Windows下如何自定义窗体控件

来源：互联网发布：朱生豪情书集淘宝编辑：程序博客网时间：2024/06/06 04:24

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 methodsBOOL 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>
