Field Detail

graphComponent

protected mxGraphComponent graphComponent

Reference to the enclosing graph instance.

steps

protected int steps

Specifies the maximum number of steps for the morphing. Default is 6.

step

protected int step

Counts the current number of steps of the animation.

ease

protected double ease

Ease-off for movement towards the given vector. Larger values are slower and smoother. Default is 1.5.

origins

protected Map<Object,mxPoint> origins

Maps from cells to origins.

cells

protected Object[] cells

Optional array of cells to limit the animation to.

dirty

protected transient mxRectangle dirty

preview

protected transient mxCellStatePreview preview

Constructor Detail

mxMorphing

public mxMorphing(mxGraphComponent graphComponent)

Constructs a new morphing instance for the given graph.

mxMorphing

public mxMorphing(mxGraphComponent graphComponent,
                  int steps,
                  double ease,
                  int delay)

Constructs a new morphing instance for the given graph.

Method Detail

getSteps

public int getSteps()

Returns the number of steps for the animation.

setSteps

public void setSteps(int value)

Sets the number of steps for the animation.

getEase

public double getEase()

Returns the easing for the movements.

setEase

public void setEase(double value)

Sets the easing for the movements.

setCells

public void setCells(Object[] value)

Optional array of cells to be animated. If this is not specified then all cells are checked and animated if they have been moved in the current transaction.

updateAnimation

Overrides:

updateAnimation in class mxAnimation

stopAnimation

public void stopAnimation()

Description copied from class: mxAnimation

Stops the animation by deleting the timer and fires mxEvent.DONE.

Overrides:

stopAnimation in class mxAnimation

show

animateCell

protected void animateCell(Object cell,
                           mxCellStatePreview move,
                           boolean recurse)

stopRecursion

protected boolean stopRecursion(mxCellState state,
                                mxPoint delta)

Returns true if the animation should not recursively find more deltas for children if the given parent state has been animated.

getDelta

protected mxPoint getDelta(mxCellState state)

Returns the vector between the current rendered state and the future location of the state after the display will be updated.

getOriginForCell

protected mxPoint getOriginForCell(Object cell)

Returns the top, left corner of the given cell.
