在win32/MFC 程序中使用QT控件。。。。。。。

暂时讲解qt控件以DLL形式附加到win32/mfc程序中 环境 vs2005集成qt编译环境+qt4.5

1.使用QT提供的两者的交互框架 http://download.csdn.net/source/3539936

2.创建QT DLL

2.将src 的.h .cpp文件全部复制你的dll工程目录下，然后添加到工程里

3.在qt的dll中定义

BOOL WINAPI DllMain( HINSTANCE hInstance, DWORD dwReason, LPVOID lpvReserved )

{

static bool ownApplication = FALSE;

if ( dwReason == DLL_PROCESS_ATTACH )

ownApplication = QMfcApp::pluginInstance( hInstance );

if ( dwReason == DLL_PROCESS_DETACH && ownApplication )

delete qApp;

return TRUE;

}

extern "C" __declspec(dllexport) void ShowControl( HWND parent )

{

QWinWidget *win=new QWinWidget( parent );

QHBoxLayout *hbox = new QHBoxLayout( win );

QLabel *label = new QLabel( "Enter text:", win );

QLineEdit *edit = new QLineEdit( win );

hbox->addWidget( label );

hbox->addWidget( edit );

win->move( 0, 0 );

win->show();

}

win32/mfc程序中

typedef void(*DeShowControl)( HWND parent );

DeshowDialog ShowControl;

HMODULE hm=LoadLibraryA("qtwin.dll");

ShowControl=(DeshowDialog)GetProcAddress(hm,"showDialog");

ShowControl(hWnd);

效果如图

win32win是win32 api创建的窗口

enter text::是用qt创建的两个控件
