fxruby users - May 2007 - a table column that fills horizontally

Is there a way to specify that a table column should resize itself to 
fill available space, so that it is just big enough that there is no 
unused space in the table, but there is no horizontal scroll bar?

That might be too special a situation for FXTable in general to handle, 
but anyway here''s a way to do it (tested a little). The +fill+ variable
is the column number of the column that should adjust its width.

         fill_resizer = proc do
           other_width = table.verticalScrollBar.width +
             table.rowHeaderWidth +
             (0...columns.size).inject(0){|sum,c| sum +
               (c == fill ? 0 : table.getColumnWidth(c))}
           table.setColumnWidth fill, table.width - other_width - 1
           false
         end
         table.connect(SEL_CONFIGURE, &fill_resizer)
         table.columnHeader.connect(SEL_CHANGED, &fill_resizer)

No, nothing like that built in.

This is a slight improvement that is sensitive to whether the scroll bar 
is shown:

         fill_resizer = proc do
           other_width = table.rowHeaderWidth +
             (0...columns.size).inject(0){|sum,c| sum +
               (c == fill ? 0 : table.getColumnWidth(c))}
           vsb = table.verticalScrollBar
           other_width += vsb.width if vsb.shown?
           table.setColumnWidth fill, table.width - other_width - 1
           false
         end
         table.connect(SEL_CONFIGURE, &fill_resizer)
         table.columnHeader.connect(SEL_CHANGED, &fill_resizer)
