Member Enumeration Documentation

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

virtual QRectF KOSMIndoorMap::SceneGraphItemPayload::boundingRect ( ) const

pure 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.

bool SceneGraphItemPayload::inHUDSpace

(

)

const

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

Definition at line 20 of file scenegraphitem.cpp.

bool SceneGraphItemPayload::inSceneSpace

(

)

const

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

Definition at line 15 of file scenegraphitem.cpp.

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

pure virtual

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

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