Detailed Description

Shell surface implementations should inherit from this class in order to provide an integration between the shell surface and QtQuick.

Shell integration is installed as an event filter for a QWaylandQuickShellSurfaceItem. Reimplement the event filter method and return true when you want to filter the event out, otherwise return false.

Example:

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);
}
