Re: [osg-users] osgSim::ScalarBar: supporting the osgText::String title;
Hi Xiadon,
And so to a *third* request... Please could you send the files you
have modified as a separate attachment, inlined submission cannot be
handled as the mail tools breaks the formatting.
Robert.

HI Xiadong,
I'm not sure what you intend from this email. Is it a code
submission? If so could you please post it to osg-submissions and
make sure the files are not inlined in the email itself. zipping the
files is an easy workaround to mailer bugs that inline text files.
Robert.

[osg-users] osgSim::ScalarBar: supporting the osgText::String title;
Hi.
I try to update the class osgSim::ScalarBar to support for the
osgText::String title.
it may be very simple. but I hope i can do something to OSG.
Thanks.
