Bob Schellink commented on CLK-545:
-----------------------------------
No worries, at the end of the day its just software :)
The latest checkin does in fact resolve #2. However with this change we don't
gain anything. We simply move from a <span> to an <a>. Plus we potentially
break existing styles. For example, I can imagine existing sites using the
following CSS to style disabled links:
span.disabled {
text-decoration: underline;
color: 808080;
cursor: pointer;
}
Using a span is also advantageous in that screen readers will ignore them. When
using <a>, I believe a screenreader will read these links. For a blind purpose
this serves no purpose.
I also noticed that links now has a CSS dependency. While this won't matter for
non-ajax apps it would affect the upcoming Ajax support. Reason being when a
Ajax request is made and a link should be returned it used to be quite simple:
request -> return -> <a href="">blah</a>
With a CSS dependency the Ajax request becomes more complex:
request -> return -> <link src="control.css"></link> <a href="">blah</a> ->
browser now has to make another request to the server to load "control.css"
Also the opacity setting doesn't work very well on text. If you look at a
disabled button for example, the text is still very clear and easy on the eye.
No squinting is required. That is why I was asking for pointers to the UI
guidelines because I find it strange that they would recommend opacity for text.
> Better rendering of disabled link controls

> Key: CLK-545
> URL: https://issues.apache.org/jira/browse/CLK-545
> Project: Click
> Issue Type: New Feature
> Components: core
> Reporter: Adrian A.
> Assignee: Adrian A.
> Fix For: 2.3.0
>
>
> Add better rendering of disabled link controls. Right now is a simple span
> text and there's no visual hint that this might be a disabled Link (except
> for that ActionButton).
> Possible improvements:
> - 50% opacity for images/icons
> - title on mouse over
> - href browser status bar hint on mouse over (but no click possible - since
> the link is disabled)
