全屏tkinter canvas python

Question

您好，如何使全屏显示tkinter.Canvas？你能帮助我吗？这是我的代码：

import tkinter
import datetime
import sys
import os

uvodcanvas = tkinter.Canvas(width=400,height=200,bg="white")
uvodcanvas.pack()

tkinter.mainloop()

Answer 1

我不确定我是否完全理解您的问题，您不是很明确。我认为以下代码将为您提供帮助。查看一些tkinter教程，您缺少一些基础知识。

import tkinter
root = tkinter.Tk()
w, h = root.winfo_screenwidth(), root.winfo_screenheight()
root.geometry("%dx%d+0+0" % (w, h))
uvodcanvas = tkinter.Canvas(root, width=400,height=200,bg="white")
uvodcanvas.pack()
tkinter.mainloop()

Answer 2

您需要使主窗口全屏显示，然后将画布配置为占据整个主窗口：

import tkinter as tk

root = tk.Tk()
root.attributes('-fullscreen', True) # make main window full-screen

canvas = tk.Canvas(root, bg='white', highlightthickness=0)
canvas.pack(fill=tk.BOTH, expand=True) # configure canvas to occupy the whole main window

root.mainloop()

您可以将root.attributes设置为全屏。以下示例显示了在按Escape键时如何从全屏切换到大小窗口，反之亦然

import tkinter as tk

def toggle_fs(dummy=None):
    state = False if root.attributes('-fullscreen') else True
    root.attributes('-fullscreen', state)
    if not state:
        root.geometry('300x300+100+100')

root = tk.Tk()
tk.Canvas(root, bg='cyan').pack(expand=True, fill=tk.BOTH)
root.attributes('-fullscreen', True)

root.bind('<Escape>', toggle_fs)

root.mainloop()
