这种方法不使用
Frame
对象,而是创建一个非常大的带有
Scrollbars
的
Canvas
,并要求您提供要在其中显示的图像。
然后使用self.root.wm_attributes("-fullscreen", 1)
和self.root.wm_attributes("-top", 1)
设置屏幕。
按Esc键或Alt-F4键关闭。
import tkinter as tk
from tkinter import filedialog as fido
class BigScreen:
def __init__( self ):
self.root = tk.Tk()
self.root.rowconfigure(0, weight = 1)
self.root.columnconfigure(0, weight = 1)
w, h = self.root.winfo_screenwidth(), self.root.winfo_screenheight()
self.canvas = tk.Canvas(self.root, scrollregion = f"0 0 {w*2} {h*2}")
self.canvas.grid(row = 0, column = 0, sticky = tk.NSEW)
self.makescroll(self.root, self.canvas )
self.imagename = fido.askopenfilename( title = "Pick Image to View" )
if self.imagename:
self.photo = tk.PhotoImage(file = self.imagename).zoom(2, 2)
self.window = self.canvas.create_image(
( 0, 0 ), anchor = tk.NW, image = self.photo)
self.root.bind("<Escape>", self.closer)
self.root.wm_attributes("-fullscreen", 1)
self.root.wm_attributes("-top", 1)
def makescroll(self, parent, thing):
v = tk.Scrollbar(parent, orient = tk.VERTICAL, command = thing.yview)
v.grid(row = 0, column = 1, sticky = tk.NS)
thing.config(yscrollcommand = v.set)
h = tk.Scrollbar(parent, orient = tk.HORIZONTAL, command = thing.xview)
h.grid(row = 1, column = 0, sticky = tk.EW)
thing.config(xscrollcommand = h.set)
def closer(self, ev):
self.root.destroy()
if __name__ == "__main__":
Big = BigScreen()
Big.root.mainloop()
我之前的回答超出了问题的范围,这是一个更精简的版本,更准确地回答了问题。
