Re: Magritte description to html input - smallwiki

9 Jun 2005

...
  How can we get a HTML component from a Magritte
description?
 We want to do a "general search". A type (DocumentItem) can be  
 selected, then the available descriptions are shown. Now if a  
 description is selected, we need an input field corresponding to  
 the type of the description to specifiy the search criteria.  
 (checkbox for boolean description, ...). We tried attribute  
 asComponent, attribute class defaultComponentClass, but neither  
 worked. 
I don't properly understand what you are trying to do. What is  
'attribute'?

...
  We can not use asComponentOn:  as we don't have a
specific object  
 to edit. 
Magritte requires a model to store the date when you want to show a  
dialog built from a description.

Probably the easiest thing you can do is to instantiate the selected  
DocumentItem and display a dialog on this one.

Other possibilities might be:

- you could use a scaffolder that contains a dictionary with  
associations of the form: description -> value. This is a technique  
that is commonly used for user defined forms. Take care, MAScaffolder  
in Magritte is currently not working, you should probably create your  
own class.

- you could write a Memento (older versions of Magritte called it  
Wrapper) that doesn't require a model.
