.swf loads child2.swf
child2.swf consists of 7 buttons which when click it will 7 different swf files.
My problem is I want to call those buttons name/instance name to my parent so that when click it will load its corresponding swf file.
one of my problem is that how do i call the instance name of a button from my child.swf to my parent.swf
i have four buttons from my child.swf where when i click btn1 it will load superchild.swf but i want to load that superchild.swf to my parent.swf, like instead btn1 calls superchild.swf to load, btn1 will call parent.swf then on parent.swf it will distinguish that btn1 was click from child.swf and it will now load superchild.swf.
I have a parent class that instantiates a MenuClass and handles transitions between pages.[code]And here's the MenuClass which creates forward and backward buttons. Clicking each will tell the above ParentClass to transitionForward() or transitionBackward() respectively.[code]One one hand, I feel like the MenuClass is too tightly bound to its parent and is thus less reusable. On the other hand I feel like, in the interest of keeping everything self contained, it's not the ParentClass's responsibility to reach into the MenuClass instance and add event listeners there. This seems like there should be some kind of OOP rule-of-thumb to govern this kind of relationship.Is my MenuClass too tightly bound to its parent? And if so, do you have any suggestions that would loosen that coupling?
View 4 RepliesI got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.
View 10 Repliesi am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
View 5 RepliesI got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code:
trace(SpriteP.width + ' ' + SpriteP.height); //100 250.
SpriteP.removeChild(Sprite2)
trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good.
When Sprite2 is rotated at 90:

And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.
i have a swf that loads a swf that loads one swf into that one. i need the final swf (child, child) to be able to call a function on the first swf (parent)
i have tried this:

I have a function in a child that I need to have executed by the parent but I can't get it to work. Does anyone know how to call the function in a child from a parent?
What I'm doing is having the parent load a few buttons and I want to re-use the button swf, but have the parent provide the text for the button.[code]...
May i know how to call child function(layer 2) in parent(layer 1)?
Layer 1 (Parent)
function changeAction():void{
changeColor();
}
This method will give me the error -> Call to a possibly undefined method changeColor.
Layer 2 (Child)
function changeColor():void{
trace("success");
}
I have to access a function in child swf from parent swf. This child swf gets loaded into a canvas object in parent.swf. Everything works fine but I'm unable to call any function that was in child.swf. My code is
Code:
var swf1:SWFLoader = new SWFLoader();
swf1.source = "CHILD.swf";
can.addchild(swf1);
I read on google and then I tried this in parent.swf's code
Code:
var myrequest:URLRequest = new URLRequest("CHILD.swf");
var myloader:Loader = new Loader();
myloader.load(myrequest);
canvas.addchild(myloader);
Now this one throws up a runtime error TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@5934b01 to mx.core.IUIComponent.
I also tried this
Code:
var myrequest:URLRequest = new URLRequest("CHILD.swf");
var myloader:Loader = new Loader();
myloader.load(myrequest);
[Code]....
But in this case my swf does not show up at all and there are no runtime errors too!
How do I resolve this error and how do I then access the function in child.swf?
I have container swf which includes navigation that loads child swfs. Each child swf is loaded then visibility is set to false. Once a child ( an image gallery actually) is loaded it is possible to jump from image to image. What Id would like to be able to do is call a "clean up" function that returns the child to its initial state when anothor nav link ( a different gallery) in the parent is clicked. But I do not know how the syntax is supposed to be written or if its even possible.
Ideally it would look something like this in the parent container swf:
ActionScript Code:
function swapSectionIdentity(e:MouseEvent):void {
setChildIndex(background_home, 0);
getChildByName("identity_mc").visible = true;
[Code]...
the behavior I am attempting to avoid is when a child swf is loaded ( an image gallery) and then the child is invoked to display a particular image in it, afterwhich a main navigation link is clicked the current gallery is set to visible = false and a new gallery is set to visible = true. But when you return to the previous gallery the last image viewed is still showing. I want to be able to reutrn to galleries inital state as it is hidden. make sense?
I need to get the value inside a handler..
ActionScript Code:
public function verifyUser(p:String):String{
var verify:String
var variables:URLVariables = new URLVariables();
var varSend:URLRequest = new URLRequest("verify.php");
varSend.method = URLRequestMethod.POST;
varSend.data = variables;
[Code] .....
It's always returning 'null'. because its not waiting for the completehandler to be completed and just passes the null value of verify..
I have setup a simple video interface. The video player lives in the parent swf. The video list chooser is loaded as a child swf. In this child swf, I have some video buttons nested within two movieclips in order to facilitate the scrolling feature. I am trying to get the movie buttons to load flvs into the component flv player in the parent swf. I have declared the functions in the parent and I am trying to call them in the child:Code in the Parent:
function vid1(event:MouseEvent): void{
pubPlayer.source = 'vid1.flv';
}

how I reference vars/instances from a parent class by using a static function and I wonder if there is a better way to do it.
I have a main document class Main.as with a public static function called mainFunction().
ActionScript Code:
public static function mainFunction( _mc:MovieClip, _nVar:Number ):void
{
// do something
[Code]......
This can be tricky if the static function has many variables from its own class.
How can I make a call to a function in the parent class of the class I'm in.
example:
main class
Code:
package {
import flash.display.Sprite;
public class mainClass extends Sprite
{

I realise that there is some stuff that is missing in the "full" code here, but that's just because I'm to lazy to write it all...
How do I get the "someButton" in the "child_class" to call the "theImportantFunction" in the main class? I know that it is possible to make a "dispatchEvent" in the "mouseClick" function, and then add a eventlistener in the main class.. But is there another way to just call the function directly?
For instance, in the below code a parent can control a SWF child's function "alert ()". But how a SWF child can control parent's function "ReceivingChildMsg()" ?
View 4 RepliesI am adding a child .swf from the parent with a simple button. If this button is then clicked multiple times, the child is added multiple times. So I added the ".visible = false" to the button when clicked so the button cannot be clicked while the child is open.
Now, there is "Close" button on the child .swf that uses "this.parent.parent.removeChild(this.parent);" and would now need to set the parent button back to ".visible = true".
I have tried MovieClip.parent.parent.resetButton(); and parent as MovieClip.resetButton(); and many variations of the code. I get no errors but the code doesn't work either.
I do not want to use external .as files because I will have about 100 swfs to manage in this project, 100 swf is a lot of file management alone without adding 100 .as files on top of it.This is the code in the parent swf file to call the child swf and place it in the page_mc movieclip (note in my final project "child.swf" is replaced with the loading array variable but we're going to keep it simple):
ActionScript Code:
var pageLoader:Loader = new Loader();
page_mc.addChild(pageLoader);
var loadedpage:URLRequest=new URLRequest("child.swf");
pageLoader.load(loadedpage);
Now just for a simple function to call, we'll say we have a box_mc on the stage in the child swf, and when we click the button in the parent swf I want to call a simple function like this to hide it:
ActionScript Code:
function hideBox(event:Event):void {
box_mc.visible=false;
}
how do I call that function in the child swf from a button in the parent swf?
I have this movieClip "Container" and within it on two different frames I have two movieClip/buttons, "pause_btn" and "play_btn", respectively. I would like to call a function on the main timeline on frame two of "Container" where "play_btn" is located.
I think I'm getting close but really have no idea. I know about the visible property and have been considering that, but isn't there a way to call a parent function from within a child movie clip? The code looks like this.
[Code]...
I have a swf that should be able to load another swf in runtime. Then I would like the loaded swf to call a method of the parent, loader swf, like this:
Code:
parent.closeForm;
But when I compile it, it throws this error:
1119: Access of possibly undefined property closeForm through a reference with static type flash.displayisplayObjectContainer.
I've tried:
Code:
if (parent != stage){
parent.closeForm;
}
So flash won't run this code at compile time, but it always throws that error. Here is the code of the LOADER swf:
Code:
private function loadForm():void {
var loader:Loader = new Loader()
var mRequest:URLRequest = new URLRequest(formPath);
loader.load(mRequest);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onFormCompleteHandler);
[Code] .....
How could I write an expression that should call a function of the LOADER swf without having this compile-time error?
