MFC动态创建按钮,并在按钮上实现位图的切换显示

动态创建按钮,并在按钮中添加位图,通过单击按钮显示不同的位图,可设置为显示按钮按下和弹起两种状态。只要判断a值从而输入不同的响应代码。

1、在头文件中添加:

    CButton *pBtn;

2、在初始化函数中添加:

    pBtn = new CButton();

    pBtn->Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON|BS_BITMAP, CRect(0,0,100,40), this, IDC_BUTTON);//按钮显示名、属性、ID号

    pBtn->MoveWindow(CRect(400,100,500,140));//位置和按钮大小

    pBtn->SetBitmap((HBITMAP)LoadImage(AfxGetInstanceHandle(), "1.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION));//插入位图的,位图的位置要放在程序中

    此时运行程序就可显示按钮,并且如果有位图,位图会显示在按钮上面;

3、在Resource.h中

    添加ID号:比如#define IDC_BUTTON 1002

4、在头文件下方

    protected:

    //{{AFX_MSG(CMy3View)

        // NOTE - the ClassWizard will add and remove member functions here.

        //    DO NOT EDIT what you see in these blocks of generated code !

    //}}AFX_MSG

    afx_msg void OnButton();//这句函数声明

    DECLARE_MESSAGE_MAP()

5、在

    BEGIN_MESSAGE_MAP(CMy3View, CFormView)

    //{{AFX_MSG_MAP(CMy3View)

        // NOTE - the ClassWizard will add and remove mapping macros here.

        //    DO NOT EDIT what you see in these blocks of generated code!

    //}}AFX_MSG_MAP

    // Standard printing commands

    ON_BN_CLICKED(IDC_BUTTON, OnButton)//在外面(ID号,响应函数名)

    END_MESSAGE_MAP()

6、手动添加响应函数

    void CMyView::OnButton()

    {

        MessageBox("响应函数添加测试成功");

    }

7、在头文件中添加一个整形的成员变量

    int a;

8、构造函数中初始化

    a = 0;

9、在按钮响应函数中添加

    void CMyView::OnButton()

    {

        if(a%2 == 0)

        {    

            pBtn->SetBitmap((HBITMAP)LoadImage(AfxGetInstanceHandle(), "2.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION));

        }

        else if(a%2 == 1)

        {

            pBtn->SetBitmap((HBITMAP)LoadImage(AfxGetInstanceHandle(), "1.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION));

        }

        a++;

    }

如果单纯的实现按钮的位图切换的话,建议使用CBitmapButton类
