void setValue(const QVariant &value) override
QWidget * createWidget(QWidget *parent) override
This method should create a new widget with the provided parent.
QgsValueMapWidgetWrapper(QgsVectorLayer *vl, int fieldIdx, QWidget *editor=0, QWidget *parent=0)
void valueChanged()
Will call the value() method to determine the emitted value.
Manages an editor widget Widget and wrapper share the same parent.
const_iterator constBegin() const
void addItem(const QString &text, const QVariant &userData)
const QgsEditorWidgetConfig config()
Returns the whole config.
const_iterator constEnd() const
QVariant value() override
Will be used to access the widget's value.
QVariant itemData(int index, int role) const
int findData(const QVariant &data, int role, QFlags< Qt::MatchFlag > flags) const
void initWidget(QWidget *editor) override
This method should initialize the editor widget with runtime data.
typedef ConstIterator
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.
