如何将Tkinter GUI中的视频控件定位到左上角？

你当前代码里用lblVideo.pack()默认会将标签组件置于窗口顶部居中位置，要放到左上角，有两种简单的修改方式：

方式一：使用place()布局 #

直接用place()指定左上角坐标（x=0, y=0），替换原来的pack()：

from tkinter import *
from tkvideo import tkvideo

window = Tk()
window.geometry("1481x929")
window.configure(bg = "#ffffff")

canvas = Canvas(
    window,
    bg = "#ffffff",
    height = 929,
    width = 1481,
    bd = 0,
    highlightthickness = 0,
    relief = "ridge")


canvas.place(x = 0, y = 0)

window.title("Video player")

lblVideo = Label(window)
# 替换pack为place，指定左上角坐标
lblVideo.place(x=0, y=0)

player = tkvideo("prediction.mp4", lblVideo, loop=1, size=(700,500))
player.play()

window.resizable(False, False)
window.mainloop()

方式二：调整pack()的参数 #

通过设置anchor='nw'（西北方向，即左上角），同时关闭自动填充和扩展：

from tkinter import *
from tkvideo import tkvideo

window = Tk()
window.geometry("1481x929")
window.configure(bg = "#ffffff")

canvas = Canvas(
    window,
    bg = "#ffffff",
    height = 929,
    width = 1481,
    bd = 0,
    highlightthickness = 0,
    relief = "ridge")


canvas.place(x = 0, y = 0)

window.title("Video player")

lblVideo = Label(window)
# 调整pack参数，锚定左上角
lblVideo.pack(anchor='nw', fill=None, expand=False)

player = tkvideo("prediction.mp4", lblVideo, loop=1, size=(700,500))
player.play()

window.resizable(False, False)
window.mainloop()

两种方式都能让视频标签固定在GUI的左上角，你可以根据后续布局需求选择适合的方式。
