如何使用wxPython添加OSX菜单栏图标

Question

I would like to add an icon to the OSX menu bar at the top of the screen using wxPython. I have tried wx.TaskBarIcon, which adds a System Tray icon in Windows, but this doesn't work - it changes the Dock icon for the app instead. Does anyone know how to do this?

Answer 1

It seems that with wxPython2.9-osx-cocoa-py2.7 you can in fact put up a menubar icon. It looks like you can also call PopupMenu() on TaskBarIcon to attach a menu, which you should be able to use to create a full blown OSX menu bar application.

import wx

class TaskBarFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent, style=wx.FRAME_NO_TASKBAR |
                                              wx.NO_FULL_REPAINT_ON_RESIZE)

        self.tbicon = wx.TaskBarIcon()
        icon = wx.Icon('myicon.ico', wx.BITMAP_TYPE_ICO)
        self.tbicon.SetIcon(icon, '')


app = wx.App(False)
frame = TaskBarFrame(None)
frame.Show(False)
app.MainLoop()

It seems now you can:

just copy and paste the code and run it ;)
