There is no right answer ;-)
When the first Flash component framework was released, private variables had a
double underscore.
__width
__height
etc..
Basically because they usually replaced existing built-in properties, like
_width, _height, etc..
So what we ended up with was:
Built-in
_width
_height
Private
__width
__heigth
Public
width
height
Personally, I wouldn't use single underscores, because built-in properties use
them (in AS1 and AS2).
A component that needs its own sizing capabilities would then look something
like this:
class MyComponent extends MovieClip {
private var __width:Number;
private var __height:Number;
function MyComponent() {
__width = _width;
__height = _height;
// remove scaling that occured on stage
_xscale = _yscale = 100;
}
private funcion size():Void {
//use __width and __height for sizing..
}
public function setSize(w:Number, h:Number):Void {
__width = w;
__height = h;
size();
}
public function get width():Number {
return __width;
}
public function get height():Number {
return __height;
}
}
Might be some errors in the above code as I quickly wrote it down.
