public class MarkCursor
extends ZoomCursor

A cursor-like application that supplies a cross-hair above the entire drawable area of a JShapeCanvas. If persitant marking is enabled with the CrossCursor.KEY_PERSISTENT key, then clicking on the canvas adds a cross-hair on the location clicked to the shape canvas.

Constructs a new cross cursor from properties.

Method Summary

void	enableCanvas(JNormalizedCanvas root) Assigns the JShapeCanvas to the cursor.
Action	getClearAction() Returns the action that saves the underlying component.
void	init() Initializes the zoom cursor.
void	mouseClicked(MouseEvent me) If persistent storage is enabled via the CrossCursor.KEY_PERSISTENT key, clicking of the mouse adds a cross-shape to the underlying canvas or removes it if it happens close to a priorly added cross-shape.
void	setComposedProperties(PropertySupplying info) Compose with a PropertySupplying as we need subclassing Cursor.

Constructor Detail

MarkCursor

public MarkCursor(PropertySupplying prop)

Constructs a new cross cursor from properties. Needs to register the JShapeCanvas manually.

Method Detail

init

public void init()

Initializes the zoom cursor. Here, the pop-up menu and the undo-zoom list is generated.

Specified by:

init in interface Initializable

Overrides:

init in class ZoomCursor

setComposedProperties

public void setComposedProperties(PropertySupplying info)

Compose with a PropertySupplying as we need subclassing Cursor.

Specified by:

setComposedProperties in interface PropertyAware

Overrides:

setComposedProperties in class ZoomCursor

getClearAction

public Action getClearAction()

Returns the action that saves the underlying component.

mouseClicked

public void mouseClicked(MouseEvent me)

If persistent storage is enabled via the CrossCursor.KEY_PERSISTENT key, clicking of the mouse adds a cross-shape to the underlying canvas or removes it if it happens close to a priorly added cross-shape.

Specified by:

mouseClicked in interface MouseListener

Overrides:

mouseClicked in class ZoomCursor

enableCanvas

public void enableCanvas(JNormalizedCanvas root)

Assigns the JShapeCanvas to the cursor. This method must always be called prior to activation of the cursor, i.e. adding it as a mouse listener.

Overrides:

enableCanvas in class CanvasCursor
