Adds the specified focus listener to receive focus events from this
component.
|
boolean |
contains(Point p)
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(Point p)
Returns the Accessible child, if one exists, contained at the local
coordinate Point.
|

getFont()
Gets the Font of this object.
|
FontMetrics |
getFontMetrics(Font f)
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.
