RE: [flexcoders] Flex2 :: Subclassing Button :: How to change hitarea placement
Here's a quick example of a Button subclass which is only clickable on
its left side:
package {
import mx.controls.Button;
import flash.display.*;
public class ButtonTest extends Button {
override protected function createChildren():void
{
super.createChildren();
var s:Sprite = new Sprite();
s.visible = false;
s.mouseEnabled = false;
addChild(s);
hitArea = s;
}
override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth,
unscaledHeight);
var g:Graphics = hitArea.graphics;
g.clear();
g.beginFill(1, 1);
g.drawRect(0, 0, unscaledWidth/2,
unscaledHeight);
}
}
}
Usage:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml xmlns=*
layout=absolute
ButtonTest label=I'm only active on the left side/
/mx:Application

Subject: [flexcoders] Flex2 :: Subclassing Button :: How to
change hitarea placement
Hi,
I was wondering if anybody from Adobe could shed some light on
how to go about adding like two little buttons to a Button?
I have tried with all my heart and cannot find a way to chnge
the hitArea of a button to something smaller than it's bounds.
Are you just adding a click listener to the whole component? If
so, this makes it really hard to subclass.
Can you give me any advice?
Peace, Mike

Re: [flexcoders] Flex2 :: Subclassing Button :: How to change hitarea placement
Well,
Do you have another answer ;-)
This did what I was looking for but, the event effect still is not right.
I am making a drag and drop tab button. I need the button to have the
normal hitarea that the skins use to detect the ACTUAL button click. I
need a 10x10 dragger sprite, button whatever to be on top of the button
skins, this component needs to listen for mouseMove etc.
Then I need a close button on the other side. Now this would be really
easy from my end. I wouldn't even extend button, I would make my own
tab using composition. To me that is more tight thatn what I am doing
to the Button.
The problem with the approach is, Adobe did not program to an interface
but to a concrete implementation of Button in the TabBar. So now, I
cannot override createNavItem() and use my Tab becasue down the chain
in the Bar, it is testing somewhere for mx.controls.Button, then I get
the nice cannot coeirce Tab to Button.
If there was an IButton interface or ITabButton interface that they
tested for, that would solve problems like this where I do not want to
subclass but to type an instance AS ITabButton interface that does what
the ITabButton interface requires..
Any thoughts? Am I doing something wrong when subclassing the Button?

Gordon,
I just made a composite tab button, re implemented a tab bar out of a NavBar, made it toggle and I am good for now.

Here's a quick example of a Button subclass which is only clickable on
its left side:
package {
import mx.controls.Button;
import flash.display.*;
public class ButtonTest extends Button {
override
protected function createChildren():void
{
super.createChildren();
var s:Sprite = new Sprite();
s.visible = false;
s.mouseEnabled = false;
addChild(s);
hitArea = s;
}
override
protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth,
unscaledHeight);
var g:Graphics = hitArea.graphics;
g.clear();
g.beginFill(1, 1);
g.drawRect(0, 0, unscaledWidth/2,
unscaledHeight);
}
}
}
Usage:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml xmlns=*
layout=absolute
ButtonTest label=I'm only active on the left side/
/mx:Application

Subject: [flexcoders] Flex2 :: Subclassing
Button :: How to
change hitarea placement
Hi,
I was wondering if anybody from
Adobe could shed some light on
how to go about adding like two little buttons to a Button?
I have tried with all my heart and
cannot find a way to chnge
the hitArea of a button to something smaller than it's bounds.
Are you just adding a click
listener to the whole component? If
so, this makes it really hard to subclass.
Can you give me any advice?
Peace, Mike
PS won't be asking these questions
when I can see the source !
:)
