Hi all... I started playing with/digging into TG widgets and forms, and a few things came to my mind that I felt I would share (not sure it's really interesting but...).
* first thing: an interesting feature of Zope is the ability to have multiple submits on the same form, with a naming scheme specifying the real action for the form, ie: <submit name="handlerMethodName:method" .... /> will use <current_controller>.handlerMethodName() as handler (ZPublisher takes care of this dispatch) (err... not sure I'm very clear... sorry) This is definitively something I'd like to have in a TG forms/widgets framework, and I thinks this could be easily implemented in TG (at least with a default() handler doing the dispatch, but there may be better options with cherryPy filters or whatever) * Next thing is about form layout: The TableForm strategy is a first angle, but it will only work for very simple forms[1]. What I was thinking of is a combination of RowLayouts and ColumnLayout (both being widgets and widgetContainers). A RowLayout could contain one widget by cell, a ColumnLayout could contain one widget by line : - simple row layout : +---------+---------+---------+ | widget1 | widget2 | widget3 | +---------+---------+---------+ - simple column layout : +---------+ | widget1 | +---------+ | widget2 | +---------+ | widget3 | +---------+ We could even make [Row|Column]Layouts accept many widget per cell, with RowLayout displaying them vertically and ColumnLayout horizontally: - multi row layout: +---------+---------+ | widget1 | widget3 | | widget2 | widget4 | | | widget5 | +---------+---------+ - multi column layout : +-------------------------+ | widget1 widget2 widget3 | +-------------------------+ | widget4 widget5 | +-------------------------+ Now RowLayout and ColumnLayout being widgets themselves, one can combine them to make more complex layouts: +-------------+------------------------+ | +---------+ | +--------------------+ | | | widget1 | | | widget4 | widget6 | | | +---------+ | | widget5 | | | | | widget2 | | +--------------------+ | | +---------+ | +--------------------+ | | | widget3 | | | widget 7 | | | +---------+ | +--------------------+ | +-------------+------------------------+ etc... Since I do not yet fully understand how TG widgets work, I don't know which implications it would have, but I guess this should be possible... Now is it a good idea is another question !-) [1] (TableForm...) and it needs to handle hidden input widgets anyway IMHO - I tried adding something like this yesterday, but I guess it was way too late for my poor brain to still perform correctly :( -- bruno desthuilliers développeur [EMAIL PROTECTED] http://www.modulix.com
