Method Detail

addActionListener

public void addActionListener(java.awt.event.ActionListener listener)

Adds a listener to monitor action events (enter key events) on the PTextField.

Parameters:

listener - The listener to remove from this document. A null value will cause a NullPointerException.

getActionCommand

public java.lang.String getActionCommand()

Returns the action command associated with the enter key being pressed. A null value indicates thatthe text of the text field at the time of the event will be used. return The action command to be associated with the enter key.

setActionCommand

public void setActionCommand(java.lang.String actionCommand)

Sets the action command associated with the enter key being pressed.

Parameters:

actionCommand - The action command to be associated with the enter key. If null is passed, the text of the text field at the time of the event will be used.
