Hi!
I'm trying to write a custom widget using PyGTK and stumbled over a
strange issue: Clicking a drawingarea triggers leave_notify and
enter_notify (before button press and release can happen). That is, here
on Ubuntu with GTK+/PyGTK 2.12.0, but not on someone else's system with
2.12.5/2.12.1.
I've been told it's not an PyGTK issue.
Which one is the desired behaviour? I hope it's to not trigger leave by
clicking, as I need a way to check if the mouse cursor just moved onto
the widget or not.
My stripped down test code:
-----
#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk
from gtk import gdk
import gobject
# Create new widget, inherit from gtk.DrawingArea
class PopupScroller(gtk.DrawingArea):
def __init__(self):
super(PopupScroller, self).__init__()
# gtk.Widget signals
self.connect("enter_notify_event", self.enter_notify)
self.connect("leave_notify_event", self.leave_notify)
# unmask events
self.add_events(gtk.gdk.ENTER_NOTIFY_MASK | gtk.gdk.LEAVE_NOTIFY_MASK)
def enter_notify(self, widget, event):
print "enter"
#self.queue_draw()
def leave_notify(self, widget, event):
print "leave"
#self.queue_draw()
def main():
window = gtk.Window()
scroller = PopupScroller()
window.add(scroller)
scroller.set_size_request(100, 200)
# Connect
window.connect("destroy", gtk.main_quit)
#scroller.connect(signal, signal_cb)
window.show_all()
gtk.main()
if __name__ == "__main__":
main()
