Detailed Description

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

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:

         MyForm::MyForm(QWidget *parent)
             : QWidget(parent)
             QFormBuilder builder;
             QFile file(":/forms/myWidget.ui");
             QWidget *myWidget = builder.load(&file, this);

             QVBoxLayout *layout = new QVBoxLayout;

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

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