CButtonST|CUniButton等按钮类的使用

CButtonST

CButtonST类的使用参考链接：http://www.cnblogs.com/lidabo/archive/2012/12/17/2821122.html

CCeButtonST

CCeButtonST是和CButtonST类（VC6.0 ）相对应的EVC（Embedded Visual C++）版本。

CUniButton

CUniButton主要用于创建不规则形状的按钮。

1、首先下载UniButton.cpp和UniButton.h文件

2、用VS2010创建基于对话框的MFC应用程序

3、将UniButton.cpp和UniButton.h文件添加入本工程，其后会多出一个CUniButton类

4、通过类向导为本对话框添加CUniButton类的成员对象以及定义按钮ID（添加到C***Dlg.h中），代码如下所示：

public:

    CUniButton m_Btn1;

    CUniButton m_Btn2;

    CUniButton m_Btn3;

    CUniButton m_Btn4;

    CUniButton m_Btn5;

    enum {UNI_BTN1 = 1001, UNI_BTN2 = 1002, UNI_BTN3 = 1003, UNI_BTN4 = 1004, UNI_BTN5 = 1005};

    CUniButton m_BtnLeft;

    CUniButton m_BtnRight;

    CUniButton m_BtnUp;

    CUniButton m_BtnDown;

    CUniButton m_BtnMid;

    enum {UNI_BTNL = 1006, UNI_BTNR = 1007, UNI_BTNU = 1008, UNI_BTND = 1009, UNI_BTNM = 1010};

5、在本对话框源文件（C***Dlg.cpp）的OnInitDialog()函数中添加以下代码：

//btn1

    HRGN r1;

    HDC hDC = CreateCompatibleDC(GetDC() -> GetSafeHdc());

    r1 = CreateEllipticRgn(0, 0, 63, 31);

    m_Btn1.Create(_T("Btn 1"), WS_CHILD | WS_VISIBLE, CPoint(100, 15), r1, this, UNI_BTN1, 2, GetSysColor(COLOR_BTNFACE), RGB(0, 255, 0), RGB(0, 255, 0), GetSysColor(COLOR_BTNFACE)); 

    DeleteObject(r1);



    //btn2

    HRGN r2;

    LOGFONT lf;

    GetFont() -> GetLogFont(&lf);

    lf.lfHeight = -128;

    lf.lfWeight = 1000;

    HFONT hFont = CreateFontIndirect(&lf);

    HFONT hOldFont = (HFONT) SelectObject(hDC, hFont);

    r2 = CreateRectRgn(0, 0, 0, 0);



    int mode = SetBkMode(hDC, TRANSPARENT);

    BeginPath(hDC);

    TextOut(hDC, 0, 0, _T("高"), 1);

    EndPath(hDC);

    r2 = PathToRegion(hDC);

    SetBkMode(hDC, mode);



    m_Btn2.Create(_T(""), WS_CHILD | WS_VISIBLE, CPoint(15, 30), r2, this, UNI_BTN2, RGB(255, 255, 0));



    SelectObject(hDC, hOldFont);

    DeleteObject(hFont);

    DeleteObject(r2);



    //btn3

    HRGN r3;

    BeginPath(hDC);

    MoveToEx(hDC, 0, 32, NULL);

    LineTo(hDC, 48, 32);

    LineTo(hDC, 48, 16);

    LineTo(hDC, 96, 48);

    LineTo(hDC, 48, 80);

    LineTo(hDC, 48, 64);

    LineTo(hDC, 0, 64);

    LineTo(hDC, 0, 32);

    EndPath(hDC);

    //r3 = CreateRectRgn(0, 0, 63, 63);

    r3 = PathToRegion(hDC);

    m_Btn3.Create(_T("Btn 3"), WS_CHILD | WS_VISIBLE, CPoint(150, 50), r3, this, UNI_BTN3, 2, RGB(250, 207, 194), RGB(255, 0, 0), RGB(255, 0, 0), GetSysColor(COLOR_BTNFACE)); 



    DeleteObject(r3);

    DeleteObject(hDC);



    //btn4

    HRGN r4;

    hDC = CreateCompatibleDC(GetDC() -> GetSafeHdc());

    BeginPath(hDC);

    MoveToEx(hDC, 31, 15, NULL);

    CPoint p[7];

    p[ 0] = CPoint(5, 0);

    p[ 1] = CPoint(0, 55);

    p[ 2] = CPoint(0, 28);

    p[ 3] = CPoint(31, 64);

    p[ 4] = CPoint(59, 55);

    p[ 5] = CPoint(59, 0);

    p[ 6] = CPoint(31, 15);

    PolyBezier(hDC, &p[0], 7);

    EndPath(hDC);

    r4 = CreateRectRgn(0, 0, 63, 63);

    r4 = PathToRegion(hDC);

    m_Btn4.Create(_T("Btn 4"), WS_CHILD | WS_VISIBLE, CPoint(200, 10), r4, this, UNI_BTN4, 2, RGB(151, 244, 219), RGB(211, 247, 254), RGB(211, 247, 254), GetSysColor(COLOR_BTNFACE)); 



    DeleteObject(r4);

    DeleteObject(hDC);



    //btn5

    HRGN r5,r51,r52;

    r5 = CreateRectRgn(16, 0, 80, 31);

    r51 = CreateEllipticRgn(0, 0, 32, 32);

    r52 = CreateEllipticRgn(64, 0, 96, 32);

    CombineRgn(r5, r5, r51, RGN_OR);

    CombineRgn(r5, r5, r52, RGN_OR);

    m_Btn5.Create(_T("Btn 5"), WS_CHILD | WS_VISIBLE, CPoint(180, 80), r5, this, UNI_BTN5, 2, GetSysColor(COLOR_BTNFACE), RGB(211, 247, 254), RGB(211, 247, 254), GetSysColor(COLOR_BTNFACE)); 

    DeleteObject(r5);

    DeleteObject(r51);

    DeleteObject(r52);

6、运行效果如下所示：

注：

若为动态生成的以上按钮添加消息响应请参考本人的另一篇博客:

MFC动态按钮的创建及其消息响应(自定义消息)

7、上面的Button1是我静态添加的按钮，测试之用；绿色矩形是我为在对话框测试画矩形之用，代码在OnPaint()函数中：

void CbuttonDlg::OnPaint()

{

    if (IsIconic())

    {

        CPaintDC dc(this); // 用于绘制的设备上下文



        SendMessage(WM_ICONERASEBKGND, reinterpret_cast<WPARAM>(dc.GetSafeHdc()), 0);



        // 使图标在工作区矩形中居中

        int cxIcon = GetSystemMetrics(SM_CXICON);

        int cyIcon = GetSystemMetrics(SM_CYICON);

        CRect rect;

        GetClientRect(&rect);

        int x = (rect.Width() - cxIcon + 1) / 2;

        int y = (rect.Height() - cyIcon + 1) / 2;



        // 绘制图标

        dc.DrawIcon(x, y, m_hIcon);

    }

    else

    {

        //CDialogEx::OnPaint();



        //画矩形

        CPaintDC dc(this); // 用于绘制的设备上下文



        CPen pen(PS_SOLID,1,RGB(255,0,0));

        //CBrush* pBrush=CBrush::FromHandle((HBRUSH)GetStockObject(NULL_BRUSH));

        //dc.SelectObject(pBrush);

        CBrush brush(RGB(0,255,0));

        dc.SelectObject(brush);

        //CClientDC dc(this);

        dc.SelectObject(&pen);

        dc.Rectangle(500,200,550,300);

    }

}

CRoundButton

CRoundButton主要用于创建圆形按钮，如果需要请百度，本文不做具体介绍。

CSXButton

CSXButton也是不错的派生于CButton的按钮扩展类，本人未曾使用，博友可尝试使用一下
