我有兩個完全相同大小的圖像。一個是基礎背景圖像,另一個圖像是背景圖像的改變版本。我試圖在背景圖像的頂部顯示一個靜態大小(例如100,100)的窗口,在這些窗口中,無論鼠標移動到哪裏,它們都會排列起來。在基本圖像上覆蓋改變後的圖像的移動窗口的排序。我一直在試圖修改我在Stack Overflow的某處找到的一些基本代碼,但似乎無法弄清楚如何修改它以獲得所需的結果。如果您認爲我錯誤地採取了這種方式,或者在我錯過了某個地方的情況下,請提出另一種方法。我對tkinter很新。另外,我不需要以下圖像示例中顯示的座標系。只有圖像是好的。tkinter - 用鼠標移動顯示圖像疊加在畫布上的圖像

你讓它看起來很簡單!謝謝! – Beaker
嘿。我在那裏修改了一個可怕的錯誤。我再次混淆了tkinter mainloop的機制! (每次我回到tkinter都會發生!)。你根本不需要first_run的東西。只要刪除,你會沒事的。主循環不能像那樣工作! – ROAR
