Constructor & Destructor Documentation

TreeNode()

TreeNode	(	QGraphicsScene *	scene,
		QSize	nodeSize = TreeNode::DefaultNodeSize )

Constructs a tree node as part of a Qt visualizable tree.

Parameters

scene	the graphics scene used for rendering
nodeSite	size of the nodes boundingbox

Member Function Documentation

addChild()

void addChild

(

TreeNodePtr

child

)

Adds a child to the node in the tree structure.

Parameters

child

the child to add

drawEdge()

void drawEdge ( QLineF line )

protectedvirtual

Draws an edge to this node.

Overwrite this in order provide your own visualization.

Parameters

line	line from parent to this node

Reimplemented in TermNode.

drawNode()

void drawNode ( QRectF boundingBox )

protectedvirtual

Draws the node.

Overwrite this in order provide your own visualization.

Parameters

boundingBox

of the node to be drawn

Reimplemented in TermNode.

getBoundingBox()

QRectF getBoundingBox ( )

inline

Retrieve boundingbox of the node.

Only valid after update has been called.

Returns

boundingbox of the node in the graphicsscene

getChildren()

std::vector< TreeNodePtr > getChildren

(

)

const

getSize()

QSize getSize ( )

inline

Retrieve size of the node.

Returns

node size

getSubTreeSize()

QSize getSubTreeSize ( )

inline

Retrieve size of the complete subtree where the current node is root.

Only valid after update has been callse;

Returns

size of the subtree represented by this node

setSize()

void setSize ( QSize nodeSize )

inlineprotected

Sets size of node.

Layout has to be updated afterwards.

Parameters

nodeSize

size of the node

update()

void update

(

QPointF

positionLeftTop = QPointF(0, 0)

)

Updates the layout of the tree.

Only applicable for the root node. Is ignored for all other nodes.

Parameters

positionLeftTop

left top position in the graphicsscene, where the tree is drawn.
