GWT: TrafficMap – GWT & Leaflet Map Example

Here is a nice GWT and Leaflet map application I wrote to ease myself back into GWT again after not having written a line of GWT code since 2009. It is a classic map and list type site which displays some sample data I downloaded from the UK Highways Agency traffic RSS feed. Not content […]

GWT: gTraffic Usage

I have Google stats activated for some of my websites including gTraffic the UK traffic Google map mashup. The site ticks over with fairly low stats of about 20 people a day (I salute you fellow traffic junkies). Occasionally when there is a bank weekend or a public holiday the stats jump to some fairly […]

GWT: gTraffic Timeline

I occasionally have a look at my GWT traffic mashup to make sure it’s still working. I was looking at it again tonight and was struck by how many good ideas it seems to have. Good ideas that no one else seems to have bothered to pick up on. As an example take a look […]

GWT: Flex integration

Well done to Christian Voigt for putting GWT and Flex together in a way that works. He has written a small library and demo plus a clear explanation on his blog page for those interested here. I have had a look at his solution and it makes mine look horribly over-engineered which I guess it […]

Flex: GWT: Developer Experience – Part 1

Introduction This is the start of a three part article focusing on my experience of using GWT and then Adobe Flex to implement versions of my UK traffic information site gTraffic. You can compare the two by looking at the GWT version and the Flex version. As an inital primer I will talk about the […]

Learning Flex

I have implemented the majority of the edit grid functionality for gwt-yui-ext. I have a hit a snag though and keep meaning to get back to it. For now, I have been working my way through Adobe Flex 2: Training from the Source. I’m about a quarter of the way through so far and reckon […]

Project Updates #1

After getting gwt-jsviz out the door I feel it’s time to take stock of my current list of on-going projects. gwt-jsviz The gwt-jsvix API wrapper was something that I had been putting some time into on and off for quite a while so I am glad to have the first revision up and running. Already […]

gwt-yui-ext update #2

I have made an important update to the gwt-yui-ext library. The grid control wasn’t much use if you couldn’t click on it and select items for editing etc so I have implemented the GridEventManager and GridEventListener classes. These will let you listen for clicks, double clicks etc and response by defining your own functions sub-classed […]

Roadworks and VMS

I am still trying to get the Roadworks and VMS (Variable Message Signs) feeds working again but I am having problems getting the authentication to work properly (I have username and password access to secured data). Please bear with me for the moment. Currently the data displayed for these map layers is woefully out of […]

GWT Flex Bridge

A recent thread on the GWT forum got me interested in the possibility of interfacing GWT to Adobe Flex. Adobe have released a javascript to flex ‘bridge’ component called FABridge. I have put together a (very) quick and dirty demo the two components talking to each other through the FABridge. This is far from finished […]
