Manages an editor widget Widget and wrapper share the same parent.
This class should be subclassed for every configurable editor widget type.
Manages an editor widget Widget and wrapper share the same parent.
Every attribute editor widget needs a factory, which inherits this class.
bool supportsField(const QgsVectorLayer *vl, int fieldIdx)
Check if this editor widget type supports a certain field.
virtual QHash< const char *, int > supportedWidgetTypes()
Returns a list of widget types which this editor widget supports.
Represents a vector layer which manages a vector based data sets.
