[e4-dev] CSS image loading

[Kevin McGuire <Kevin_McGuire@xxxxxxxxxx>]

I'm working on adding the ability to
load resources (images) in CSS.  I'm posting this here because it
affects the properties config for the modelled UI based apps and thought
folks might want to know about the changes.

Previously, resource lookup only worked
for java apps but not in the OSGi context.  To support it, I'm following
the pattern we established for specifying the style sheet location, but
in this case, you specify a path to the resources directory. 

For example, in the photo demo you'd
add to the plugin.xml:

         <property
         
     name="applicationCSSResources"
         
     value="platform:/plugin/org.eclipse.e4.demo.e4photo/images/">
         </property>

directory like:

style sheet like:
Tree {
        font:
Verdana 8px;
        color:
#666666;
        background:
url(bluefade-full.gif);        
       
}

and result:

I'm not sure if this is the best approach
though since:
1) it gives only a single location for
all images
2) appends the file name to the end,
which maybe isn't cool
3) requires the path have a '/' at end
(but maybe we could add one for free if missing).
