cz.fidentis.analyst.gui.elements.histogram.components.bounds.Bound

All Implemented Interfaces:

EventGenerator

public class Bound
extends EventDispatcher

Class for BoundComponents related logic. It connects them logically through a Bound.DragInputHandler that makes the components draggable along the X axis and provides other related convenient methods.

Dispatches ActionEvent with the following action commands:

• ACTION_COMMAND_BOUND_MOVED

Constructor Details

Bound

public Bound(BoundComponents boundComponents,
 FunctionScale positioningScale,
 int minPosition,
 int maxPosition)

Creates a Bound from given boundComponents and enables dragging. Zooming and panning on positioningScale automatically repositions boundComponent. Bound dragging is limited by minPosition and maxPosition.

Parameters:

boundComponents - bound component

positioningScale - scale for positioning

minPosition - minimal value this bound can have

maxPosition - maximal value this bound can have

• DragInputHandler

Method Details

getPosition

public int getPosition()

Get position of a Bound. Equal to BoundComponents.getPosition().

Returns:

position

See Also:

• Bound
• getRawPosition()

getRawPosition

public double getRawPosition()

Get the raw position of a Bound. A raw position is a projection of a position from range back to domain.

Returns:

raw position

See Also:

• Bound
• getPosition()

updatePosition

public void updatePosition()

Updates position of boundComponent. Update reacts primarily to changes made to positioningScale.

See Also:

• Bound

resetPosition

public void resetPosition()

Set the Bound value to its initial value at the time of instantiation.
