This class contains context information for attribute editor widgets.
This class should be subclassed for every configurable editor widget type.
Every attribute editor widget needs a factory, which inherits this class.
virtual QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const =0
Override this in your implementation.
virtual unsigned int fieldScore(const QgsVectorLayer *vl, int fieldIdx) const
This method allows disabling this editor widget type for a certain field.
virtual QgsSearchWidgetWrapper * createSearchWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const
By default a simple QgsFilterLineEdit is returned as search widget.
virtual QHash< const char *, int > supportedWidgetTypes()
Returns a list of widget types which this editor widget supports.
virtual QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const =0
Override this in your implementation.
Manages an editor widget Widget and wrapper share the same parent.
Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:90
