I found this toturial http://doc.trolltech.com/3.3/tutorial1-01.html I try to compile it (I work with eclipse) and I get error that I dont understand what to do I gat error for every kine in the main: undefind reference to 'QString::shared_null.... . . undefind reference to 'QApplication::QApplication(int&,char **)' ... and so on...
I think that it something with the configure of the build? do you know what I need to do? thanks NB On 11/16/06, Robert Osfield <[EMAIL PROTECTED]> wrote:

I haven't seen this, but it sounds like the timer has been given a lower priority or simply implemented differently. Using GUI timers to drive redraws isn't ideal, for solid framerates you really need to run a separate graphics thread. For any serious vis-sim work this is essential. For interactive apps GUI timers will often suffice, but as you've found out you are at the mercy of the Windowing toolkits implementation of its timers.
