• getScreenBounds

  public static Rectangle getScreenBounds(Point point, boolean accountForInsets)

  Get maximum bounds for the screen that contains a given point.

  Parameters:

  point - Coordinates of point.

  accountForInsets - Deduct the space taken up by menu and status bars, etc. (after point is found to be inside bonds)

  Returns:

  Rectangle of bounds or null if point not inside of any screen.

• getScreenBounds

  public static Rectangle getScreenBounds(Component component, boolean accountForInsets)

  Get maximum bounds for the screen that contains a given component.

  Parameters:

  component - An AWT component located on the desired screen. If null is provided, the default screen is used.

  accountForInsets - Deduct the space taken up by menu and status bars, etc.

  Returns:

  Rectangle of bounds.

• fix

  public static void fix(Scrollbar sb)

• showCompositeAdvisory

  public static boolean showCompositeAdvisory(ImagePlus imp, String title)

• scale

  public static void scale(Component component)

  Scales an AWT component according to Prefs.getGuiScale().

  Parameters:

  component - the AWT component to be scaled. If a container, scaling is applied to all its child components

• scalePopupMenu

  public static void scalePopupMenu(PopupMenu popup)

• scale

  public static boolean scale(JComponent component)

  Tries to detect if a Swing component is unscaled and scales it it according to

  invalid reference

  #getGuiScale()

  .

  This is mainly relevant to linux: Swing components scale automatically on most platforms, specially since Java 8. However there are still exceptions to this on linux: e.g., In Ubuntu, Swing components do scale, but only under the GTK Linvalid input: '&F'. (On the other hand AWT components do not scale at all on hiDPI screens on linux).

  This method tries to avoid exaggerated font sizes by detecting if a component has been already scaled by the UIManager, applying only

  invalid reference

  #getGuiScale()

  to the component's font if not.

  Parameters:

  component - the component to be scaled

  Returns:

  true, if component's font was resized

• fixScrollbar

  public static final void fixScrollbar(Scrollbar sb)

  Works around an OpenJDK bug on Windows that causes the scrollbar thumb color and background color to be almost identical.

• newNonBlockingDialog

  public static GenericDialog newNonBlockingDialog(String title)

  Returns a new NonBlockingGenericDialog with the given title, except when Java is running in headless mode, in which case a GenericDialog is be returned.

• newNonBlockingDialog

  public static GenericDialog newNonBlockingDialog(String title, ImagePlus imp)

  Returns a new NonBlockingGenericDialog with the given title if Prefs.nonBlockingFilterDialogs is 'true' and 'imp' is displayed, otherwise returns a GenericDialog.

  Parameters:

  title - Dialog title

  imp - The image associated with this dialog
