Question

I’m looking to implement a simple list with Drag n Drop to reorder the list. However, I may want to add more DnD features in my CMS in the future too.

I’ve come across 3 options in my searches

• Drag-and-Drop Library for Google-Web-Toolkit (GWT) – http://code.google.com/p/gwt-dnd/
• Repository for GwtQuery plugins – http://code.google.com/p/gwtquery-plugins/
• a GWT2.4 mechanism Drag and Drop in GWT 2.4

Since GWT has evolved over the years, and I’ve found lots of old articles covering the topic of implementing DnD, I was wondering what the current best way is of implementing DnD in GWT (2.5)

Answer 1

If you can use the ‘native’ support implemented in GWT i recommend stick with this.

Advantages:

• speed , no extra library requirements

Problems

• somewhat limited functionality (limited by HTML5 native features)
• browser support limited ( make sure you have Internet Explorer support– if you need)

I used gwt-dnd for a complex UI with lots of Floating windows/panels (similar to desktop environment).
I recommend it if you are constrained by HTML5 features or browser support.
