Constructor Details

AccessibleAbstractButton

protected AccessibleAbstractButton()
The default constructor.

Method Details

doAccessibleAction

public boolean doAccessibleAction(int value0)
Specified by:
doAccessibleAction in interface AccessibleAction

getAccessibleAction

public AccessibleAction getAccessibleAction()
Get any supported accessible actions. The default implementation returns null.
Overrides:
getAccessibleAction in interface AccessibleContext
Returns:
the supported action, or null

getAccessibleActionCount

public int getAccessibleActionCount()
Specified by:
getAccessibleActionCount in interface AccessibleAction

getAccessibleActionDescription

public String getAccessibleActionDescription(int value0)
Specified by:
getAccessibleActionDescription in interface AccessibleAction

getAccessibleIcon

public AccessibleIcon[] getAccessibleIcon()
Get all supported accessible icons. The default implementation returns null.
Overrides:
getAccessibleIcon in interface AccessibleContext
Returns:
the supported icons, or null

getAccessibleName

public String getAccessibleName()
Returns the accessible name of this component. It is almost always wrong to return getName(), since it is not localized. In fact, for things like buttons, this should be the text of the button, not the name of the object. The tooltip text might also be appropriate.
Overrides:
getAccessibleName in interface JComponent.AccessibleJComponent
Returns:
the name

getAccessibleRelationSet

public AccessibleRelationSet getAccessibleRelationSet()
Get any supported accessible relation set. The default implementation returns null.
Overrides:
getAccessibleRelationSet in interface AccessibleContext
Returns:
the supported relation set, or null

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()
Returns a state set describing this component's state.
Overrides:
getAccessibleStateSet in interface JComponent.AccessibleJComponent
Returns:
a new state set

getAccessibleText

public AccessibleText getAccessibleText()
Get any supported accessible text. The default implementation returns null.
Overrides:
getAccessibleText in interface AccessibleContext
Returns:
the supported text, or null

getAccessibleValue

public AccessibleValue getAccessibleValue()
Get any supported accessible value. The default implementation returns null.
Overrides:
getAccessibleValue in interface AccessibleContext
Returns:
the supported value, or null

getAfterIndex

public String getAfterIndex(int value0,
                            int value1)
Returns the section of text after the index, or null if the index or part is invalid.
Specified by:
getAfterIndex in interface AccessibleText
Parameters:
Returns:
the selection of text after that index, or null

getAtIndex

public String getAtIndex(int value0,
                         int value1)
Returns the section of text at the index, or null if the index or part is invalid.
Specified by:
getAtIndex in interface AccessibleText
Parameters:
Returns:
the selection of text at that index, or null

getBeforeIndex

public String getBeforeIndex(int value0,
                             int value1)
Returns the section of text before the index, or null if the index or part is invalid.
Specified by:
getBeforeIndex in interface AccessibleText
Parameters:
Returns:
the selection of text before that index, or null

getCaretPosition

public int getCaretPosition()
Return the offset of the character. The offset matches the index of the character to the right, since the carat lies between characters.
Specified by:
getCaretPosition in interface AccessibleText
Returns:
the 0-based caret position

getCharCount

public int getCharCount()
Return the number of characters.
Specified by:
getCharCount in interface AccessibleText
Returns:
the character count

getCharacterAttribute

Specified by:
getCharacterAttribute in interface AccessibleText
Parameters:
Returns:
the character's attributes

getCharacterBounds

public Rectangle getCharacterBounds(int value0)
Determines the bounding box of the indexed character. Returns an empty rectangle if the index is out of bounds.
Specified by:
getCharacterBounds in interface AccessibleText
Parameters:
Returns:
the bounding box, may be empty

getCurrentAccessibleValue

public Number getCurrentAccessibleValue()
Specified by:
getCurrentAccessibleValue in interface AccessibleValue

getIndexAtPoint

public int getIndexAtPoint(Point value0)
Given a point in the coordinate system of this object, return the 0-based index of the character at that point, or -1 if there is none.
Specified by:
getIndexAtPoint in interface AccessibleText
Parameters:
Returns:
the character index, or -1

getMaximumAccessibleValue

public Number getMaximumAccessibleValue()
Specified by:
getMaximumAccessibleValue in interface AccessibleValue

getMinimumAccessibleValue

public Number getMinimumAccessibleValue()
Specified by:
getMinimumAccessibleValue in interface AccessibleValue

getSelectedText

public String getSelectedText()
Returns the selected text. This may be null or "" if no text is selected.
Specified by:
getSelectedText in interface AccessibleText
Returns:
the selected text

getSelectionEnd

public int getSelectionEnd()
Returns the end index of the selection. If there is no selection, this is the same as the caret location.
Specified by:
getSelectionEnd in interface AccessibleText
Returns:
the 0-based character index of the selection end

getSelectionStart

public int getSelectionStart()
Returns the start index of the selection. If there is no selection, this is the same as the caret location.
Specified by:
getSelectionStart in interface AccessibleText
Returns:
the 0-based character index of the selection start

setCurrentAccessibleValue

public boolean setCurrentAccessibleValue(Number value0)
Specified by:
setCurrentAccessibleValue in interface AccessibleValue
