Class Hierarchy

Base classes

QgsTemplatedLineSymbolLayerBase	Base class for templated line symbols, e.g. line symbols which draw markers or hash lines at intervals along the line feature.
QgsLineSymbolLayer	Abstract base class for line symbol layers.
QgsSymbolLayer	Abstract base class for symbol layers.

Methods

rotateMarker	Shall the marker be rotated.
setRotateMarker	Shall the marker be rotated.

Static Methods

create	Creates a new QgsMarkerLineSymbolLayer, using the settings serialized in the properties map (corresponding to the output from QgsMarkerLineSymbolLayer.properties() ).
createFromSld	Creates a new QgsMarkerLineSymbolLayer from an SLD XML DOM element.

class qgis.core.QgsMarkerLineSymbolLayer

Bases: QgsTemplatedLineSymbolLayerBase

__init__(rotateMarker: bool = DEFAULT_MARKERLINE_ROTATE, interval: float = DEFAULT_MARKERLINE_INTERVAL)

Constructor for QgsMarkerLineSymbolLayer. Creates a marker line with a default marker symbol, placed at the specified interval (in millimeters).

The rotateMarker argument specifies whether individual marker symbols should be rotated to match the line segment alignment.

Parameters:

• rotateMarker (bool = DEFAULT_MARKERLINE_ROTATE)

• interval (float = DEFAULT_MARKERLINE_INTERVAL)

static create(properties: dict[str, Any] = {}) → QgsSymbolLayer | None

Creates a new QgsMarkerLineSymbolLayer, using the settings serialized in the properties map (corresponding to the output from QgsMarkerLineSymbolLayer.properties() ).

Parameters:

properties (dict[str, Any] = {})

Return type:

Optional[QgsSymbolLayer]

static createFromSld(element: QDomElement) → QgsSymbolLayer | None

Creates a new QgsMarkerLineSymbolLayer from an SLD XML DOM element.

Parameters:

element (QDomElement)

Return type:

Optional[QgsSymbolLayer]

rotateMarker(self) → bool

Shall the marker be rotated.

Return type:

bool

Returns:

True if the marker should be rotated.

Deprecated since version 3.40: Use rotateSymbols() instead.

setRotateMarker(self, rotate: bool)

Shall the marker be rotated.

Deprecated since version 3.40: Use setRotateSymbols() instead.

Parameters:

rotate (bool)
