[jira] Commented: (XAP-344) Should support a passthrough mechanism for setting up css classes on components

Turyn, Michael commented on XAP-344:
------------------------------------

Widget styling may depend on more than one html dom node's styling---for example, we might want a header to be grey with a solid black border, the content panel to be inset and  rgb(255,255,240), ahd the enclosing node (rootDomNode in our parlance) to have a ridged border.

I would suggest that <em>eventually</em> we go to a more complicated system that  will map to named nodes in the widget, so that we can apply (e.g.):
                myWidget-footerMouseOver
                myWidget-clientMouseOver
                myWidgetMouseOver
...where the last still applies to the enclosing dom node.

Eventually; for now let's don't over-complicate.

> Right now there is no good way to assign custom classes to widgets. I propose:
> 1. All xal elements should support the class attribute which is a space-separated list of classes. 
> 2. For each entry in the attribute we should assign that entry to the base HTML container node/ root dom node. (Simply pass through to the underlying HTML tag)
> 3. In addition we want to support the various style states. So if they have a class called myClass we should automatically adjust that to myClassMouseOver the same way we do for built-in classes. Currently we have logic in AbstractWidgetBridge that will automatically change the class attribute to different permuations of the tag name, like "buttonMouseOver", "buttonMouseDown", etc. We should allow user-defined classes to use the same process and automatically add/remove state-specific permutations with mouse events.
