Are there open source libraries for Java to make implementation of drag and drop easier?
I plan to make something like the one shown below:
The program is Alice, where you can drag some elements on the left and nest them to the right. It’s open source, but they did not use any libraries I think. I’m wondering if we anyone know of open source frameworks that work this way, or assist in doing complex drag and drops.
If you use Swing I recommend working with the AWT internal drag and drop system.
As Sun mentions on their guides:
For a deeper look at swing dnd you should try the Drag and Drop-Guide.
If you decide to use a different toolkit than Swing you could be successfull finding any good third party drag and drop libraries.
