Thanks, I have 3.22.5. I had tried `gtk-menu-popup-at-widget` but it
didn't work. I've tried lots of combinations to try and get it to work
without success.
Like this:
self.menu.popup_at_widget(self.anchor,Gdk.Gravity.SOUTH_WEST,Gdk.Gravity.NORTH_WEST,None)
I tried with self.menu being the first menu out of the uibuilder and
also with menu that I built manually (using Gtk.Menu, Gtk.MenuItem, etc)
and attached to the menubar. Both kinds of menu appear as expected and
work with the mouse just fine but they are different:
* The uimanager menu is <class 'gi.repository.Gtk.ImageMenuItem'>
* The manually built menu is <class 'gi.overrides.Gtk.Menu'>
This leads to different behaviour when I call popup_at_widget.
If I pull 'self.menu' out of UIManager then I get an error:
self.menu.popup_at_widget(self.anchor,
Gdk.Gravity.SOUTH_WEST,Gdk.Gravity.NORTH_WEST,None)
AttributeError: 'ImageMenuItem' object has no attribute
'popup_at_widget'
Whereas if I use the manually built menu I get warnings:
Gtk-WARNING **: no trigger event for menu popup
Warning: g_object_set_data: assertion 'G_IS_OBJECT (object)' failed
self.menu.popup_at_widget(self.anchor,Gdk.Gravity.SOUTH_WEST,
Gdk.Gravity.NORTH_WEST,None)
It makes no difference whether self.anchor is the box widget or the
menubar widget pulled from UI manager.
The menubar widget is <class 'gi.repository.Gtk.MenuBar'>
The box widget is box <class 'gi.overrides.Gtk.Box'>
> It's available for GTK+ 3.22 and up, so I cannot test it to verify.
My other thought is that popup_at_widget is only 3.22+. I wanted to find
a solution that worked in Gtk3 and Gtk2 because I am evaluating both of
them (there are things I need that can't be done using Gtk3 without
falling back on Xlib).
So perhaps the above isn't the way, and there is another way to achieve
this...
I appreciate any help.
John
