Understanding accelerators.
Hi, I'm trying to understand the difference between accelerators and the “key-press-event” signal. Let's say I have a window with just one button quit. I'd like to handle the controloq key event to quit the application. I now I can connect to the top window key-press-event, but - just to understand how things work - is there any way to do the same with accelerators? Or are accelerators exclusively intended to be used with menus? I'm totally lost in the documentation bouncing between actions, accelerators, accerator groups, action groups, ui managers, etc, and I can't find a SIMPLE example. Any help would be greatly appreciated.

You do not attach to any key-press signal. Attach to the button clicked signal. GTK provides the functionality to capture the keyboard press and route it to the button click. You're complicating this a little. It's not that complicated. :) ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Understanding accelerators.
Mnemonics are discouraged by the HIG, and AFAIK they are not displayed by recent GTK versions. From the user's perspective, I think there is no difference. However, if you are using GApplication/GtkApplication, it is easier to register accels, and you can even make them easily customizable for the users. I'm yet to find a good example on the Interwebs, but if you take a look at GNOME 3.14 apps, you will find some for sure.

Re: Understanding accelerators.
This is becoming offtopic, but… this is strange, last time I saw a discussion about them, they were considered out of date or something and many was upset that they are gone (even if only at theme level). Sorry then, it's my mistake.
