In the aim of customizing workbench content, I have to override
ceateWindowContents method of ApplicationWorkbenchWindowAdvisor class of
my RCP application. I add supplementary graphic controls before main
Coolbar area. I add my content and then I call the
super.createWindowContent(shell). The problem is that my graphic controls
are displayed in front of main toolbar and hide a part of it. Do somebody
know how to fix this problem ?
