如何将JFrame带到它后面的窗口后面？

Question

I want to make a JFrame with the drawn shadow. I made a undecorated window and made a background with shadow(grey) and empty part(green),and it can be dragged.

The problem is,when I try to drag the shadow or the empty part,the frame can also be dragged! I want to bring the window under the window(Another application) that was under it,just like I click on the window.

I tried setBack(),but it just put it under every window,not the back one.

How to click through the window?

I am unable to understand your question clearly. In case want a frame within a frame, then opt for JInternalFrame class.
