wxpython 窗口图标和托盘图标

import wxclass App(wx.App):    def OnInit(self):        frame = wx.Frame(parent=None, title='Bare')        frame.Show()        icon=wx.EmptyIcon()        icon.LoadFile("loadIcon.ico",wx.BITMAP_TYPE_ICO)        frame.SetIcon(icon)        frame.tbicon=wx.TaskBarIcon()        frame.tbicon.SetIcon(icon,"wxPython Demo")        return Trueapp = App()app.MainLoop()

这里有个问题：托盘图标只是显示出来了，并没有响应任何事件。继续研究。

续：找到完整的托盘程序

import wxclass TaskBarIcon(wx.TaskBarIcon):    ID_Hello = wx.NewId()    def __init__(self, frame):        wx.TaskBarIcon.__init__(self)        self.frame = frame        self.SetIcon(wx.Icon(name='loadIcon.ico', type=wx.BITMAP_TYPE_ICO), 'TaskBarIcon!')        self.Bind(wx.EVT_TASKBAR_LEFT_DCLICK, self.OnTaskBarLeftDClick)        self.Bind(wx.EVT_MENU, self.OnHello, id=self.ID_Hello)    def OnTaskBarLeftDClick(self, event):        if self.frame.IsIconized():            self.frame.Iconize(False)        if not self.frame.IsShown():            self.frame.Show(True)            self.frame.Raise()    def OnHello(self, event):         wx.MessageBox('Hello From TaskBarIcon!', 'Prompt')# override    def CreatePopupMenu(self):         menu = wx.Menu()         menu.Append(self.ID_Hello, 'Hello')         return menuclass Frame(wx.Frame):    def __init__(        self, parent=None, id=wx.ID_ANY, title='TaskBarIcon', pos=wx.DefaultPosition,        size=wx.DefaultSize, style=wx.DEFAULT_FRAME_STYLE):        wx.Frame.__init__(self, parent, id, title, pos, size, style)# wx.Frame.SetIcon(wx.Icon('Wand.ico', wx.BITMAP_TYPE_ICO))# The above line is invalid: method become callable after bounding to the instance        self.SetIcon(wx.Icon('loadIcon.ico', wx.BITMAP_TYPE_ICO))        panel = wx.Panel(self, wx.ID_ANY)        button = wx.Button(panel, wx.ID_ANY, 'Hide Frame', pos=(60, 60))        self.Bind(wx.EVT_BUTTON, self.OnHide, button)# button = wx.Button(panel, wx.ID_ANY, 'Close', pos=(60, 100))# self.Bind(wx.EVT_BUTTON, self.OnClose, button)        self.Bind(wx.EVT_CLOSE, self.OnClose)        self.Bind(wx.EVT_ICONIZE, self.OnIconfiy) # What is the meaning?        self.taskBarIcon = TaskBarIcon(self)        sizer = wx.BoxSizer()        sizer.Add(button, 0)        panel.SetSizer(sizer)    def OnHide(self, event):        self.Hide()    def OnIconfiy(self, event):        wx.MessageBox('Frame has been iconized!', 'Prompt')        event.Skip()    def OnClose(self, event):        self.taskBarIcon.Destroy()        self.Destroy()def TestFrame():    app = wx.PySimpleApp()    frame = Frame(size=(640, 480))    frame.Centre()    frame.Show()    app.MainLoop()if __name__ == '__main__':    TestFrame()

另外一种方式：（推荐用第一种方法）

# -*- coding: UTF-8 -*-import wxfrom wx import Frameclass MyFrame(Frame):    def __init__(self, parent, id, title):        Frame.__init__(self, parent, id, title)        self.Bind(wx.EVT_MOVE, self.OnMove)        self.Bind(wx.EVT_SIZE, self.OnSize)        icon = wx.EmptyIcon()        icon.CopyFromBitmap(wx.BitmapFromImage(wx.Image(("katon.png"), wx.BITMAP_TYPE_PNG)))        self.SetIcon(icon)    def OnSize(self, event):        size = event.GetSize()        print "size:", size.width, size.height    def OnMove(self, event):        pos = event.GetPosition()        print "pos:", pos.x, pos.yclass MyApp(wx.App):    def OnInit(self):        frame = MyFrame(None, -1, u"测试")        frame.Show(True)        self.SetTopWindow(frame)        return Truedef main():    app = MyApp(0)    app.MainLoop()if __name__ == "__main__":    main()

此种方法的png图片只能是32X32的，否则会加载不成功。
