RE: Extending Textfield Question

Hi Howard -
 
Yours suggestions of using inheritance for my own text field worked great.
However, I also wanted to the same behavior in Radio, PropertySelection,
Select, TextArea and Checkbox.  These components do not have a
beforeCloseTag method.  Therefore, I must copy their entire renderComponent
method into my subclass.  Unless there is another approach, I would like to
file and enhancement request for these components to have a beforeCloseTag
method added.

TextField is designed for this, fortunately (mostly to support ValidField).
 
You should be able to copy the TextField .jwc into your application and
modify it to point to your own class.  Add the class parameter as direction
"in" to a property named "styleClass".
 
Subclass TextField and override beforeCloseTag() to insert your styleClass
property.
 
By putting TextField into the application specification it will
automatically take effect for all the pages of your application.

Hi -
 
We would like to have our own textfield with an HTML 'class' parameter.
This class parameter would have a default to our pre-defined style.  Should
I inherit from Tapestry's TextField or use delegation?  If I use delegation,
how do I pass the informal parameters to the contained Tapestry TextField?
 
Thanks...
Dorothy
