Re: Notes and thoughts on the GTK+ meeting at GUADEC

[Christian Hergert <chris dronelabs com>]

Hello,

One of the items I haven't seen discussed is input validation.  Web  
frameworks such as Rails and Django spent a great deal of time making  
these easy to work with and I think that it should be considered for  
gtk+ 3.0.

FWIW, I hacked up a crude idea[1] a few months ago.  If others are  
interested in this feature, and willing to give me API guidance, I'd  
be willing to spend the time to implement it.

As primary features, I think it should cover,

  * Integration with GtkBuilder to build validations at design time
  * Ability to chain a validation request on button activate in a  
dialog and suppress the event if validation fails
  * Validation split into reusable validators and reusable style  
modifiers
    - Range validator, Regex validator, etc
    - Style modifier, or with css we can add/remove classes based on  
validation result

Comments and suggestions appreciated,

-- Christian
