On my machine, Draw.Begin with gb.gtk takes about 120 micro-seconds the first time it is called, 50 us the next times. With gb.qt4, it takes about 300 us each time. So I don't understand how it could take 20 ms on your machine: it means that my PC is 66x faster than yours! -- Benoît Minisini ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
