Question

我想将应用程序运行保留在后台，即使它的所有 windows 都已关闭。有没有功能或东西可以做到这一点？我找不到关于 SO 的答案。这是我的代码：

import gi
import sys

gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

class App(Gtk.Application):
    """The application manager."""

    def __init__(self, *args, **kwargs):
        Gtk.Application.__init__(
            self,
            *args,
            application_id="org.app_test",
            # flags=Gio.ApplicationFlags.HANDLES_COMMAND_LINE,
            **kwargs
        )

        # We are only allowed to have one window
        self.window = None

    def do_activate(self):
        """Activate the app."""

        # Create the window, if it does not exist
        if self.window is None:
            self.window = AppWindow(application=self, title="MusicApp", name="0")
            self.window.present()

    def do_startup(self):
        """Start the app."""
        Gtk.Application.do_startup(self)

class AppWindow(Gtk.ApplicationWindow):
    """The main window for the application."""

    def __init__(self, *args, application, **kwargs):
        Gtk.ApplicationWindow.__init__(
            self,
            *args,
            application=application,
            **kwargs
        )

        # The application
        self.app = application

        self.show_all()

if __name__ == "__main__":
    app = App()
    app.run(sys.argv)

当我关闭 window 时，程序停止。即使所有 windows 都已关闭，我如何让它继续运行？

Answer 1

您可以使用 my_app.hold() 让应用程序认为有一个额外的 window 打开，然后当 window 关闭时不会关闭应用程序，因为它认为还有另一个不存在 window 打开。
