class InternalFrameFocusTraversalPolicy
- Direct Known Subclasses:

public abstract class InternalFrameFocusTraversalPolicy
extends FocusTraversalPolicy
A FocusTraversalPolicy which can optionally provide an algorithm for
determining a JInternalFrame's initial Component. The initial Component is
the first to receive focus when the JInternalFrame is first selected. By
default, this is the same as the JInternalFrame's default Component to
focus.

InternalFrameFocusTraversalPolicy
public InternalFrameFocusTraversalPolicy()
-
getInitialComponent
public Component getInitialComponent(JInternalFrame frame)
-
Returns the Component that should receive the focus when a
JInternalFrame is selected for the first time. Once the JInternalFrame
has been selected by a call to
setSelected(true)
, the
initial Component will not be used again. Instead, if the JInternalFrame
loses and subsequently regains selection, or is made invisible or
undisplayable and subsequently made visible and displayable, the
JInternalFrame's most recently focused Component will become the focus
owner. The default implementation of this method returns the
JInternalFrame's default Component to focus.
- Parameters:
frame
- the JInternalFrame whose initial Component is to be
returned
- Returns:
- the Component that should receive the focus when frame is
selected for the first time, or null if no suitable Component
can be found
