I took your PortalPanel class above and added it to the page using
RootLayoutPanel.get().add(Widget)
This is what it took to get your widgets sizing properly:
public void resetSplitters () {
// parent height
int ph = this.getParent().getOffsetHeight();
// parent width
int pw = this.getParent().getOffsetWidth();
slp_Outer.setWidgetSize(slp_North, ph/2);
slp_North.setWidgetSize(fp_West, pw/2);
}
I was able to call this from both onAttach and onResize.
Hope this helps!
