This is a demonstration of how to do \
a toolbar that is styled correctly \
and which can be torn off (this feature reqrires Tcl/Tk8.5). \
The buttons are configured to be \\u201Ctoolbar style\\u201D buttons by \
telling them that they are to use the Toolbutton style. At the left \
end of the toolbar is a simple marker that the cursor changes to a \
movement icon over; drag that away from the toolbar to tear off the \
whole toolbar into a separate toplevel widget. When the dragged-off \
toolbar is no longer needed, just close it like any normal toplevel \
and it will reattach to the window it was torn off from.
