Field Detail

zero

java.awt.Point zero

The point defining the zero of the coordinate system. Set by paintComponent, usualy it is (firstX+30, lastY-20).
This coordinates are messured in pixels of the drawable area.

mouseIndexPos

java.awt.Point mouseIndexPos

Gives the actual position in the score and index array calculated from the mouse position over the paintable area. The x coordinate gives the index in the arrays and the y coordinate gives the height of the score.
It is updated by mouseMoved and initially set to (0,0) by the constructor.

paintStartIndex

int paintStartIndex

Set by method adjustmentValueChanged to give the start of the score vector, from which the plot is started to be painted.
This start point is messured in indices on the score and index arrays.

verticalStartIndex

int verticalStartIndex

Set by method adjustmentValueChanged to give the start on the y-axis in dots.

controller

ScorePlotBrowser controller

All changes are sent to the parent class, so this class can handle the events.

scrollBarH

javax.swing.JScrollBar scrollBarH

The horizontal scroll bar. All changes are handled within this class, despite the fact, that the scroll bar is not part of this component.

scrollBarV

javax.swing.JScrollBar scrollBarV

The vertical scroll bar. All changes are handled within this class, despite the fact, that the scroll bar is not part of this component.

preferredSize

java.awt.Dimension preferredSize

The preferred size of this component, set in the constructor.

Constructor Detail

ScorePlotBrowser.ScorePlotArea

ScorePlotBrowser.ScorePlotArea(ScorePlotBrowser controller,
                               javax.swing.JScrollBar scrollBarH,
                               javax.swing.JScrollBar scrollBarV)

Constructs the class by saving the reference to the controller.

Parameters:

controller - The controller class some events like mouse cursor changes are sent.

scrollBarH - The horizontal scroll bar which controls what part of the x-axis is drawn of the score plot.

scrollBarV - The vertical scroll bar which controls what part if the y-axis is drawn of the score plot.
