Constructor Detail

EditElementMouseTransformFactory._MoveElementTransform

public EditElementMouseTransformFactory._MoveElementTransform(BranchElement target,
                                                              int anchorChildIndex,
                                                              PicPoint clickPt,
                                                              Grid grid)

Parameters:

target - the selection-handler upon which this transform acts (globally)

anchorChildIndex - index of target's child that will serve as the reference-child for grid alignment ; if null, target is used instead ;

clickPt -

Method Detail

start

public void start(PEMouseEvent e)

Called when the mouse is pressed.
Create a clone of the clickedElement given as the parameter in the constructor.

Specified by:

start in interface MouseTransform

Overrides:

start in class AbstractMouseTransform

getCursor

public Cursor getCursor()

Description copied from interface: MouseTransform

Return the cursor for this MouseTransform

Returns:

a Cursor whose type is adequate with this mouse-transform.

process

public void process(PEMouseEvent me)

Called when the mouse is dragged.

next

public boolean next(PEMouseEvent e)

Description copied from class: AbstractMouseTransform

Called by mouseReleased.
This implementation set the clone's parent and view to null so as to make it elligible for gc. This should be called by subclassers at the end of the implementation of their "next" method.

Specified by:

next in interface MouseTransform

Overrides:

next in class AbstractMouseTransform

Returns:

true if there's another task in the sequence, false if mouse-transform has completed with this mouse-event.

getHelpMessage

public String getHelpMessage()

Description copied from interface: MouseTransform

Return a help-message for the UI, that makes sense with this transform.

Returns:

a help-message for the UI, that makes sense with this transform.

toString

public String toString()

Overrides:

toString in class Object
