This is kinda' hard to read. :/

Take the choices.wx.lua sample, add the line to the leave window.

 frame:SetStatusText("wxEvents from contols will be displayed here", 0)
 frame:Connect(wx.wxEVT_LEAVE_WINDOW, function(event) print("Hi") end)

It works for me. Remember that the frame is mostly hidden by the
notebook so you have to find a spot where it's exposed. Try it out for
the listbox as well.

Yes the EVT_LEAVE_WINDOW( test::OnLeaveWindow ) is similar to
wxEvtHandler::Connect. There are some differences however. The Connect
function uses a dynamic event table that is processed before (IIRC)
the static event table generated with the macro so you have to use
event:Skip() to get the default processing to work in some cases.
