Setting up OpenGL in Qt

In this recipe, we will learn how to set up OpenGL in Qt.

How to do it…

First, let's create a new Qt widgets application by going to File | New File or Project.
Next, we will remove the mainwindow.ui file because we are not going to use it in this example. Right-click on the mainwindow.ui file and select Remove File from the drop-down menu. Then, a message box will appear and ask for your confirmation. Tick Delete file permanently and press the OK button.
After that, open up your project file (.pro) and add the OpenGL module to your project by adding an opengl keyword behind QT +=, like so:
```
QT += core gui opengl
```
You also need to add another line in your project file so that it will load both the OpenGL and GLu (OpenGL Utilities) libraries during startup. Without these two libraries, you program will not be able to run:
```
LIBS += -lopengl32 -lglu32
```
Then, open up mainwindow.h and remove several things from it:
```
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include &lt...
```
