Member Function Documentation

QWidget * QgsTextEditWrapper::createWidget ( QWidget *  parent)
overrideprotectedvirtual

This method should create a new widget with the provided parent.

This will only be called if the form did not already provide a widget, so it is not guaranteed to be called! You should not do initialisation stuff, which also has to be done for custom editor widgets inside this method. Things like filling comboboxes and assigning other data which will also be used to make widgets on forms created in the QtDesigner usable should be assigned in initWidget(QWidget*).

Parameters
parentYou should set this parent on the created widget.
Returns
A new widget

Implements QgsWidgetWrapper.

Definition at line 74 of file qgstexteditwrapper.cpp.

void QgsTextEditWrapper::initWidget ( QWidget *  editor)
overrideprotectedvirtual

This method should initialize the editor widget with runtime data.

Fill your comboboxes here.

Parameters
editorThe widget which will represent this attribute editor in a form.

Reimplemented from QgsWidgetWrapper.

void QgsTextEditWrapper::setValue ( const QVariant &  value)

Definition at line 133 of file qgstexteditwrapper.cpp.

QVariant QgsTextEditWrapper::value ( )
overridevirtual

Will be used to access the widget's value.

Read the value from the widget and return it properly formatted to be saved in the attribute.

If an invalid variant is returned this will be interpreted as no change. Be sure to return a NULL QVariant if it should be set to NULL.

Returns
The current value the widget represents
