It shouldn't be nil , maybe a typo. This code shows the popup menu for
a right down mouse event with control down and for positioning below a
button. Again, if you can provide the simplest full example of some
code I would appreciate it since I wouldn't have to write it from
scratch.

function main()
    frame=3Dwx.wxFrame(wx.wxNull,-1,"Frame",wx.wxDefaultPosition,wx.wxSize(=
400,400))

    popMenu =3D wx.wxMenu()
    popMenu:Append(11, "Menu Item")
   =20
    panel =3D wx.wxPanel(frame, -1)
   =20
    textCtrl =3D wx.wxTextCtrl(panel, -1, "", wx.wxPoint(5,5),
wx.wxSize(300, 200))
    function textRightDown(event)
        if (event:ControlDown()) then=20
            textCtrl:PopupMenu(popMenu, event:GetPosition())
        end
    end
    textCtrl:ConnectEvent(-1, wx.wxEVT_RIGHT_DOWN, textRightDown)
   =20
    button =3D wx.wxButton(panel, 12, "Button", wx.wxPoint(5, 210))
    function buttonDown(event)
        local width, height =3D button:GetSize()
        button:PopupMenuXY(popMenu, 0, height)
        event:Skip()
    end
    button:ConnectEvent(12, wx.wxEVT_COMMAND_BUTTON_CLICKED, buttonDown)
=20
    frame:Centre()
    frame:Show(wx.TRUE)
end

main()

 Google. This is like shooting at a tiny hole in a distant wall, while wear=

The docs, for now, are the Import/*.i files in the source code
download. Look through them to see what is wrapped and what isn't. It
should mostly follow the wxWidgets manual. I think in the future we
can try to make it compatible to wxPython since wxLua has similiar
constraints and functions need to be reworked in similiar ways. (eg.
you can't return values from the input to functions, like
wxWindow::GetSize(int *width, int *height), but rather return both of
them as shown in the code above.)
