Mouse events in WxPython TaskBarIcon on Mac OSX not triggering

Question

We are using TaskBarIcon WxPython 2.9 on Mac OSX 10.8.5 . We currently have a requirement to capture all Left, Right, and Double Click events when a user clicks on our application's TaskBarIcon. The problem we are facing is that these events do not fire. Any help in this regard will be very noticeable.

This is the code we use.

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() 

NB We do not want to use CreatePopupMenu (because it only starts when left-clicking), instead we want to capture all three of the specified mouse events.

The implementation of the taskbar icon is OS dependent. The following application binds all the events provided in wxPython, so you can use it for testing.

In Windows 7, for example:

• Left Down is emitted with Left Up and more
• The correct shot is emitted correctly
• Click the "Edit" button (the default for Windows is the default).
• Double clicks work just fine

If it doesn't work on OS X or the behavior you get seems wrong for your platform, consider reporting an error at http://trac.wxwidgets.org/ .
