Hello,
Somme days ago I posted over SO* because I'm having some problems
to render a drawing area placed over a scrolled window.
I'm starting to think that I may have found a bug and I'd like to have
someone else's option. The code seems to be no problem over pyGtk2,
but it seems to don't work over pygobject. (I'd really like to find a
solution for GTK 3.14)

pyGobject Code:
|from gi.repository import Gtk, Gdk
import cairo
class Test(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self)
sw=Gtk.ScrolledWindow()
vp=Gtk.Viewport()
box=Gtk.VBox()
vp.set_size_request(100,100)
for i in range(3):
da=Gtk.DrawingArea()
da.connect("draw", self.draw, [0.3, 0.4, 0.6], da)
da.set_size_request(100,100)
box.add(da)
sw.add(vp)
vp.add(box)
self.add(sw)
self.show_all()
def draw(self, widget, event, color, da):
cr = widget.get_property('window').cairo_create()
cr.rectangle(0, 0, 100, 100)
cr.set_source_rgb(color[0], color[1], color[2])
cr.fill()
main=Test()
Gtk.main()

pyGtk2 code:
|import gtk, cairo
class Test(gtk.Window):
def __init__(self):
gtk.Window.__init__(self)
sw=gtk.ScrolledWindow()
vp=gtk.Viewport()
box=gtk.VBox()
for i in range(3):
da=gtk.DrawingArea()
da.connect("expose-event", self.draw, [0.3, 0.4, 0.6], da)
box.add(da)
sw.add(vp)
vp.add(box)
self.add(sw)
self.show_all()
def draw(self, widget, event, color, da):
cr = widget.get_property('window').cairo_create()
cr.rectangle(0, 0, 100, 100)
cr.set_source_rgb(color[0], color[1], color[2])
cr.fill()
main=Test()
gtk.main()|
Thanks so much for the help!
