How do I change the tooltip look and feel to the system's?

Question

I have added the line to set look and feel to system. This is found to work because the scroll bars have changed.

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

But when I set a tooltip to my JTabbedPane's tab, it does not show the system's look and feel for tooltips. Why is this? Screenshots are below.

System's look and feel:

Java's look and feel(?):

I want to set my tooltip to look like the system's which is in the first screenshot. How do I do this?

Have you called `JFrame.setDefaultLookAndFeelDecorated(true);` before changing the LAF? — Eng.Fouad, Jul 08 '12 at 04:38

Much work without the complete effect:

for getting the background you need a custom implemenation of ToolTipUI: basically extend BasicToolTipUI and take over the painting
register the custom ui delegate with the UIManager so that it is used instead of the default
theoretically, you can achieve the rounded corners of the window (the one containing the tooltip) by using a shaped window (public api in jdk7, a half-official workaround available for jdk6), you would need a shaped window. Practically, there is no way (except extreme hacking) to make the ToolTipManager use that window
