When I call textArea.setSize(w,h) in my ResizableFrame's layout function it get's stuck in a layout loop:
Only thing I find odd is that I don't see a TextArea in the stack???

Code:
WARNING: layout loop detected - printing

I have used a TextArea in another ResizableFrame as well, but don't have a layout function there (yeah I should do it, but it was one of the the first things I tried after finding TWL). The other TextArea's don't give the layout loop though and when I remove the setSize of the textArea the layout loop is gone.

I also tried using setMinSize and setMaxSize in the layout function, but it doesn't seem to obey to that.

Code:
lore.setMinSize(0, 0);
lore.setMaxSize(192, 90);
System.out.println(lore.getWidth() + " " + lore.getHeight() + " " + lore.getMinWidth() + " " + lore.getMinHeight());


This prints:
Code:
111 35 192 90          <- First time layout function is called, rest are all 519 377 0 0
519 377 0 0
519 377 0 0

By default ResizableFrame's layout() method calls layoutChildFullInnerArea() for each children, so you don't really need to override the layout method if this is what you want.

But with the amount of information you posted I can't help you at all.

Make sure that you only call setSize/setPosition of Widgets which are direct children.
You can try to debug that by setting a break point on childInvalidateLayout() to see from where it is invoked.

One thing to check is the getPreferredHeight() on the TextArea, currently TextArea calls invalidateLayout() when it's required height doesn't match it's actual size. The reason for this is that the height depends on it's width (flow text). Normally this is not an issue when it's placed inside a ScrollPane.
