VC++ 2010中实现自定义窗口按钮控件

1. 新建一个MFC类使得它继承与CButton类；

2.

2.在生成的类中添加变量

#pragma once

// CCustomButton

class CCustomButton : public CButton

{

public:

}; CCustomButton(); virtual ~CCustomButton(); BOOL m_IsPressed; DECLARE_MESSAGE_MAP() virtual void DrawItem(LPDRAWITEMSTRUCT /*lpDrawItemStruct*/); afx_msg void OnLButtonUp(UINT nFlags, CPoint point); afx_msg void OnLButtonDown(UINT nFlags, CPoint point); afx_msg BOOL OnEraseBkgnd(CDC* pDC);

DECLARE_DYNAMIC(CCustomButton) protected: public:

3.。重写方法WM_BUTTONDOWN WM_LBUTTONUP

// CustomButton.cpp : 实现文件

//

#include "stdafx.h"

#include "just test.h"

#include "CustomButton.h"

// CCustomButton

IMPLEMENT_DYNAMIC(CCustomButton, CButton)

CCustomButton::CCustomButton()

{

}

CCustomButton::~CCustomButton()

{

}

BEGIN_MESSAGE_MAP(CCustomButton, CButton)

ON_WM_LBUTTONUP()

ON_WM_LBUTTONDOWN()

ON_WM_ERASEBKGND()

END_MESSAGE_MAP()

// CCustomButton 消息处理程序

void CCustomButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)

{

CRect rect;

GetClientRect(rect);

CDC dc;

dc.Attach(lpDrawItemStruct->hDC);

dc.SetBkMode(TRANSPARENT);

CBrush m_Brush;

m_Brush.CreateStockObject(NULL_BRUSH);

dc.SelectObject(&m_Brush);

if(m_IsPressed)

{

CPen pen(PS_SOLID,2,RGB(255,2,0));

dc.SelectObject(&pen);

HRGN rgn = CreateEllipticRgn(0,0,rect.Width(),rect.Height());

SetWindowRgn(rgn,TRUE);

dc.Ellipse(0,0,rect.Width(),rect.Height());

dc.SetTextColor(RGB(0,0,255));

}

else

{

CPen pen(PS_SOLID,2,RGB(5,255,0));

dc.SelectObject(&pen);

HRGN rgn = CreateEllipticRgn(0,0,rect.Width(),rect.Height());

SetWindowRgn(rgn,TRUE);

dc.Ellipse(0,0,rect.Width(),rect.Height());

dc.SetTextColor(RGB(120,0,190));

}

CString str;

GetWindowText(str);

dc.DrawText(str,CRect(0,0,rect.Width(),rect.Height()),DT_CENTER|DT_VCENTER|DT_SINGLELINE);

// TODO: 添加您的代码以绘制指定项

}

void CCustomButton::OnLButtonUp(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

m_IsPressed = FALSE;

CButton::OnLButtonUp(nFlags, point);

}

void CCustomButton::OnLButtonDown(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

m_IsPressed = TRUE;

CButton::OnLButtonDown(nFlags, point);

}

BOOL CCustomButton::OnEraseBkgnd(CDC* pDC)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

return TRUE;

//return CButton::OnEraseBkgnd(pDC);

}

4、最后改写WM_ERASEBKGND 禁止窗口重画

然后关联控件变量

到此为止，我们已经我们完成了自定义按钮控江
