QPxObs_RedrawArea

QPxObs_RedrawArea(areaRef; redrawOpts):error
areaRef Longint QPix area reference
redrawOpts Longint Redraw options
error Longint Error result

Do not use this command in QPix v3 or later

This command is preserved in QPix v3 for backward compatibility reasons. There is no reason to force a plug-in area redraw in QPix v3 and later.


Forces a QPix plug-in area to be redrawn.

The QPix plug-in area is specified by areaRef. If areaRef is not a valid QPix plug-in area reference, qpx_paramErr is returned.

Passing qpx_UpdateBuffers in redrawOpts will also force update the area's offscreen buffer from the image source.

Note

Example

 
`Redraw area
 
C_LONGINT($error)
 
$error:=QPx_RedrawArea (gQPixArea)
 
If ($error#qpx_noErr)
   `Handle the error
End if
