Windows下如何自定义窗体控件

 

Win32窗体的所有控件都认为是窗体,所以创建一个自定义的控件跟创建一个win32的窗体是相似的

参考此篇文章

先通过RegisterClassEx注册一个window class,然后就在消息循环里获取消息绘制控件.

在MFC中自定义控件

依照此思想,在MFC中也是如此做法,让一个控件继承自CWnd,然后通过AfxRegisterClass方法注册,可以参考此篇文章

主要的代码

CBitmapViewer::CBitmapViewer()

{

    RegisterWindowClass();

}



CBitmapViewer::~CBitmapViewer()

{

}



// Register the window class if it has not already been registered. BOOL CBitmapViewer::RegisterWindowClass()

{

    WNDCLASS wndcls;

    HINSTANCE hInst = AfxGetInstanceHandle();



    if (!(::GetClassInfo(hInst, BITMAPVIEWER_CLASSNAME, &wndcls)))

    {

        // otherwise we need to register a new class wndcls.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;

        wndcls.lpfnWndProc = ::DefWindowProc;

        wndcls.cbClsExtra = wndcls.cbWndExtra = 0;

        wndcls.hInstance = hInst;

        wndcls.hIcon = NULL;

        wndcls.hCursor = AfxGetApp()->LoadStandardCursor(IDC_ARROW);

        wndcls.hbrBackground = (HBRUSH) (COLOR_3DFACE + 1);

        wndcls.lpszMenuName = NULL;

        wndcls.lpszClassName = BITMAPVIEWER_CLASSNAME;



        if (!AfxRegisterClass(&wndcls))

        {

            AfxThrowResourceException();

            return FALSE;

        }

    }



    return TRUE;

}



///////////////////////////////////////////////////////////////////////////// // CBitmapViewer methods BOOL CBitmapViewer::Create(CWnd* pParentWnd, const RECT& rect, UINT nID, DWORD dwStyle /*=WS_VISIBLE*/)

{

    return CWnd::Create(BITMAPVIEWER_CLASSNAME, _T(""), dwStyle, rect, pParentWnd, nID);

}

默认windows系统皮肤

win32的控件在不同windows版本下皮肤不一样,默认创建的win32程序和mfc程序的皮肤还是老版本的样式.为了使用新的皮肤必须初始化一个类库

#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")

把这句话加到头文件中，然后会生产到manifest文件中

<dependency> <dependentAssembly> <assemblyIdentity type="win32" 

            name="Microsoft.Windows.Common-Controls" 

            version="6.0.0.0" 

            processorArchitecture="X86" 

            publicKeyToken="6595b64144ccf1df" 

            language="*" 

        /> </dependentAssembly> </dependency>

这个配置搞的很郁闷。。。配置。。。
