bool valid() override
Return true if the widget has been properly initialized.
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.

bool isChecked() const
const QgsEditorWidgetConfig config()
Returns the whole config.
void initWidget(QWidget *editor) override
This method should initialize the editor widget with runtime data.
bool isChecked() const
void setValue(const QVariant &value) override
bool connect(const QObject *sender, const char *signal, const QObject *receiver, const char *method, Qt::ConnectionType type)
Represents a vector layer which manages a vector based data sets.
