Detailed Description

A SkyNode derived class used for displaying DeepSkyObjects.

Keep in mind that DSO symbol is handled by DSOSymbolNode that has different parent from this node but DeepSkyNode calls update routines of DSOSymbolNode.

Constructor & Destructor Documentation

◆ DeepSkyNode()

DeepSkyNode::DeepSkyNode ( DeepSkyObject *  skyObject,
DSOSymbolNode symbol,
LabelsItem::label_t  labelType,
short  trixel = -1 
)

Constructor.

Parameters
skyObject- DSOs that is represented by this node
symbol- DSOSymbolNode of this DSO
labelType- type of label
trixel- trixelID, with which this node is indexed

Definition at line 22 of file deepskynode.cpp.

◆ ~DeepSkyNode()

DeepSkyNode::~DeepSkyNode ( )
virtual

Destructor.

Call delete routines of label

Definition at line 28 of file deepskynode.cpp.

Member Function Documentation

◆ changePos()

void DeepSkyNode::changePos ( QPointF  pos)
overridevirtual

changePos changes the position of this node and rotate it according to m_angle

Parameters
posnew position

Reimplemented from SkyNode.

Definition at line 34 of file deepskynode.cpp.

◆ hide()

void DeepSkyNode::hide ( )
overridevirtual

hides all child nodes (sets opacity of m_opacity to 0)

Reimplemented from SkyNode.

Definition at line 142 of file deepskynode.cpp.

◆ setColor()

void DeepSkyNode::setColor ( QColor  color,
TrixelNode symbolTrixel 
)

sets color of DSO symbol and label To not increase the code for symbols we just recreate the symbol painted with desired color

Parameters
colorthe color to be set
symbolTrixelthe TrixelNode to which symbol node should be appended

Definition at line 46 of file deepskynode.cpp.

◆ update()

void DeepSkyNode::update ( bool  drawImage,
bool  drawLabel,
QPointF  pos = QPointF(-1, -1) 
)

Update position and visibility of this node.

Parameters
drawImage- true if image (if exists) should be drawn
drawLabel- true if label should be drawn
pos- new position of the object. If default parameter is passed, the visibility and position of node is calculated. There is one case when we pass this parameter - in DeepSkyItem::updateDeepSkyNode() when we check whether DeepSkyObject is visible or no and instantiate it accordingly. There is no need to calculate the position again and we pass it as a parameter.
