◆ DirectionSymbols

enum QgsPalLayerSettings::DirectionSymbols

Enumerator
SymbolLeftRight	place direction symbols on left/right of label
SymbolAbove	place direction symbols on above label
SymbolBelow	place direction symbols on below label

Definition at line 161 of file qgspallabeling.h.

◆ LinePlacementFlags

enum QgsPalLayerSettings::LinePlacementFlags

Line placement flags, which control how candidates are generated for a linear feature.

Enumerator
OnLine	Labels can be placed directly over a line feature.
AboveLine	Labels can be placed above a line feature. Unless MapOrientation is also specified this mode respects the direction of the line feature, so a line from right to left labels will have labels placed placed below the line feature.
BelowLine	Labels can be placed below a line feature. Unless MapOrientation is also specified this mode respects the direction of the line feature, so a line from right to left labels will have labels placed placed above the line feature.
MapOrientation	Signifies that the AboveLine and BelowLine flags should respect the map's orientation rather than the feature's orientation. Eg, AboveLine will always result in label's being placed above a line, regardless of the line's direction.

Definition at line 127 of file qgspallabeling.h.

◆ MultiLineAlign

enum QgsPalLayerSettings::MultiLineAlign

Enumerator
MultiLeft
MultiCenter
MultiRight
MultiFollowPlacement	Alignment follows placement of label, eg labels to the left of a feature will be drawn with right alignment

Definition at line 168 of file qgspallabeling.h.

◆ ObstacleType

enum QgsPalLayerSettings::ObstacleType

Valid obstacle types, which affect how features within the layer will act as obstacles for labels.

Enumerator
PolygonInterior	avoid placing labels over interior of polygon (prefer placing labels totally outside or just slightly inside polygon)
PolygonBoundary	avoid placing labels over boundary of polygon (prefer placing outside or completely inside polygon)
PolygonWhole	avoid placing labels over ANY part of polygon. Where PolygonInterior will prefer to place labels with the smallest area of intersection between the label and the polygon, PolygonWhole will penalise any label which intersects with the polygon by an equal amount, so that placing labels over any part of the polygon is avoided.

Definition at line 181 of file qgspallabeling.h.

◆ OffsetType

enum QgsPalLayerSettings::OffsetType

Behaviour modifier for label offset and distance, only applies in some label placement modes.

Enumerator
FromPoint	Offset distance applies from point geometry.

Definition at line 117 of file qgspallabeling.h.

◆ Placement

enum QgsPalLayerSettings::Placement

Placement modes which determine how label candidates are generated for a feature.

Enumerator
AroundPoint	Arranges candidates in a circle around a point (or centroid of a polygon). Applies to point or polygon layers only.
OverPoint
Line	Arranges candidates over a point (or centroid of a polygon), or at a preset offset from the point. Applies to point or polygon layers only. Arranges candidates parallel to a generalised line representing the feature or parallel to a polygon's perimeter. Applies to line or polygon layers only.
Curved
Horizontal	Arranges candidates following the curvature of a line feature. Applies to line layers only. Arranges horizontal candidates scattered throughout a polygon feature. Applies to polygon layers only.
Free	Arranges candidates scattered throughout a polygon feature. Candidates are rotated to respect the polygon's orientation. Applies to polygon layers only.
OrderedPositionsAroundPoint	Candidates are placed in predefined positions around a point. Peference is given to positions with greatest cartographic appeal, eg top right, bottom right, etc. Applies to point layers only.
PerimeterCurved

◆ drawLabels

bool QgsPalLayerSettings::drawLabels

Whether to draw labels for this layer.

For some layers it may be desirable to register their features as obstacles for other labels without requiring labels to be drawn for the layer itself. In this case drawLabels can be set to false and obstacle set to true, which will result in the layer acting as an obstacle but having no labels of its own.
