Hi Burak, I never though about these things. I think that qooxdoo is smart enough to make lazy instantiation of widgets fast. I'm working in JS a lot (not only with qooxdoo, I'm also doing on one arcade game) and my experiences are that the biggest performance problems are caused by DOM. I can make nearly unlimited function calls, but when it goes to DOM I'm really careful.
I think that qooxdoo is fast enough, but <canvas> rendering in some cases and decreasing of dom elements can increase performance a lot. I'm looking forward to see <canvas> in table and virtual widgets rendering;-) -- Best regards - Petr Kobalicek <http://kobalicek.com> 2009/10/16 Burak Arslan <burak.ars...@arskom.com.tr>: > Petr Kobalíček wrote: >> I think that you shouldn't worry about function calls.
