    <p><a href="http://en.wikipedia.org/wiki/Model_view_controller" rel="nofollow noreferrer">MVC</a> was invented on Smalltalk and is arguably the original <a href="http://en.wikipedia.org/wiki/Inversion_of_control" rel="nofollow noreferrer">Inversion of Control</a> framework. While somewhat more lightweight than its java counterparts, it has the basic concepts of a model holding the data, a view rendering the data in response to events propogated from a controller.</p> <p>Less flippantly, Java is actually needs a lot of framework support to do a web application without excessive quantities of boilerplate code. Smalltalk supports programming idioms such as <a href="http://en.wikipedia.org/wiki/Continuations" rel="nofollow noreferrer">continuations</a>, which allow an author to pretend they are not really writing event driven code. <a href="http://en.wikipedia.org/wiki/Seaside_(software)" rel="nofollow noreferrer">Seaside</a> works like this, giving the benefits of IoC with a somewhat more flexible development paradigm.</p> <p>EDIT: MVC is a framework for UI's in Smalltalk (arguably it's not really a framework as such, but the class library has built in support for it). It has the inversion of control property in that the view and model respond to events dispatched by the controller - the don't call us, we'll call you property. Inversion of Control is a design pattern within frameworks that's used to reduce the need for extensive boilerplate in java applications. In some definitions of an application framework, Inversion of Control is the main property that is viewed as distinguishing a framework from a library.</p>

    1. CONigel: I was aware that MVC originated with Smalltalk. What confuses me about this is that and IoC framework like Castle contains an MVC framework (MonoRail) and an IoC framework (Windsor) which suggests that they are different?

    2. COLanguage issue: Delegates/Closures/Callbacks/EventHandling is so easy on a smalltalk platform, as to be unremarked upon. Because it's harder to achieve IoC on other platforms, and because it requires scaffolding (framework) code to implement well, and consistently, one might expect to see a requirement for such scaffolding code in Smalltalk. There isn't any such need. Because it's easy.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
