WaveConnector for GWT: Local Testing and Turnkey Gadget Development

with 4 comments

[tweetmeme source=”jonashuckestein” only_single=false]Hello everybody, today I announce my first open source publication :D I’m excited so please leave comments and let me know what you think or if you run into problems :)

Introducing WaveConnector for GWT 0.0.1

WaveConnector allows you to develop Google Wave gadgets and to test them locally in hosted mode! Head over to the project site at Google Code for more info.

The turnkey archive that is provided on the project site has everything you need to get started! It already contains the little project I made for the tutorial last week, so you can just downloaded the waveconnector-gwt-turnkey archive and start from there. There is no need to download anything else. Hit the jump for a really short How-To that’ll get you going in no time.

And now… a screenshot of our WaveListGadgetGWT running inside a hosted mode browser!

Update: Apparently the old gwt-gadgets gadget linker for GWT does not support power features such as code splitting and resource bundles. This is not acceptable. I am currently looking into whether its possible to use the xs linker instead. In that case the communication with the gadget js api would have to be reimplemented (or maybe taken from gwt-gadgets).

Bummer.

A Wave Gadget + Robot using GWT 2.0 and Google App Engine, Part 1

with 8 comments

[tweetmeme source=”jonashuckestein” only_single=false]I finally got around to playing with Google Wave (wave me: captaincurk@googlewave.com) and decided to build my own extension. Things got somewhat complex, so I made this into a multi-part tutorial. We are going to develop a gadget for Google Wave (in case you don’t have an invite yet, drop me a line) using Google Web Toolkit and wire it up to a robot that lives on the App Engine cloud.

In this part, we are going to develop a simple collaborative gadget that lives on a wave. You should be familiar with Google Wave and have some experience in developing applications using Google Web Toolkit.

An Editable Label for GWT with UiBinder and EventHandlers

with one comment

I just learned how to make custom widgets EventHandler-aware so that you can add EventHandlers to them. It turned out to be a little tricky so I thought I’d share that :) To make it more interesting, I’ll also make use of UiBinder and develop a particularly useful widget. The EditableLabel widget. It consists of a label, that becomes editable when clicked and can have attached ValueChangeHandlers (which a Label usually doesn’t have). For this tutorial I used GWT 2.0.

Click here to see a demo of the EditableLabel widget.
