Thomas, But reality is a bit different, the layout panels are actively changing widget sizes, except the HeaderPanel. Additionally the forceLayout is a private method in this Layout widget, not that it matters to me in this case.
But Ok, I have a workaround in that I set the pixel size myself. I created a subclass of HeaderPanel that wraps the content widget in a custom panel that does a setPixelSize on the child when onResize is triggered. It would be nice if the HeaderPanel would have this behaviour ( or even support animation like the other Layout Panels do).
