After creating the widget you can + use QObject::child() and QObject::queryList() to access child + widgets of this returned widget. + + \i Adding additional widget factories to be able to create custom + widgets. See createWidget() for details. + + \endlist + + This class is not included in the Qt library itself. To use it you + must link against \c libqui.so (Unix) or \c qui.lib (Windows), which is + built into \c INSTALL/lib if you built \e{Qt Designer} (\c INSTALL is + the directory where Qt is installed ). + + If you create a QMainWindow using a QWidgetFactory, be aware that + it already has a central widget. Therefore, you need to delete this + one before setting another one. + + See the "Creating Dynamic Dialogs from .ui Files" section of the \link + designer-manual.book Qt Designer manual\endlink for an example.
