wxruby users - Nov 2005 - Wx::SystemSettings mark II

hi

patches and files for Wx::SystemSettings, with get_font included in swig 
file and a sample that doesn''t segfault wxruby.

CVS patches: RubyConstants.i, type_map.i
CVS new: system_settings.rb (sample) SystemSettings.i (SWIG file)

The sample should allow you to view the available information about 
system colours, fonts and metrics (eg cursor size, display size) in a Grid.

Incidentally, there seems to be a bug in Wx::Grid - when I double-click 
on a grid cell, I get

samples/system_settings/system_settings.rb:245:in `get_text_extent'': No
matching function for overloaded ''wxWindow_GetTextExtent''
(ArgumentError)
    from samples/system_settings/system_settings.rb:245:in `main_loop''
    from samples/system_settings/system_settings.rb:245

There''s no explicit call to get_text_extent, so maybe something getting
called by Wx that isn''t wrapped as expected?

cheers
alex

This is a known bug and I suppose once we all get back to working on 
wxRuby again we''ll tackle the last of these problems.

Very nice, thanks. It''s in. I put the sample in etc/

As Roy mentioned, we need to handle GetTextExtent specially. Hopefully 
we can just add a method to the %extend area in the .i file which calls 
the wx method, then packages the results into a ruby array to return. 
That''s how you can say x,y = some_function() right? We should probably 
match the Python approach and have two methods.
