# QtUiTools Module

The QtUiTools module provides classes to handle forms created with Qt Designer. These forms are processed at run-time to produce dynamically-generated user interfaces. In order to generate a form at run-time, a resource file containing a `.ui` file is needed. Applications that use the form handling classes need to be configured to be built against the QtUiTools module. This is done by including the following declaration in a `qmake` project file to ensure that the application is compiled and linked appropriately.

            CONFIG += uitools

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.

To include the definitions of the module's classes, use the following directive:

            #include <QtUiTools>
