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.


Method Documentation

QAbstractFormBuilder.__init__ (self)

Constructs a new form builder.

QWidget QAbstractFormBuilder.load (self, QIODevice device, QWidget parent = None)

The parent argument, if not None, causes self to be owned by Qt instead of PyQt.

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

See also save().

QAbstractFormBuilder.save (self, QIODevice dev, QWidget widget)

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

See also load().

QAbstractFormBuilder.setWorkingDirectory (self, QDir directory)

Sets the current working directory of the form builder to the specified directory.

See also workingDirectory().

QDir QAbstractFormBuilder.workingDirectory (self)

Returns the current working directory of the form builder.

See also setWorkingDirectory().
