public class JpasswordField

extends javax.swing.JPasswordField

implements java.awt.event.KeyListener

This class defines an entry field that is capable of handling strings. It is also possible to restrict the characters which are accepted by this gui component. Furthermore, the maximum size of the string that can be entered into this JstringField can be preset.

Constructor Detail

JpasswordField

public JpasswordField(int columns,
                      int maxstrlen,
                      boolean is_editable,
                      boolean invisible,
                      java.lang.String allowed,
                      java.lang.String disallowed)

Base constructor for JpasswordField

Parameters:

columns - number of colums in the JpasswordField

is_editable - true if this JpasswordField is editable

public JpasswordField()

Constructor which uses default fonts,no parent, default column size, and default foregound/background colors.

JpasswordField

public JpasswordField(int cols,
                      boolean is_editable)

Simple constructor.

JpasswordField

public JpasswordField(int cols,
                      int maxstrlen,
                      boolean is_editable,
                      boolean invisible,
                      java.lang.String allowed,
                      java.lang.String disallowed,
                      arlut.csd.JDataComponent.JsetValueCallback callback)

Constructor that allows for the creation of a JpasswordField that knows about its parent.

Parameters:

cols - number of colums in the JpasswordField

Method Detail

isChanged

public boolean isChanged()

setCallback

public void setCallback(arlut.csd.JDataComponent.JsetValueCallback parent)

sets the parent of this component for callback purposes

setText

public void setText(java.lang.String str)

sets the JpasswordField to a specific value

Overrides:

setText in class javax.swing.text.JTextComponent

Parameters:

str - value to which the JpasswordField is set

getValue

public java.lang.String getValue()

returns the value of the member variable value

getCharAt

public char getCharAt(int n)

returns the character located at position n in the JpasswordField value

Parameters:

n - position in the JpasswordField value from which to retrieve character

setAllowedChars

public void setAllowedChars(java.lang.String s)

assigns a set of characters which are valid within the JpasswordField

Parameters:

s - each character in this string will be considered an allowed character

setDisallowedChars

public void setDisallowedChars(java.lang.String s)

assigns a set of characters which are invalid within the JpasswordField

Parameters:

s - each character in this string will be considered a disallowed character

getAllowedChars

public java.lang.String getAllowedChars()

returns the set of allowed characters as a String object

getDisallowedChars

public java.lang.String getDisallowedChars()

returns the set of disallowed characters as a String object

getMaxStringSize

public int getMaxStringSize()

returns the maximum size of the string that can be placed in this JpasswordField

isAllowed

private boolean isAllowed(char ch)

determines whether a given character is valid or invalid for a JpasswordField

Parameters:

ch - the character which is being tested for its validity

processFocusEvent

public void processFocusEvent(java.awt.event.FocusEvent e)

When the JpasswordField looses focus, any changes made to the value in the JpasswordField need to be propogated to the server. This method will handle that functionality. This method is synchronized to prevent overlapping callbacks if we are in a threaded environment.

Overrides:

processFocusEvent in class java.awt.Component

Parameters:

e - the FocusEvent that needs to be process
