Imports
impl.org.controlsfx.tools.rectangle.Edge2D, .Rectangles2D, javafx.geometry.Point2D, .Rectangle2D
Abstract superclass to those implementations of Rectangle2DChangeStrategy which compute their rectangle by spanning it from a fixed edge to the parallel edge defined by the point given to continueChange.
The edge is fixed during the change but can be changed in between changes. Implemented such that a ratio is respected if specified.

Field Summary

Modifier and TypeField and Description
private final Rectangle2D
bounds

A rectangle which defines the bounds within which the new rectangle must be contained.

private Edge2D
fixedEdge

The edge which is fixed during the change.

Constructor Summary

AccessConstructor and Description
protected
AbstractFixedEdgeChangeStrategy(boolean
indicates whether the ratio will be fixed
ratioFixed, double
defines the fixed ratio
ratio, Rectangle2D

bounds)

Creates a fixed edge change strategy.

Method Summary

Modifier and TypeMethod and Description
private final Rectangle2D

Returns:

the rectangle defined the two edges
createFromEdges(Point2D
the point defining the parallel edge
point)

Creates a new rectangle from the two edges defined by fixedEdge and its parallel through the specified point.

protected final Rectangle2D
doBegin(Point2D point)

Implements abstract impl.org.controlsfx.tools.rectangle.change.AbstractBeginEndCheckingChangeStrategy.doBegin.

Begins the change at the specified point.

protected Rectangle2D
doContinue(Point2D point)

Implements abstract impl.org.controlsfx.tools.rectangle.change.AbstractBeginEndCheckingChangeStrategy.doContinue.

Continues the change to the specified point.

protected final Rectangle2D
doEnd(Point2D point)

Implements abstract impl.org.controlsfx.tools.rectangle.change.AbstractBeginEndCheckingChangeStrategy.doEnd.

Ends the change at the specified point.

protected abstract Edge2D

Returns:

the edge which is fixed during the change
getFixedEdge()

Returns the edge which is fixed during the change.

Field Detail

boundsback to summary
private final Rectangle2D bounds

A rectangle which defines the bounds within which the new rectangle must be contained.

fixedEdgeback to summary
private Edge2D fixedEdge

The edge which is fixed during the change. In doBegin(Point2D) it is set to getFixedEdge(); in doEnd(Point2D) it is set to null.

Constructor Detail

AbstractFixedEdgeChangeStrategyback to summary
protected AbstractFixedEdgeChangeStrategy(boolean ratioFixed, double ratio, Rectangle2D bounds)

Creates a fixed edge change strategy. It respects the specified ratio if ratioFixed is true.

Parameters
ratioFixed:boolean

indicates whether the ratio will be fixed

ratio:double

defines the fixed ratio

bounds:Rectangle2D

the bounds within which the new rectangle must be contained

Method Detail

createFromEdgesback to summary
private final Rectangle2D createFromEdges(Point2D point)

Creates a new rectangle from the two edges defined by fixedEdge and its parallel through the specified point.

Parameters
point:Point2D

the point defining the parallel edge

Returns:Rectangle2D

the rectangle defined the two edges
