All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.event.ActionListener, java.awt.event.AdjustmentListener, java.util.EventListener, java.awt.image.ImageObserver, java.awt.event.ItemListener, java.awt.MenuContainer, PsUpdateIf, java.io.Serializable

public class PdArray_IP

extends PsPanel

implements java.awt.event.ActionListener, java.awt.event.AdjustmentListener, java.awt.event.ItemListener

Info panel for array of double vectors, each having horizontal value fields. On the left side is a vertical scrollbar to allow scrolling through vectors. Numbers with absolute value less than EPS are shown as zero. This avoids the anoying fact that double precision numbers fill the whole text area hiding the exponent, which hides their small value.

Version:

21.12.99, 1.30 revised (kp) Handling of arrays with vectors of different length improved.
22.08.99, 1.20 revised (kp) Number with abs value less than PuMath.EPS are shown as zero.
07.08.99, 1.10 revised (kp) Converted to AWT 1.1
00.00.97, 1.00 created (kp)

Constructor Detail

PdArray_IP

public PdArray_IP(int visibleVectors,
                  int visibleDim)

Method Detail

init

public void init()

Overrides:

init in class PsPanel

setNumOfEntries

public boolean setNumOfEntries(int num,
                               int dim)

Set the dimension of visible array of text fields. If a parameter value is -1 then the default maximal values of this class are used.

Parameters:

num - number of rows in array

dim - number of columns in array

Returns:

Currently, always true.

setVector

public void setVector(PdVector[] vector,
                      java.lang.String[] header,
                      int numVectors,
                      int dim)

setParent

public void setParent(PsUpdateIf parent)

Description copied from interface: PsUpdateIf

Set parent and do nothing else. Method is implemented by PsObject and PsPanel, and should be called if overwritten.

Overrides:

setParent in class PsPanel

Following copied from interface: jv.object.PsUpdateIf

Parameters:

aParent - will receive events which this does not handle

See Also:

PsUpdateIf.getFather(), PsUpdateIf.update(Object)

update

public boolean update(java.lang.Object anObject)

Called from parent only if vertex coordinates have changed and they must be updated in this panel. If number of vertices etc. have changed then parent must call setVector() instead. During initialization parent must call update(this) and setVector().

Overrides:

update in class PsPanel

Following copied from interface: jv.object.PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

PsObject, PsUpdateIf.getFather(), PsUpdateIf.setParent(PsUpdateIf)

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent event)

Specified by:

adjustmentValueChanged

public void adjustmentValueChanged(java.awt.event.AdjustmentEvent event)

Specified by:

adjustmentValueChanged in interface java.awt.event.AdjustmentListener

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent event)

Specified by:
