    \class QAbstractFormBuilder

    \brief The QAbstractFormBuilder class provides a default
    implementation for classes that create user interfaces at
    run-time.

    \inmodule QtDesigner

    QAbstractFormBuilder provides a standard interface and a default
    implementation for constructing forms from user interface
    files. It is not intended to be instantiated directly. Use the
    QFormBuilder class to create user interfaces from UI files at
    run-time. For example:

    \snippet doc/src/snippets/code/tools_designer_src_lib_uilib_abstractformbuilder.cpp 0

    To override certain aspects of the form builder's behavior,
    subclass QAbstractFormBuilder and reimplement the relevant virtual
    functions:

    \list
    \o load() handles reading of UI format files from arbitrary
       QIODevices, and construction of widgets from the XML data
       that they contain.
    \o save() handles saving of widget details in UI format to
       arbitrary QIODevices.
    \o workingDirectory() and setWorkingDirectory() control the
       directory in which forms are held. The form builder looks for
       other resources on paths relative to this directory.
    \endlist

    The QFormBuilder class is typically used by custom components and
    applications that embed \QD. Standalone applications that need to
    dynamically generate user interfaces at run-time use the
    QUiLoader, found in the QtUiTools module.
