Im trying to update myJSplitPane` components directly after I drag the divider. I enabled instant updating of the components when I drag the divider. 
My problem is that the components getting resized a bit later than I drag the divider; that looks a littlebit confusing.

You can see the JScrollPane outside the window. 
I want to avoid that problem.
I tried: - Property change listener - Thread with 60fps
Nothing helps.
//SOLVED
Added a BorderLayout to my Panel and set the setPreferredSize as I need it.
