Hi, it's so called as 32000 pix problem which exists in X11, it's known how to be solved. I hope to fix it in next release. Regards. Valeriy. ++ By the way recent modifications of TGListView/TGContainer allows to put more than 100000 browsable items in the container with effective search . I think this is the better alternative for putting "folder" items into TGListTree. Regards, Valeriy ++ The problem is identified and I' m working on it (should be solved soon) ----- Original Message ----- From: "Fons Rademakers" <Fons.Rademakers@cern.ch> To: <gsalo@mrcstl.com> Cc: <roottalk@pcroot.cern.ch> Sent: Tuesday, July 16, 2002 6:19 PM Subject: Re: [ROOT] TGListTree with a large number of items > Hi Glen, > > this is a known and urgent problem.
