GtkHScale: Jump-to-position by left-click instead of middle-click?
Hello everybody, I am new to GTK. I am trying to develop a small music player using GTK GStreamer. I use GtkHScale for the progress bar, which is responsible for updating the track progress allow user to move to different time position in the track. Everything works fine until now, except that I can not use left-click button to snap (or jump) to random position in the GtkHScale. Instead, I have to either drag or right-mouse-click. I have tried to solve this problem for several days and still can not figure out how to use left-click to jump to different position in the GtkHScale. I have searched through the GTK+ mail archive reference but found no place talking about this. Does anybody here know how to implement this functionality for GtkHScale? If so I hope you can give me a hint. Thank you and have a good day! -- Phong V.

Was it really necessary to cross-post this question to *four* mailing lists?

The following is a kluge, but I suppose if you want the first button to invoke the same response as the middle button it should be all right (written in Python for brevity): from gi.repository import Gtk def button1to2(scale, event): if event.button == 1: event.button = 2 return False adj = Gtk.Adjustment.new(0.0, 0.0, 1.0, 0.001, 0.01, 0) scale = Gtk.Scale.new(Gtk.Orientation.HORIZONTAL, adj) scale.set_round_digits(3) scale.connect(button-press-event, button1to2) scale.connect(button-release-event, button1to2) window = Gtk.Window() window.add(scale) window.set_default_size(400, -1) window.show_all() window.connect(destroy, Gtk.main_quit) Gtk.main() Yeti ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
