Virtual destructor.

Member Function Documentation

◆ addObserver()

void dart::common::Subject::addObserver ( Observer * _observer ) const

protectedinherited

Add an Observer to the list of Observers.

◆ addSubject()

void dart::common::Observer::addSubject ( const Subject * _subject )

protectedinherited

Add a Subject for this Observer.

◆ constrainToLine()

void dart::gui::osg::DragAndDrop::constrainToLine ( const Eigen::Vector3d & slope )

inherited

Constrain translation to only occur along the given slope, or constrain rotation to only occur about the given slope.

For rotation, this function is equivalent to constrainToPlane

◆ constrainToPlane()

void dart::gui::osg::DragAndDrop::constrainToPlane ( const Eigen::Vector3d & normal )

inherited

Constrain translation to only occur within the plane defined by the given normal, or constrain rotation to only occur about the given normal.

For rotation, this function is equivalent to constrainToLine

◆ getConstrainedDx()

Eigen::Vector3d dart::gui::osg::DragAndDrop::getConstrainedDx ( ) const

virtualinherited

Default method for getting the translation requested by the user.

◆ getConstrainedRotation()

Eigen::AngleAxisd dart::gui::osg::DragAndDrop::getConstrainedRotation ( ) const

virtualinherited

Default method for getting the rotation requested by the user.

◆ getEntity()

dart::dynamics::Entity * dart::gui::osg::DragAndDrop::getEntity ( ) const

inherited

Get the Entity that this DragAndDrop is associated with.

◆ getFrame()

InteractiveFrame * dart::gui::osg::InteractiveFrameDnD::getFrame ( ) const

Get the frame associated with this DnD.

◆ getRotationModKey()

osgGA::GUIEventAdapter::ModKeyMask dart::gui::osg::DragAndDrop::getRotationModKey ( ) const

inherited

Get the modkey that will be used to toggle rotation for this DnD.

◆ getRotationOption()

DragAndDrop::RotationOption dart::gui::osg::DragAndDrop::getRotationOption ( ) const

inherited

Get the current rotation option for this DnD.

◆ handleDestructionNotification()

void dart::gui::osg::DragAndDrop::handleDestructionNotification ( const dart::common::Subject * subscription )

overrideprotectedvirtualinherited

Perform cleanup when the subject is destroyed.

Reimplemented from dart::common::Observer.

Reimplemented in dart::gui::osg::SimpleFrameShapeDnD.

◆ isMoving()

bool dart::gui::osg::DragAndDrop::isMoving ( ) const

inherited

Returns the mAmMoving flag.

◆ isObstructable()

bool dart::gui::osg::DragAndDrop::isObstructable ( ) const

inherited

If this is true, then this object will only be drag and droppable if there are no other objects between its picked point and the camera.

Default is true.

◆ move()

void dart::gui::osg::InteractiveFrameDnD::move ( )

overridevirtual

Called to specify how the Entity should be moved.

Implements dart::gui::osg::DragAndDrop.

◆ receiveDestructionNotification()

void dart::common::Observer::receiveDestructionNotification ( const Subject * _subject )

protectedinherited

Called whenever a Subject is destroyed (or sends out a destruction notification).

Override handleDestructionNotification() in order to customize your class's response to destruction notifications.

◆ release()

void dart::gui::osg::DragAndDrop::release ( )

virtualinherited

Called when the user lets go of the object that they are dragging and dropping.

This function does nothing by default, but you can override it.

Reimplemented in dart::gui::osg::BodyNodeDnD.

◆ removeAllSubjects()

void dart::common::Observer::removeAllSubjects ( )

protectedinherited

Remove all Subjects from this Observer.

◆ removeObserver()

void dart::common::Subject::removeObserver ( Observer * _observer ) const

protectedinherited

protectedinherited

Remove a Subject from this Observer.

◆ saveState()

void dart::gui::osg::InteractiveFrameDnD::saveState ( )

Implements dart::gui::osg::DragAndDrop.

◆ sendDestructionNotification()

void dart::common::Subject::sendDestructionNotification ( ) const

protectedinherited

Send a destruction notification to all Observers.

This will cause all Observers to behave as if this Subject has been permanently deleted, so it should only be called when that behavior is desired.

◆ setObstructable()

inherited

If true is passed in, this object will only be drag and droppable if there are no other objects between its picked point and the camera.

inherited

Set the option for triggering rotations instead of translations.

◆ unconstrain()

void dart::gui::osg::DragAndDrop::unconstrain ( )

inherited

Remove all constraints from the dragging and dropping.

◆ update()

void dart::gui::osg::InteractiveFrameDnD::update ( )

overridevirtual

Called when mouse events are being handled.

Reimplemented from dart::gui::osg::DragAndDrop.
