In many places, I get user input using a GtkEntry (well, Gtk::Entry, since I'm using Gtkmm). I'd like to validate the input and, if the input is invalid, set the background colour of the Entry to red and restore focus to the Entry, if needed. I can do this by connecting to the "changed" signal of the GtkEditable. This works just fine when I want to filter the user input (I just read the text in the Editable, strip out any unwanted bits and set it with the new text). However, I really only want to do the validation (and highlighting in red) when the user has finished typing, either when they focus out or press Enter. When I tried this validation in the "activate" signal, this didn't work: it activated the default widget, which was the OK button of the dialog. I couldn't prevent the dialog returning RESPONSE_OK, even when there was an error. How can I prevent this happening? Should returning false in the "focus-out-event" signal handler stop this?
