I thought it wouldn't matter if I define the range ...
But indeed, with larger values, adj.set_value() does have an effect.
In the version where placed the textview in a scrolledwindow, adj.upper
returns 204.0. But any value I set below to including 204.0 only scrolls
the view a few line, it doesn't even come close to the end.
What I also don't get at all: adj.page_size gives me 0.0.
I'm trying to do this in main, to get the basic concept of scrolling a
textview, before seeing how I can connect my special scrollbar:
def main():
window = gtk.Window()
hbox = gtk.HBox(homogeneous=False, spacing=0)
textview = gtk.TextView()
textview.set_editable(False)
textfile = open("demo_popup_scrollbar_20.py", "r")
buffer = textview.get_buffer()
buffer.set_text(textfile.read())
view = gtk.ScrolledWindow(None, None)
view.set_policy(gtk.POLICY_NEVER, gtk.POLICY_NEVER)
view.set_shadow_type(gtk.SHADOW_NONE)
view.add(textview)
scroller = PopupScroller()
# Layout
window.add(hbox)
hbox.pack_start(view, True, True)
hbox.pack_start(scroller, False, False)
scroller.set_size_request(16, 200)
view.set_size_request(400, 200)
#window.resize(200, 300)
adj = view.get_vadjustment()
# value, lower, upper, step_incr, page_incr, page_size
print adj.value
print adj.lower
print adj.upper
print adj.step_increment
print adj.page_increment
print adj.page_size
view.set_vadjustment(adj)
adj.set_value(180.0)
print adj.value
# Connect
window.connect("destroy", gtk.main_quit)
window.realize()
window.show_all()
gtk.main()
Thanks!
