把 Cocos2d 嵌入 Qt 視窗中(2)

或者是不需要修改 libcocos2dx， 通過setWindow(GLWidget*) 的方式給視窗. 如下：

AppDelegate.cpp:

#if (CC_TARGET_PLATFORM == CC_PLATFORM_QT)static CCEGLView* pMainWnd = NULL;static void mouseMove(QMouseEvent *event){    pMainWnd->mouseMove(event);}static void mousePress(QMouseEvent *event){    pMainWnd->mousePress(event);}static void mouseRelease(QMouseEvent *event){    pMainWnd->mouseRelease(event);}#endif

bool AppDelegate::initInstance() {

// ....

        pMainWnd = new CCEGLView();//        CC_BREAK_IF(! pMainWnd|| ! pMainWnd->Create(480, 320));        int iWidth = 480;        int iHeight = 320;        QWidget *w = new QWidget();        w->setAttribute(Qt::WA_DeleteOnClose);        QHBoxLayout *layout = new QHBoxLayout();        GLWidget *glWidget = new GLWidget(iWidth,iHeight, CCDirector::sharedDirector());        pMainWnd->SetWindow(glWidget);        glWidget->setMouseMoveFunc(&mouseMove);        glWidget->setMousePressFunc(&mousePress);        glWidget->setMouseReleaseFunc(&mouseRelease);        glWidget->setWindowFlags(glWidget->windowFlags()& ~Qt::WindowMaximizeButtonHint);        glWidget->setFixedSize(iWidth, iHeight);        layout->addWidget(glWidget);        layout->addWidget(new QPushButton("Cocos2dx"));        w->setLayout(layout);        w->show();

// ....

}

Test:

        CCLabelTTF *label = CCLabelTTF::labelWithString("xx", "Arial", 32);        label->setPosition( ccp(200,200) );        scene->addChild(label, 2);
空白一片.
這是由於多線程引起的。
