[Qt-interest] (URGENT) Does QT3 Support module is an intermediate step or a real solution the can go into a production release ?

[techsgin]

Hi All, And many thanks in advance :-)

 

Does QT3 Support module is an intermediate step or a real solution that can
go into a production release? 

*In other words is it a gimmick and we must complete the port to a pure QT4
solution to go live?

 

>From looking at QT source code, it looks like that the "Q3Support" layer is
a complete rewriting of the old interface. 

For example Q3MainWindow inherits from QWIdget and not from the old class or
from the QT4 QMainWindow.

This usually means overhead, stability issues, performance issues and lots
of headaches.

 

We really got scared after reading this quote " . This class is part of the
Qt 3 support library. It is provided to keep old source code working. We
strongly advise against using it in new code . ",. :-(

 

We will appreciate anyone's experience is such a dilemma.

 

*Please note that we have read every "Qt Assistant" possible document in
regard, and evaluated the relevant paths.

What are trying to do is to roughly estimate a schedule for feature a
release. 

 

Some extra information about the project: 

* Huge and includes many sub projects.

* The project heavily depends on inheritance of QT objects. (All of them not
just QWidget, this is an infrastructure layer we made) 

* The project extensively relays on the following:

MainWindow, 

Docking,

Canvas,

Custom Drawing,

Custom Widgets,

Custom Plugins,

List Views,

Actions,

Menu, 

Toolbars.

 

 

Many Thanks

TechSgin
