Configure the appearance 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 displayFormat specifies how the plug-in area displays its content. Set displayFormat to qpx_PictScrolling to configure the area as scrollable, or use any other constant to emulate 4D's picture display formats:
| qpx_PictScrolling | 0 | Picture has scrollbars |
| qpx_PictTruncCentered | 1 | Picture is truncated to the area rectangle size and centered in it |
| qpx_PictScaledToFit | 2 | Picture is scaled up or down separately across each dimension to fit the current area rectangle |
| qpx_PictTruncNonCenter | 4 | Picture is truncated to the area rectangle size and placed top left |
| qpx_PictScaledToFitProp | 5 | Picture is scaled down proportionally to fit the current area rectangle and placed top left |
| qpx_PictScaledToFitPropCenter | 6 | Picture is scaled down proportionally to fit the current area rectangle and centered |
Parameter frameStyle does nothing. The area's frame is no longer set using this parameter; use 4D's form editor to control the area object's frame.
Parameter focusRing specifies the style of the area focus ring. Use one of the following constants:
| qpx_NoFocus | 0 | No focus indication |
| qpx_SystemFocus | 1 | Focus indication using the system hilite color |
Example
// Set the plugin area to scrollable, no focus C_LONGINT($error) C_LONGINT($displayFormat;$focusStyle) $displayFormat:=qpx_PictScrolling $focusStyle:=qpx_NoFocus $error:=QPx_SetAreaStyle (gQPixArea;$displayFormat;0;$focusStyle)
