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.


Method Documentation

QFormBuilder.__init__ (self)

Constructs a new form builder.

QFormBuilder.addPluginPath (self, QString pluginPath)

See also setPluginPath() and clearPluginPaths().

QFormBuilder.clearPluginPaths (self)

Clears the list of paths that the form builder uses to search for custom widget plugins.

See also pluginPaths().

unknown-type QFormBuilder.customWidgets (self)

Returns a list of the available plugins.

QStringList QFormBuilder.pluginPaths (self)

Returns the list of paths the form builder searches for plugins.

See also addPluginPath().
