This works for widgets which have their own gtk.gdkWindows. It's
mentioned in the gtk docs that this isn't always the case, and several
widgets will return their parent's gtk.gdk.Window. You can check for
this using the get_has_window method.
One approach is to stuff the buttons inside an EventBox, since that
will definitely provide it's own gtk.gdk.Window - something along the
lines of:
def run_pygtk():
import gtk
def disable_cb(widget, eventbox):
widget.set_sensitive(False)
cursor = gtk.gdk.Cursor(gtk.gdk.WATCH)
eventbox.window.set_cursor(cursor)
win = gtk.Window()
win.resize(400, 400)
win.set_title("PyGTK example")
win.connect('delete-event', gtk.main_quit)
eventbox = gtk.EventBox()
b1 = gtk.Button('Disable me')
b1.connect('clicked', disable_cb, eventbox)
eventbox.add(b1)
b2 = gtk.Button('I do nothing')
box = gtk.VBox()
box.pack_start(eventbox, False, False, 0)
box.pack_start(b2, False, False, 0)
win.add(box)
win.show_all()
