Hello, everybody.
I have such problem: I'm creating a container and it's content at runtime. Here's a rough structure:
--VBox
----Form
-------FormItem
...
-------FormItem
----ControlBar
I have fixed maxHeights for the form
container to keep it in bounds of screen. But when I get vertical scrollbar, the horisontal also appears (seems like it's not enough place for this VScrollBar).
To escape this problem, I've created a listener for horisontal scroll appearing, so if it appears, I'll increase container a bit, so it would feet the other scrollbar normally:
form.addEventListener(Event.ADDED, function(event:Event):void{
if(event.target is HScrollBar){
while(form.horizontalScrollBar && form.horizontalScrollBar.visible && !(form.width > form.maxWidth)){
form.width += 10;
form.validateDisplayList();
}
}
});
I've tried also validateNow
and other similar methods. What I have here:
1. The HScrollBar
is being added.
2. We increase a bit the width of container, so it disappears.
3. When it disappears, the validating throws the null-pointer exception when it tries to measure the non-existing scrollbar. I've also tried to add validateProperties
before validation, but it didn't worked either.
Can anyone help to get rid of this annoying scroll? :)
