Tkinter根据屏幕分辨率最大化适应屏幕

还不能够实现所有组件随分辨率自动变化

# 实现的是界面覆盖整个屏幕
from tkinter import *
import win32api, win32con
# 获取屏幕的分辨率
width = win32api.GetSystemMetrics(win32con.SM_CXSCREEN)
height = win32api.GetSystemMetrics(win32con.SM_CYSCREEN)
# 设置UI界面
root = Tk()
root.geometry("%dx%d" %(width, height))
root.resizable(False, False)
root.mainloop()
# 实现的是界面最大化
from tkinter import *
root = Tk()
root.state("zoomed")
root.mainloop()

可以结合一个python任意区域截图的案例进行分析:

fade away...do over again...

fade away...do over again...

歌い始めの一文字目 いつも迷ってる

歌い始めの一文字目 いつも迷ってる

どうせとりとめのないことだけど

伝わらなきゃもっと意味がない

どうしたってこんなに複雑なのに

どうしたってこんなに複雑なのに

噛み砕いてやらなきゃ伝わらない

ほら結局歌詞なんかどうだっていい

僕の音楽なんかこの世になくたっていいんだよ

Everybody don't know why.

Everybody don't know why.

Everybody don't know much.

僕は気にしない 君は気付かない

何処にももういないいない

Everybody don't know why.

Everybody don't know why.

Everybody don't know much.

忘れていく 忘れられていく

We don't know,We don't know.

目の前 広がる現実世界がまた歪んだ

目の前 広がる現実世界がまた歪んだ

何度リセットしても

僕は僕以外の誰かには生まれ変われない

「そんなの知ってるよ」

気になるあの子の噂話も

シニカル標的は次の速報

麻痺しちゃってるこっからエスケープ

麻痺しちゃってるこっからエスケープ

遠く遠くまで行けるよ

安定なんてない 不安定な世界

安定なんてない 不安定な世界

安定なんてない きっと明日には忘れるよ

fade away...do over again...

fade away...do over again...

そうだ世界はどこかがいつも嘘くさい

そうだ世界はどこかがいつも嘘くさい

綺麗事だけじゃ大事な人たちすら守れない

くだらない 僕らみんなどこか狂ってるみたい

本当のことなんか全部神様も知らない

Everybody don't know why.

Everybody don't know why.

Everybody don't know much.

僕は気にしない 君は気付かない

何処にももういないいない

Everybody don't know why.

Everybody don't know why.

Everybody don't know much.

忘れていく 忘れられていく

We don't know,We don't know.
