Seaside meaning ?
by Serge Stinckwich 16 Apr '04

16 Apr '04

Hi all, during a presentation of seaside i made for some friends, someone ask me about the meaning of Seaside name. I read something about aubergines on the seaside swiki, but i didn't get the pun ... maybe a private joke ? BTW, i have made a french presentation of Seaside and the pdf slides are available here : http://www.iutc3.unicaen.fr/serge/SergeStinckwich/2004-04#02 Cheers, -- Serge Stinckwich -< ) Université de Caen>CNRS UMR 6072>GREYC>MAD /~\ http://purl.org/net/SergeStinckwich (/ | Smalltalkers do: [:it | All with: Class, (And love: it)] _|_/

Naming URLs
by Samuel Tardieu 15 Apr '04

15 Apr '04

I have three questions for which I cannot find an easy answer: 1- How can I name an URL so that the user can bookmark it (it doesn't make use of the session and continuation ids here) or jump directly to it? If my base URL is /seaside/wsff, I want a /seaside/wsff/statistics to land where I want. 2- How can I get dynamic parameters ? I would like /seaside/wsff/lookup/aaa.bbb.ccc.ddd to display a page depending on aaa.bbb.ccc.ddd (which in this case is an IPv4 address which will be looked up in an external database). 3- Where can I find information about this and SeaSide techniques in general? Is there any Seaside wiki? Sam -- Samuel Tardieu -- sam(a)rfc1149.net -- http://www.rfc1149.net/sam

Seaside 2.5a on SqueakMap
by Avi Bryant 15 Apr '04

15 Apr '04

Hi all, I've just published the first alpha release of Seaside 2.5 on SqueakMap. Although it's not yet feature complete in every detail, I'm pretty sure that the really major changes have all been made, and the scope of the release is determined. The summary release notes are below. Over the next few days, I'll provide more detail for each of the changes. Please try it out over the next few weeks. After Smalltalk Solutions, I'll try to polish off the remaining features and get a beta out by late May. Changes from Seaside 2.3 to 2.5: * complete rewrite of Configuration framework - dynamic, programmatic specification of attributes and default values - multiple inheritance model allows site-specific defaults to be combined with app-specific defaults for individual deployments - will be able to save and load .ini files * subclassing WASession is deprecated - many of the responsibilities of the Session class have been distributed to other classes, to allow better composability and configurability: - WAMain (and subclasses) takes over the #start: method - WAErrorHandler (and subclasses) takes over exception management - WARenderLoop takes over the main event loop - individual components take over filtering * #children is required on components - each subclass of WAComponent must now implement the #children method to return a collection of its visible subcomponents. - this enables: - per-component filtering (transaction and authentication wrappers around specific parts of the page) - callbacks execute in a dynamic scope that matches the page structure (wrap exception handlers around your subcomponents' actions) - multipass rendering (not yet implemented - one pass for headers, one for HEAD, one for BODY, allows streamed responses) - each component can contribute independently to the bookmarkable URL * new Decoration model for components - a Decoration is a lightweight component (no call/answer) that can be transparently wrapped around other components - many features from 2.3 (delegation, filters, validation, #onAnswer:) are now just types of decoration - can be used to add generic headers, footers, borders, buttons, etc - can provide a complete alternate look for a component * direct in-browser manipulation - "Toggle Halos" on the browser will display borders with tool icons around every component and decoration - halos host tools for debugging and for collaboration (with designers, translators, etc): - can browse code, inspect objects, view HTML source for each component - in the future will provide CSS and localization editing * misc enhancements: - stream large static documents - access #request from HtmlRenderer - WADynamicVariable provides portable fluid bindings - fast ISO character encoding by default - thread safety fixes - last-resort status 500 error handler - simplify ProcessMonitor to perform better under load (no longer maintain 1 process/session) - use form/query params for session and continuation IDs instead of URL segments - good, CSS-friendly base classes for common types of forms - more conventional category names - build HTML on a stream by default, rather than constructing a DOM - use absolute redirects if server hostname has been configured - XHTML output Cheers, Avi

RE: [Seaside] Icons in Seaside app

Hi Germán, > I want to use icons instead of text links in a Seaside app, > may be the same > icons in use in the 3.7 image. > > Also wants to be able to show a "tooltip" (aka ballon-help) > when the mouse > is over the rendered icon. > > Does exist some example about it? I'm not sure about an example elsewhere, but here's what we did in an app here recently. Anything you put inside the second parameter to anchorWithAction:do: gets linked. You can show a Squeak Form object as an HTML image - something like html anchorWithAction: [self showCommentsPage] do: [html attributes: {#border -> 0}. html imageWithForm: self class commentsImage]. (commentsImage answers a Form with the comments icon.) The #border -> 0 avoids showing a link border around the icon on the page. Tooltips are also easy - just use the 'title' attribute of any element. html anchorWithAction: [self showCommentsPage] do: [html attributes: {#border -> 0. #title -> 'Show comments'}. html imageWithForm: self class commentsImage]. Hope this helps, Ben Schroeder

Icons in Seaside app
by Germ�n S. Arduino 14 Apr '04

14 Apr '04

Hi People: I want to use icons instead of text links in a Seaside app, may be the same icons in use in the 3.7 image. Also wants to be able to show a "tooltip" (aka ballon-help) when the mouse is over the rendered icon. Does exist some example about it? Regards. gsa.

Debug option still present in deployment mode?
by Samuel Tardieu 13 Apr '04

13 Apr '04

In Seaside 2.5-avi.77, setting deployment mode to true doesn't seem to prevent the "Debug" button from appearing when an error occurs. Is it the expected behaviour? Sam -- Samuel Tardieu -- sam(a)rfc1149.net -- http://www.rfc1149.net/sam

How do I call a method from renderContentOn:
by ld 13 Apr '04

13 Apr '04

I'm new to Seaside. It seems very powerful, if I could just understand it better. I have worked through the tutorial, and thought I'd practice by modifying the WACounter example to change the change 'interval' from the browser.. I added a 'interval' variable. Then added a selectFromList to 'renderContentOn:' to quickly change the interval that the counter is incremented/decremented by. renderContentOn: html html heading: count. html anchorWithAction: [self increment] text: '++'. html space. html anchorWithAction: [self decrement] text: '--'. html break. html horizontalRule. html text: 'Change the interval'. html paragraph. html form: [ html selectFromList: (1 to: 10) selected: interval callback: [:i | interval _ i]. html submitButton. ]. html text: 'how do I call the setInterval from here?'. ------- Next, factored the form into a setInterval method: setInterval: html html text: interval. html space. html space. html form: [ html selectFromList: (1 to: 10) selected: interval callback: [:i | interval _ i]. html submitButton. ] ------- My questions are: 1) Is my factoring correct? 2) How do I call this from 'renderContentOn:' ? Thanks for you patience with such simple questions. - Larry Kelly
