Method Detail

calculateInnerArea

public static Rectangle calculateInnerArea(Container c,
                                           Rectangle r)

Stores the position and size of the inner painting area of the specified container in r and returns r. The position and size specify the bounds of the container, adjusted so as not to include the insets. This method is useful for classes that implement painting code. Copied from SwingUtilities which uses JComponent instead of Container :-(

Parameters:

c - the Container in question; if null, this method returns null

r - the Rectangle instance to be modified; may be null

Returns:

null if the Container is null; otherwise, returns the passed-in rectangle (if non-null) or a new rectangle specifying position and size information

calculateCenter

public static Point calculateCenter(Component comp,
                                    Point point)

Calculates the center of a Component.

Parameters:

comp - the component

point - if not null, this point is used as return value

Returns:

the center of the component
