QRect is a class in the Qt framework, which is a cross-platform application development framework written in C++. It provides a simple API to handle graphical user interfaces (GUI) and other low-level tasks, making it easier to develop software quickly and efficiently.

The QRect width property allows you to retrieve the width of a rectangle. Here are some code examples that demonstrate how to use this property:

Example 1: Retrieving the width of a QRect object

#include 

int main()
{
    QRect rect(0, 0, 100, 100);   // create a QRect object with a width of 100
    int width = rect.width();     // retrieve the width of the QRect object

    return 0;
}

Example 2: Setting the width of a QRect object

#include 

int main()
{
    QRect rect(0, 0, 100, 100);   // create a QRect object with a width of 100
    rect.setWidth(200);           // set the width of the QRect object to 200

    return 0;
}

In both examples, the QRect class is included with the `#include ` statement. Therefore, the QtCore library package is needed.
