A section is a column of a model - if the orientation is horizontal (the default), otherwise a row. - - Every time the current index changes, each widget is updated with data - from the model via the property specified when its mapping was made. - If the user edits the contents of a widget, the changes are read using - the same property and written back to the model. - By default, each widget's \l{Q_PROPERTY()}{user property} is used to - transfer data between the model and the widget. Since Qt 4.3, an - additional addMapping() function enables a named property to be used - instead of the default user property. - - It is possible to set an item delegate to support custom widgets. By default, - a QItemDelegate is used to synchronize the model with the widgets. - - Let us assume that we have an item model named \c{model} with the following contents: - - \table - \row \o 1 \o Qt Norway \o Oslo - \row \o 2 \o Qt Australia \o Brisbane - \row \o 3 \o Qt USA \o Palo Alto - \row \o 4 \o Qt China \o Beijing - \row \o 5 \o Qt Germany \o Berlin - \endtable - - The following code will map the columns of the model to widgets called \c mySpinBox, - \c myLineEdit and \c{myCountryChooser}: - - \snippet doc/src/snippets/code/src_gui_itemviews_qdatawidgetmapper.cpp 0 - - After the call to toFirst(), \c mySpinBox displays the value \c{1}, \c myLineEdit - displays \c{Qt Norway} and \c myCountryChooser displays \c{Oslo}. The - navigational functions toFirst(), toNext(), toPrevious(), toLast() and setCurrentIndex() - can be used to navigate in the model and update the widgets with contents from - the model. - - The setRootIndex() function enables a particular item in a model to be - specified as the root index - children of this item will be mapped to - the relevant widgets in the user interface. - - QDataWidgetMapper supports two submit policies, \c AutoSubmit and \c{ManualSubmit}. - \c AutoSubmit will update the model as soon as the current widget loses focus, - \c ManualSubmit will not update the model unless submit() is called. \c ManualSubmit - is useful when displaying a dialog that lets the user cancel all modifications. - Also, other views that display the model won't update until the user finishes - all their modifications and submits. - - Note that QDataWidgetMapper keeps track of external modifications. If the contents - of the model are updated in another module of the application, the widgets are - updated as well. - - \sa QAbstractItemModel, QAbstractItemDelegate - */ - -/*! \enum QDataWidgetMapper::SubmitPolicy - - This enum describes the possible submit policies a QDataWidgetMapper - supports. - - \value AutoSubmit Whenever a widget loses focus, the widget's current - value is set to the item model. - \value ManualSubmit The model is not updated until submit() is called. - */ - -/*! - \fn void QDataWidgetMapper::currentIndexChanged(int index) - - This signal is emitted after the current index has changed and - all widgets were populated with new data. \a index is the new - current index. - - \sa currentIndex(), setCurrentIndex() - */ - -/*! - Constructs a new QDataWidgetMapper with parent object \a parent. - By default, the orientation is horizontal and the submit policy - is \c{AutoSubmit}. - - \sa setOrientation(), setSubmitPolicy() - */ -QDataWidgetMapper::QDataWidgetMapper(QObject *parent) - : QObject(*new QDataWidgetMapperPrivate, parent) -{ - setItemDelegate(new QItemDelegate(this)); -} - -/*! - Destroys the object. - */ -QDataWidgetMapper::~QDataWidgetMapper() -{ -} - -/*! - Sets the current model to \a model.
