S�l !
I tried my example but without any sucess as the area is not suppose to have that
method !
Traceback (most recent call last):
File "./ldraw2.py", line 2884, in area_expose_cb
area.window.signal_handler_block(self.signal_id)
AttributeError: 'gtk.gdk.Window' object has no attribute 'signal_handler_block'
I even tried with the window from area
Traceback (most recent call last):
File "./ldraw2.py", line 2884, in area_expose_cb
area.window.signal_handler_block(self.signal_id)
AttributeError: 'gtk.gdk.Window' object has no attribute 'signal_handler_block'
What has the signal_handler_block method ?
Any other idea on the way to proceed ?
Takk
