cocos2dx\platform\qt\CCEGLView_qt.cpp

bool CCEGLView::Create(int iWidth, int iHeight)

中包含了是如何利用QGLWidget 来创建一个窗体的。

或者是先创建号GLWidget, 然后通过 

bool CCEGLView::SetWindow(GLWidget* window)

来制定窗口。

增加QWidget 来导出控件.

cocos2dx\platform\qt\CCEGLView_qt.h:

public:

    QWidget *widget;

cocos2dx\platform\qt\CCEGLView_qt.cpp:

bool CCEGLView::Create(int iWidth, int iHeight)

{

    widget = new QWidget;

    widget->setAttribute(Qt::WA_PaintOnScreen);

    widget->setFixedSize(iWidth, iHeight);

    m_window = new GLWidget(iWidth,iHeight, CCDirector::sharedDirector(), widget);

    m_window->setMouseMoveFunc(&cocos2d::mouseMove);

    m_window->setMousePressFunc(&cocos2d::mousePress);

    m_window->setMouseReleaseFunc(&cocos2d::mouseRelease);

    m_window->setWindowFlags(m_window->windowFlags()& ~Qt::WindowMaximizeButtonHint);

    m_window->setFixedSize(iWidth, iHeight);

    widget->show();

    m_bIsSubWindow = true;

    bIsInit = true;

    s_pMainWindow = this;

    m_sSizeInPoint.width = iWidth;

    m_sSizeInPoint.height = iHeight;

    m_bOrientationInitVertical = (CCDeviceOrientationPortrait == m_eInitOrientation

                || kCCDeviceOrientationPortraitUpsideDown == m_eInitOrientation) ? true : false;

	return true;

}

重新编译libcocos2d

HelloWorld

bool AppDelegate::initInstance() 

#if (CC_TARGET_PLATFORM == CC_PLATFORM_QT)

        CCEGLView * pMainWnd = new CCEGLView();

        CC_BREAK_IF(! pMainWnd|| ! pMainWnd->Create(480, 320));

// 添加, 这个widget还不能向外保留接口，比如把window 声明为public 变量，从外部访问它。具体原因还不知道

        QWidget *window = new QWidget();

        window->setAttribute(Qt::WA_DeleteOnClose);

        QHBoxLayout *layout = new QHBoxLayout(window);

        layout->addWidget(pMainWnd->widget);

        window->show();

#endif
