implementing a right-click popup in a treeview

[Ferenc Gerlits <fgerlits gmail com>]

Hi,

I have a TreeView in which I would like to implement a right-click 
context menu.  For single selection, this is fine: I connect_notify() to 
the signal_button_press_event() signal, and find out which row the user 
wants from event->x and event->y.

However, I would like to have this for multiple selection, and I can't 
figure out how to do it.  The problem is that after my event handler, 
the standard event handler is called as well, which selects the row the 
user right-clicked on.  My event handler gets the correct selection that 
was before the right-click, and I can apply the action to that, so it 
works as expected, but to the user it looks wrong, because the selection 
shown on the screen is now different.

Is there any way to tell the Gtk engine not to call the standard event 
handler for right-clicks on this TreeView?  I think the normal way would 
be to return 'true' from my event handler, but connect_notify() expects 
a void method, so I can't do that.
