使用tkinter畫GUI時需要讓視窗自動居中,以下便是實現方法:

# 通過win32api獲取系統螢幕的解析度
def get_system_metrics():
    from win32api import GetSystemMetrics
    return GetSystemMetrics(0),GetSystemMetrics(1)

# 傳入視窗大小(解析度)計算出視窗居中的位置
def get_window_positons(width,height):
    system_metrics =get_system_metrics()
    window_x_position = (system_metrics[0
 
] - width)//2
    window_y_position = (system_metrics[1] - height) // 2
    return window_x_position,window_y_position

# 測試視窗
def test_window():
    import tkinter as tk

    root = tk.Tk()
    root_width = 300
    root_height = 150
    pos = get_window_positons(root_width, root_height)
    root.geometry(f'{root_width}x{root_height}+{pos[0]}+{pos[1]}'
 
)  
    tk.mainloop()

if __name__ == '__main__':
    test_window()
