我试图在窗口中提出申请。它基本上调整了你的监测亮度。一项职能是尽量减少适用。因此,我对尽量减少问题表示怀疑。

在第二次点击以尽量减少纽特州错误时:

下面的法典有一部分:

import ttkbootstrap as tb
import ttkbootstrap as ttk
import PIL.Image
import pystray


class DesktopBrightnessApp:
     def __init__(self):
            self.minimize_button = tb.Button(self.root, text="Minimize", 
               command=self.minimize_app)
               self.minimize_button.place(x=215, y=200)

            self.icon = pystray.Icon( icon , img, menu=pystray.Menu(
                pystray.MenuItem("Open GUI", self.on_move_clicked),
                pystray.MenuItem("Exit", self.on_move_clicked)
                ))

     def on_move_clicked(self, icon, item):

            if str(item) == "Open GUI":
               icon.stop()
               self.root.deiconify()

            elif str(item) == "Exit":
               icon.stop()
               self.root.destroy()

     def minimize_app(self):
            self.root.withdraw()
            self.icon.run()
        

     def run(self):
         self.root.mainloop()


if __name__ == "__main__":
    app = DesktopBrightnessApp()
    app.run()

Answer 1

当icon.stop(>>执行时,你需要创建新的pystray。缩略语


class DesktopBrightnessApp:
    def __init__(self):
        ...
        # convert img to instance variable self.img
        self.img = ...

        ...
        # create the icon menu once
        self.menu = pystray.Menu(
            pystray.MenuItem("Open GUI", self.on_move_clicked),
            pystray.MenuItem("Exit", self.on_move_clicked)
        )
        # don t create instance of pystray.Icon here

    ...
    def minimize_app(self):
        self.root.withdraw()
        # create instance of pystray.Icon here
        self.icon = pystray.Icon( icon , self.img, menu=self.menu)
        self.icon.run()

    ...
