Questions about wxRuby are more appropriate to the wxruby-users mailing list: http://rubyforge.org/mailman/listinfo/wxruby-users OR WEB ACCESS: http://www.ruby-forum.com/forum/36 If possible, show some example code with what you've tried and you will find people happy to advise. > I am trying to draw a grid for a sudoku puzzle.

You create and add a button to a sizer with something like this: sizer = Wx::GridSizer.new(9) # 9 column button = Wx::Button.new(parent, :label => '3') sizer.add(sudoku_button) > Then I thought that perhaps I should use GridBagSizer for flexibility or > something else. Probably not GridBagSizer. It's offered b/c it's part of the wxWidgets API, but there are almost always easier and simpler ways of doing the same thing, IMHO. > I need to be able to change the caption of the button, which could have a > number from 1 to 9, dynamically. No problem: button.label = "4" > Which class should I use and where can I find examples of it uses? You could use GridSizer + Buttons, as you have been. Simple, but it might look a bit strange. You could use Wx::Grid, a spreadsheet-style widget. A bit more work, but probably the most attractive solution: you could draw your own grid lines and numbers using a DC (Device Context). You will find examples of using all of these by looking in the samples distributed with the wxRuby gem / source. Look in samples/grid, samples/bigdemo/wxSizer and samples/drawing for help. a
