The fixed_width attribute takes a boolean value (true or false),
with default value false. It has different meaning on a dialog, as
opposed to other tiles.
In a dialog, if fixed_width is false, the entire dcl dialog
gets horizontally resizable. This is a BricsCAD only feature, but
it won't disturb usage of the DCL dialog in other CAD
applications.
In any other tile, the fixed_width attribute influences
distribution of extra width during layouting of the dialog. If
fixed_width is true, the tile will not receive any extra width, so
it will occupy its minimum width only. If fixed_width is false,
then the tile will receive extra width during layouting - that is,
if extra width is available. This attribute is typically useful if
multiple tiles appear in the same row, to control which tiles in
the row can make more use of additional width.
Note: if a vertical alignment of a column and sibling child tiles with a
uniform space distribution is desired, it is required to enable the
fixed_width attribute for the column tile. Otherwise, the column
occupies more space.
