void setConfig(const QVariantMap &config) override
Update the configuration widget to represent the given configuration.
QVariantMap config() override
Create a configuration from the current GUI state.
QgsCheckBoxConfigDlg(QgsVectorLayer *vl, int fieldIdx, QWidget *parent=nullptr)
@ ShowTrueFalse
Shows "True" or "False" strings.
@ ShowStoredValues
Shows actual stored field value.
This class should be subclassed for every configurable editor widget type.
int field()
Returns the field for which this configuration widget applies.
QgsVectorLayer * layer()
Returns the layer for which this configuration widget applies.
void changed()
Emitted when the configuration of the widget is changed.
QVariant::Type type

Definition: qgsfields.cpp:163
Represents a vector layer which manages a vector based data sets.
QgsFields fields() const FINAL
Returns the list of fields of this layer.
