You might look at the code I wrote for nemiver's Breakpoints list where I do something similar. The code is at http://svn.gnome.org/svn/nemiver/trunk/src/persp/dbgperspective/nmv-breakpoints-view.cc. Most of the action is in on_breakpoints_view_button_press_signal(). The important things to note are that the signal is connected *before* the default handler (pass a 3rd parameter of 'false' to connect()), and that I return 'true' from the signal handler to prevent the default handler from running (which would result in all of the other rows becoming de-selected). -- jonner _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
