This is just based on a quick scan of the code, but see what (if 
anything) happens if you make these changes:

First, remove the LAYOUT_FILL_X from the dialog box's constructor 
options. I don't guess it's hurting anything, but it's being ignored; a 
dialog box is a top-level window and thus doesn't have a parent 
container to stretch out in:

     super(parent, "Category Dialogue", DECOR_TITLE|DECOR_BORDER)

Next, change the layout hints for the contents frame so that it 
stretches in both the x and y directions:

     contents = FXHorizontalFrame.new(self,
         LAYOUT_FILL_X|LAYOUT_FILL_Y)

Similarly, change the layout hints on the tree list so that it stretches 
in both the x and y directions:

     @treeview[""].listStyle |=
         (TREELIST_SHOWS_LINES |
          TREELIST_SHOWS_BOXES |
          TREELIST_ROOT_BOXES|
          LAYOUT_FILL_X|LAYOUT_FILL_Y)

By telling these two widgets to (additionally) stretch to fill up the 
remaining space in the y-direction, you shouldn't see any wasted space, 
vertically speaking.

Now as for your comment about the right-hand side of contents being 
blank: is it drawn with a white background? If so, that is just the tree 
list stretching to fill in the x-direction. But it doesn't "stretch" the 
tree items, if that's what you're asking. In other words, the tree 
items' text is going to be drawn in whatever the current text font is 
for that tree list.

Hope this helps; please follow up if this doesn't cover it.
