DefaultFocusStrategy

public DefaultFocusStrategy(DockController controller)

Method Detail

focusable

protected boolean focusable(java.awt.Component component)

Tells whether the non-focusable component in reality is focusable. This is true for example for any child of a JComboBox.

Parameters:

component - the component which seems to be not focusable, but in reality is focusable

Returns:

true if component should be treated as if it would be focusable

getFocusComponent

public java.awt.Component getFocusComponent(Dockable dockable,
                                            java.awt.Component mouseClicked)

Description copied from interface: FocusStrategy

Given a Dockable this method tells which Component should be focused.

Specified by:

getFocusComponent in interface FocusStrategy

Parameters:

dockable - some dockable which is about to get the focus

mouseClicked - the component which was touched by the mouse and which would get the focus normally. Can be null.

Returns:

the component to focus or null.

• null indicates that this strategy cannot decide what to do. In this case a default component will receive the focus.
• mouseClicked forces focus onto mouseClicked, even if that Component is not focusable.
• any other Component will receive focus if focusable, or focus will be transfered to the next focusable Component starting the search at the returned value.
