Member Enumeration Documentation

RenderPhase

enum KOSMIndoorMap::SceneGraphItemPayload::RenderPhase : uint8_t

See MapCSS spec: "Within a layer, first all fills are rendered, then all casings, then all strokes, then all icons and labels." .

Member Function Documentation

boundingRect()

virtual QRectF KOSMIndoorMap::SceneGraphItemPayload::boundingRect ( const View * view ) const

nodiscardpure virtual

Bounding box of this item in scene coordinates.

Performance trumps precision here, so estimating this slightly larger rather than computing it expensively makes sense.

Implemented in KOSMIndoorMap::LabelItem, KOSMIndoorMap::MultiPolygonItem, KOSMIndoorMap::PolygonItem, and KOSMIndoorMap::PolylineItem.

inHUDSpace()

bool SceneGraphItemPayload::inHUDSpace ( ) const

nodiscard

Is this item drawn in HUD coordinates (as oposed to scene coordinates)?

Definition at line 22 of file scenegraphitem.cpp.

inSceneSpace()

bool SceneGraphItemPayload::inSceneSpace ( ) const

nodiscard

Is this item drawn in scene coordinates (as oposed to HUD coordinates)?

Definition at line 17 of file scenegraphitem.cpp.

renderPhases()

virtual uint8_t KOSMIndoorMap::SceneGraphItemPayload::renderPhases ( ) const

nodiscardpure virtual

Returns in which phase this item needs to be rendered (can be multiple).

Implemented in KOSMIndoorMap::LabelItem, KOSMIndoorMap::PolygonBaseItem, and KOSMIndoorMap::PolylineItem.
