public interface AccessibleComponent
AccessibleComponent
interface should be supported by any object that is rendered on the screen. This interface provides the standard mechanism for an assistive technology to determine and set the graphical representation of an object. Applications can determine if an object supports the AccessibleComponent
interface by first obtaining its AccessibleContext
and then calling the AccessibleContext.getAccessibleComponent()
method. If the return value is not null
, the object supports this interface.Modifier and Type | Method | Description |
---|---|---|
void |
addFocusListener |
Adds the specified focus listener to receive focus events from this component. |
boolean |
contains |
Checks whether the specified point is within this object's bounds, where the point's x and y coordinates are defined to be relative to the coordinate system of the object. |
Accessible |
getAccessibleAt |
Returns the Accessible child, if one exists, contained at the local coordinate Point . |
Color |
getBackground() |
Gets the background color of this object. |
Rectangle |
getBounds() |
Gets the bounds of this object in the form of a Rectangle object. |
Cursor |
getCursor() |
Gets the cursor of this object. |
Font |
getFont() |
Gets the font of this object. |
FontMetrics |
getFontMetrics |
Gets the FontMetrics of this object. |
Color |
getForeground() |
Gets the foreground color of this object. |
Point |
getLocation() |
Gets the location of the object relative to the parent in the form of a point specifying the object's top-left corner in the screen's coordinate space. |
Point |
getLocationOnScreen() |
Returns the location of the object on the screen. |
Dimension |
getSize() |
Returns the size of this object in the form of a Dimension object. |
boolean |
isEnabled() |
Determines if the object is enabled. |
boolean |
isFocusTraversable() |
Returns whether this object can accept focus or not. |
boolean |
isShowing() |
Determines if the object is showing. |
boolean |
isVisible() |
Determines if the object is visible. |
void |
removeFocusListener |
Removes the specified focus listener so it no longer receives focus events from this component. |
void |
requestFocus() |
Requests focus for this object. |
void |
setBackground |
Sets the background color of this object. |
void |
setBounds |
Sets the bounds of this object in the form of a Rectangle object. |
void |
setCursor |
Sets the cursor of this object. |
void |
setEnabled |
Sets the enabled state of the object. |
void |
setFont |
Sets the font of this object. |
void |
setForeground |
Sets the foreground color of this object. |
void |
setLocation |
Sets the location of the object relative to the parent. |
void |
setSize |
Resizes this object so that it has width and height. |
void |
setVisible |
Sets the visible state of the object. |
