This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
i wanna implement a JTree with drag and drop functionality! but i have a little problem about how to form a line, or something like it , when you drag a node from the tree as a purpose of setting up the tree more precisely!
i have got a picture to illustrate it!
thanks a lot!
