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.

QWidget * QAbstractFormBuilder::load ( QIODevice * device, QWidget * parent = 0 )   [virtual]

Loads an XML representation of a widget from the given device, and constructs a new widget with the specified parent.

See also save().

void QAbstractFormBuilder::save ( QIODevice * device, QWidget * widget )   [virtual]

Saves an XML representation of the given widget to the specified device in the standard UI file format.

See also load().

void QAbstractFormBuilder::setWorkingDirectory ( const QDir & directory )
