I generally use visual studio code or IntelliJ for coding.
In that, I see that the title bar is coloured. Not only in that but in many apps I have seen that. Now I wish to try it out for my own applications also. But I haven't found anything that can accomplish my work.
I generally want like this.
jframe.setTitleBarColor(...)
But the above type is not available. Is there any other technique that I can use to achieve that?
CodePudding user response:
I think it's not possible. Because the top-level JFrame
acquires the look & feel of the machine's operating system.
By the way this program will help you to change the frame appearance with the help of LAF (Look And Feel):
