80void QgsKeyValueWidgetWrapper::onValueChanged()
81{
83}
Manages an editor widget Widget and wrapper share the same parent.
static bool isInTable(const QWidget *parent)
Check if the given widget or one of its parent is a QTableView.
void emitValueChanged()
Will call the value() method to determine the emitted value.
QVariant value() const override
Will be used to access the widget's value.
QWidget * createWidget(QWidget *parent) override
This method should create a new widget with the provided parent.
void showIndeterminateState() override
Sets the widget to display in an indeterminate "mixed value" state.
QgsKeyValueWidgetWrapper(QgsVectorLayer *layer, int fieldIdx, QWidget *editor=nullptr, QWidget *parent=nullptr)
Constructor for QgsKeyValueWidgetWrapper.
void initWidget(QWidget *editor) override
This method should initialize the editor widget with runtime data.
bool valid() const override
Returns true if the widget has been properly initialized.
Widget allowing to edit a QVariantMap, using a table.
void setMap(const QVariantMap &map)
Set the initial value of the widget.
void valueChanged()
Emitted each time a key or a value is changed.
Represents a vector layer which manages a vector based data sets.
