Hello,
I have a probably very stupid problem:
I'm trying to create a custom v2 component representing
a playing card (full source code at the bottom). It works
mostly ok, but when I try to get _parent's _width and
_height in its onPress handler in order to restrict dragging:
private function onPress():Void {
setDepthTo(DepthManager.kTop);
startDrag(this);
// startDrag(this, false,
// 0, 0, _parent._width - _width, _parent._height -
_height);
dispatchEvent(clicked_obj);
}
I surprisingly get same values as for the _width and
_height of the component itself. And for _root too:
CLICKED CARD: [EMAIL PROTECTED],127.5 rot: 0
PARENT1: _level0 159.75x244.85
ROOT: _level0 159.75x244.85
PARENT2: 183.5x265.65
Why does it happen?
Thank you
Alex

short except the CARDS[] array):
