Constructor & Destructor Documentation

◆ QgsSingleBoxScaleBarRenderer()

QgsSingleBoxScaleBarRenderer::QgsSingleBoxScaleBarRenderer ( )
default

Constructor for QgsSingleBoxScaleBarRenderer.

Member Function Documentation

◆ clone()

QgsSingleBoxScaleBarRenderer * QgsSingleBoxScaleBarRenderer::clone ( ) const
overridevirtual

Returns a clone of the renderer.

The caller takes ownership of the returned value.

Implements QgsScaleBarRenderer.

Definition at line 56 of file qgssingleboxscalebarrenderer.cpp.

◆ draw()

void QgsSingleBoxScaleBarRenderer::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 61 of file qgssingleboxscalebarrenderer.cpp.

◆ flags()

QgsScaleBarRenderer::Flags QgsSingleBoxScaleBarRenderer::flags ( ) const
overridevirtual

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

Since
QGIS 3.14

Reimplemented from QgsScaleBarRenderer.

Definition at line 42 of file qgssingleboxscalebarrenderer.cpp.

◆ id()

QString QgsSingleBoxScaleBarRenderer::id ( ) const
overridevirtual

Returns the unique ID for this renderer.

Since
QGIS 3.14

Implements QgsScaleBarRenderer.

Definition at line 27 of file qgssingleboxscalebarrenderer.cpp.

◆ sortKey()

int QgsSingleBoxScaleBarRenderer::sortKey ( ) const
overridevirtual

Returns a sorting key value, where renderers with a lower sort key will be shown earlier in lists.

Generally, subclasses should return QgsScaleBarRenderer::sortKey() as their sorting key.

Reimplemented from QgsScaleBarRenderer.

Definition at line 37 of file qgssingleboxscalebarrenderer.cpp.

◆ visibleName()

QString QgsSingleBoxScaleBarRenderer::visibleName ( ) const
overridevirtual

Returns the user friendly, translated name for the renderer.

Since
QGIS 3.14

Implements QgsScaleBarRenderer.

Definition at line 32 of file qgssingleboxscalebarrenderer.cpp.
