Styling is handled differently in qooxdoo than it is in other frameworks we have discussed such as Dojo. Whereas Dojo uses CSS for styling, qooxdoo apples CSS styles directly to the DOM nodes to accomplish the task of rendering visuals, and doesn't require CSS instructions in the code.
To use qooxdoo, you will need to have Python installed on the computer you will be using. If you are using the Windows operating system, you can download and install ActivePython Community Edition, which is free for development use. The same page also has versions available for Mac, Linux, Solaris and HP-UX operating systems.
One thing that might put off some developers is the use of a command line interface for creating the applications using qooxdoo. For instance, to create an application named HTMLGoodies, we would use the following command:
C:qooxdoo-1.3-sdktoolbincreate-application.py --name=HTMLGoodies --out=C:It's not difficult, but in today's WYSIWYG world, many developers are used to visually developing applications, and using a command line interface is a different animal. That said, qooxdoo has such an extensive feature-set, and ships with a myriad of examples and demo code, so it's worth the extra hassle.
The Effects Demo page includes some very nice transitions for images, including:
- Fade & Blind
- Fade & Slide
