COleServerItem::OnDrawEx

virtual BOOL OnDrawEx( CDC* pDC, DVASPECT nDrawAspect, CSize& rSize );

Return Value

Nonzero if the item was successfully drawn; otherwise 0.

Parameters

pDC

A pointer to the CDC object on which to draw the item. The DC is automatically connected to the attribute DC so you can call attribute functions, although doing so would make the metafile device-specific.

nDrawAspect

A value from the DVASPECT enumeration. This parameter can have any of the following values:

• DVASPECT_CONTENT   Item is represented in such a way that it can be displayed as an embedded object inside its container.
  
  
• DVASPECT_THUMBNAIL   Item is rendered in a “thumbnail” representation so that it can be displayed in a browsing tool.
  
  
• DVASPECT_ICON   Item is represented by an icon.
  
  
• DVASPECT_DOCPRINT   Item is represented as if it were printed using the Print command from the File menu.

rSize

Size of the item in HIMETRIC units.

Remarks

Called by the framework for all drawing. The default implementation calls OnDraw when DVASPECT is equal to DVASPECT_CONTENT; otherwise it fails.

Override this function to provide presentation data for aspects other than DVASPECT_CONTENT, such as DVASPECT_ICON or DVASPECT_THUMBNAIL.
