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

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

After digging a bit deeper I find that the items are added to the control
since subsequent calls to InsertItem does detect them but they are not
visible in the GUI. I tried setting the text foreground color also to black
but still nothing. The List Control is created like:

SelList = wx.wxListCtrl(parent, wx.wxID_ANY, wx.wxDefaultPosition,
wx.wxDefaultSize,bit.bor(wx.wxLC_REPORT,wx.wxLC_NO_HEADER))
