VIEWSTATUS enumeration (ocidl.h)

  • Článek

Specifies the opacity of the object and the drawing aspects supported by the object.

Syntax

typedef enum tagVIEWSTATUS {
  VIEWSTATUS_OPAQUE = 1,
  VIEWSTATUS_SOLIDBKGND = 2,
  VIEWSTATUS_DVASPECTOPAQUE = 4,
  VIEWSTATUS_DVASPECTTRANSPARENT = 8,
  VIEWSTATUS_SURFACE = 16,
  VIEWSTATUS_3DSURFACE = 32
} VIEWSTATUS;

Constants

 
VIEWSTATUS_OPAQUE
Value: 1
The object is completely opaque. So, for any aspect, it promises to draw the entire rectangle passed to the IViewObject::Draw method. If this value is not set, the object contains transparent parts. If it also support DVASPECT_TRANSPARENT, then this aspect may be used to draw the transparent parts only.

This bit applies only to CONTENT related aspects and not to DVASPECT_ICON or DVASPECT_DOCPRINT.
VIEWSTATUS_SOLIDBKGND
Value: 2
The object has a solid background (consisting in a solid color, not a brush pattern). This bit is meaningful only if VIEWSTATUS_OPAQUE is set.

This bit applies only to CONTENT related aspects and not to DVASPECT_ICON or DVASPECT_DOCPRINT.
VIEWSTATUS_DVASPECTOPAQUE
Value: 4
The object supports DVASPECT_OPAQUE. All IViewObjectEx methods taking a drawing aspect as a parameter can be called with this aspect.
VIEWSTATUS_DVASPECTTRANSPARENT
Value: 8
The object supports DVASPECT_TRANSPARENT. All IViewObjectEx methods taking a drawing aspect as a parameter can be called with this aspect.
VIEWSTATUS_SURFACE
Value: 16
The object supports a 2-dimensional surface.
VIEWSTATUS_3DSURFACE
Value: 32
The object supports a 3-dimensional surface.
