Configure the visibility of the parts of a scrollable 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 areaParts specifies which parts of the plug-in area will be visible or not. It is a set of flags that can be constructed by combining with bitwise "OR" any of the mask constants. Alternatively, set or clear individual bits of the areaParts parameter using 4D's "Bit set" (?+) and "Bit clear" (?-) bitwise operators. Use the part constants to address specific parts:
| qpx_MenubarPart | 1 | Area menubar part |
| qpx_ToolsWidgetPart | 2 | Tools widget part |
| qpx_ZoomWidgetPart | 3 | Zoom widget part |
| qpx_MenubarMask | 2 | Mask for area menubar part |
| qpx_ToolsWidgetMask | 4 | Mask for tools widget part |
| qpx_ZoomWidgetMask | 8 | Mask for zoom widget part |
| qpx_PageNavWidgetPart | 4 | Page navigation widget part |
| qpx_PageNavWidgetPartMask | 16 | Mask for page navigation widget part |
Example
// Display menubar, tools, and zoom widget C_LONGINT($error) C_LONGINT($areaParts) $areaParts:=qpx_MenubarMask | qpx_ToolsWidgetMask | qpx_ZoomWidgetMask $error:=QPx_SetAreaParts (gQPixArea;$areaParts)
