Infrastructure
About Dialog is a custom Tapestry component based on dojo Dialog. It has a defined look & feel (dialog css class in layout.css)
...
- about.vm (velocity template)
- AboutContext (spring bean responsible to put variables in the template and generate the output)
- New Classpath velocity engine (used by the AboutContext to find about.vm in classpath)
- AboutBean (spring bean used as a variable in the velocity template that has access to the contained Tapestry Page) variable name: defaultAbout
- Generic bean (a spring bean defined in a potential plugin, also used as a variable template) variable name: about
Benefits
...
No static text displayed
...
if a different, more complicated AboutPage needs to be implemented, simply only the about.vm template and AboutBean has to be changed to get new wanted data (dinamically)
...
Plugin capabilities
...
- create plugin specific about.vm template that simply overwrites the original about.vm (overwrite the about.vm path in the sipxplugin.beans.xml spring configuration file - can be automatically picked up by the newly created velocity engine that reads resources from classpath)
- create a plugin specific About Bean (it is automatically added as a variable in the about.vm by the AboutContext) that should have properties to retrieve any dinamic data needed
- localization support (IPage object is available in the about.vm - can be retrieved from the default AboutBean
...
Look & Feel
...
Specific dialog look&fell kept in a css class (in layout.css - can be easily overwritten in a potential plugin)
