/**
* A Toolbar shell is a widget floating around over the Main Window.
* It typically contains an undocked tool bar.  The Toolbar shell can
* be resized horizontally by grabbing its sides if the widget contained
* in the Toolbar shell has the LAYOUT_FIX_WIDTH option.  Likewise, it
* can be resized vertically if the LAYOUT_FIX_HEIGHT option is passed
* to the widget contained in the Toolbar shell.  If both LAYOUT_FIX_WIDTH
* and LAYOUT_FIX_HEIGHT are passed to the contained widget, Toolbar shell
* can also be resized by grabbing the corners.
* Normally, the Toolbar shell tries to accomodate changes in its contained
* widget by shrink-wrapping around it, i.e. if the contained widget changes,
* the Toolbar shell will change to fit narrowly around it.
