| typedef QgsActionManager QgsAttributeAction |
QgsAttributeAction is deprecated and has been replaced with QgsActionManager.
This legacy typedef will be removed with QGIS 3.

| typedef QVariantMap QgsEditorWidgetConfig |
Holds a set of configuration parameters for a editor widget wrapper.
It's basically a set of key => value pairs.
If you need more advanced structures than a simple key => value pair, you can use a value to hold any structure a QVariant can handle (and that's about anything you get through your compiler)
These are the user configurable options in the field properties tab of the vector layer properties. They are saved in the project file per layer and field. You get these passed, for every new widget wrapper.

| typedef QList< QPair< QColor, QString > > QgsNamedColorList |
List of colors paired with a friendly display name identifying the color.
Definition at line 30 of file qgscolorscheme.h.
| typedef QMultiMap<QString, QString> QgsSmartConditionMap |
A multimap to hold the smart group conditions as constraint and parameter pairs.
Both the key and the value of the map are QString. The key is the constraint of the condition and the value is the parameter which is applied for the constraint.
The supported constraints are: tag -> symbol has the tag matching the parameter !tag -> symbol doesnot have the tag matching the parameter group -> symbol belongs to group specified by the parameter !group -> symbol doesn't belong to the group specified by the parameter name -> symbol has a part of its name matching the parameter !name -> symbol doesn't have any part of the name matching the parameter
Example Usage: QgsSmartConditionMap conditions; conditions.insert( "tag", "red" ); // adds the condition: Symbol has the tag red conditions.insert( "!name", "way" ); // add the condition: Symbol doesn't have any part of its name matching way
