Package: python-evince
Version: 2.28.0-5
I'm trying to write an application which makes use of both gstreamer
and python-evince - in order to get gstreamer to work properly, I need
to call gtk.gdk.threads_init() when importing modules.
This unexpectedly causes problems when using a evince.View widget in
presentation mode.
I have included below a short program which demonstrates the problem -
I can reproduce this bug in both my desktop and my laptop.
import gtk
gtk.gdk.threads_init() # commenting out this line makes the problem go away.
import evince
class EvinceWindow(gtk.Window):
def __init__(self):
super(EvinceWindow, self).__init__()
document = evince.factory_get_document(
'file:///home/flowblok/test.pdf',
)
view = evince.View()
view.set_document(document)
# view.set_screen_dpi(96)
# view.set_sizing_mode(evince.SIZING_BEST_FIT)
view.set_presentation(True)
scroll = gtk.ScrolledWindow()
scroll.add(view)
self.add(scroll)
if __name__ == '__main__':
win = EvinceWindow()
win.show_all()
win.connect('destroy', gtk.main_quit)
gtk.main()
