Re: [wxlua-users] wxListCtrl adding item not working in Ubuntu

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

Hi John,
          Thanks for the reply. I created a minimal example (attached and
pasted). This example works fine in windows but doesn't show anything in
Linux. Also another thing I noticed in my original program is that when the
GUI is shown the list Controls in which I have added a lot of elements show
scroll bars also! But no elements are visible.

wx.wxGetApp():MainLoop()
