BoundsInParentOutlineHandle

public BoundsInParentOutlineHandle(Figure figure)

Method Details

contains

public boolean contains(DrawingView dv,
 double x,
 double y,
 double tolerance)

Description copied from interface: Handle

Whether the user picked the handle.

Parameters:

dv - the drawing view

x - the point

y - the point

tolerance - the tolerance (radius around the point)

Returns:

true if we picked the handle

getCursor

public @Nullable javafx.scene.Cursor getCursor()

Description copied from interface: Handle

The cursor that should be shown when the mouse hovers over a selectable handle. Non-selectable handles should return null.

Returns:

the cursor

getNode

public javafx.scene.Node 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

initNode

protected void initNode(javafx.scene.shape.Polygon r)

isSelectable

public boolean isSelectable()

Description copied from interface: Handle

Whether the handle is selectable.

Returns:

true if selectable

updateNode

public void updateNode(DrawingView view)

Description copied from interface: Handle

Updates the node.

Parameters:

view - the drawing view
