int labelObject(const QString &text, const QString &objectName, bool visible=true, float fontSize=14, const QString &fontColor="#999999", const QString &side="E", double labelDistance=-1.0, const QString &style="TextOnly")
Create a label which is attached to a StelObject.
bool deleteLabel(int id)
Delete a label by the ID which was returned from addLabel...
virtual void update(double deltaTime)
Update time-dependent parts of the module.
void setLabelText(int id, const QString &newText)
set text of label identified by id to be newText
void setLabelShow(int id, bool show)
set a label identified by id to be shown or not
Main class for Stellarium core processing.
Definition: StelCore.hpp:48
virtual double getCallOrder(StelModuleActionName actionName) const
Defines the order in which the various modules are drawn.
virtual void draw(StelCore *core)
Draw user labels.
Define the StelObjectP type.
Provides functions for performing openGL drawing operations.
Definition: StelPainter.hpp:40
bool getLabelShow(int id)
find out if a label identified by id is presently shown
int labelHorizon(const QString &text, float az, float alt, bool visible=true, float fontSize=14, const QString &fontColor="#999999")
Create a label in azimuthal coordinate system.
int deleteAllLabels(void)
Delete all labels.
StelModuleActionName
Define the possible action for which an order is defined.
Definition: StelModule.hpp:117
LabelMgr()
Construct a LabelMgr object.
int labelScreen(const QString &text, int x, int y, bool visible=true, float fontSize=14, const QString &fontColor="#999999")
Create a label at fixed screen coordinates.
virtual void init()
Initialize the LabelMgr object.
Allows for creation of custom labels on objects or coordinates.
Definition: LabelMgr.hpp:46
This is the common base class for all the main components of stellarium.
