Re: Detecting Ctrl Esc in GTK app

How would you link it directly to the window then rather than to a widget?

As far as I can see you need to associate it with a signal, but looking down the list of signals for windows I cant really see one suitable, hence I was using this:


Im using Ctrl Q for the time being as I havent worked out how to set it up for Esc yet.

The reason for doing this is Im writing an app for a public kiosk which will take over the whole screen and not provide any way for the user to exit the app. The admin will press Ctrl Esc (or Ctrl Q for the moment) which will pop up a dialog for a password to exit the app.

Hi Andrew,

You can add an accelerator to a window and it'll be called when that
key combination is pressed. It doesn't need to be associated with a

However I think it's generally considered good form to have a menu
item somewhere with the accelerator as a shortcut. That way the user
can discover your handy keypress and get some idea what it does.

Thanks for the tip.  Can accelerators only be used with menu items, only Ive
just tried doing it by linking it to the clicked signal on a (hidden)
GtkButton but it doesnt work?

My idea was when the key combo was pressed the accelerator would emit a
clicked signal on the button and the buttons handler would then be called.

That lets you detect ctrl-esc anywhere on the desktop. If you only
need to detect crtl-ecs within your window you can just set
"<Control>Escape" as an accelerator, see:

Is there a way to regiser a handler function which will be called
the user presses Ctrl-Esc in a GTK app?
