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 |
