最近有个项目需要用grid ctrl 呈现多种控件类型， 而我也一直用的是codeproject上的 MFC Grid Control
， 这个控件很强大， 而且易于扩展， 源码也提供多种类型的控件， 包括checkbox， combobox， 等等。

下面就给出如何为CGridCtrl添加自己的控件类型方法， 本文是button控件

CGridCellButton头文件

/********************************************************************<br /> created: 2009/09/27<br /> created: 27:9:2009 9:14<br /> filename: /GridCtrl/NewCellTypes/GridCellButton.h<br /> file path: /GridCtrl/NewCellTypes<br /> file base: GridCellButton<br /> file ext: h<br /> author: Li JianGong</p> <p> purpose: Create button cell<br /> *********************************************************************/<br /> #include "../GridCtrl_src/GridCell.h"<br /> class CGridCellButton : public CGridCell<br /> {<br /> friend class CGridCtrl;<br /> DECLARE_DYNCREATE(CGridCellButton)<br /> public:<br /> CGridCellButton(void);<br /> ~CGridCellButton(void);<br /> public:<br /> virtual BOOL Draw(CDC* pDC, int nRow, int nCol, CRect rect, BOOL bEraseBkgnd = TRUE);<br /> protected:<br /> virtual void OnClick( CPoint PointCellRelative);<br /> protected:<br /> CRect m_rect;<br /> BOOL m_bPushing; <br /> }<br />

CGridCellButton实现文件

#include "stdafx.h"<br /> #include "../GridCtrl_src/GridCell.h"<br /> #include "../GridCtrl_src/GridCtrl.h"<br /> #include "GridCellButton.h"<br /> #ifdef _DEBUG<br /> #define new DEBUG_NEW<br /> #undef THIS_FILE<br /> static char THIS_FILE[] = __FILE__;<br /> #endif<br /> IMPLEMENT_DYNCREATE(CGridCellButton, CGridCell)<br /> CGridCellButton::CGridCellButton(void)<br /> {<br /> m_bPushing = FALSE;<br /> }<br /> CGridCellButton::~CGridCellButton(void)<br /> {<br /> }<br /> BOOL CGridCellButton::Draw(CDC* pDC, int nRow, int nCol, CRect rect, BOOL bEraseBkgnd /* = TRUE */)<br /> {<br /> m_rect = rect;<br /> pDC->SetBkMode(TRANSPARENT);<br /> rect.DeflateRect( GetMargin(), 0);<br /> CFont* pOldFont = pDC->SelectObject(GetFontObject());<br /> pDC->DrawFrameControl(rect, DFC_BUTTON, m_bPushing?DFCS_BUTTONPUSH | DFCS_PUSHED:DFCS_BUTTONPUSH);<br /> COLORREF ColorCurrent = pDC->GetTextColor();<br /> pDC->SetTextColor(::GetSysColor(COLOR_BTNTEXT));<br /> pDC->DrawText(GetText(), -1, rect, DT_CENTER|DT_VCENTER|DT_SINGLELINE|DT_END_ELLIPSIS);<br /> pDC->SetTextColor( ColorCurrent);<br /> return TRUE;<br /> }<br /> void CGridCellButton::OnClick(CPoint PointCellRelative)<br /> {<br /> m_bPushing = !m_bPushing;<br /> GetGrid()->InvalidateRect(m_rect);<br /> }<br />

使用方法：

CGridCtrl m_gridAddOn; //dlg.h文件<br /> //////////////////////////////////////<br /> //dlg.cpp文件<br /> m_gridAddOn.Create(rect, this, IDC_LIST);<br /> m_gridAddOn.Refresh();<br /> m_gridAddOn.SetColumnCount(4);<br /> m_gridAddOn.SetFixedColumnCount(0);<br /> m_gridAddOn.SetFixedRowCount(1);<br /> m_gridAddOn.SetColumnWidth(0, 95);<br /> m_gridAddOn.SetColumnWidth(1, 95);<br /> m_gridAddOn.SetColumnWidth(2, 70);<br /> m_gridAddOn.SetColumnWidth(3, 145);<br /> m_gridAddOn.SetItemText(0, 0, _T("Application"));<br /> m_gridAddOn.SetItemText(0, 1, _T("Status"));<br /> m_gridAddOn.SetItemText(0, 2, _T("Action"));<br /> m_gridAddOn.SetItemText(0, 3, _T("Auto-Start"));<br /> m_gridAddOn.InsertRow(_T("item"));<br /> m_gridAddOn.SetItemText(0, 0, _T("Simulator"));<br /> m_gridAddOn.SetItemText(0, 1, _T("Stop"));<br /> m_gridAddOn.SetItemText(0, 2, _T("Start"));<br /> if (!m_gridAddOn.SetCellType(0, 2, RUNTIME_CLASS(CGridCellButton)))<br /> return NULL;<br /> m_gridAddOn.SetItemText(0, 3, _T(""));<br />

效果如下：
