All Implemented Interfaces:

java.awt.event.FocusListener, java.awt.event.KeyListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class UDCIPAddressField
extends javax.swing.JPanel
implements java.awt.event.KeyListener, java.awt.event.FocusListener

A Component which allows for the entry of an IP address. It consists of a panel containing 4 JTextFields. Each textfield will only accept numeric values between 0 and 255. Focus will automatically shift to the next field when it can be determined that the user has entered a valid value for that field.

Constructor Detail

UDCIPAddressField

public UDCIPAddressField()

Initializes component with an IP Address of 0.0.0.0

UDCIPAddressField

public UDCIPAddressField(java.lang.String ip)

Initializes component with an IP Address of 0.0.0.0

UDCIPAddressField

public UDCIPAddressField(java.lang.String ip,
                         int columns)

UDCIPAddressField

public UDCIPAddressField(int columns)

Method Detail

getText

public java.lang.String getText()

Returns the contents of the text fields as an IP Address using dot-notation, Example : 127.0.0.1

setText

public void setText(java.lang.String s)

Parses the given String as an IP Address and puts the bytes in the appropriate text fields. Partial IP addresses may be specified, such as "121.33" or "...100"

getByteValue

public int getByteValue(int pos)

Returns the value of the byte in the given position(1-4).

Returns:

If pos is out of range, -1 will be returned.

setByteValue

public void setByteValue(int pos,
                         int value)

Sets the value of the byte in the given position(1-4). If pos is out of range, nothing is done.

setEnabled

public void setEnabled(boolean b)

Overrides:

setEnabled in class javax.swing.JComponent

setEditable

public void setEditable(boolean b)

focusGained

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

Called when one of the text fields gains focus. All text is selected so the user can just overwrite the present value quickly.

Specified by:

focusGained in interface java.awt.event.FocusListener

focusLost

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

Called when one of the text fields loses focus. If the field is left blank, the contents will be replaced with "0".

Specified by:

focusLost in interface java.awt.event.FocusListener

keyTyped

public void keyTyped(java.awt.event.KeyEvent e)

Specified by:

keyTyped in interface java.awt.event.KeyListener

keyPressed

public void keyPressed(java.awt.event.KeyEvent e)

Specified by:

keyPressed in interface java.awt.event.KeyListener

setColumns

public void setColumns(int i)

Set the column width of the editable text fields.

keyReleased

public void keyReleased(java.awt.event.KeyEvent e)

Determines whether focus should leave the current text field.

Specified by:

keyReleased in interface java.awt.event.KeyListener
