[pygtk] mouse clicked signal is lost after widget reactivation

[Cristiano Otto Von Trompczynski]

Hi all,

I have tried to use the 'clicked' signal for catching keyboard and mouse 
events on button. But If I put my mouse pointer over the deactivated button 
and after that I check the checkbutton activating the button (by 
button.set_sensitive callback) but without removing the mouse pointer from 
button, when the button is reactivated I have to leave and 
enter into the button widget with mouse to catch the mouse 'clicked' signal 
again (see example below). This is a problem when users don't remove the 
mouse pointer from widget while reactivating button. It seems that mouse 
click doesn't work (if they don't move the mouse out and into the widget 
again). Does anybody know how could I workaround this problem?

example:
-------------------------------------------
#!/usr/bin/python
import gtk

window = gtk.Window()

hbox = gtk.HBox()
window.add(hbox)

button = gtk.Button("Click me")

def callback(button):
    print "clicked signal..."
button.connect("clicked", callback)

def callback(button):
    print "pressed signal..."
button.connect("pressed", callback)

button.set_sensitive(False)

checkbox = gtk.CheckButton("enable/disable BUTTON")
def toggled(checkbox):
    button.set_sensitive(checkbox.get_active())
checkbox.connect("toggled", toggled)
checkbox.grab_focus()

hbox.pack_start(checkbox, expand=True, fill=True)
hbox.pack_start(button, expand=True, fill=True)

def callback(win, data):
    gtk.main_quit()
    return True
window.connect("delete-event", callback)
checkbox.show()
button.show()
hbox.show()
window.show()

while gtk.events_pending():
    gtk.main_iteration()
gtk.main()
