Hello all you happy people!  
I am trying to learn wxruby and to that effect I played with the  
tutorial,  
which is very limited.  
I am trying to draw a grid for a sudoku puzzle. I first tried using  
GridSizer but then I did not know how to add each cell (button) to the  
9x9  
grid.  
Then I thought that perhaps I should use GridBagSizer for flexibility or  
something else.  
I need to be able to change the caption of the button, which could have  
a  
number from 1 to 9, dynamically.  
Which class should I use and where can I find examples of it uses?  
I searched Google with different search keys but could not really find  
any  
example.

Your help will be greatly appreciated.

Thank you

Questions about wxRuby are more appropriate to the wxruby-users mailing  
list:  
[http://rubyforge.org/mailman/listinfo/wxruby-users](http://rubyforge.org/mailman/listinfo/wxruby-users)  
OR WEB ACCESS:

If possible, show some example code with what you’ve tried and you will  
find people happy to advise.

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)

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.

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.
