Class ClickBTDisplay.VScaleManager

java.lang.Object
  clickDetector.ClickBTDisplay.VScaleManager

All Implemented Interfaces:

java.awt.event.AdjustmentListener, java.util.EventListener

Direct Known Subclasses:

ClickBTDisplay.AmplitudeScaleManager, ClickBTDisplay.BearingScaleManager, ClickBTDisplay.ICIScaleManager

Enclosing class:

ClickBTDisplay

abstract class ClickBTDisplay.VScaleManager
extends java.lang.Object
implements java.awt.event.AdjustmentListener

Class for managing vertical scales and scrolls which will either be bearing, ICI or Amplitude.

Jobs this beast has to do are:

set up the scroll bar at start and after a zoom

set the yStart and yScale values whatever the zoom state

write the correct values and titles on the y axis.

setSelected

public void setSelected()

getCoordinateType

public abstract int getCoordinateType()

checkNoZoom

public boolean checkNoZoom()

Check for there being no zooms in this coordinate frame

If there was no zoom, restore defaults and return true.

Returns:

true if there were no zooms, and false otherwise

getLastZoom

setupScrollBar

public void setupScrollBar(double start,
                           double page)

valueToScroll

public abstract int valueToScroll(double value,
                                  int visAmount)

convert a value to a scroll bar position

Parameters:

value - value to convert

visAmount - visible amount of scroll br

Returns:

new scroll bar position

scrollToValue

public abstract double scrollToValue(int scrollPos)

Convert a scroll bar position back into avalue.

Parameters:

scrollPos - scroll position

Returns:

new value

getStep

public abstract double getStep()

Get unit step for scroll bar (e.g. 0.1 if you want a bearing scroll to be in 1/10 degree steps).

Returns:

unit step

getMin

public abstract double getMin()

Returns:

the maximum value for the scroll bar

getMax

public abstract double getMax()

Returns:

the minimum value for the scroll bar

getCurrentStart

getCurrentRange

public double getCurrentRange()

the range from the bottom to the top of the display (may be negative if top of display has smaller values than bottom)

Returns:

range

getCurrentEnd

public double getCurrentEnd()

Value at the top of the display

Returns:

getTitle

public abstract java.lang.String getTitle()

Returns:

Title to use in the display axis.

adjustmentValueChanged
