[英]drag and drop a Tab from a QtabBar to other QtabBar in a splitted Widget PyQt Qt
我該如何存檔: - 我需要將一個選項卡從其 tabBar 拖放到拆分小部件中的其他 tabBar? 我已經將 QtabBar 子類化並實現了拖放事件,我已經可以使用正確的像素圖等拖動它,並且我也可以將它放到同一個 tabBar 中,但不能放到另一個 tabBar 中……在輸出中得到這個錯誤告訴我我沒有提供正確的參數,這里是代碼,我簡化了 make it 和 example,以及窗口的 .JPG。

ColtabBar是我執行拖放事件的子類。
幾個小時后,今天在網上吃了很多 Qt 頁面,我按照自己的方式做了,現在我可以將標簽從一個 tabBar 拖放到另一個 tabBar,反之亦然,而不僅僅是從選擇當前選項卡,我可以在選項卡欄中選擇我想要的每個選項卡,並在拖動時向我顯示小選項卡的像素圖...
這是代碼:
** 編輯 **
我使它更加防彈,當我使用超過 2 個標簽的索引時,我有一個錯誤,現在工作得更好,當我把它放在同一個小部件中時,它返回事件而不執行代碼,加上懸停也可以使用鼠標右鍵選擇選項卡.. 我希望這可以幫助將來的任何人。

這是從別人的代碼修改而來的,也許是上面的例子之一。
