protected void	handleCopy(TimedStroke stk) Copy whatever is in the center of the stroke.
protected void	handleCut(TimedStroke stk) Cut whatever intersects the stroke.
protected void	handleDelete(TimedStroke stk) Delete whatever is in the center of the stroke (except ourself of course).
protected void	handlePaste(TimedStroke stk) Paste to the bottom-center of the stroke.
protected void	handleRedo() Handle a redo.

Constructor Detail

StandardGestureInterpreter

public StandardGestureInterpreter()

Method Detail

setShallow

public void setShallow()

Set the GraphicalObject retrieval to be shallow (in terms of the data structure, ie one level). This affects how cut, copy, paste, and delete work.

setDeep

public void setDeep()

Set the GraphicalObject retrieval to be deep (in terms of the data structure, ie one level). This affects how cut, copy, paste, and delete work.

handleSingleStroke

public void handleSingleStroke(SingleStrokeEvent evt)

Description copied from class: InterpreterImpl

By default, does nothing.

Overrides:

handleSingleStroke in class InterpreterImpl

Following copied from interface: edu.berkeley.guir.lib.satin.event.StrokeListener

See Also:

StrokeListener.handleNewStroke(NewStrokeEvent).

handleUndo

protected void handleUndo()

Handle an undo. Override this method if you want.

handleRedo

protected void handleRedo()

Handle a redo. Override this method if you want.

handleCut

protected void handleCut(TimedStroke stk)

Cut whatever intersects the stroke. Override this method if you want.

handleCopy

protected void handleCopy(TimedStroke stk)

Copy whatever is in the center of the stroke. Override this method if you want.

handlePaste

protected void handlePaste(TimedStroke stk)

Paste to the bottom-center of the stroke. Override this method if you want.

handleDelete

protected void handleDelete(TimedStroke stk)

Delete whatever is in the center of the stroke (except ourself of course). Override this method if you want.

handleCenter

protected void handleCenter(TimedStroke stk)

Center the screen to be at the mark. Override this method if you want.

handleViewPort

protected void handleViewPort(String str,
                              TimedStroke stk)

Handle a move view port command. Override this method if you want.

getGraphicalObjectsTouching

protected GraphicalObjectCollection getGraphicalObjectsTouching(TimedStroke stk,
                                                                double thresh)

Get things that intersect the stroke. Override this method to change the behavior of how objects intersecting a stroke are selected. For example, in DENIM, this method is modified such that DenimPanel objects can be deleted when zoomed out (ie shallow), and strokes and phrases can be deleted when zoomed in (ie deep).

getGraphicalObjectCenteredAt

protected GraphicalObject getGraphicalObjectCenteredAt(TimedStroke stk)

Get the GraphicalObject near the center of this TimedStroke.

getGraphicalObjectCenteredAt

protected GraphicalObject getGraphicalObjectCenteredAt(TimedStroke stk,
                                                       double thresh)

Get the GraphicalObject near the center of this TimedStroke, with the specified threshold.

clone

public Object clone()

Description copied from class: InterpreterImpl

Since not overriding clone() can cause many errors with copying-and-pasting, I'm forcing you to do it. So there.

Overrides:

clone in class InterpreterImpl
