Re: [pygtk] position in scrolled window
I'm not sure if there's a canonical answer to this. The way I've done
this is:
view = gtk.
scroller = gtk.ScrolledWindow()
scroller.add(view)
vadj = scroller.get_vadjustment()
vadj.connect('changed', lambda a, s=scroller: rescroll(a,s))
def rescroll(adj, scroll):
adj.set_value(adj.upper-adj.page_size)
scroll.set_vadjustment(adj)
That will always keep the scroller at the bottom; I also usually add a
check to see if the last position was at the bottom, so it only
autoscrolls if it was already all the way down - that way the user can
scroll back up and not be interrupted.

[pygtk] position in scrolled window
Hi, I have added a scrolled window to my application. I want it to display always the lowest part of the widget inside it (a gtk.textview). How can I achieve this?

Re: [pygtk] Draw rectangle with GDK
I would like know, if is it possble to use GDK with pygtk ?
If yes, then what is the syntax to use it ? example : how to draw
rectangle in window ?
Maybe this example will help you:
import pygtk
pygtk.require("2.0")
import gtk
def on_expose(da, event, *args):
gdkwin = da.window
gc = gdkwin.new_gc()
gc.foreground = gdkwin.get_colormap().alloc_color("blue")
gdkwin.draw_rectangle(gc, gtk.TRUE, 10, 10, 100, 100)
win = gtk.Window()
win.show()
win.connect("delete-event", gtk.mainquit)
da = gtk.DrawingArea()
da.show()
win.add(da)
da.connect("expose-event", on_expose)
gtk.mainloop()
When a window has to redraw itself, it emits the "expose-event".
You use the event handler to do draw into the window.
You could also use an offscreen drawable and copy the pixmap into the
window when necessary. You can force a window to redraw itself (emit
the "expose-event") by calling the window method queue_redraw().
Don't put complex drawing operations into the event handler because they
will be performed each time the window has to redraw parts.

[pygtk] draw on TextView borders
Hi to all, I would like to know if it's possible to draw somethings on TextView borders. According with testtext example it can be done with the C version of gtk but I can't undestand how to do it with pygtk. (with draw I mean the possibility to add small images or line numbers...) Has anyone already done this? How? Any tips or code example will be great Thank you!
