I was asked by pymaemo to post here as this appears to be a GTK bug on the N800 and not a pygtk 
bug.


Initial Comment:
# Dump this into the python 2.5 interpreter on the N800 and watch the fun.
# Also try resizing the bar and watch it ooze into position.
# What is going on here?  Someone please tell me what I'm 
# doing wrong.  It's not like this is a lot of text or anything.
# The choice of text below is just cut-and-paste nonsense,
# put something else there if you like.

import pygtk
import gtk
import hildon

text = """A horizontal or vertical sliding widget which permits the user to choose from a set of 
numerical or other values.  You can specify the precision of the number being displayed (note that, 
unlike gtk.Scale, this does not affect the user's settable choices).  You can add a label in one of three 
ways: first, you may provide a Label directly, which Slider will update for you.  Second, you can override 
the didChangeValue method to update a Label (or other widget) as you like when the slider is modified; 
you can call provideFormat to give you a formatted String given the current value.  Third, you can tell 
the Slider to provide a topLabel which floats with the widget (this is equivalent to gtk.POS_TOP).  This 
only really makes sense for horizontal sliders.  Last, you can specify if the slider is enabled or not.

The widget has three basic modes: first, it can slide smoothly among floating-point values from a 
minimum to a maximum; second, it can move by increments between a minimum and a maximum 
(known as 'ticks'); third, it can slide from choice to choice in a provided list.  For the first case, set 
minValue and maxValue to your desired values (defaults are 0 and 1).  For the second choice, set 
minValue and maxValue to your desired values, and set the number of ticks.  For example, if you wish 
to go from 0 to 10, inclusive, by increments of 2, that's 6 ticks.  For the third choice, minimum and 
maximum values are set for you (to 0 and length(list)-1).  The elements in the list are displayed to the 
user, and you determine programmatically which one is chosen by the index of the item.  You may also 
override the provideFormat(...) method, if you feel so inclined, to further customize display of 
information -- perhaps to create a logarithmic scale.

PERSISTENCE:  Slider takes a unique name, which it uses to store its numerical position in the 
application's persistence database.

HOOKS:
    didChangeValue(self, value):     The user has just changed the slider's value.
    provideFormat(self, value):      The slider needs a textual representation of the provided value.  
Return a String.  There is a default version of this method which handles most cases, so you needn't 
override this unless you feel so inclined.

GTK IMPLEMENTATION: Slider is implemented with either an gtk.HScale or a gtk.VScale."""


# Okay, here we go...
tv = gtk.TextView()
tv.set_wrap_mode(gtk.WRAP_WORD)
tv.get_buffer().set_text(text)
sc = gtk.ScrolledWindow()
sc.add_with_viewport(tv)
sc.set_policy(gtk.POLICY_NEVER, gtk.POLICY_AUTOMATIC)
sc.get_vadjustment().set_value(0)
sl = gtk.HPaned()
sl.add1(sc)
sl.add2(gtk.TextView())
w = hildon.Window()
w.add(sl)
w.show_all()
gtk.main()
