暫時講解qt控制元件以DLL形式附加到win32/mfc程式中 環境 vs2005整合qt編譯環境+qt4.5

2.建立QT DLL

2.將src 的.h .cpp檔案全部複製你的dll工程目錄下，然後新增到工程裡

3.在qt的dll中定義

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程式中

typedef void(*DeShowControl)( HWND parent );

DeshowDialog ShowControl;

HMODULE hm=LoadLibraryA("qtwin.dll");

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

效果如圖

win32win是win32 api建立的視窗

enter text::是用qt建立的兩個控制元件
