QWidget * createWidget(QWidget *parent) override
This method should create a new widget with the provided parent.
void valueChanged()
Will call the value() method to determine the emitted value.
QVariant value() override
Will be used to access the widget's value.
Manages an editor widget Widget and wrapper share the same parent.
const QgsEditorWidgetConfig config()
Returns the whole config.
void initWidget(QWidget *editor) override
This method should initialize the editor widget with runtime data.
void setValue(const QVariant &value) override
Represents a vector layer which manages a vector based data sets.
