问题

I\'d just need a quick example on how to easily put an icon with python on my systray. This means: I run the program, no window shows up, just a tray icon (I\'ve got a png file) shows up in the systray and when I right-click on it a menu appears with some options (and when I click on an option, a function is run). Is that possible? I don\'t need any window at all...

Examples / code snippets are REALLY appreciated! :D

For Windows & Gnome

Here ya go! wxPython is the bomb. Adapted from the source of my Feed Notifier application.

import wx

TRAY_TOOLTIP = 'System Tray Demo'
TRAY_ICON = 'icon.png'


def create_menu_item(menu, label, func):
    item = wx.MenuItem(menu, -1, label)
    menu.Bind(wx.EVT_MENU, func, id=item.GetId())
    menu.AppendItem(item)
    return item


class TaskBarIcon(wx.TaskBarIcon):
    def __init__(self):
        super(TaskBarIcon, self).__init__()
        self.set_icon(TRAY_ICON)
        self.Bind(wx.EVT_TASKBAR_LEFT_DOWN, self.on_left_down)

    def CreatePopupMenu(self):
        menu = wx.Menu()
        create_menu_item(menu, 'Say Hello', self.on_hello)
        menu.AppendSeparator()
        create_menu_item(menu, 'Exit', self.on_exit)
        return menu

    def set_icon(self, path):
        icon = wx.IconFromBitmap(wx.Bitmap(path))
        self.SetIcon(icon, TRAY_TOOLTIP)

    def on_left_down(self, event):
        print 'Tray icon was left-clicked.'

    def on_hello(self, event):
        print 'Hello, world!'

    def on_exit(self, event):
        wx.CallAfter(self.Destroy)


def main():
    app = wx.PySimpleApp()
    TaskBarIcon()
    app.MainLoop()


if __name__ == '__main__':
    main()

wx.PySimpleApp deprecated, here's how to use wx.App instead

Took me while to figure this out so I thought I'd share. wx.PySimpleApp is deprecated in wxPython 2.9 and beyond. Here's FogleBird's original script using wx.App instead.

import wx

TRAY_TOOLTIP = 'System Tray Demo'
TRAY_ICON = 'icon.png'

def create_menu_item(menu, label, func):
    item = wx.MenuItem(menu, -1, label)
    menu.Bind(wx.EVT_MENU, func, id=item.GetId())
    menu.AppendItem(item)
    return item

class TaskBarIcon(wx.TaskBarIcon):
    def __init__(self, frame):
        self.frame = frame
        super(TaskBarIcon, self).__init__()
        self.set_icon(TRAY_ICON)
        self.Bind(wx.EVT_TASKBAR_LEFT_DOWN, self.on_left_down)

    def CreatePopupMenu(self):
        menu = wx.Menu()
        create_menu_item(menu, 'Say Hello', self.on_hello)
        menu.AppendSeparator()
        create_menu_item(menu, 'Exit', self.on_exit)
        return menu

    def set_icon(self, path):
        icon = wx.IconFromBitmap(wx.Bitmap(path))
        self.SetIcon(icon, TRAY_TOOLTIP)

    def on_left_down(self, event):
        print 'Tray icon was left-clicked.'

    def on_hello(self, event):
        print 'Hello, world!'

    def on_exit(self, event):
        wx.CallAfter(self.Destroy)
        self.frame.Close()

class App(wx.App):
    def OnInit(self):
        frame=wx.Frame(None)
        self.SetTopWindow(frame)
        TaskBarIcon(frame)
        return True

def main():
    app = App(False)
    app.MainLoop()


if __name__ == '__main__':
    main()

If you can guarantee windows and you do not want to introduce the heavy dependencies of wx, you can do this with the pywin32 extensions.

An alternative if you are trying to run a python based program in the background you can run it as a service. Check out this active state recipe its pretty useful. I believe one of the options is to convert your application to exe with py2exe or pyinstall.

For an example, refer to this thread -> wx question.

wxPython "classic" -> [new API] wxPython 'Phoenix' (Py3)

回答8:

Yes. There is a cross-platform example on wiki.wxpython.org that I've tested with python 2.7 (minconda install) on macOS High Sierra (10.13.3), Windows 7, and gnome 3/centos7. It is here (ignore the page title): https://wiki.wxpython.org/Custom%20Mac%20OsX%20Dock%20Bar%20Icon

Small mods are needed for python 3.6:

you must import wx.adv
wx.TaskBarIcon becomes wx.adv.TaskBarIcon
wx.IconFromBitmap becomes wx.Icon

Gnome 3 required installation of TopIcons Plus.

Since you don't want to have the window display (" no window shows up, just a tray icon"), simply comment out the following line (though you still want to keep the wx.Frame parent):

frame.Show(True)

And since you want to use your own .png icon, remove the WXPdemo image and embeddedimage stuff and replace

icon = self.MakeIcon(WXPdemo.GetImage())

with, for example

icon = wx.Icon('icon.png')

In my experience, this will provide a good start for adapting or extending further.
