hello guys,
please, I need help. I am new to pygtk and python and in my .py file I am
getting error: gtkwarning: gdk_property_change: assertion 'window != NULL'
failed
this error occurs when I right click on textview and select cut/paste/copy.
What am I doing wrong? thank you in advance.
my xaa.py code looks like:
import sys
import traceback
import pygtk
pygtk.require("2.0")
import gtk
import gobject
class jednoduchy_textovy_prohlizec ():
def __init__(self):
self.okno = gtk.Window()
self.okno.set_title("Textový editor")
self.okno.set_border_width(10)
# Editor
self.textovy_buffer = gtk.TextBuffer()
self.textovy_prohlizec = gtk.TextView(self.textovy_buffer)
self.posuvnikove_okno = gtk.ScrolledWindow()
self.posuvnikove_okno.set_policy(gtk.POLICY_AUTOMATIC,
gtk.POLICY_AUTOMATIC)
self.posuvnikove_okno.add_with_viewport(self.textovy_prohlizec)
self.vbox = gtk.VBox(False, 5)
self.vbox.pack_end(self.posuvnikove_okno)
self.okno.add(self.vbox)
self.okno.show_all()
self.okno.connect("destroy", gtk.main_quit)
if __name__ == "__main__":
aplikace = jednoduchy_textovy_prohlizec()
gtk.main()
