I'm using GTKMM 3.10.1 on 64-bit Ubuntu 14.04. I've
got three Gtk::MenuToolButtons in my UI, and I want the same icon
to appear on all three of them. This seems not to work -- my icon
appears only on the last button to be instantiated, and the first
two have no icon, only the activate arrow. To get my icon to
appear on all three buttons, I've had to fetch the icon as a
Gdk::Pixmap and create from it three unique Gtk::Image instances,
one for each button. Should I presume there's some arcane Gtk
requirement that makes this necessary? And, in a closely related but extremely minor issue, I've noticed that run-time error messages related to Gtk::Image problems in Gtk::Builder mis-identify the source, e.g. gtkmm-CRITICAL **: gtkmm: Gtk::Buidler: widget `FolderIcon' was not found in the GtkBuilder file, or the specified part of it. |
