java.awt.Component

ptolemy.domains.ca.lib.gui.CAMatrixViewer

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

class CAMatrixViewer
extends java.awt.Component

The CAMatrixViewer is a type of Java Component that renders a grid of cells within a matrix (a two-dimensional array of doubles). A grid cell is rendered as 'on' if the value of the cell is greater than zero and 'off' otherwise. This class is not public and currently only used as part of a CATableau which, in turn, is used as part of a CADisplay.

Constructor Detail

CAMatrixViewer

public CAMatrixViewer()

Construct a new CAMatrixViewer and initialize the matrix to size [1][1] and set the only value to 1.0;

Method Detail

getMinimumSize

public java.awt.Dimension getMinimumSize()

Return the minimum size of this component.

Overrides:

getMinimumSize in class java.awt.Component

Returns:

The minimum size.

getPreferredSize

public java.awt.Dimension getPreferredSize()

Return the preferred size. The preferred size of this component is the minimum size.

Overrides:

getPreferredSize in class java.awt.Component

Returns:

the preferred size.

paint

public void paint(java.awt.Graphics graphics)

Paint the current matrix as a grid. If the value in a cell is greater than 0.0, then the cell is "filled-in."

Overrides:

paint in class java.awt.Component

Parameters:

graphics - The java Graphics object that is required to paint the Component.

setMatrix

public void setMatrix(double[][] matrix)

Set the matrix to display.

Parameters:

matrix - The matrix to display.
