New type of Drag & Drop for GridLayout

Olivier Vanlekeren

Hello everybody,

I use Vaadin for a school project and I needed a GridLayout that carry out drag and drop. It exists the good DargDropLayout add-on, however it manages drop event only on empty cells. As the demo show it http://apps-johndevs.rhcloud.com/dragdroplayouts/#!dd-grid-layout    . So I developed my own little system in the purpose of swapping two components of the layout. See next to the '4' on the picture :-). What do you think about that? Would it be possible to to include my code to the DragDropLayout add-on for improving him? 

Thanks for your anwsers.

Hi,

I suggest making a pull request to the add-on's GitHub repo.

Yes, a repo request should be a good idea... I'm really impressed of what you are doing with your kids. Where you are teaching this? Can i send my children to your school?

Hello Matthias, I was a student and it was my final work of studies. Now I will be a teacher, so you are not completly wrong ^_^ . I posted my code to the repo, unfornatly there is a system that checks the code before to accept it and I did not understand its working. :-( I mailed the developer of the add-on but he did not answer me . If somebody is interested, I can share my code
