Doubt about creating GUI

**foxyproxy** · 6th October 2010, 07:02

You can use both Qt Designer or writing code to develop GUI; maybe if you are a beginner you can try using Qt Designer because it is usually fast and intuitive.
Qt is a cross-platform framework and that means when you write C++ code by using Qt it is compatible on Windows, Linux and Mac. That is ok when you don't write platfotm-dipendent code.

You build the UI with Designer which produces a source file with the UI extension. This file is listed in the FORMS section of your PRO file. It is ultimately compiled by a program called uic to produce a C++ source file called ui_whatever.h that is included in your user interface class implementation, e.g. mainwindow.cpp contains

Qt Code:

Switch view

#include "ui_mainwindow.h"

#include "ui_mainwindow.h"

To copy to clipboard, switch view to plain text mode

which was built from mainwindow.ui.

You don't need to worry about how this works if you let qmake handle it for you. Copy the source to the target platform, run qmake and make. It works happily across Linux, Windows and Mac.

Hi ,
Thanks for your reply , I got confused with your answer which is shown below.

Code:

Switch view

It is ultimately compiled by a program called uic to produce a C++ source file called ui_whatever.h

It is ultimately compiled by a program called uic to produce a C++ source file called ui_whatever.h

To copy to clipboard, switch view to plain text mode

After creating .ui file you asked me to list in forms section of PRO file , after that what all I have to do to get the ui_whatever.h . Actually you told told compile for that what all I have to do.
Please help me .

Sudheer.
