[PyQt] List Widgets, adjustable

[Matt Smith]

Okay, I've got two QListWidgets in a frame with an HBoxLayout.  I was
looking for some suggestions to make the width of the two widgets
adjust-able. 

Ideally I would like to be able to grab the space between the widgets
with the mouse and move it to adjust the way that the available space is
distrubuted, ie one gets larger and the other gets smaller.

thanks
