This is done by including the following declaration in a qmake project +file to ensure that the application is compiled and linked appropriately. A form loader object, +provided by the QUiLoader class, is used to construct the user interface. This user interface +can be retrieved from any QIODevice; for example, a QFile object can be used to obtain a form +stored in a project's resources. The QUiLoader::load() function takes the user interface +description contained in the file and constructs the form widget.
