Re: Disabling accelerators when typing text

["Andrew E. Makeev" <andrew solvo ru>]

Actually, we are coding in GTKMM-2.4, but I will tell you what we did.

We have map of accelerator data: { Name }={ Action, Key, Modifier }
We have some MODE enumerator that could say which accelerators should be
active.

So, you need some activatable widgets (toolbarItem, menuItem, button,
etc), to use methods:

for( each entry in map )
{
  gtk_widget_add_accelerator() - when current MODE allow entry.KEY
  gtk_widget_remove_accelerator() - when current MODE disallow entry.KEY
}

https://developer.gnome.org/gtk3/stable/GtkWidget.html#gtk-widget-add-accelerator

So, you could add signal on FOCUS_IN to remove accelerators, and signal
on FOCUS_OUT to add accelerators.
