Figuring out the correct height / width of scrollbars under Linux

[Malte Brill]

First of all… Thanks to all who replied.

@Warren: I need this for a custom control that has seperate scrollbars that are not tied to the group. I need to adjust those scrollbars to fit to the right /v bottom of that group. Dragging out a standard scrollbar was far too wide and left about 5 pixels space on the bottom / the right of the group, where contents shines through the non opaque area of the scrollbar and leaves the control looking very unprofessional (and ugly).

Best,

Malte
