详细描述

壳表实现应该从这个类继承，以便在壳表和 QtQuick 之间提供集成。

壳集成作为 QWaylandQuickShellSurfaceItem 的事件过滤器安装。重新实现事件过滤器方法，当你想要过滤事件时返回 true，否则返回 false。

示例

class MyShellIntegration : public QWaylandQuickShellIntegration
{
    Q_OBJECT
public:
    MyShellIntegration(QObject *parent = nullptr);

protected:
    bool eventFilter(QObject *object, QEvent *event) override;
};

MyShellIntegration::MyShellIntegration(QObject *parent)
    : QWaylandQuickShellIntegration(parent)
{
}

bool MyShellIntegration::eventFilter(QObject *object, QEvent *event)
{
    QWaylandQuickShellSurfaceItem *shellSurfaceItem = qobject_cast<QWaylandQuickShellSurfaceItem *>(object);
    if (!shellSurfaceItem)
        return QWaylandQuickShellIntegration::eventFilter(object, event);

    if (event->type() == QEvent::MouseMove) {
        QMouseEvent *mouseEvent = static_cast<QMouseEvent *>(event);
        qDebug() << "Mouse moved on" << shellSurfaceItem << "pos:" << mouseEvent->pos();
        return true;
    }

    return QWaylandQuickShellIntegration::eventFilter(object, event);
}
