Re: [flexcoders] What comes after FlexEvent.INITIALIZE and FlexEvent.CREATION_COMPLETE?

Hi Ben,

Why don't you do this?


// **** SuperCheckBox.as ***
package
{
import mx.controls.CheckBox;
import mx.events.FlexEvent;
import flash.text.TextFieldAutoSize;
import flash.events.Event;

public class SuperCheckBox extends CheckBox
{
public function SuperCheckBox()
{
   super();
}

override protected function createChildren():void
{
   super.createChildren();
   if(textField)
   {
      textField.wordWrap = true;
      textField.autoSize = TextFieldAutoSize.LEFT;
      textField.border = true;
   }
  //dispatchEvent(new Event("newChildAdded", true)); // Why do you do this?
}

override protected function measure():void
{
   super.measure();
   measuredMinHeight = measuredHeight = textField.height;
}
}
}

Peace, Mike

PS is ther need to call that newChildAdded event?

I believe, you should use INITIALIZE in your case. I see, you are setting measuredMinHeight in doStuff (..) method..

Initialize would dispatached before any layouting or measuring happens (or before updateDisplayList (..) is invoked?)..

However, please check out..

Hello, I have created a CheckBox whose label can accomodate multiline
text by constructing a CheckBox subclass (mockingly) named
SuperCheckBox. I am adding a set of them to a VBox inside a loop, but
in order to get them properly spaced (not overlapping), I am having to
call both FlexEvent.INITIALIZE and FlexEvent.CREATION_COMPLETE. I know
I am doing something wrong and shouldn't have to call both, but can't
figure out which event is fired once the whole SuperCheckbox component
is done resizing its text box. Any help is appreciated; my code is below.

// in my Canvas
vb = VBox(addChild(new VBox()));
vb.setStyle("verticalGap", 20);
vb.addEventListener("newChildAdded", updateVBox);

for(var i:int = 0; i < labelsArray.length; i++)
{
var cb:SuperCheckBox = new SuperCheckBox();
cb.label = labelsArray[i];
cb.width = 400;
vb.addChild(cb);
}

private function updateVBox(event:Event):void
{
vb.invalidateDisplayList();
}

// **** SuperCheckBox.as ***
package
{
import mx.controls.CheckBox;
import mx.events.FlexEvent;
import flash.text.TextFieldAutoSize;
import flash.events.Event;

public class SuperCheckBox extends CheckBox
{
public function SuperCheckBox()
{
super();
addEventListener(FlexEvent.INITIALIZE, doStuff);
addEventListener(FlexEvent.CREATION_COMPLETE, doStuff);
}

private function doStuff(event:Object):void
{
this.textField.wordWrap = true;
this.textField.autoSize = TextFieldAutoSize.LEFT;
this.textField.border = true;
measuredMinHeight = measuredHeight = this.textField.height;
dispatchEvent(new Event("newChildAdded", true));
}

override protected function measure():void
{
super.measure();
measuredMinHeight = measuredHeight = this.textField.height;
}
}
}

Thanks,
Ben
