Get various configuration options of a QPix plug-in area
The QPix plug-in area is specified by areaRef. If areaRef is not a valid QPix plug-in area reference, qpx_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:
| qpx_ModifiableFlag | 2 | Modifiable area content |
| qpx_TabableFlag | 3 | Tabbable area |
| qpx_DisplayNaturalSizeFlag | 4 | Display natural size of hi-res images |
| qpx_HideHorzScrollFlag | 5 | Hide horizontal scrollbar |
| qpx_HideVertScrollFlag | 6 | Hide vertical scrollbar |
| qpx_ModifiableMask | 4 | Mask for modifiable area property |
| qpx_TabableMask | 8 | Mask for tabbable property |
| qpx_DisplayNaturalSizeMask | 16 | Mask for natural size property |
| qpx_HideHorzScrollMask | 32 | Mask for hiding horizontal scrollbar |
| qpx_HideVertScrollMask | 64 | Mask for hiding vertical scrollbar |
Example
// Toggle the display of natural size C_LONGINT($error) C_LONGINT($areaFlags) $error:=QPx_GetAreaFlags (gQPixArea;$areaFlags) If ($error=qpx_noErr) If ($areaFlags ?? qpx_DisplayNaturalSizeFlag) $areaFlags:=$areaFlags ?- qpx_DisplayNaturalSizeFlag Else $areaFlags:=$areaFlags ?+ qpx_DisplayNaturalSizeFlag End if $error:=QPx_SetAreaFlags (gQPixArea;$areaFlags) End if
