Constructor Details

AccessibleJTextComponent

public AccessibleJTextComponent()

Constructs an AccessibleJTextComponent. Adds a listener to track caret change.

Method Details

caretUpdate

public void caretUpdate(CaretEvent e)

Handles caret updates (fire appropriate property change event, which are AccessibleContext.ACCESSIBLE_CARET_PROPERTY and AccessibleContext.ACCESSIBLE_SELECTION_PROPERTY). This keeps track of the dot position internally. When the caret moves, the internal position is updated after firing the event.

Specified by:: caretUpdate in interface CaretListener
Parameters:: e - the CaretEvent

insertUpdate

public void insertUpdate(DocumentEvent e)

Handles document insert (fire appropriate property change event which is AccessibleContext.ACCESSIBLE_TEXT_PROPERTY). This tracks the changed offset via the event.

Specified by:: insertUpdate in interface DocumentListener
Parameters:: e - the DocumentEvent

removeUpdate

public void removeUpdate(DocumentEvent e)

Handles document remove (fire appropriate property change event, which is AccessibleContext.ACCESSIBLE_TEXT_PROPERTY). This tracks the changed offset via the event.

Specified by:: removeUpdate in interface DocumentListener
Parameters:: e - the DocumentEvent

changedUpdate

public void changedUpdate(DocumentEvent e)

Handles document remove (fire appropriate property change event, which is AccessibleContext.ACCESSIBLE_TEXT_PROPERTY). This tracks the changed offset via the event.

Specified by:: changedUpdate in interface DocumentListener
Parameters:: e - the DocumentEvent

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Gets the state set of the JTextComponent. The AccessibleStateSet of an object is composed of a set of unique AccessibleState's. A change in the AccessibleStateSet of an object will cause a PropertyChangeEvent to be fired for the AccessibleContext.ACCESSIBLE_STATE_PROPERTY property.

Overrides:

getAccessibleStateSet in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleStateSet containing the current state set of the object

See Also:

getAccessibleRole

public AccessibleRole getAccessibleRole()

Gets the role of this object.

Overrides:

getAccessibleRole in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleRole describing the role of the object (AccessibleRole.TEXT)

See Also:

getAccessibleText

public AccessibleText getAccessibleText()

Get the AccessibleText associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleText interface on behalf of itself.

Overrides:

getAccessibleText in class AccessibleContext

Returns:

this object

See Also:

getIndexAtPoint

public int getIndexAtPoint(Point p)

Given a point in local coordinates, return the zero-based index of the character under that Point. If the point is invalid, this method returns -1.

Specified by:: getIndexAtPoint in interface AccessibleText
Parameters:: p - the Point in local coordinates
Returns:: the zero-based index of the character under Point p.

getCharacterBounds

public Rectangle getCharacterBounds(int i)

Determines the bounding box of the character at the given index into the string. The bounds are returned in local coordinates. If the index is invalid a null rectangle is returned. The screen coordinates returned are "unscrolled coordinates" if the JTextComponent is contained in a JScrollPane in which case the resulting rectangle should be composed with the parent coordinates. A good algorithm to use is:

Accessible a:
AccessibleText at = a.getAccessibleText();
AccessibleComponent ac = a.getAccessibleComponent();
Rectangle r = at.getCharacterBounds();
Point p = ac.getLocation();
r.x += p.x;
r.y += p.y;

Note: the JTextComponent must have a valid size (e.g. have been added to a parent container whose ancestor container is a valid top-level window) for this method to be able to return a meaningful (non-null) value.

Specified by:: getCharacterBounds in interface AccessibleText
Parameters:: i - the index into the String ≥ 0
Returns:: the screen coordinates of the character's bounding box

Returns:: the zero-based offset of the caret.

getCharacterAttribute

public AttributeSet getCharacterAttribute(int i)

Returns the AttributeSet for a given character (at a given index).

Specified by:: getCharacterAttribute in interface AccessibleText
Parameters:: i - the zero-based index into the text
Returns:: the AttributeSet of the character

getSelectionEnd

public int getSelectionEnd()
