Eclipse SmartHome comes with a flexible infrastructure for handling icons that are to be used within user interfaces.
This bunde registers a servlet under the url
/icon/, which can then be easily queried for icons using GET requests of the form
categoryis one from the list of channel categories or any custom category that might be used within the solution -
state(optional) is the string-representation of an item state
format(optional) defines the requested format to be either PNG or SVG
iconset(optional) specifies an iconset to use
If no icon set is specified in the request, “classic” will be used as a default. This default setting can be configured by the setting:
Icon sets can either provide icons in PNG or SVG format or both. All standard channel categories should be covered by the icon set in the supported format.
Icon sets can easily be added as additional bundles. All that has to be done is to register a service, which implements the
IconProvider interface. Icons are provided as byte streams, so they do not have to be static resources, but can also be dynamically generated at runtime (e.g. for providing specific icons for certain states).
