Python Tkinter 中的滑鼠位置
在大型應用程式中,“事件”非常有助於執行和管理多項任務。我們可以使用 bind('handler', 'callback') 方法將特定事件與鍵盤按鈕或滑鼠按鈕繫結在一起。為了構建螢幕保護程式、2D 或 3D 遊戲,通常會追蹤滑鼠指標及其運動。為了列印指標的座標,我們必須將 Motion 與一個回撥函式繫結在一起,該回調函式獲取指標在 x 和 y 變數中的位置。
示例
#Import tkinter library from tkinter import * #Create an instance of tkinter frame or window win= Tk() #Set the geometry of tkinter frame win.geometry("750x250") def callback(e): x= e.x y= e.y print("Pointer is currently at %d, %d" %(x,y)) win.bind('<Motion>',callback) win.mainloop()
輸出
執行以上程式碼,只要我們在視窗上懸停,就會列印指標的實際位置。
在控制檯中,當你在螢幕上移動滑鼠時,將看到滑鼠指標的實際位置。
