Makes this Component displayable by connecting it to a native screen resource. This method is called internally by the toolkit and should not be called directly by programs.

removeNotify

Adds the specified text event listener to receive text events from this text component. If l is null, no exception is thrown and no action is performed.

Refer to AWT Threading Issues for details on AWT's threading model.

l	the text event listener
See also	removeTextListener, getTextListeners, java.awt.event.TextListener

Enables or disables input method support for this text component. If input method support is enabled and the text component also processes key events, incoming events are offered to the current input method and will only be processed by the component or dispatched to its listeners if the input method does not consume them. Whether and how input method support for this text component is enabled or disabled by default is implementation dependent.

enable	true to enable, false to disable

Returns a string representing the state of this TextComponent. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

return

the parameter string of this text component

Processes events on this text component. If the event is a TextEvent, it invokes the processTextEvent method else it invokes its superclass's processEvent.

Note that if the event parameter is null the behavior is unspecified and may result in an exception.

e

the event

Processes text events occurring on this text component by dispatching them to any registered TextListener objects.

NOTE: This method will not be called unless text events are enabled for this component. This happens when one of the following occurs:

• A TextListener object is registered via addTextListener
• Text events are enabled via enableEvents

Note that if the event parameter is null the behavior is unspecified and may result in an exception.

e	the text event
See also	enableEvents

Removes the specified text event listener so that it no longer receives text events from this text component If l is null, no exception is thrown and no action is performed.

Refer to AWT Threading Issues for details on AWT's threading model.

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. The character positions are indexed starting with zero. The length of the selection is endPosition - startPosition, so the character at endPosition is not selected. If the start and end positions of the selected text are equal, all text is deselected.

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.

selectionStart	the zero-based index of the first character (char value) to be selected
selectionEnd	the zero-based end position of the text to be selected; the character (char value) at selectionEnd is not selected
See also	setSelectionStart, setSelectionEnd, selectAll

Selects all the text in this text component.

Gets the AccessibleContext associated with this TextComponent. For text components, the AccessibleContext takes the form of an AccessibleAWTTextComponent. A new AccessibleAWTTextComponent instance is created if necessary.

return	an AccessibleAWTTextComponent that serves as the AccessibleContext of this TextComponent
since	1.3

Sets the background color of this text component.

c	The color to become this text component's color. If this parameter is null then this text component will inherit the background color of its parent.
since	JDK1.0
See also	getBackground()

Gets the background color of this text component. By default, non-editable text components have a background color of SystemColor.control. This default can be overridden by calling setBackground.

return	This text component's background color. If this text component does not have a background color, the background color of its parent is returned.
since	JDK1.0
See also	setBackground(Color)

Sets the position of the text insertion caret. The caret position is constrained to be between 0 and the last character of the text, inclusive. If the passed-in value is greater than this range, the value is set to the last character (or 0 if the TextComponent contains no text) and no error is returned. If the passed-in value is less than 0, an IllegalArgumentException is thrown.

position	the position of the text insertion caret
Throws	IllegalArgumentException: if position is less than zero
since	JDK1.1

Returns the position of the text insertion caret. The caret position is constrained to be between 0 and the last character of the text, inclusive. If the text or caret have not been set, the default caret position is 0.

return	the position of the text insertion caret
since	JDK1.1
See also	setCaretPosition(int)

Sets the flag that determines whether or not this text component is editable.

If the flag is set to true, this text component becomes user editable. If the flag is set to false, the user cannot change the text of this text component. By default, non-editable text components have a background color of SystemColor.control. This default can be overridden by calling setBackground.

b	a flag indicating whether this text component is user editable.
since	JDK1.0
See also	isEditable

Indicates whether or not this text component is editable.

return	true if this text component is editable; false otherwise.
since	JDK1.0

Returns an array of all the objects currently registered as FooListeners upon this TextComponent. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a TextComponent t for its text listeners with the following code:

TextListener[] tls = (TextListener[])(t.getListeners(TextListener.class));

If no such listeners exist, this method returns an empty array.

listenerType	the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
return	an array of all objects registered as FooListeners on this text component, or an empty array if no such listeners have been added
Throws	ClassCastException: if listenerType doesn't specify a class or interface that implements java.util.EventListener
since	1.3

Returns the selected text from the text that is presented by this text component.

return	the selected text of this text component

Sets the selection end for this text component to the specified position. The new end point is constrained to be at or after the current selection start. It also cannot be set beyond the end of the component's text. If the caller supplies a value for selectionEnd that is out of bounds, the method enforces these constraints silently, and without failure.

selectionEnd	the end position of the selected text
since	JDK1.1
See also	getSelectionEnd, setSelectionStart

Gets the end position of the selected text in this text component.

return	the end position of the selected text
See also	setSelectionEnd, getSelectionStart

Sets the selection start for this text component to the specified position. The new start point is constrained to be at or before the current selection end. It also cannot be set to less than zero, the beginning of the component's text. If the caller supplies a value for selectionStart that is out of bounds, the method enforces these constraints silently, and without failure.

selectionStart	the start position of the selected text
since	JDK1.1

Gets the start position of the selected text in this text component.

return	the start position of the selected text

Sets the text that is presented by this text component to be the specified text.

t	the new text; if this parameter is null then the text is set to the empty string ""

Returns the text that is presented by this text component. By default, this is an empty string.

return	the value of this TextComponent

Returns an array of all the text listeners registered on this text component.
