Embedding cocos2d In the QT window (1)

cocos2dx\platform\qt\CCEGLView_qt.cpp

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

It contains how to use qglwidget to create a form.

Or create the glwidget first, and then use

bool CCEGLView::SetWindow(GLWidget* window)

To create a window.

Add a qwidget to export controls.

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;

}

Recompile libcocos2d

Helloworld modify appdelegate. cpp

bool AppDelegate::initInstance() 
#if (CC_TARGET_PLATFORM == CC_PLATFORM_QT)
        CCEGLView * pMainWnd = new CCEGLView();
        CC_BREAK_IF(! pMainWnd|| ! pMainWnd->Create(480, 320));
// Add. This widget cannot retain the interface externally. For example, declare window as a public variable and access it from the outside. The specific reason is unknown.
        QWidget *window = new QWidget();
        window->setAttribute(Qt::WA_DeleteOnClose);
        QHBoxLayout *layout = new QHBoxLayout(window);
        layout->addWidget(pMainWnd->widget);
        window->show();
#endif
