將一個Tab從QtabBar拖放到一個拆分的Widget中的其他QtabBar Qt

我怎樣才能存檔這個： - 我需要拖放一個tabBar選項卡到其他tabBar在拆分的小部件？我已經子類化QtabBar並實現拖放事件，我已經可以拖動它與正確的像素圖等，也可以放入相同的tabBar，但不在另一個.. 得到這個錯誤輸出告訴我，我沒有提供正確的參數，這裏是代碼，我簡化了它，例如，加上窗口的.JPG。將一個Tab從QtabBar拖放到一個拆分的Widget中的其他QtabBar Qt

的ColtabBar就是即時通訊做的拖放事件的子類。

您是否考慮使用QDockWidgets？他們可以被標籤和用戶拖動 – SteakOverflow

是的，我嘗試了這種方式，我做到了，但並不是我一直在尋找的方式..我喜歡做我喜歡做的事情，然後在我的腦海中，最後做到了它，超過12小時ufff會發布結果現在:)並非常感謝youuu您的建議。 @SteakOverflow –

多小時後吃的Qt的許多manyyyy頁今天在網上，我做到了我的路，現在我可以將它從一個的TabBar下降標籤對另反之亦然，而不僅僅是從選擇當前標籤，我可以選擇我想要在我的標籤欄中的每個標籤，並將拖動時顯示小標籤的像素圖...

這裏是代碼：

**編輯**

我做了更多的防彈措施，當我在索引中使用多於2個選項卡時，出現了一個錯誤，現在效果更好，當我將它放在同一個小部件中時，它會返回事件並且不執行代碼，另外懸停選項卡用鼠標右鍵也是..我希望這可以幫助任何人在未來。
