示例1: visibilityChanged
void QQuickWindowAttached::windowChanged(QQuickWindow *window)
{
if (window != m_window) {
QQuickWindow* oldWindow = m_window;
m_window = window;
if (oldWindow)
oldWindow->disconnect(this);
if (!window)
return; // No values to get, therefore nothing to emit
if (!oldWindow || window->visibility() != oldWindow->visibility())
emit visibilityChanged();
if (!oldWindow || window->isActive() != oldWindow->isActive())
emit activeChanged();
if (!oldWindow || window->activeFocusItem() != oldWindow->activeFocusItem())
emit activeFocusItemChanged();
emit contentItemChanged();
// QQuickWindowQmlImpl::visibilityChanged also exists, and window might even
// be QQuickWindowQmlImpl, but that's not what we are connecting to.
// So this is actual window state rather than a buffered or as-requested one.
// If we used the metaobject connect syntax there would be a warning:
// QMetaObjectPrivate::indexOfSignalRelative - QMetaObject::indexOfSignal:
// signal visibilityChanged(QWindow::Visibility) from QQuickWindow redefined in QQuickWindowQmlImpl
connect(window, &QQuickWindow::visibilityChanged,
this, &QQuickWindowAttached::visibilityChanged);
connect(window, &QQuickWindow::activeChanged,
this, &QQuickWindowAttached::activeChanged);
connect(window, &QQuickWindow::activeFocusItemChanged,
this, &QQuickWindowAttached::activeFocusItemChanged);
}
