Re: [Pharo-project] A pattern for GUI programming (Morphic, Cuis, etc)

by StÃ©phane Ducasse

Juan I was looking a bit at triggerEvent: and I seein pharo and probably in squeak code like the following one mouseUp: anEvent "Change the cursor back to normal if necessary and change the color back to normal." self canResizeColumn ifFalse: [^ self]. (self bounds containsPoint: anEvent cursorPoint) ifFalse: [anEvent hand showTemporaryCursor: nil]. self class fastSplitterResize ifTrue: [self updateFromEvent: anEvent]. traceMorph ifNotNil: [traceMorph delete. traceMorph := nil]. self adoptPaneColor: self paneColor. self triggerEvent: #mouseUp So how does it fit your model?

The style for GUI programming is based on PluggableViews in MVC and PluggableMorphs in Morphic. The main idea is to have a reusable set of standard widgets that can be customized when used. There is a strict separation between views and models. Models don't know about views, they are never aware of them. Views know about their model and update it directly. Therefore views don't trigger events. > > This description is not only conceptual, or theoretic. The rules described here are to actually be followed. > > GUIs are built by composing widgets.

There could be at any time any number of different views active on the same model. They could belong to different technologies or frameworks. They could even be remote and run on a different computer. There could be no view at all. For example, the model could be driven by scripts or reside on a server and receive external commands.

Besides, a model should be able to run without any GUI at all. So any logic that belongs in the model but is included in the GUI will eventually be missing.

They can query Model Inquiries when needed. They can also issue User Commands when appropriate. Models are usually subclasses of ActiveModel. Let's consider a small example. We are building a GUI to operate on some Person objects. We'll consider an EntryField for the birthday of aPerson.

If for performance reasons the updating of subviews must be splitted in parts, then the views and subviews must be restructured accordingly.

The model is updated using the action and the optative actionAdaptor. Methods that react to user activity should update the model by just using the action, a simple message.

Gary what do you think about the main point of juan that View do not raise event to communicate to their models. I like that.

[Pharo-project] Pharo XMLRPC Project

by Sudhakar Krishnamachari

Is there anything that is complete with respect to the XMLRPC Project..? Our notes: vibhu and I have put through the package ported from the available squeak work: http://skrishnamachari.wordpress.com/2010/09/19/pharo-xmlrpc-kick-start/ This is just the first shot at it.. Will come up with the ConfigurationOfXMLRPC shortly to bind the dependencies properly and fix anything that may required to take care of it as possible. -skrish

Re: [Pharo-project] Looking for a C parser

by alexandre＠bergel.eu

Arg, I will check CAnalyzer. Parsing C is difficult. We use srcML to tranform C code into xml files, way easier to load.
