This demonstration will illustrate how to create a new project from scratch for the ComfilePi. In this demonstration Qt Quick will be used over Qt Widgets. Qt Quick is a better choice for more modern GUIs.
Open the project file, QtQuickDemo.pro, and edit the target.path
as shown below to change the deploy location to the user's home directory.
# Default rules for deployment. target.path = $${TARGET}/bin INSTALLS += target
Then select the debug icon from the left toobar to deploy the project, execute it, and begin a debugging session.
To learn more about Qt Quick development, see Qt's official documentation.
