I’ve recently been attempting to port an application written using a
different GUI toolkit to gtk2. The application makes use of several
displays that present data in a table format, like a spreadsheet. I
gather that the canonical way of doing this using ruby/gtk is via a
TreeView+ListStore combo, and I have implemented it this way, Some
columns contain monetary amounts, and for these the data should be
presented right-justified, but after extensive googling I have been
unable to figure out how to do this. Please, give advice!
