hi, in my Frame i want to detect that the mouse has been moved over a button. ( i am programming in java ) how can this be acheived ? i have an object 'a'( say a frame ) and in it another object 'b' ( say a button ). now 'a' can be the actionlistener of 'b'. is it possible that 'b' can be its own actionlistener ? 'b' is a button. - chetu
