This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I have JSplitPane with a JScrollPane on the top and a JPanel on the bottom. I'm using vertical split. When user tries to move the divider up and down a line (like the line in MS Paint) appears and it moves up and down respectively. This is very weird.
Just for testing, I tried horizontal split and this weird line didn't appear.
Does anyone have any idea on what might cause that line to appear while resizing the divider?
