Python Tkinter通过热键隐藏和显示窗口 [英] Python Tkinter hide and show window via hotkeys

问题描述

我正在尝试编写一个可以通过热键隐藏和显示的程序.我设法使用库键盘"来显示和隐藏应用程序，但是由于库的等待"功能，它阻止了文本"框正常运行.我曾尝试在Tkinter中使用键绑定，但是我遇到了另一个问题，即一旦隐藏了程序或选择了另一个应用程序，我就无法通过热键将焦点返回到隐藏的窗口.

I'm trying to write a program that I can hide and show via hotkeys. I managed to get the application to show and hide using the library "keyboard", however due to the "wait" function of the library, it prevents the Text box from functioning correctly. I have tried using the key bindings within Tkinter, however I had a different problem, whereby once the program was hidden or another application was selected, I couldn't return the focus to the hidden window via the hotkey.

import Tkinter as Tk
import keyboard

class MyApp(object):

    def __init__(self, parent):
        self.root = parent
        self.root.title("Main frame")

        self.frame = Tk.Frame(parent)
        self.frame.pack()

        self.editor = Tk.Text(self.frame)
        self.editor.pack()
        self.editor.config(font="Courier 12")
        self.editor.focus_set()


        keyboard.add_hotkey('ctrl+alt+s', self.show)
        keyboard.add_hotkey('ctrl+alt+h', self.hide)
        keyboard.wait()

        self.root.withdraw() 


    def show(self):
        self.root.update()
        self.root.deiconify()

    def hide(self):
        self.root.withdraw()


if __name__ == "__main__":
    root = Tk.Tk()
    root.geometry("800x600")
    app = MyApp(root)
    root.mainloop()

任何帮助都会很棒:)

推荐答案

只需删除此等待命令，它就是一个附加的主循环，因为Tkinter会执行其工作，因此不需要.我试图通过线程来解决您的问题，但是由于我想检查一下到底什么不起作用，所以我意外地做了我想您想要的事情.所以代码是:

Just drop this wait command, its an additional mainloop, which is not needed as Tkinter does its job. I tried to fix your problem with threading, but as I wanted to check exactly what is NOT working, I accidentially made what I suppose you wanted to. So the Code is:

import tkinter as tk
import keyboard

class App(tk.Tk):

    def __init__(self):
        super().__init__()
        self.geometry("800x600")
        self.title("Main frame")

        self.editor = Tk.Text(self)
        self.editor.pack()
        self.editor.config(font="Courier 12")
        self.editor.focus_set()


        keyboard.add_hotkey('ctrl+alt+s', self.show)
        keyboard.add_hotkey('ctrl+alt+h', self.hide)


    def show(self):
        self.update()
        self.deiconify()

    def hide(self):
        self.update()
        self.withdraw()


if __name__ == "__main__":
    App().mainloop()

我希望这对您有用.我也建议更改此关键设置.用PyZo中的那些进行测试是不可能的！它总是尝试另存为..."，我不想...

I hope this works for you. I'd also recommend changing this key settings. Testing with those in PyZo is IMPOSSIBLE! It always tries to "save as...", which I don't want to...
