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()

Thank you David for your response. I am just a Gtk newbie so this question
is a tough one for me. Sorry for cross-posting & I won't do it again next
time. Thank you and have a good day.
