Usage

From source file:Main.java

/**
 * Requesting focus in a Window should always be done last, after repainting etc.

 * which should make it the last UI action to perform and make it more likely
 * that the focus request works./*from w w  w  .  j a v  a  2 s . co  m*/
 * <br>See also {@link #requestFocusSelectAll(JTextField)}.
