Documentation

Switch is a Group node which allows switching between children. Typical uses would be for objects which might need to be rendered differently at different times, for instance a switch could be used to represent the different states of a traffic light.

Switch()

Switch(const Switch&, const CopyOp& copyop=CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

META_Node(osg, Switch)

virtual void traverse(NodeVisitor& nv)

void setNewChildDefaultValue(bool value)

bool getNewChildDefaultValue() const

virtual bool addChild( Node* child )

virtual bool addChild( Node* child, bool value )

virtual bool insertChild( unsigned int index, Node* child )

virtual bool insertChild( unsigned int index, Node* child, bool value )

virtual bool removeChild( Node* child )

void setValue(unsigned int pos, bool value)

bool getValue(unsigned int pos) const

void setChildValue(const Node* child, bool value)

bool getChildValue(const Node* child) const

bool setAllChildrenOff()

Set all the children off (false), and set the new default child value to off (false)

bool setAllChildrenOn()

Set all the children on (true), and set the new default child value to on (true)

bool setSingleChildOn(unsigned int pos)

Set a single child to be on, switch off all other children

enum Values

Special values for the Switch. Use these if you want to turn on/off all child nodes.

ALL_CHILDREN_ON

All children turned on.

ALL_CHILDREN_OFF

All children off.

MULTIPLE_CHILDREN_ON

Multiple children turned on

void setValue(int value)

Selects the active child Node or enables a special SwitchType mode.

Parameters:

value - the number of the active child (first child == number 0) or SwitchType. Invalid values will be ignored.

int getValue() const

typedef std::vector<bool> ValueList

const ValueList& getValueList() const

virtual ~Switch()

bool _newChildDefaultValue

ValueList _values

This class has no child classes.
