Method Detail

dragComplete

public void dragComplete(boolean success)

Description copied from class: DrawHandle

Called when the user has completed dragging (e.g. on mouse-button-release.) It is appropriate to add an undo event.

Overrides:

dragComplete in class DrawHandle

Parameters:

success - Whether the action was successful (and therefore should be stored in the UNDO history).

getCenterPoint

public SelectionRotater.CenterPoint getCenterPoint()

getCompletionEvent

public SceneUpdateInfo getCompletionEvent()

Specified by:

getCompletionEvent in class DrawHandle

isValid

public boolean isValid()

Specified by:

isValid in class DrawHandle

nucPositionsChanged

protected void nucPositionsChanged()

Description copied from class: DrawHandle

Called when any nucleotides in the scene changed position, EXCEPT when THIS DrawHandle is in the middle of a performDrag operation (because any nucleotide changes then are likely due to its own drag operation).

Specified by:

nucPositionsChanged in class DrawHandle

performDrag

protected void performDrag(java.awt.Point start,
                           java.awt.Point prev,
                           java.awt.Point current,
                           SceneController.DragOpts options)

Called when this handle has been dragged by the user.

Specified by:

performDrag in class DrawHandle

prepareDraw

protected void prepareDraw(boolean isDragging)

Specified by:

prepareDraw in class DrawHandle

resetLocation

void resetLocation()

selectionChanged

protected void selectionChanged()

Specified by:

selectionChanged in class DrawHandle

setSelection

public void setSelection(Nuc focus,
                         java.util.Collection<Nuc> selection)

Overrides:

setSelection in class DrawHandle
