Method Detail

• findFirstShowingWindow

  private static Window findFirstShowingWindow(Window w)

  Search the containment hierarchy updwards for the first showing window.

• getAnyShowingWindow

  @CheckForNull
  private static Window getAnyShowingWindow(Window[] windows)

• getLastFocusedWindow

  @Nullable
  public static Window getLastFocusedWindow()

  Returns the last window which received the focus. If no window received the focus yet or is already made eligible for finalization, null is returned instead. Note that this is not the same as Windows.getCurrentKeyboardFocusManager().getFocusedWindow(): The latter may return null if no window in this JVM has the focus, while this method will return the last window in this JVM which had the focus (unless this is also the first call to this method).

• getParentWindow

  public static Window getParentWindow()

  Returns a suitable parent window, which is the last explicitly set and still showing parent window or any of its showing parent windows, the last focused and still showing window or any of its showing parent windows or any other showing window - whichever is found first. If no showing window is found, JOptionPane's root frame is returned.

• observeFocusedWindow

  private static void observeFocusedWindow()

  Ensures that the focused window managed by the current keyboard focus manager is observed.

• setLastFocusedWindow

  private static void setLastFocusedWindow(Window w)
