2.2 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.
2.2.1 Stop the Running Qt Demo on the Target
A Qt demo application starts automatically by default after the target has booted
completely ( section 3.2.14 ). Before we start compiling and running our example project
out of Qt Creator we must first close this Qt application.
ƒ
Open a serial connection with Microcom.
ƒ
After the target is booted login with root and enter the following command to stop the
Qt application:
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
2.2.2 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.
ƒ
Open a terminal.
ƒ
Enter the following command in the terminal to start Qt Creator
/usr/bin/qtcreator.sh &
