Qt4.2.3

[Sheetal]

hi...
i have written my application using QT3.1 version.
Now i want to run the same application on QT 4.2.3. Do i need to make any changes in the code????

Can anyone reply urgently

Qt has changed drastically from 3.x. There is a porting tool, however.
But you will have to port a lot of code by hand.
Look at "qt3to4 - The Qt 3 to 4 Porting Tool" section in Qt Assistant.

Yes, you do have to make changes. See Porting from Qt 3 to Qt 4.
