Hi Stefan, this question also came up a few years ago, where i detailed the solution i have employed for this problem here: https://mail.gnome.org/archives/gtk-list/2010-September/msg00047.html
i subsequently formalized this into a self-contained library, with a complete description of it here: http://www.binpress.com/app/gtk-widget-state-manager/1008 and, feel free to find the complete source code for free download here: https://gitlab.com/ivor/GTK-WSM do with it what you will, richard On Sat, Sep 19, 2015 at 11:07 PM, Tristan van Berkom < tris...@upstairslabs.com> wrote: > > > > On Sep 20, 2015, at 8:05 AM, Stefan Salewski <m...@ssalewski.de> wrote: > > > > OK, gtk_widget_set_sensitive () will do it. > > > > But I wonder how to do it for menu items that change sensitively often, > > for example COPY menu item.
