◆ isValid()

bool QgsScaleBarRenderer::ScaleBarContext::isValid ( ) const

Returns true if the context has valid settings.

Since: QGIS 3.40

Member Data Documentation

◆ flags

Flags QgsScaleBarRenderer::ScaleBarContext::flags

Scalebar renderer flags.

Definition at line 89 of file qgsscalebarrenderer.h.

◆ scale

double QgsScaleBarRenderer::ScaleBarContext::scale { 1.0 }

Scale denominator.

Definition at line 86 of file qgsscalebarrenderer.h.

◆ segmentWidth

double QgsScaleBarRenderer::ScaleBarContext::segmentWidth { 0.0 }

The width, in millimeters, of each individual segment drawn.

Note: The number of map units per segment needs to be set via QgsScaleBarSettings::setUnitsPerSegment.

Definition at line 76 of file qgsscalebarrenderer.h.

◆ size

QSizeF QgsScaleBarRenderer::ScaleBarContext::size

Destination size for scalebar.

This is used for scalebars which alter their appearance or alignment based on the desired scalebar size (e.g. correctly aligning text in a numeric scale bar).
