Re: [Flashcoders] Entering hex number (a color) as component parameter
As Johanness already mentioned, __hasInitialized is used to check if the
instance has initialized.
This is to avoid unnecessary method calls from the setter, as the setter is
called before the constructor.
Without the check, set bgColor would call SetBgColor before anything else.

Thank you and sorry - I've missed the Color type in Flash help.
But what is the role of __hasInitialized in your example? Why can't I just:
[Inspectable(defaultValue=#66,type=Color)]
public function get bgcolor():Number {
return __bgcolor;
}
public function set bgcolor(val:Number):Void {
__bgcolor = val;
invalidate();
}
(full source code in Bubble.* files @ http://preferans.de/flash/ )?

You might be better off using a getter/setter since you will have to redraw
the rect_mc each time the color changes.
private var rect_mc:MovieClip;
private var __bgColor:Number = 0x66;
private var __hasInitialized:Boolean = false;
private function draw() {
setBgColor();
__hasInitialized = true;
}
private function setBgColor():Void {
// draw stuff, using __bgColor
rect_mc.clear();
rect_mc.beginFill(__bgColor);
// etc..
rect_mc.endFill();
}
[Inspectable(defaultValue=#66,type=Color)]
public function get bgColor():Number {
return __bgColor;
}
public function set bgColor(val:Number):Void {
__bgColor = val;
if(__hasInitialized) setBgColor();
}

Re: [Flashcoders] Entering hex number (a color) as component parameter
Looks wrong to me because the drawing code (the setBgColor())
is called outside of the draw() method. Flash Help says to call
invalidate() from the set methods instead...

Re: [Flashcoders] Entering hex number (a color) as component parameter
listen to that! the v2 components are sheet in flash unfortunately when compared to flex 1.5. if however you are hell bent on using the v2 framework, invalidate will be the thing to use, i would (residual memory kicking in) still have your own init flag.

[Flashcoders] Entering hex number (a color) as component parameter
Hello flash coders,
I have a mostly working component (please see Bubble.*
in http://preferans.de/flash/ ), but wonder how to make
the background color to be a parameter. Currently I have:
class Bubble extends UIComponent
{
[Inspectable(defaultValue=0x66, type='Number')]
private var bgcolor:Number = 0x66;
private function draw():Void {
super.draw();
// draw a yellow rectangle: w x h
rect_mc.clear();
rect_mc.beginFill(bgcolor);
rect_mc.moveTo(0, 0);
rect_mc.lineTo(w, 0);
rect_mc.lineTo(w, h);
rect_mc.lineTo(0, h);
rect_mc.lineTo(0, 0);
rect_mc.endFill();
- but the component inspector (Alt-F7) won't allow me to enter
hexadecimal values like 0xFF into the bgcolor field. Only
decimal values will work (which is a bit awkward to use for colors).
How could I circumvent this? Use string?
Regards
Alex

Re: [Flashcoders] Entering hex number (a color) as component parameter
Try this:
[Inspectable(defaultValue=#66,type=Color)]
public var bgcolor:Number = 0x66;
You might be better off using a getter/setter since you will have to redraw the
rect_mc each time the color changes.
private var rect_mc:MovieClip;
private var __bgColor:Number = 0x66;
private var __hasInitialized:Boolean = false;
private function draw() {
setBgColor();
__hasInitialized = true;
}
private function setBgColor():Void {
// draw stuff, using __bgColor
rect_mc.clear();
rect_mc.beginFill(__bgColor);
// etc..
rect_mc.endFill();
}
[Inspectable(defaultValue=#66,type=Color)]
public function get bgColor():Number {
return __bgColor;
}
public function set bgColor(val:Number):Void {
__bgColor = val;
if(__hasInitialized) setBgColor();
}
