Tkinter實現透明窗口最簡單的方法

import tkinter as tkroot = tk.Tk() root.title('Tkinter Window Demo') root.geometry('600x400+50+50') root.resizable(False, False) root.attributes('-alpha', 0.5)root.mainloop()

動態更改鼠標樣式

import tkinter as tkroot = tk.Tk() root.title('Tkinter Window Demo') root.geometry('600x400+50+50') # root.resizable(False, False) # 禁止更改窗口大小 root.attributes('-alpha', 0.5)def change_cursor(event):if event.x in range(100, 300): # 當鼠標從距離零點100 到 300 的 x 坐標上開始時，光標變為忙碌狀態。root.config(cursor="watch")else:root.config(cursor="")root.bind("<Motion>", change_cursor)root.mainloop()

所有ttk 小部件都有 cursor 參數，允許您在鼠標懸停它們時更改光標
