Python界面设计

pack()默认居中，从上而下

def init_window(title,w,h,icon_path):
    window = tk.Tk()
    window.title(title)
    window.iconphoto(False, tk.PhotoImage(file=icon_path))
    screen_width, screen_height = window.maxsize()
    top_x = screen_width/2 - w/2
    top_y = screen_height/2 - h/2
    window.geometry("%dx%d+%d+%d" %(w,h,top_x,top_y))

    btn=Button(window,text='选择图片')
    btn.pack()
    window.mainloop()
