Introduction
This example demonstrates how to add "merge cells" ability to Chris Maunder's MFC Grid control (derived from CWnd).
The example modifies only two classes: CGridCellBase and CGridCtrl. In the class CGridCellBase ,the following four private member variables are added:
CCellRange m_MergeRange;
bool m_IsMergeWithOthers;
CCellID m_MergeCellID;
bool m_Hide;
Six public member functions are also added:
void UnMerge();
virtual bool IsShow() ;
virtual CCellRange GetMergeRange();
virtual bool IsMergeWithOthers();
virtual CCellID GetMergeCellID();
virtual void SetMergeCellID(CCellID cell);
In the class CGridCtrl, the following six public member functions are added:
CGridCellBase* GetCell(CCellID cell);
CCellID GetMergeCellID(CCellID cell);
void UnMergeSelectedCells();
void MergeSelectedCells();
void UnMergeCells(int nStartRow, int nStartCol, int nEndRow, int nEndCol);
void MergeCells(int nStartRow, int nStartCol, int nEndRow, int nEndCol);
Usage
- Use
CGridCtrl::MergeSelectedCells() and MergeCells() to merge the selected cells;
- Use
CGridCtrl::UnMergeSelectedCells() and UnMergeCells() to restore the selected cell to its original state.
