      • createBlankImage

        public static Image createBlankImage​(int width,
                                     int height)
        Creates a white AWT Image image of the specified size.

        Lightens overly dark scrollbar background on Windows 8.

      • showCompositeAdvisory

                                            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 #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 L&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 #getGuiScale() to the component's font if not.

        Parameters:
        component - the component to be scaled
        Returns:
        true, if component's font was resized
