Typedef Documentation

ContactList

typedef QList< QgsAbstractMetadataBase::Contact > QgsAbstractMetadataBase::ContactList

A list of contacts.

Since

QGIS 3.2

Definition at line 199 of file qgsabstractmetadatabase.h.

LinkList

typedef QList< QgsAbstractMetadataBase::Link > QgsAbstractMetadataBase::LinkList

A list of links.

Since

QGIS 3.2

Definition at line 263 of file qgsabstractmetadatabase.h.

QgsLayoutTableColumns

typedef QVector<QgsLayoutTableColumn> QgsLayoutTableColumns

List of column definitions for a QgsLayoutTable.

Since

QGIS 3.0

Definition at line 58 of file qgslayouttable.h.

QgsLayoutTableContents

typedef QVector< QgsLayoutTableRow > QgsLayoutTableContents

List of QgsLayoutTableRows, representing rows and column cell contents for a QgsLayoutTable.

Since

QGIS 3.0

Definition at line 47 of file qgslayouttable.h.

QgsLayoutTableRow

typedef QVector< QVariant > QgsLayoutTableRow

List of QVariants, representing a the contents of a single row in a QgsLayoutTable.

Since

QGIS 3.0

Definition at line 38 of file qgslayouttable.h.

QgsLayoutTableSortColumns

typedef QVector<QgsLayoutTableColumn> QgsLayoutTableSortColumns

List of column definitions for sorting a QgsLayoutTable.

Since

QGIS 3.14

Definition at line 65 of file qgslayouttable.h.

QgsNamedColorList

typedef QList< QPair< QColor, QString > > QgsNamedColorList

List of colors paired with a friendly display name identifying the color.

Since

QGIS 2.5

Definition at line 34 of file qgscolorscheme.h.

QgsSmartConditionMap

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 doesn't have the tag matching 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

Note

This is a Multimap, which means it will contain multiple values for the same key.
