Method Details

getNode

public javafx.scene.Group getNode(DrawingView view)

Description copied from interface: Handle

Returns the node which is used to visualize the handle. The node is rendered by DrawingView in a pane which uses view coordinates. The node should use DrawingView.viewToDrawingProperty() to transform its coordinates.

A Handle can only reside in one DrawingView at any given time. The JavaFX node returned by this method is use to render the handle in the DrawingView. This is why, unlike Figure, we only need this method instead of a createNode and an updateNode method.

A HandleTracker will use the Node.accessibleTextProperty() and Node.accessibleHelpProperty() to provide a help text to the user.

Parameters:

view - the drawing view

Returns:

the node

updateNode

public void updateNode(DrawingView view)

Description copied from interface: Handle

Updates the node.

Parameters:

view - the drawing view
