I just need a regular JButton that will differently respond if a user click at left or right half of the JButton. It will serve as "Back/Forward" buttons, but mixed into single JButton.
Not bad idea, but I already have my GUI layout with set of 4 JButtons in a column settled at the right-down corner of my frame. The second one should be "Select" button. I don't want two buttons instead of one "Select" button, because I want to have a label over only one button, like "< Select >" so the user can navigate selection to the left or right in my app.
