Detailed Description

Allows for creation of custom markers on objects or coordinates.

Because this class is intended for use in scripting (although other uses are also fine), all marker types and so on are specified by QString descriptions. The markers are painted very late, i.e. also sky object markers will be written over the landscape.

Note: The "Markers" which can be set interactively by mouse click are actually CustomObjects and managed by the CustomObjectMgr.

Member Function Documentation

◆ deleteAllMarkers

int MarkerMgr::deleteAllMarkers ( void )

slot

Delete all markers.

Returns: the number of markers deleted

◆ deleteMarker

void MarkerMgr::deleteMarker ( int id )

slot

Delete a marker identified by positive ID.

Returns: true if the id existed and was deleted, else false

◆ markerEquatorial

int MarkerMgr::markerEquatorial	(	const QString &	RA,
		const QString &	Dec,
		bool	j2000epoch = `true`,
		bool	visible = `true`,
		const QString &	mtype = `"cross"`,
		const QString &	color = `"#ffff66"`,
		const float	size = `6.f`,
		bool	autoDelete = `false`,
		int	autoDeleteTimeoutMs = `0`,
		bool	withAberration = `true`
	)

slot

Create a marker with mean equatorial coordinates.

Parameters

RA	right ascension (e.g. 5h10m31s)
Dec	declination (e.g. 25d30m30s)
j2000epoch	if true, the coordinates are equatorial for epoch J2000.0. If false, they represent equatorial coordinates for equinox of current date and will be converted to J2000 coordinates at time of creation.

Note: It is not possible to create a marker in equatorial coordinate of date which changes with precession.

Parameters

visible	if true, the marker starts displayed, else it starts hidden
mtype	the type of marker. Keys: cross: simple cross circle: simple circle ellipse: simple horizontal ellipse square: simple square dotted-circle: simple circle drawn by dots circled-cross (or circled-plus): simple circle with cross inside the circle dashed-square: simple square, drawing by dashed line squared-dotted-circle (or squared-dcircle): simple circle, drawing by dotted line crossed-circle: the cross under circle target: the target shape gear: the gear shape disk: the disk shape
color	HTML-like color spec, e.g. "#ffff00" for yellow
size	the size of marker.
autoDelete	the marker will be automatically deleted after it is displayed once
autoDeleteTimeoutMs	if not zero, the marker will be automatically deleted after autoDeleteTimeoutMs ms
withAberration	The coordinates will be subject to aberration. If false, they represent strict frame coordinates.

Returns: a unique ID which can be used to refer to the marker. returns -1 if the marker could not be created (e.g. object not found)

◆ markerHorizon

int MarkerMgr::markerHorizon	(	const QString &	az,
		const QString &	alt,
		bool	visible = `true`,
		const QString &	mtype = `"cross"`,
		const QString &	color = `"#ffff66"`,
		const float	size = `6.f`,
		bool	autoDelete = `false`,
		int	autoDeleteTimeoutMs = `0`
	)

slot

Create a marker with horizontal coordinates.

Parameters

az	azimuth (e.g. 125d30m30s)
alt	altitude (e.g. 25d30m30s)
visible	if true, the marker starts displayed, else it starts hidden
mtype	the type of marker. Keys: cross: simple cross circle: simple circle ellipse: simple horizontal ellipse square: simple square dotted-circle: simple circle drawn by dots circled-cross (or circled-plus): simple circle with cross inside the circle dashed-square: simple square, drawing by dashed line squared-dotted-circle (or squared-dcircle): simple circle, drawing by dotted line crossed-circle: the cross under circle target: the target shape gear: the gear shape disk: the disk shape
color	HTML-like color spec, e.g. "#ffff00" for yellow
size	the size of marker.
autoDelete	the marker will be automatically deleted after it is displayed once
autoDeleteTimeoutMs	if not zero, the marker will be automatically deleted after autoDeleteTimeoutMs ms

Returns: a unique ID which can be used to refer to the marker. returns -1 if the marker could not be created (e.g. object not found)

◆ markerObject

int MarkerMgr::markerObject	(	const QString &	objectName,
		bool	visible = `true`,
		const QString &	mtype = `"cross"`,
		const QString &	color = `"#ffff66"`,
		const float	size = `6.f`,
		bool	autoDelete = `false`,
		int	autoDeleteTimeoutMs = `0`
	)

slot

Create a marker which is attached to a StelObject.

Parameters

objectName	the English name of the object to attach to
visible	if true, the marker starts displayed, else it starts hidden
mtype	the type of marker. Keys: cross: simple cross circle: simple circle ellipse: simple horizontal ellipse square: simple square dotted-circle: simple circle drawn by dots circled-cross (or circled-plus): simple circle with cross inside the circle dashed-square: simple square, drawing by dashed line squared-dotted-circle (or squared-dcircle): simple circle, drawing by dotted line crossed-circle: the cross under circle target: the target shape gear: the gear shape disk: the disk shape
color	HTML-like color spec, e.g. "#ffff00" for yellow
size	the size of marker.
autoDelete	the marker will be automatically deleted after it is displayed once
autoDeleteTimeoutMs	if not zero, the marker will be automatically deleted after autoDeleteTimeoutMs ms

Returns: a unique ID which can be used to refer to the marker. returns -1 if the marker could not be created (e.g. object not found)

Note: The marker will be placed on the object's J2000 coordinates at time of marker creation and will undergo aberration correction.
