Introducing a Lightweight UI Toolkit: Bringing Desktop Development into Java ME
Please, feel free to open weather.res file in your Resource Editor and play with different combinations of colors, fonts, and images. Maybe some of you wonder why I have included all the images inside the resource file instead of downloading them (the RSS feed has some image URLs). Basically, I did this for two reasons: to show you how to include images, and secondly, some mobile operators control how much bandwidth is used by customers, and I wanted to consume the minimum possible.
You have learned the basics of LWUIT: using containers and forms and placing components on them following a layout. You also started to empower your application with themes, fonts, and images. In the next article, I will show you some advanced concepts, such as Lists, dialogs, tabs, and animations.
