Re: [wxlua-users] Key events

[Milind G. <mil...@gm...>]

I see if the panel and frame both have key press events associated I can
catch all keys. So now if I can associate the key press event with all my
sub windows in the frame it should work. I tried the Recursive technique
they have here:  http://wiki.wxwidgets.org/Catching_key_events_globally
using the code:

function connectKeyUpEvent(win)
if win then
win:Connect(wx.wxID_ANY, wx.wxEVT_KEY_UP, CharKeyEvent)
local childNode = win:GetChildren():GetFirst()
while childNode do
connectKeyUpEvent(childNode:GetData())
childNode = childNode:GetNext()
end
end
end

connectKeyUpEvent(frame)

But it creates and error saying unknown method Connect for a type wxObject.
I thought of checking win.Connect if it exists before calling Connect but
that gives the same error during the check itself. I then tried calling
win:Connect using pcall but that gives another error: bad argument#1 to
pcall (value expected)

So right now I am stuck with this method. I will try other methods they
have mentioned.

Thanks,
Milind
