Hi all,
I'm having trouble writing a simple image viewer using PyGtk and Imlib. I
can load the first image fine, but I don't know how to display the second
image into the first pixmap without creating and showing a completely new
Pixmap widget for it (thus causing terrible flicker as the widget is erased
and redrawn). From reading the source, I see that the GtkPixmap.set()
method might be what I want, but I can't get it to work.
Here's what I'm trying:
def next(window, event):
img2 = GdkImlib.Image('page02.gif')
img2.render()
pix2 = img2.make_pixmap()
pix = window.get_data('user_data')
pix.set(pix2, None)
def main():
window = gtk.GtkWindow()
window.connect('key_press_event', next)
img = GdkImlib.Image('page01.gif')
img.render()
pix = img.make_pixmap()
window.set_data('user_data', pix)
window.add(pix)
pix.show()
window.show()
gtk.mainloop()
And this is the error I get:
Traceback (innermost last):
File "/usr/lib/python1.5/site-packages/gtk.py", line 125, in __call__
ret = apply(self.func, a)
File "../test.py", line 11, in next
pix.set(pix2, None)
File "/usr/lib/python1.5/site-packages/gtk.py", line 2225, in set
_gtk.gtk_pixmap_set(self._o, pixmap, mask)
TypeError: gtk_pixmap_set, argument 2: expected GdkWindow, instance found
Obviously I'm trying to use pix.set() incorrectly. What's the right way?
