maximize with a specific style

Hi,

I'm using the same toolbar for two differents editors (sharedSpaces), the both editors have a transparent background.

When I activate the Maximize buton, the editors area is over the toolbar, so we can't use the toolbar.

Is-it possible to défine a spécific background (white) when the editor is activate, and define a "top padding" (or a top margin) to place the maximized editor bellow the toolbar ?

Thanks in advance
