wxPython TaskbarIcon菜单崩溃

Question

右键单击系统托盘图标时，以下代码将崩溃。它不会产生任何错误（除了一个我无法理解的复杂错误代码），所以我很难跟踪问题。你知道吗

import wx
import wx.adv

class TaskbarIcon(wx.adv.TaskBarIcon):
    def __init__(self, frame):
        self.frame = frame
        super(TaskbarIcon, self).__init__()
        self.SetIcon(wx.Icon(wx.IconLocation("fav.ico")), "TestApp")
        self.Bind(wx.adv.EVT_TASKBAR_LEFT_DOWN, self.OnRunNow)

    def CreatePopupMenu(self):
        menu = wx.Menu()
        run_now_item = menu.Append(-1, "Run now...", "Run now.")
        menu.AppendSeparator()
        exit_item = menu.Append(wx.ID_EXIT)
        self.Bind(wx.EVT_MENU, self.RunNow, run_now_item)
        self.Bind(wx.EVT_MENU, self.OnExit, exit_item)
        return menu

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

    def OnRunNow(self, event):
        self.ShowBalloon("Test", "Content", 5000)

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

if __name__ == '__main__':
    app = App()
    app.MainLoop()

我认为你的问题在于你如何约束你的事件。试试这个

import wx.adv
import wx

# Note NewId has been deprecated since wx version 4.0.1 and replaced by wx.NewIdRef
ID_RUN = wx.NewIdRef()
ID_EXIT = wx.NewIdRef()


class TaskBarIcon(wx.adv.TaskBarIcon):
    def __init__(self, frame):
        self.frame = frame
        super(TaskBarIcon, self).__init__()
        self.SetIcon(wx.Icon(wx.IconLocation("fav.ico")), "TestApp")
        self.Bind(wx.adv.EVT_TASKBAR_LEFT_DOWN, self.on_left_down)

    def CreatePopupMenu(self):
        menu = wx.Menu()
        menu.Append(ID_RUN, "Run now...")
        menu.AppendSeparator()
        menu.Append(ID_EXIT, "Exit")

        menu.Bind(wx.EVT_MENU, self.OnRunNow, id=ID_RUN)

        menu.Bind(wx.EVT_MENU, self.OnExit, id=ID_EXIT)

        return menu


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

    def OnRunNow(self, event):
        #Note: ShowBalloon is only available under Windows OS
        #self.ShowBalloon("Test", "Content", 5000)
        wx.MessageBox("Test", "Content")

    def OnExit(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()

桑妮·奇迪的回答把我引向了实际问题。在RunNow和OnRunNow之间存在一些不一致的命名。解决这个问题可以解决它。你知道吗
