Member Function Documentation

◆ addLayerRecord()

void QgsMapThemeCollection::MapThemeRecord::addLayerRecord ( const QgsMapThemeCollection::MapThemeLayerRecord & record )

Add a new record for a layer.

Definition at line 549 of file qgsmapthemecollection.cpp.

◆ checkedGroupNodes()

QSet< QString > QgsMapThemeCollection::MapThemeRecord::checkedGroupNodes ( ) const

inline

Returns a set of group identifiers for group nodes that should have checked state (other group nodes should be unchecked).

The returned value is valid only when hasCheckedStateInfo() returns true. Group identifiers are built using group names, a sub-group name is prepended by parent group's identifier and a forward slash, e.g. "level1/level2"

Since: QGIS 3.10.1

Definition at line 193 of file qgsmapthemecollection.h.

◆ expandedGroupNodes()

QSet< QString > QgsMapThemeCollection::MapThemeRecord::expandedGroupNodes ( ) const

inline

Returns a set of group identifiers for group nodes that should have expanded state (other group nodes should be collapsed).

The returned value is valid only when hasExpandedStateInfo() returns true. Group identifiers are built using group names, a sub-group name is prepended by parent group's identifier and a forward slash, e.g. "level1/level2"
