4 Working with Qt Creator
In this section we learn how to work with Qt Creator. The Qt framework provides tools to
develop graphical user interfaces. With the help of an example project we show how to
compile your own Qt based programs and automatically transfer them to the target.
4.1 Stop the Running Qt Demo on the Target
A Qt demo application starts automatically by default after the target has booted
completely.
Qt provided by Digia is very commonly used for embedded systems and it is
supported by this BSP. Please visit http://www.qt.io in order to get all the
documentation that is available about this powerful cross-pl
atform GUI
toolkit.
Some demos that show the capabilities of Qt version 5.3.2 are included in
the BSP.
Before we start compiling and running our example project out of Qt Creator we must first
close this Qt application.
 Open a serial connection with Microcom.
 After the target is booted login with root and enter the following command to stop the
Qt applicat
ion:
 systemctlstopqt5demo
After the Qt demo is stopped with the command above we can start to use Qt Creator.
If you want to remove the qt5demo from the autostart enter the following
command:
systemctldisableqt5demo
4.2 Importing the Demo Application
We start with opening the Qt Creator in a terminal, because otherwise the correct
environment of the toolchain is not set.
