Constructor & Destructor Documentation

◆ LabelNode() [1/2]

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


Use name of skyObject as a text

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 )


Use string parameter name as a text

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

Definition at line 22 of file labelnode.cpp.

◆ ~LabelNode()

LabelNode::~LabelNode ( )


Definition at line 28 of file labelnode.cpp.

Member Function Documentation

◆ changePos()

void LabelNode::changePos ( QPointF pos)

Changes position of the label.

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.

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 ( )

Definition at line 62 of file labelnode.h.

◆ name()

QString LabelNode::name ( )

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

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

Definition at line 123 of file labelnode.cpp.

◆ update()

void LabelNode::update ( )

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 ( )
true if the size of text depends on zoom

Definition at line 73 of file labelnode.h.
