Help, I'm clueless

[ngustavson emacinc com]

below is my original message describing my problem, I'm doing this for a touchscreen
so I really need bigger scrollbar buttons, anybody got any help for me




I am using an 2 Hscales packed into 1 Hbox , each scale is packed into a frame.
 I want to increase the height of the scale to make a blockier bar for scrolling,
but
 all attempts to do this with gtk_widget_set_usize on the box and scale fail to
 increase the height. What am I doing wrong?
