I'm implementing a dialog which contains a list of symbols implemented
I've implemented the dialog as a subclass of GtkDialog and the
application runs it with gtk_dialog_run.
Now I want to intercepet if the user double-click on an elemente of the
list so that I can return the proper GTK_RESPONSE.
Looking at the docs it's not clear to me which event should I connect
to. Can someone give me a hint?
sorry to reply to myself, but re-reading my mail I see I've not been
I've connected my tree view to the button-press-event with:
/* when a symbol is double-clicked we emit a OK response */
g_signal_connect (G_OBJECT (GTK_WIDGET (dialog->list)), "button-press-event",
G_CALLBACK (gkd_on_double_click), dialog);
where the callback is:
gkd_on_double_click (GtkWidget *widget,
if (bevent && (bevent->type == GDK_2BUTTON_PRESS))
gtk_dialog_response (GTK_DIALOG (dialog), GTK_RESPONSE_OK);
The problem is that the above code gets all button-press-events and the
user cannot select another row of the list with the mouse...
"button-press-event" expects callback that returns gboolean value
(FALSE: continue signal emission, TRUE: stop it). Your callback has
'void' return type - so you'll get random result (in most cases: TRUE).
NOTE: *all signals* with names like "*event" expects *gboolean* return
value from callback.
