Can I create a wxPython tray icon application without the Python icon appearing in the Dock?

问题

Here is the slightly modified source code for an example tray icon application I found on SO:

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)

class App(wx.App):
    def OnInit(self):
        self.SetTopWindow(wx.Frame(None, -1))
        TaskBarIcon()

        return True

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

if __name__ == '__main__':
    main()

It shows a tray icon successfully, and indeed shows no Frame, but it does show the Python icon in the Dock. I assume it will also show a Python icon in the Windows task bar. How do I stop that from happening?

I'm using wxPython 2.9 on Python 2.7 on OSX Mountain Lion

You should create a bundle from Your application and tell specify that your app is kind of "background", so it shall not show icon in dock.

To do this, You have to following property to Your bundle property file (Info.plist).

<key>LSUIElement</key>
<string>1</string>

See following articles:
