Here is a subclass I made to expose some functionality that might help
you
class ResizableDockLayoutPanel extends DockLayoutPanel
{
public ResizableDockLayoutPanel(Unit unit)
{
super(unit);
}
public double getWidgetSize(Widget widget)
{
return ((LayoutData) widget.getLayoutData()).size;
}
public void setWidgetSize(Widget widget, double size)
{
((LayoutData) widget.getLayoutData()).size = size;
}
@Override
public void insert(Widget widget, Direction direction, double
size,
Widget before)
{
super.insert(widget, direction, size, before);
}
}
