	I have an application that displays source code, and I want to
	also display line numbers in the left margin.  Under normal
	circumstances, this would be easy, but in our case, we don't want
	the user selecting the line number digits when s/he highlights a
	line by triple clicking with the mouse...

	So I have thought of two possible solutions, each of which have
	their own set of questions:

	1) Build a panel to the left of the source text display that scrolls
	   as the text display scrolls.  (or in a transparent window over
	   the text display)

		-How do I "attach" the two panes so that the line number
		 pane scrolls then the user scrolls the source display
		 pane?

		-How can I make a pane to display the line numbers without
		 borders, so that it will look like it is really inside
		 the source display pane?

		-Can I make a scrollable pane for the line numbers without
		 it having a scrollbar?

	2) Add the line number digits to the text display.

		-How do I keep users from highlighting the digits when they
		 triple click the select key on the mouse?  (thus highlighting
		 a whole line)  Can I set "selection margins?"
