Mac OSX上的WxPython TaskBarIcon的鼠标事件未触发

我们在Mac OSX 10.8.5上使用Wx Python 2.9的TaskBarIcon,目前我们需要在用户点击Application的TaskBarIcon时获取所有Left,Right和Double Click事件.我们遇到的问题是这些事件没有被触发.在这方面的任何帮助都会非常明显.

这是我们使用的代码

import os
import sys
import wx

__author__ = 'Ammar Hasan'

CURRENT_ABSOLUTE_PATH = os.path.dirname(sys.argv[0])
TRAY_ICON = CURRENT_ABSOLUTE_PATH + "/resources/task_icon.ico"
TRAY_ICON_TOOLTIP = "UI Application"


ID_SHOW_OPTION = wx.NewId()
ID_EDIT_OPTION = wx.NewId()
ID_EXIT_OPTION = wx.ID_EXIT


class Icon(wx.TaskBarIcon):

    def __init__(self, parent, icon, tooltip):
        super(Icon, self).__init__(iconType=wx.TBI_CUSTOM_STATUSITEM)
        self.set_icon(icon, tooltip)
        self.parent = parent
        self.Bind(wx.EVT_TASKBAR_LEFT_DOWN, self.on_icon_click)
        self.Bind(wx.EVT_TASKBAR_RIGHT_DOWN, self.on_icon_click)
        self.Bind(wx.EVT_MENU, self.menu_item_click)

    def get_menu(self):
        menu = wx.Menu()
        menu.Append(ID_SHOW_OPTION, "&Show Option 1")
        menu.Append(ID_EDIT_OPTION, "&Edit Option 2")
        menu.AppendSeparator()
        menu.Append(ID_EXIT_OPTION, "E&xit")
        return menu

    def on_icon_click(self, event):
        if event:
            print "Event Triggered."
        menu = self.get_menu()
        self.PopupMenu(menu)

    def menu_item_click(self, event):
        if event.Id == ID_SHOW_OPTION:
            pass
        elif event.Id == ID_EDIT_OPTION:
            pass
        else:
            self.parent.quit()

    def make_icon(self, img):
        """
        The various platforms have different requirements for the
        icon size...
        """
        if "wxMSW" in wx.PlatformInfo:
            img = img.Scale(16, 16)
        elif "wxGTK" in wx.PlatformInfo:
            img = img.Scale(22, 22)
        # wxMac can be any size upto 128x128, so leave the source img alone....
        icon = wx.IconFromBitmap(img.ConvertToBitmap())
        return icon

    def set_icon(self, path, tool_tip):
        image = wx.Image(path)
        icon = self.make_icon(image)
        self.SetIcon(icon, tool_tip)

    # def CreatePopupMenu(self, event=None):
    #     self.on_icon_click(event)


class Frame(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(Frame, self).__init__(*args, **kwargs)
        self.app = wx.GetApp()
        self.icon = Icon(self, TRAY_ICON, TRAY_ICON_TOOLTIP)

    def quit(self):
        self.app.ExitMainLoop()

if __name__ == "__main__":
    app = wx.App()
    frame = Frame(None)
    frame.Show(False)
    app.SetTopWindow(frame)
    app.MainLoop()

注:我们不想使用CreatePopupMenu(因为它只在Left Click上触发),而是我们想要抓取所有三个指定的鼠标事件.

任务栏图标实现取决于操作系统.以下应用程序绑定wxPython中提供的所有事件,以便您可以使用它进行测试.

在Windows 7上,例如:

>左下方与左上方一起发射而不是单独发射
>右下方正确发射
>右键向上发出单击(Windows默认为菜单)
>双击工作正常

如果它在OS X上不起作用,或者您的平台上的行为似乎有问题,请考虑在http://trac.wxwidgets.org/报告错误.
