qt - 如何将 QGrapicsView 嵌入到 QtQuick 窗口中？

Question

我有一个由 QGraphicsView/QGraphicsScene 编写的游戏。现在我想将它嵌入到由 QQuickWindow/QQuickItem 编写的 QtQuick 应用程序中。我该怎么做？

原始游戏代码：

    TileScene *scene = new TileScene(":/tileset.png", ":/test.tmx");

    NPC *joe = new NPC(":/nerd.png");
    scene->addCharacter(joe);
    joe->setPos(15 * TILE_WIDTH, 23 * TILE_HEIGHT);

    // Set up a view of our scene
    view = new CharacterView(scene);
    view.show();

QtQuick 应用程序：

MainContent::MainContent( QQuickItem* parent )
{
    auto gridBox = new MainContentGridBox();

    gridBox->addItem( new GameItem("Deck 01"), 0, 0);
    ...
}

//GameItem.h

class GameItem : public QQuickItem
{
    Q_OBJECT
public:
    GameItem(QString text, QQuickItem* parent = nullptr);
}

//GameItem.cpp

GameItem::GameItem(QString text, QQuickItem* parent)
{
    TileScene *scene = new TileScene(":/tileset.png", ":/test.tmx");

    NPC *joe = new NPC(":/nerd.png");
    scene->addCharacter(joe);
    joe->setPos(15 * TILE_WIDTH, 23 * TILE_HEIGHT);

    // Set up a view of our scene
    view = new CharacterView(scene);
}
