Dear Rooters,
I found a "killing command" for NX with
Gui.Backend: native this command does not kill NX with: Gui.Backend: qt
[marabou]$ root
** $Id: TGQt.cxx,v 1.32 2006/05/30 07:06:50 antcheva Exp $ this=0xa031e98
...
Now same thing without Qt.
root [0] TCanvas c("cc", "cc", 300, 300) root [1] TCanvas c("cc", "cc", 280, 280)
I tried many cases with the conclusion:
A canvas with Xwidth < 300 crashes NX
Here our NX version:
[marabou]$ rpm -qa | grep nx
nxclient-2.0.0-98 nxserver-2.0.0-76 nxnode-2.0.0-100
Remarks:
- I think this a problem in NX not in ROOT. - Unfortunatly the above case is not the only one. - I didnt have time to study the Qt case systematically(We are an Uni and "students ante portas")
Cheers
Otto
