This method should create a new widget with the provided parent.
void valueChanged()
Will call the value() method to determine the emitted value.
QgsField field() const
Access the field.
Manages an editor widget Widget and wrapper share the same parent.
void showIndeterminateState() override
Sets the widget to display in an indeterminate "mixed value" state.
QVariantMap config() const
Returns the whole config.
bool valid() const override
Return true if the widget has been properly initialized.
QVariant value() const override
Will be used to access the widget&#39;s value.
void initWidget(QWidget *editor) override
This method should initialize the editor widget with runtime data.
QgsCheckboxWidgetWrapper(QgsVectorLayer *vl, int fieldIdx, QWidget *editor=nullptr, QWidget *parent=nullptr)
QgsSignalBlocker< Object > whileBlocking(Object *object)
Temporarily blocks signals from a QObject while calling a single method from the object.
