Detailed Description

The QFormBuilder class is used to dynamically construct user interfaces from UI files at run-time.

The QFormBuilder class provides a mechanism for dynamically creating user interfaces at run-time, based on UI files created with Qt Designer. 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;

By including the user interface in the example's resources (myForm.qrc), we ensure that it will be present when the example is run:

     <!DOCTYPE RCC><RCC version="1.0">
     <qresource prefix="/forms">

QFormBuilder extends the QAbstractFormBuilder base class with a number of functions that are used to support custom widget plugins:

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 class, found in the QtUiTools module.
