Hi All
I am porting my code from QT3 to QT4. I used QPtrList which allowed me to append items in my list as "void QPtrList::append ( const type * item )". Now what can i do to acheive the same result in QT4. Please help
Thanks alot

Hi JPN
Problem is solved. Thanks alot.
But there are alot alot of modifications required to convert the code from QT3 to QT4.
Is there any simple way to do that. I am thinking of writing all the code again, because modificationa are alot. Please suggest.
Rohit
There is qt3to4 - The Qt 3 to 4 Porting Tool (http://doc.trolltech.com/4.2/qt3to4.html) which is designed to automate the most tedious part of the porting effort.

Hi JPN
I used the tool, it converted also. See the changed example code below
#include <qlayout.h>
#include <Q3WidgetStack>
//Added by qt3to4:
#include <Q3HBoxLayout>
but i am getting error that Q3WidgetStack and Q3HBoxLayout files not present.

To link against the Qt3Support module, add this line to your qmake .pro file:
QT += qt3support
(adds proper include paths too).
