Constructor Detail

BasicParallelDisplayUI

public BasicParallelDisplayUI()

Default Constructor. Creates a new BasicParallelDisplayUI.

Method Detail

createUI

public static javax.swing.plaf.ComponentUI createUI(javax.swing.JComponent c)

Swing method. Returns a new instance.

installUI

public void installUI(javax.swing.JComponent c)

Installs this instance as UI delegate for the given component.

Parameters:

c - The component, a ParallelDisplay in our case.

uninstallUI

public void uninstallUI(javax.swing.JComponent c)

Uninstalls this instance from its component.

Parameters:

c - The component, a ParallelDisplay in our case.

paint

public void paint(java.awt.Graphics g,
                  javax.swing.JComponent c)

Renders the component on the screen.

Parameters:

g - The graphics object to draw on.

c - The Component, our ParallelDisplay.

renderBrush

public void renderBrush()

Specified by:

mouseExited in interface java.awt.event.MouseListener

Parameters:

e - The mouse event.

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

Invoked when a mouse button has been released on a component. Checks if something has been dragged and finishes the drag process.

public void createBrushImage(ParallelDisplay comp)

Specified by:

createBrushImage in class ParallelDisplayUI

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

Invoked when a mouse button is pressed on a component and then dragged. Mouse drag events will continue to be delivered to the component where the first originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component). Depending on the current mode, this method performs scaling, translating or reordering of axes.

mouseDragged in interface java.awt.event.MouseMotionListener

Parameters:

e - The mouse event.

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

Invoked when the mouse has been clicked on a component. Checks if the click hit an arrow and inverts the corresponding axis.

Specified by:

mouseClicked in interface java.awt.event.MouseListener

Parameters:

e - The mouse event.

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent e)

Invoked when the mouse enters a component.

Specified by:

mouseEntered in interface java.awt.event.MouseListener

setHoverRecord

public void setHoverRecord(int record,
                           ParallelDisplay comp)

Added by Frank Hardisty 19 July 2002 This method is called to create a hover record from outside the component

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent e)

Invoked when the mouse button has been moved on a component (with no buttons no down). Displays tooltips if mouse is hovering over axes or records.

Specified by:

Parameters:

x - The x screen coordinate.

y - The y screen coordinate.

comp - The "parent" component.

Returns:

The recordnumber of the first record found passing through the given point.

getAllRecordsByCoordinates

public int[] getAllRecordsByCoordinates(java.awt.geom.Rectangle2D hitBox,
                                        ParallelDisplay comp)
