Column number for the first visible column.

Description

GetFirstVisibleColumn is an Integer function used to get the column number for the first visible non-fixed column in the grid. A visible column is one which starts after the fixed columns specified in FixedCols and has a non-zero width for the column in ColWidths.

The return value contains the column number (zero-based) for the column matching the criteria. If a non-fixed column with a non-zero width is not found, the return value is set to ColCount.

GetFirstVisibleColumn is called from the KeyDown method when handling Tab key navigation for the grid control.
