1 These forms are processed at run-time to produce dynamically-generated user interfaces. 

     2 In order to generate a form at run-time, a resource file containing a UI file is needed. 

     3 Applications that use the form handling classes need to be configured to be built against 

     4 the QtUiTools module. This is done by including the following declaration in a qmake project 

     5 file to ensure that the application is compiled and linked appropriately. A form loader object, 

     6 provided by the QUiLoader class, is used to construct the user interface. This user interface 

     7 can be retrieved from any QIODevice; for example, a QFile object can be used to obtain a form 

     8 stored in a project's resources. The QUiLoader::load() function takes the user interface 

     9 description contained in the file and constructs the form widget.
