[gtkmm] a few questions( screen-refreshing, colors, character-width )

[Bart Hakvoort <bart hakvoort castel nl>]

Working on my project i stumble across a few ( little ) problems.

1 - How can i update( refresh ) the screen? after eg. a thread changes
the content of a label, i first have to focus the widget before anything
wil happen.

2 - Is it possible to change the "backgroundcolor" from my application?
( and other widgets of course ) And yes, how is it performed?

3 - In my treeview some characters take more space then others. For
example, a 'w' takes twice the space of a 't'. This makes it very
difficult to align te text.
Is there a setting, so that every character wil take the same space?

so far for now, thanks in advance!
