class CGXGridHint: public CObject

The CGXGridHint class is meant to be instantiated when views need to be updated after a change of the document. Instances of CGXGridHint are so-called “hint objects”.

The CGXGridCore class has several update-methods. Each update-method can create a hint object with a unique id specifying the update-method. Further attributes of the hint are filled with the parameters of the update-method and the view type. See m_id for hint-ids.

A hint is passed to CDocument::UpdateAllViews which passes the hint to each view by calling CView::OnUpdate.

CGXGridHint contains the following attributes:

• UINT m_id;
  
  
• int nViewID;
  
  
• CGXRange range;
  
  
• const CGXStyle* pStyle;
  
  
• GXModifyType mt;
  
  
• ROWCOL nRow1, nRow2, nRow3;
  
  
• ROWCOL nCol1, nCol2, nCol3;
  
  
• LONG lParam;
  
  
• DWORD dwParam;
  
  
• void* vptr;
  
  
• UINT flags;

m_id and nViewID must be set. All others are optional.

See the corresponding update-methods to know which attributes they are using.
