[richfaces-issues] [JBoss JIRA] (RF-12011) Gradient configuration in ecss

Dupont Dupont commented on RF-12011:
------------------------------------
Please note if we want to use this feature in RF-11994 (to allow automatic xcss to ecss
migration for custom grandients), we'll need to allow skin parameters as classname of
gradients.
Sample xcss :
{code:xml}
<u:selector name="body .blocAuthentificationInterieure">
<u:style name="background-image">
<f:resource f:key="SampleGradient">
<f:attribute name="gradientHeight" value="100px"/>
<f:attribute name="height" value="150px"/>
<f:attribute name="gradientColor"
skin="blocConnexionInterieureBackgroundColor"/>
</f:resource>
</u:style>
<u:style name="background-repeat" value="repeat"/>
<u:style name="background-position" value="0 50%"/>
</u:selector>
{code}
Gradient configuration in ecss

Key: RF-12011
URL: https://issues.jboss.org/browse/RF-12011
Project: RichFaces
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Reporter: Dupont Dupont
For the moment, gradients are :
# configured in resource-mappings.properties (i.e.
https://github.com/richfaces/components/blob/develop/input/ui/src/main/re...)
{noformat}
org.richfaces.images\:autocompleteButtonGradient.png=org.richfaces.renderkit.html.images.AutocompleteGradient\
{topColorParam=headerGradientColor ,bottomColorParam=headerBackgroundColor}
{noformat}
# and then used in ecss files (i.e.
https://github.com/richfaces/components/blob/develop/input/ui/src/main/re...).
{noformat}
background-image:
"url(#{resource['org.richfaces.images:autocompleteButtonGradient.png']})";
{noformat}
A simpler solution could be allowing gradient configuration directly in the ecss file,
e.g.
{noformat}
background-image:"url(#{resource['org.richfaces.dynamic:org.richfaces.renderkit.html.images.AutocompleteGradient?topColorParam=headerGradientColor&bottomColorParam=headerBackgroundColor']})";
{noformat}
org.richfaces.dynamic being a special library name telling Richfaces to instantiate
AutocompleteGradient and configure it on the fly.
This would enable to get rid of resource-mappings.properties for simple use cases.
N.B. : a control must be implemented to control which classes can be dynamically
instantiated (i.e. only allow classes implementing Java2DUserResource).
