Constructor & Destructor Documentation

◆ QgsMarkerLineSymbolLayer()

QgsMarkerLineSymbolLayer::QgsMarkerLineSymbolLayer ( bool  rotateMarker = DEFAULT_MARKERLINE_ROTATE,
double  interval = 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.

◆ color()

QColor QgsMarkerLineSymbolLayer::color ( ) const
overridevirtual

The fill color.

Reimplemented from QgsSymbolLayer.

Definition at line 1740 of file qgslinesymbollayer.cpp.

◆ create()

QgsSymbolLayer * QgsMarkerLineSymbolLayer::create ( const QgsStringMap properties = QgsStringMap())
static

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

Definition at line 1714 of file qgslinesymbollayer.cpp.

◆ createFromSld()

QgsSymbolLayer * QgsMarkerLineSymbolLayer::createFromSld ( QDomElement &  element)
static

Creates a new QgsMarkerLineSymbolLayer from an SLD XML DOM element.

Definition at line 1848 of file qgslinesymbollayer.cpp.

◆ estimateMaxBleed()

double QgsMarkerLineSymbolLayer::estimateMaxBleed ( const QgsRenderContext context) const
overridevirtual

Returns the estimated maximum distance which the layer style will bleed outside the drawn shape when drawn in the specified /a context.

For example, polygons drawn with an stroke will draw half the width of the stroke outside of the polygon. This amount is estimated, since it may be affected by data defined symbology rules.

Reimplemented from QgsSymbolLayer.

Definition at line 2001 of file qgslinesymbollayer.cpp.

◆ hasDataDefinedProperties()

bool QgsMarkerLineSymbolLayer::hasDataDefinedProperties ( ) const
overridevirtual

Returns true if the symbol layer (or any of its sub-symbols) contains data defined properties.

Since
QGIS 3.4.5

Reimplemented from QgsSymbolLayer.

Definition at line 1992 of file qgslinesymbollayer.cpp.

◆ layerType()

QString QgsMarkerLineSymbolLayer::layerType ( ) const
overridevirtual

Returns a string that represents this layer type.

Used for serialization. Should match with the string used to register this symbol layer in the registry.

Implements QgsSymbolLayer.

Definition at line 1729 of file qgslinesymbollayer.cpp.

◆ renderSymbol()

void QgsMarkerLineSymbolLayer::renderSymbol ( const QPointF &  point,
const QgsFeature feature,
QgsRenderContext context,
int  layer = -1,
bool  selected = false 
)
overrideprotectedvirtual

Renders the templated symbol at the specified point, using the given render context.

The feature argument is used to pass the feature currently being rendered (when available).

If only a single symbol layer from the symbol should be rendered, it should be specified in the layer argument. A layer of -1 indicates that all symbol layers should be rendered.

If selected is true then the symbol will be drawn using the "selected feature" style and colors instead of the symbol's normal style.

Implements QgsTemplatedLineSymbolLayerBase.

Definition at line 1959 of file qgslinesymbollayer.cpp.

◆ rotateMarker()

Q_DECL_DEPRECATED bool QgsMarkerLineSymbolLayer::rotateMarker ( ) const
inline

Shall the marker be rotated.

Returns
true if the marker should be rotated.
Deprecated:
Use rotateSymbols() instead.

Definition at line 620 of file qgslinesymbollayer.h.

◆ setColor()

void QgsMarkerLineSymbolLayer::setColor ( const QColor &  color)
overridevirtual

The fill color.

Reimplemented from QgsSymbolLayer.

Definition at line 1734 of file qgslinesymbollayer.cpp.

◆ setDataDefinedProperty()

void QgsMarkerLineSymbolLayer::setDataDefinedProperty ( QgsSymbolLayer::Property  key,
const QgsProperty property 
)
overridevirtual

Sets a data defined property for the layer.

Any existing property with the same key will be overwritten.

dataDefinedProperties()
Property
Since
QGIS 3.0

Reimplemented from QgsSymbolLayer.

Definition at line 1935 of file qgslinesymbollayer.cpp.

◆ setOutputUnit()

void QgsMarkerLineSymbolLayer::setOutputUnit ( QgsUnitTypes::RenderUnit  unit)
overridevirtual

Sets the units to use for sizes and widths within the symbol layer.

Individual symbol layer subclasses will interpret this in different ways, e.g., a marker symbol layer may use it to specify the units for the marker size, while a line symbol layer may use it to specify the units for the line width.

Parameters
unitoutput units
See also
outputUnit()

Reimplemented from QgsSymbolLayer.

Definition at line 1974 of file qgslinesymbollayer.cpp.

◆ setRotateMarker()

Q_DECL_DEPRECATED void QgsMarkerLineSymbolLayer::setRotateMarker ( bool  rotate)
inline

Shall the marker be rotated.

Deprecated:
Use setRotateSymbols() instead.

Definition at line 626 of file qgslinesymbollayer.h.

◆ setSubSymbol()

bool QgsMarkerLineSymbolLayer::setSubSymbol ( QgsSymbol symbol)
overridevirtual

Sets layer's subsymbol. takes ownership of the passed symbol.

Reimplemented from QgsSymbolLayer.

Definition at line 1689 of file qgslinesymbollayer.cpp.

◆ setSymbolAngle()

void QgsMarkerLineSymbolLayer::setSymbolAngle ( double  angle)
overrideprotectedvirtual

Sets the symbol's angle, in degrees clockwise.

Implements QgsTemplatedLineSymbolLayerBase.

Definition at line 1954 of file qgslinesymbollayer.cpp.

◆ setSymbolLineAngle()

void QgsMarkerLineSymbolLayer::setSymbolLineAngle ( double  angle)
overrideprotectedvirtual

Sets the line angle modification for the symbol's angle.

This angle is added to the symbol's rotation and data defined rotation before rendering the symbol, and is used for orienting symbols to match the line's angle.

Parameters
angleAngle in degrees, valid values are between 0 and 360

Implements QgsTemplatedLineSymbolLayerBase.

Definition at line 1944 of file qgslinesymbollayer.cpp.

◆ setWidth()

void QgsMarkerLineSymbolLayer::setWidth ( double  width)
overridevirtual

Sets the width of the line symbol layer.

Calling this method updates the width of the line symbol layer, without changing the existing width units. It has different effects depending on the line symbol layer subclass, e.g. for a simple line layer it changes the stroke width of the line, for a marker line layer it changes the size of the markers used to draw the line.

See also
width()
Warning
Since the width units vary, this method is useful for changing the relative width of a line symbol layer only.

Reimplemented from QgsLineSymbolLayer.

Definition at line 1930 of file qgslinesymbollayer.cpp.

◆ startRender()

void QgsMarkerLineSymbolLayer::startRender ( QgsSymbolRenderContext context)
overridevirtual

overridevirtual

Returns the set of attributes referenced by the layer.

This includes attributes required by any data defined properties associated with the layer.

Reimplemented from QgsSymbolLayer.

Definition at line 1984 of file qgslinesymbollayer.cpp.

◆ width() [1/2]

double QgsMarkerLineSymbolLayer::width ( ) const
overridevirtual

Returns the estimated width for the line symbol layer.

Warning
This returned value is inaccurate if the symbol layer has sub-symbols with different width units. Use the overload accepting a QgsRenderContext argument instead for accurate sizes in this case.
