27 * This class is in charge of labels in SkyMapLite. Labels can be instantiated by calling addLabel with
28 * either SkyObject or plain QString as a name. There are two types of label nodes available - LabelNode
29 * that can't be rotated and GuideLabelNode that supports rotation (but it is not used anywhere yet).
31 * To prevent labels from overlapping this class uses SkyLabeler. We check LabelNode for overlapping by
34 * Each of SkyItems that uses labels has its own label type in enum label_t (copied from SkyLabeler but
36 * to hide all labels of some type you just need to set opacity of LabelTypeNode that corresponds to
39 * Order of drawing can be changed in LabelsItem's constructor. Order of labels update can be changed in
42 * This class is not derived from SkyItem as it doesn't have label type and SkyItem's header needs an
96 * can be hidden whenever Trixel is not displayed. Use for sky objects that are indexed by SkyMesh
LabelNode * addLabel(SkyObject *skyObject, label_t labelType)
Create LabelNode with given skyObject and append it to LabelTypeNode that corresponds to type.
