Constructor & Destructor Documentation

LabelNode() [1/2]

LabelNode::LabelNode	(	SkyObject *	skyObject,
		LabelsItem::label_t	type )

Constructor.

Use name of skyObject as a text

Parameters

skyObject	- target object, for which this label is created.
type	- type of label (corresponds to type of SkyObject)

Definition at line 15 of file labelnode.cpp.

LabelNode() [2/2]

LabelNode::LabelNode	(	QString	name,
		LabelsItem::label_t	type )

Constructor.

Use string parameter name as a text

Parameters

name	- text of label
type	- type of label (corresponds to type of SkyObject)

Definition at line 22 of file labelnode.cpp.

~LabelNode()

LabelNode::~LabelNode ( )

virtual

Destructor.

Definition at line 28 of file labelnode.cpp.

Member Function Documentation

changePos()

void LabelNode::changePos ( QPointF pos )

overridevirtual

Changes position of the label.

Parameters

pos	- new position

Reimplemented from SkyNode.

Definition at line 114 of file labelnode.cpp.

createTexture()

void LabelNode::createTexture

(

QColor

color = QColor()

)

Create texture from label's name.

Parameters

color

- color of the label

Definition at line 74 of file labelnode.cpp.

initialize()

void LabelNode::initialize

(

)

Convenience function to not to repeat the same code in 2 constructors.

Set parameters of label based on its type

Definition at line 35 of file labelnode.cpp.

labelType()

LabelsItem::label_t LabelNode::labelType ( )

inline

Definition at line 62 of file labelnode.h.

name()

QString LabelNode::name ( )

inline

Definition at line 60 of file labelnode.h.

setLabelPos()

void LabelNode::setLabelPos

(

QPointF

pos

)

set the position of label with the given offset from SkyObject's position and makes the label visible if it was hidden

Warning

Keep mind that to update labels position, you should first set it with setLabelPos() and then call update()

Parameters

pos	position of label

Definition at line 123 of file labelnode.cpp.

update()

void LabelNode::update ( )

overridevirtual

Update position of label according to labelPos and recreate texture if label's size depends on zoom level.

Reimplemented from SkyNode.

Definition at line 135 of file labelnode.cpp.

zoomFont()

bool LabelNode::zoomFont ( )

inline

Returns

true if the size of text depends on zoom

Definition at line 73 of file labelnode.h.
