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

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

pos	new position

Reimplemented from SkyNode.

Definition at line 34 of file deepskynode.cpp.

dsObject()

DeepSkyObject * DeepSkyNode::dsObject ( )

inline

Definition at line 75 of file deepskynode.h.

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

color	the color to be set
symbolTrixel	the TrixelNode to which symbol node should be appended

Definition at line 46 of file deepskynode.cpp.

symbol()

DSOSymbolNode * DeepSkyNode::symbol ( )

inline

Definition at line 76 of file deepskynode.h.

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.
