Constructor Detail

TextAreaControl

public TextAreaControl()
Constructor.

Method Detail

setMaxCharacters

public void setMaxCharacters(int maxCharacters)
Set maximum number of characters.

Parameters:
maxCharacters - maximum number of characters

getMaxCharacters

public int getMaxCharacters()
Returns:
maximum number of characters

setText

public final void setText(java.lang.String text)

setEnabled

public void setEnabled(boolean enabled)
Replace enabled setting with editable setting (this allow tab swithing).

Specified by:
setEnabled in interface InputControl
Overrides:
setEnabled in class BaseInputControl
Parameters:
enabled - flag used to set abilitation of control

isEnabled

public final boolean isEnabled()
Specified by:
isEnabled in interface InputControl
Overrides:
isEnabled in class BaseInputControl
Returns:
current input control abilitation

getTextArea

public final javax.swing.JTextArea getTextArea()
Returns:
text editor

getBindingComponent

public javax.swing.JComponent getBindingComponent()
Overrides:
getBindingComponent in class BaseInputControl
Returns:
component inside this whose contains the value

getValue

public java.lang.Object getValue()
Specified by:
getValue in interface InputControl
Overrides:
getValue in class BaseInputControl
Returns:
value related to the input control

setValue

public void setValue(java.lang.Object value)
Set value to the input control.

Specified by:
setValue in interface InputControl
Overrides:
setValue in class BaseInputControl
Parameters:
value - value to set into the input control

setTextOrientation

public final void setTextOrientation(java.awt.ComponentOrientation o)
Set the component orientation: from left to right or from right to left.

Parameters:
o - component orientation

getTextOrientation

public final java.awt.ComponentOrientation getTextOrientation()
Returns:
component orientation

addFocusListener

public final void addFocusListener(java.awt.event.FocusListener listener)
Adds the specified focus listener to receive focus events from this component when this component gains input focus. If listener l is null, no exception is thrown and no action is performed.

Specified by:
addFocusListener in interface InputControl
Since:
JDK1.1
See Also:
FocusEvent, FocusListener, removeFocusListener(java.awt.event.FocusListener), Component.getFocusListeners()

removeFocusListener

public final void removeFocusListener(java.awt.event.FocusListener listener)
Removes the specified focus listener so that it no longer receives focus events from this component. This method performs no function, nor does it throw an exception, if the listener specified by the argument was not previously added to this component. If listener l is null, no exception is thrown and no action is performed.

Specified by:
removeFocusListener in interface InputControl
Since:
JDK1.1
See Also:
FocusEvent, FocusListener, addFocusListener(java.awt.event.FocusListener), Component.getFocusListeners()

processKeyEvent

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

select

public final void select(int selectionStart,
                         int selectionEnd)
Selects the text between the specified start and end positions.

This method sets the start and end positions of the selected text, enforcing the restriction that the start position must be greater than or equal to zero. The end position must be greater than or equal to the start position, and less than or equal to the length of the text component's text.

If the caller supplies values that are inconsistent or out of bounds, the method enforces these constraints silently, and without failure. Specifically, if the start position or end position is greater than the length of the text, it is reset to equal the text length. If the start position is less than zero, it is reset to zero, and if the end position is less than the start position, it is reset to the start position.

This call is provided for backward compatibility. It is routed to a call to setCaretPosition followed by a call to moveCaretPosition. The preferred way to manage selection is by calling those methods directly.

Parameters:
selectionStart - the start position of the text
selectionEnd - the end position of the text
