wxruby users - Apr 2009 - FlexibleGrid column sizing

OK, I''m relatively new to wxruby, but have gotten a few forms
successful, and so building up some experience, but have run into a
major challenge with the following issue.  I want to generate a
table-like thing, that has a known number of columns, but a variable
number of rows, but the number of rows will be 25 or less; all the rows
are to be the same height, but the columns need to be all different
widths.

So I was using a FlexGridSizer, set the number of columns and rows; I am
able to put the sizer into a form and able to put controls into the
FlexGrid control without any proble.  However all the columns are the
same width, and I can''t find any combination of flags that will make
the
the columns anything other than the width of the widest column.  Most of
the controls going into the grid are TextCtrls and I have specified the
"maximum_size" attribute as a Size.new(x,-1) with the following flags:
ALIGN_LEFT  | ST_NO_AUTORESIZE.  When adding the controls to the
FlexGrid to "proportion" field is set to zero.  And yet all the
columns
are the same width, the width of the widest sub-control.

How can one specify a maximum column size?  How does one have a FlexGrid
recompute the column widths?  Is FlexGrid the wrong thing to do this
with?

You probably want to call FlexGridSizer#add_growable_col with a 
proportion > 0 on at least one column in the sizer. That column will 
then receive available additional space, and the other columns will have 
the minimum size for their controls.

If all proportions == 0, the available space is distributed evenly 
between all columns:
