it can probably be a lot simpler than that even...

we have a themed QToolButton in libplasmagenericshell called ToolButton. we 
can (and do) use those as regular ol' QWidgets.

then there is PanelView in desktop/shell/panelview.h which is a QWidget as 
well, and the PanelView class does the hide/show management.

so when it is set to manual hiding, PanelView could create a ToolButton and 
place it as a child QWidget. it could set a contents margin on itself to make 
room for it, and then the containment will naturally be adjusted to fit that. 
some of the calculations for things like "maximize panel" may require some 
adjustments as a result, unless they are already based on contentsRect() 
rather than just size().

so in this case it's really just typical QWidget based development and there 
isn't really any special Plasma / QGraphicsView voodoo needed :)
