As Gustavo pointed out, you cannot draw until the window is realized.
Here is some template code for drawing
#!/usr/bin/env python
# this is meant to be used as a template file to practice drawing commands
import pygtk
pygtk.require('2.0')
import gtk
from gtk import gdk
def draw(widget):
print 'draw'
gc = widget.window.new_gc()
widget.window.draw_rectangle( gc, 1, 100,100,100,100)
def configure_event(widget, event):
print 'config'
draw(widget)
return gtk.TRUE
def expose_event(widget, event):
print 'expose'
draw(widget)
return gtk.TRUE
def realize(widget):
print 'realize'
draw(widget)
return gtk.TRUE
win = gtk.Window()
win.set_size_request(640, 480)
win.show()
vbox = gtk.VBox()
vbox.show()
win.add(vbox)
da = gtk.DrawingArea()
da.connect('configure_event', configure_event)
da.connect('expose_event', configure_event)
da.connect('realize', realize)
da.show()
vbox.pack_start(da, gtk.TRUE, gtk.TRUE)
button = gtk.Button('Quit')
button.show()
vbox.pack_start(button, gtk.FALSE, gtk.FALSE)
button.connect('clicked', gtk.mainquit)
gtk.mainloop()
You will probably want to connect your function which grabs a frame
and displays it when called to the gtk idle handler or timer,
Also, do you need to go through PIL? Can you not do something like.
widget.window.draw_rgb_image(gc, 1, 1, WIDTH, HEIGHT,
gtk.gdk.RGB_DITHER_NONE, vid.getImage(0), stride)
