Subject [jira] Commented: (CLK-545) Better rendering of disabled link controls
Date Mon, 24 May 2010 09:42:24 GMT


Bob Schellink commented on CLK-545:

>This is the standard way of doing "disabling" of controls if I recall well. 

What standard is that and what UI guidelines are we talking about here? The only standards
I'm aware of is HTML4 and CSS2.1.

> IMHO it's the duty of the business logic or security filter to not allow the execution
of that link if the user doesn't have the credentials.

Just like that? So existing users who thought the link was obscured now has to implement new
logic? This sounds alot like self interest and not taking the greater Click community into

> Well, we do the exact opposite :). We are letting the user to see what he would get if
he would have the credentials :)

Well maybe your users are interested in viewing links in the status bar but I'm fairly certain
the majority of users are not.

To be honest I can't see this issue making it into Click core. This is such a core change
that affects every link rendered by Click and there are many conflicting points of interest
here. Security being a major one.

> 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)
