java - How to keep the look of disabled JTabbedPane's tabs to look exactly like when they are active? -

i using jtabbedpane , set of tabs disabled. @ same time need keep tabs when active. don't need them grayed in colors. move between tabs using next , previous buttons. purpose of tabs visual indicator.

i tried this code answer. works, how modify correctly disabled tabs when active tabs.

i mean default look of swing active tab components:

by active tab mean enabled no matter whether selected or not.

i set of tabs disabled. @ same time need keep tabs when active. don't need them grayed in colors.

maybe can use jlayer or jtabbedpane#settabcomponentat(component).

(4) no other alternative known me use visual indicator.

how using jslider.
