Description

SelectCell is an overridden Boolean function used to determine whether the cell specified in ACol and ARow can be selected in the grid control. It is used to respond to focus changes for the control.

SelectCell calls the inherited method on entry to get the return value for the method. The return value is True when both ColWidths and RowHeights have positive non-zero values for the column and row numbers where the cell is located.

SelectCell signals the OnSelectCell event handler (when assigned). The event handler can be used to override the return value based on the column and / or row number.

SelectCell is used in the implementation of methods like TryMoveSelection, CheckPosition, SelectEditor, and GetDeltaMoveNext.
