Configure various options of a QGrid area
The QGrid area is specified by areaRef. If areaRef is not a valid QPix plug-in area reference, qg_paramErr is returned.
Parameter areaFlags is a set of flags. Construct it by bitwise "OR" of any of the mask constants. Alternatively, you can set or clear individual bits of the areaFlags parameter using 4D's "Bit set" (?+) and "Bit clear" (?-) bitwise operators. Use the flag constants to address specific flags:
| qg_CellScroll | 21 | Scroll by whole cells |
| qg_TooltipsEnabled | 22 | Display tooltips with the cell caption text |
| qg_CellScrollMask | 0x00200000 | Mask for scrolling by whole cells |
| qg_TooltipsEnabledMask | 0x00400000 | Mask for displaying tooltips with the cell caption text |
Example
// Set the area to scroll by cell and display the caption in tooltips. C_LONGINT($err;$areaFlags) $areaFlags:=qg_CellScrollMask | qg_TooltipsEnabledMask $err:=QG_SetAreaFlags (xGrid;$areaFlags) ASSERT($err=qg_noErr)
