Class TipUtil

  • final class TipUtil
extends java.lang.Object
    Static utility methods for homemade tool tips.

    This is blatantly ripped off from RSyntaxTextArea's "FocusableTips" class of the same name, but isn't re-used to prevent a hard dependency on the RSTA library.

    Version:
    1.0

      Returns the color to use for hyperlink-style components in tool tips.
      private static boolean isDerivedColor​(java.awt.Color c)
      Returns whether a color is a Nimbus DerivedColor, which is troublesome in that it doesn't use its RGB values (uses HSB instead?) and so querying them is useless.

      static void tweakTipEditorPane​(javax.swing.JEditorPane textArea)
      Tweaks a JEditorPane so it can be used to render the content in a focusable pseudo-tool tip.
