[news.eclipse.tools.gef] Re: draw2d.text indent strategy

["Randy Hudson" <none@xxxxxxxxxx>]

(It's great when someone posts a question and has looked at the code!)

Do you want a border/margin around a TextFlow or some other InlineFlow?  We
would like to support inline borders maybe in the 3.1 release.  Or, do you
want to process TAB characters and advance the LineBox's current X position
to the next "tab stop"?

If you just want a nested block with a border, you should be able to handle
this at the BlockFigure or its layout.  Perhaps in setupBlock, the
recommended width should substract insets.getWidth()
