Get various options of a QGrid area
The QGrid plug-in area is specified by areaRef. If areaRef is not a valid QPix plug-in area reference, qg_paramErr is returned.
Parameter areaFlags receives a set of flags. The received value can be tested for specific options by bitwise "AND" of any of the mask constants. Alternatively, you can test individual bits of the areaFlags parameter using 4D's "Bit test" (??) bitwise operator. 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
// Toggle the display of caption text in tooltips. C_LONGINT($err;$areaFlags) $err:=QG_GetAreaFlags (xGrid;$areaFlags) ASSERT($err=qg_noErr) If ($areaFlags ?? qg_TooltipsEnabled) $areaFlags:=$areaFlags ?- qg_TooltipsEnabled Else $areaFlags:=$areaFlags ?+ qg_TooltipsEnabled End if $err:=QG_SetAreaFlags (xGrid;$areaFlags) ASSERT($err=qg_noErr)
