GtkTreeView menu popup

[tom <tom dbservice com>]

how can i add a popup menu to a treeview ?
so when the user presses the right mouse button, the menu appears ?

a second question:
can i add/remove widgets from my window ?
i want to do something similar like anjuta does: that you can detach 
windows from the main window and put them back again later
or simply hide a widget

thanks
tom
