Get the user selection options for a QGrid area
Parameter areaRef is the QGrid area reference. If areaRef is not a valid QGrid area reference, qg_paramErr error is returned.
Parameter selectionFlags receives the user selection options. QGrid defines the following constants for selectionFlags:
| qg_SelectionNotAllowed | 1 | No user selection is allowed |
| qg_SelectOneCell | 2 | Only single cell selection is allowed (default) |
| qg_SelectManyCells | 6 | Multiple cell selection is allowed |
Parameter frameColor receives the color used for highlighting (framing) the user-selected cells, expressed in 4D's RGB color notation (0x00RRGGBB - see OBJECT SET RGB COLORS in 4D's documentation).
Parameter frameWidth receives the frame width in pixels.
Example
// Change the area to single-cell selection mode. C_LONGINT($err) C_LONGINT($selectionFlags;$frameColor;$frameThicknes) $err:=QG_GetSelectionOptions (xGrid;$selectionFlags;$frameColor;$frameThicknes) ASSERT($err=qg_noErr) $err:=QG_SetSelectionOptions (xGrid;qg_SelectOneCell;$frameColor;$frameThicknes) ASSERT($err=qg_noErr)
