Qt_c++ calculator

 Hi , everyone ,  in this  article I'll be showing you  how to make a GUI Calculator using c++ in QT creator.

First of all , open your Qt and creat a new project .

           

Now that your project is created , you will be given the following files by default  :

* calculator pro file :is a list of all source files concerning the project . Those files  contain basic configuration and information .

* mainwindow.h : is the header filefor the main window class

* main.cpp : has our main function which creats our application and shows it 

* mainwindow.cpp : our implementation file

* main window UI file : the visual is a interface file for our GUI 

To sum up: 

 the MainWindow. ui file describes your UI design and MainWindow. h / MainWindow. cpp is the C++ object where you can manipulate the UI with code. ... This macro allows the class to define its own signals/slots and more globally Qt's meta-object system.
