RE: [ROOT] QtROOT Release v2.3 (GSI)

Hi Valeri,

We are using the Qt free edition only! and we have a very good experience
with it.

In fact we started with Qt v2.3 (Free Edition), then we start using the beta
of versions of Qt 3.0. (1 to 6)

Qt 3.0 is very attractive for several reasons: 

	1. It is possible to edit the slots inside or outside the designer. 
The fact that you can add your own methods (slots) to the Widget
(MyWidget.ui.h) as cpp methods directly make it more powerful than the old
technique in Qt v2.3, where you have to subclass from the Widget in order to
add your own functionality (which is also supported in Qt 3.0).
	2. The Qt 3.0 Designer is a powerful tool, with a powerful text
editor, you can see the features your self on:
		http://doc.trolltech.com/3.0/designer-manual.html

	3. I found the qmake utility is a much powerful and easy to use tool
compared to the tmake utility in Qt 2.3

	4. Creating projects within the designer make it easier to maintain
your software, in other words, the effort needed to take care of few lines
of code in the project file is not comparable to that of maintaining
Makefiles!



regards 


Mohammad

  I ahve very simple question:

  What Qt edition are you using yourself: commercial or free one ?

  My guess you yourself bought Qt and use the commercial version.
  Have you any experience with Qt Free Edition v.3.0 (for Linux) ?

                Thank you, Valeri
