// match stage dimensions;
$disp.width = _stage.stageWidth;
$disp.height = _stage.stageHeight;

if (_registeredObjects[$disp].fitStageHeight == true && _registeredObjects[$disp].fitStageWidth == true)
break;

// adjust proportionally to fill stage width or height;
if (_registeredObjects[$disp].fitStageHeight == true)
$disp.scaleX = $disp.scaleY
if (_registeredObjects[$disp].fitStageWidth == true)
$disp.scaleY = $disp.scaleX
else
( $disp.scaleX > $disp.scaleY ) ? $disp.scaleY = $disp.scaleX : $disp.scaleX = $disp.scaleY;

i want to implement also minWidth and minHeight and change the way the arguments are passed to be something more friendly like a tween call where i can pass args in no specfic order… instead of just true or false

case TR:
if (_registeredObjects[disp].stayRelative){
// original code uses _stageW so it relies on original window size
//disp.x = sw – _stageW + _registeredObjects[disp].ogX;

// new code
// figures out how far from the right of the page the item should be
// depending on the minimum stage width assigned and subtracts that
// from the current stage width each time stage is resized
disp.x = sw – (_minW – _registeredObjects[disp].ogX);
//y doesn’t change
}else{
disp.x = (sw – disp.width);
disp.y = 0;
}
break;

I didnt mess with the code in the else statement because I’m not using that in my application. Thanks a lot for this class guys. I’ve always been a sucker for liquid layout. hence my company name = fluid web design

I cleaned up the packaging of the class for you. You should follow packages standards so that other people can store this with their other class.

There are a few things still wrong with it though.

1: stayRelative set to true breaks the class.

2: stayRelative set to true should be default since people would expect that the local x/y of the object would be where it positioned..

3: I added a throw error on the constrictor so that you can’t create an instance and understand why.

4: I added some basic docs: used asdoc with flash develop

5: I added a flash develop project. Way better then flash IDE and comparable to flash builder

6: you could probably dispatch an event when StageAlignTool is set on or off and or if you reached min x/y

7: you could use Event.ADDED_TO_STAGE and Event.REMOVED_FROM_STAGE to listen for when the DisplayOject is added to stage to start the init() or registerLocation(), or to call kill when the item have been remove from the stage. that way you have to call one less function.

Any how, nice work.

package {
import StageAlignTool;

public class Main extends MovieClip {

var object:MovieClipInstance = new MovieClipInstance();

public function Main() {
addEventListner(Event.ADDED_TO_STAGE, initMain);
}

private function initMain(event:Event) {
StageAlignTool.init(stage, 1024, 768);
StageAlignTool.registerLocation(object, StageAlignTool.TL);
}
}
}
