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");
     file.open(QFile::ReadOnly);
     QWidget *myWidget = builder.load(&file, this);
     file.close();

     QVBoxLayout *layout = new QVBoxLayout;
     layout->addWidget(myWidget);
     setLayout(layout);
 }

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.
