Original Steve's note: Drag of pane splitters should be able to be cancelled by the Esc key. Other common user applications support this. My comment: It seems JSplitPane doesn't implement that feature. I also checked some app on linux (mozilla mail clieant, xpdf) and they dont implemented that. However on windows e.g. explorer mail client does.
