Behold, finally a big update to the RAP Developer's Guide! After neglecting it a bit in the last release, the RAP team worked hard to get it in shape for Juno. With a lof of the information on RAP scattered around in blogbosts, forum entries, wiki pages and javadocs, newcomer (and in some case experts) might have a hard time to puzzle out how this...
Read MoreThe RAP team started working on a new feature called ClientScripting. It's still in it's infancy and will not (yet) be part of the core framework , but its already very useable. The goal is to allow adding pieces of behavior to the client-components of RAP widgets. This makes it possible to have swift, dynamic user feedback in situations that require a certain amout of...
Read MoreIf you ever need a WYSIWYG editor in your RAP application, look no further. I originally implemented this as an example of how JavaScript applications can be embedded in RAP as custom widgets. So if you have a similar scenario, you could also use this project as a template. The editor is fairly customizable, read the README for details. You can get the code on GitHub. Update:...
Read MoreGood keyboard controls have become a staple of modern web applications, such as Google Mail, Github (press “?”) and Flickr. However, almost every browser implements key events slightly differently, all with some quirks, and none of them like in SWT. For this reason, key events in RAP had, until recently, several issues and limitations. That is a thing of the past now, as the key events implementation has been largely rewritten in RAP 1.5M5, and now finally works reliably. This also brings some general changes to RAP key event handling.
doit flag on key events.Consider this: I measured the time needed to create 200 Buttons in RAP 1.4 and RAP 1.5M3, and it shows a considerable performance boost (at least for the browsers i tested). One reason for this is that we changed from quirksmode to standard rendering in IE9, which among other things, finally allowes us to use its new HTML5-features (in this case SVG and CSS3). I expect...
Read MoreRAP already offers advanced styling features including customizable cross-browser gradients, rounded borders and animations. We now complete this feature set by introducing advanced, configurable shadows, giving your RAP application a modern, subtle 3D-look. Unlike other frameworks, RAP does not rely on pre-rendered images to create those effects. Instead it does all the rendering itself based on CSS declarations, using multiple browser-native technologies for drawing. Up until...
Read MoreYour early Christmas present from EclipseSource: a custom-widget that displays, controls and reacts to a Google-Map. While there have been similar widgets before, this one is the first (as far as I know) that runs in RAP and RCP without any changes. [ Download ] (You also need RAP 1.4M4.) Creating custom-widgets for RAP is no easy task. You need to be familiar not...
Read MoreIf you ever wondered if RAP runs on the iPad, the answer is now YES. We fixed a number of iPad-related bugs for 1.4M2, and now it runs (almost) trouble-free. You can even start your RAP-application in fullscreen, making it look more like a native app. See for yourself with this video: ...
Read MoreAnimations are an integral part of most modern UIs, including many "web 2.0"-applications and websites. (Just watch carefully when opening google.com.) They have become so common that we even subconsciously miss them if they aren't there. The transition between two states of an UI should never be sudden, but gradually (albeit quickly), as we are used from real life. If done right, this increases usability...
