I created a swing window,but when the mouse is exited from thewindow then the border should vanish,but i dont know how to achievethis.Can any one help me in this issue.
for jcomponent its like this ... even u set the border to emptyborder the borderwill always appear. if u do componet.setBorder(null) then the border won't bedisplayed.This might be applicable for frames. i have'nt tried , if u try let me know.
I think whether a top Frame's border can be disabled is determined bythe native OS. As the Java GUI libs are designed for use in all the OS,this feature hasn't been implemented, AFAIK.
