Class: TEgFireGrid
property AutoColumnIndex: Integer default 0;The column that absorbs the width difference when AdjustColumnWidth
runs with AutoColumnAll
off: it grows when the grid gets wider than the columns and shrinks when
it gets narrower. The value is an index into VisibleColumns
(hidden columns are not counted), 0 being the leftmost.
When the user moves a column, AutoColumnIndex follows
it, so it keeps naming the same column.
If shrinking this column alone would make it narrower than MinColumnWidth,
every column shares the difference instead, for that adjustment only. A
value outside the range of the visible columns is accepted but turns the
adjustment off, even with AutoColumnAll, until it names a
visible column again.
