This is the easiest and shortest tip so far. If you want to do any of the following things:

  • learn how to use CSS
  • make your custom controls look like the standard controls
  • reuse an SVG path graphic used by a standard control (e.g. scrollbar arrows)
  • figure out how to navigate the structure of the standard controls
  • determine the color used for a specific item
  • consistently modify several standard controls

then simply take a look at the default CSS stylesheet that ships with JavaFX. The file is called modena.css and can be found in the jfxrt.jar file in this location: com/sun/javafx/scene/control/skin/modena/
