Hi Guys,

Cant use the search box because it seems to spit up and error. Basically I
want to fire a method for as long as a button is held down and stop as soon as
the button is released. I've written a method which I thought would do the
trick but it doesn't seem to work and I cannot see why.

Can anyone please tell me why the following gets stuck in an inifinite loop;

private function scrollDown():void{
trace("Mouse Down");
while(isMouseDown){
//calendarBox.verticalScrollPosition += 20;
trace("down");
if(isMouseDown == false){
break;
}
}
isMouseDown = true;
}

private function mouseUpDetect():void{
trace("Mouse Up");
isMouseDown = false;
}

<mx:Button x="128" y="517.9" label="v" mouseDown="scrollDown()"
mouseUp="mouseUpDetect()"/>

PushkinAS is correct, in your function mouseDownDetect you set isMouseDown = true so once in the while loop you will always be there, since it never gets reset to false. Good Luck.

You will want to use setInterval or Timer, to break up the loop. google this you will find some examples, here is one:
