I'm not sure I understand you correctly, or more precisely,
understand concretely where you're lost at so I'll try to guess...
i'm sorry i believe i transmit my mess on the message.
So far I undestand widgets are a way to programatically create reusable view components, which at some point have some logic (but it's 100% view logic)
now widgets can have other widgets inside and that's where my problem is. Because I'm not sure if I have to make a widget and then put stuff in there (like wxwidgets/Swing/SWT,etc.) and build some kind of tree.
or do something like ASP/JSP tags where you have a "complex tag" that will eventually be process as text.
If you need a form with one of the default templates you can subclass
ListForm or TableForm:
but that's not the case with other widgets like the GridView where you create instances.
class MyForm(XXXForm):
fields = [
TextField("username"),
SingleSelectField("gender"),
....
] # This list can also be a WidgetsList if you prefer it's syntax
validator = MySchema() # Individual validators can also be attached
to each individal FormField widget
ok I though that was the Idea but then the examples extend from CoreWD not the XXXform class as I expected
To use it, you need to display it in a template and to receive it's
input (and validate it). Do:
myform = MyForm()
@validate(form=myform)
@error_handler(method_wich_displayed_the_form)
@expose()
def controllermethod(self, **kw):
# kw holds *valid* and coerced values.
.....
If you need more control over the layout, just subclass 'Form' and
give it a custom template (I'd advise you to copy-paste TableForm and
replace everything between <form> and </form>).
umm yes I think that's what I need here.
Use display_field_for, and error_for to access the fields and their errors:
class MyForm(form):
fields = ....
template = """
<form .... >
${display_field_for("username")} <br />
<span class="error" py:if="error_for('username')"
py:content="error_for('username')" />
.....
</form>
"""

ummm though that was outdated.

will take a look thanks
