QgsMapCanvas
Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:89
QgsSearchWidgetWrapper
Shows a search widget on a filter form.
Definition: qgssearchwidgetwrapper.h:85
QgsEditorWidgetFactory::create
virtual QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const =0
Override this in your implementation.
QgsEditorWidgetFactory::configWidget
virtual QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const =0
Override this in your implementation.
QgsEditorWidgetWrapper
Manages an editor widget Widget and wrapper share the same parent.
