Member Function Documentation

◆ clone()

QgsTicksScaleBarRenderer * QgsTicksScaleBarRenderer::clone ( ) const

overridevirtual

Returns a clone of the renderer.

The caller takes ownership of the returned value.

Implements QgsScaleBarRenderer.

Definition at line 89 of file qgsticksscalebarrenderer.cpp.

◆ draw()

void QgsTicksScaleBarRenderer::draw	(	QgsRenderContext &	context,
		const QgsScaleBarSettings &	settings,
		const QgsScaleBarRenderer::ScaleBarContext &	scaleContext
	)		const

overridevirtual

Draws the scalebar using the specified settings and scaleContext to a destination render context.

Implements QgsScaleBarRenderer.

Definition at line 94 of file qgsticksscalebarrenderer.cpp.

◆ flags()

QgsScaleBarRenderer::Flags QgsTicksScaleBarRenderer::flags ( ) const

overridevirtual

Returns the scalebar rendering flags, which dictates the renderer's behavior.

Since: QGIS 3.14

Reimplemented from QgsScaleBarRenderer.

Definition at line 73 of file qgsticksscalebarrenderer.cpp.

◆ id()

QString QgsTicksScaleBarRenderer::id ( ) const

overridevirtual

Returns the unique ID for this renderer.

Since: QGIS 3.14

Implements QgsScaleBarRenderer.

Definition at line 30 of file qgsticksscalebarrenderer.cpp.

◆ setTickPosition()

void QgsTicksScaleBarRenderer::setTickPosition ( TickPosition position )

inline
