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

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

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">
        <file>mywidget.ui</file>
     </qresource>
     </RCC>

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.
