I'm trying to set up a global keyboard shortcut for my application.  I know
how to do this by associating the shortcut with a menu item, but I want to
do it without a corresponding menu item.  As per the instructions here (
http://lists.wxwidgets.org/pipermail/wxpython-users/2003-August/021655.html),
I should be able to do this with an accelerator table, but I can't get it to
work.

I've included a small, self-contained sample that attempts to bind an event
handler with the Ctrl-L shortcut.  Can anybody see what I'm doing wrong?
Thanks in advance.

I am running wxPython 2.8.8.1 on Ubuntu 8.04.1 Hardy.
---------------------------------------------------------------------
import wx

class MainWindow(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__ (self, parent, -1, title, size=(500,200))
        self.panel = wx.Panel(self, -1)

    EVT_TEST_ID = wx.NewId()

    wx.EVT_MENU(self, EVT_TEST_ID, self.OnTestEvent)

    aTable = wx.AcceleratorTable([
        (wx.ACCEL_CTRL, ord('L'), EVT_TEST_ID)
    ])

    self.SetAcceleratorTable(aTable)

    self.Show(True)

    def OnTestEvent(self, event):
        print "OnTestEvent fired"

app = wx.App()
frame = MainWindow(None, -1, "Test")
app.MainLoop()

Hmmm...this works on Windows XP, '2.8.7.1 (msw-unicode)', Python 2.5.2.

Try changing the event binding to this instead:

self.Bind(wx.EVT_MENU, self.OnTestEvent, id=EVT_TEST_ID)

That's the way I was told to do it...by Robin, I think.

Thanks for the response Mike.  Unfortunately, the alternative syntax doesn't
work for me either.

???

I loaded Ubuntu Hardy in my VM and confirmed that it does not work with your
sample code. Weird. I did find a recipe in the wiki that might work for you:

http://wiki.wxpython.org/Using%20Multi-key%20Shortcuts

It's a little bit above my head, but it seems to be using an alternative
technique. Maybe it can be modified to work for you?

Try adding a widget to the frame that can have the keyboard focus.  The
focus needs to be on some widget within the frame for accelerators attached
to the frame to be active.

I tried adding a button to the panel, and giving the button focus, and now
the accelerator table is working as expected.

Thanks Mike and Robin, for your prompt and helpful responses.
