Ok, thanks ( ^ _ ^ ) . At the end I create a example that run fine:
import pygtk
pygtk.require('2.0')
import gtk
import gobject
import threading
import time
gobject.threads_init()
class Test(threading.Thread):
def __init__(self):
super(Test, self).__init__()
self.quit = False
self.counter = 0
self.toggle = False
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.connect("delete_event", self.delete_event)
self.window.connect("destroy", self.destroy)
self.window.set_border_width(10)
self.button = gtk.Button("Hello World")
self.button.connect("clicked", self.hello, None)
self.window.add(self.button)
self.button.show()
self.window.show()
def run(self):
while not self.quit:
gobject.idle_add(self.update_button)
self.button.emit("clicked")
time.sleep(1)
def update_button(self):
if self.toggle:
self.button.modify_bg(gtk.STATE_NORMAL,
gtk.gdk.Color(65535,0,0))
else:
self.button.modify_bg(gtk.STATE_NORMAL,
gtk.gdk.Color(0,65535,0))
self.toggle = not self.toggle
def destroy(self, widget, data=None):
gtk.main_quit()
def delete_event(self, widget, event, data=None):
print "delete event occurred"
return False
def main(self):
self.start()
gtk.main()
def hello(self, widget, data=None):
self.counter = self.counter + 1
print("Hello " + str(self.counter))
if __name__ == "__main__":
hello = Test()
hello.main()
