关键模拟器始终位于顶部/前台(tkinter)

我想知道我是如何总是把窗口放在前景的。如果我点击另一个区域，窗口将处于“非活动”状态，我将无法再访问它（这不是真正的问题）。例如，当我打开浏览器或游戏时，我希望它处于前景，即使我单击其他曲面时也是如此。”-“最顶端”已可用，该窗口仅在其他活动中消失。
我发布代码是为了更好地了解我的意思（但我自己认为如果有一个解决方案的话，将会有一个小的解决方案）

    mw = MainWindow()

    mw.overrideredirect(1)
    mw.wm_transient()
    mw.attributes("-transparentcolor", "red")
    mw.attributes("-topmost", True)

    mw.mainloop()

试着这样做：

from tkinter import ttk
import tkinter as tk
import keyboard

class MainWindow(tk.Tk):
    # Some constants:
    CHARACTERS_ROW_1 = tuple("qwertyuiop")
    CHARACTERS_ROW_2 = tuple("asdfghjkl")
    CHARACTERS_ROW_3 = tuple("zxcvbnm")
    CHARACTERS = (CHARACTERS_ROW_1, CHARACTERS_ROW_2, CHARACTERS_ROW_3)

    def __init__(self):
        super().__init__()

        self.event_queue = []
        self.alive = True

        self.style = ttk.Style()
        self.style.theme_use("clam")
        self.style.configure("TButton", background="red", borderwidth=0, focuscolor="none", font=("Unispace", 12))
        self.style.configure("TONE.TButton", background="#1e2224", font=("Unispace", 12), borderwidth=1,
                             foreground="#a1e0ff", bordercolor="lime", darkcolor="lime", lightcolor="lightgreen")

        self.buttons = {} # A dictionary of all of the buttons

        for row, characters in enumerate(self.CHARACTERS):
            for column, character in enumerate(characters):
                button = ttk.Button(self, style="TButton")
                button.grid(row=row, column=column)
                self.buttons.update({character: button})

        # Add a global system binding:
        keyboard.hook(self.hook)

        # Start the loop:
        self.handle_events_loop()

        # An easy way to escape the program:
        super().bind("<Escape>", lambda e: self.destroy())

    def destroy(self) -> None:
        self.alive = False
        super().destroy()

    def hook(self, event:keyboard.KeyboardEvent) -> None:
        if self.alive:
            self.event_queue.append(event)

    def handle_events_loop(self) -> None:
        if len(self.event_queue) > 0:
            # Get the first event:
            event = self.event_queue.pop(0)
            if event.name not in self.buttons.keys():
                return None
            if event.event_type == "down":
                self.show_key(event.name)
            elif event.event_type == "up":
                self.hide_key(event.name)
        # After 10 ms call `self.handle_events_loop` again
        super().after(10, self.handle_events_loop)

    def show_key(self, character:str) -> None:
        button = self.buttons[character]
        button.config(text=character, style="TONE.TButton")

    def hide_key(self, character:str) -> None:
        button = self.buttons[character]
        button.config(text="", style="TButton")

if __name__ == '__main__':
    root = MainWindow()

    # Removed for debugging
    # root.overrideredirect(True)
    root.transient()
    root.attributes("-topmost", True)
    root.attributes("-transparentcolor", "red")
    root.config(bg="red")

    root.mainloop()

我用了 keyboard.hook 挂接到所有系统范围的键盘事件。然后我使用了一个带有 tkinter 循环来处理事件。
