我試圖避免這個令人討厭的重疊,SideView
和ListView
似乎幻想。這裏是演示了該問題的例子:QML ListView,SwipeView等 - 避免其他UI組件的重疊
注:看左邊的綠色矩形,當你刷卡SwipeView
,也是標籤,當你向下滾動ListView
的main.cpp

QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl(QLatin1String("qrc:/main.qml")));
return app.exec();

詳細的問題是好的,但這個有點太多了。如果您可以發佈一個能夠重現問題的超簡化示例(即一個完整的,可運行的示例),而不是我們必須以某種方式放在一起的幾個片段,那將是一件好事。 – Mitch
對,對不起。我實際上找到了解決我的問題的方法。似乎有一個「剪輯」屬性,我完全錯過了。基本上,當你將它設置爲'true'(不知道爲什麼它默認沒有設置該值),它消除了重疊其他事情的這種惱人的效果。 – rbaleksandar
[This](http://doc.qt.io/qt-5/qtquick-performance.html#clipping)是原因。 :) – Mitch
