No problem, Biplab! Thanks for your time and fast reaction! But it's your quotation:
"It's worth mentioning though that Qt comes with special styles for Mac OS X and Windows XP that use native APIs (Appeareance Manager on Mac OS X, UxTheme on Windows XP) for drawing standard widget primitives (e.g. scrollbars or buttons) exactly like any native application."
And how do you think, will trolls from trolltech continue develop and upgrade their library for speed, visual style and so on? I certainly think they will!
i will definitely find out all accessible information about wx and perhaps change my opinion about it's usefulness, but now i firmly believe that Qt is easier and "righteouser"!
BTW, very useful thing for each wxWidgets developer:
