[Qt-qml] Standards?

Tue Jul 20 16:51:11 CEST 2010

Ok, I just read Alan's article, and it was very good. He touched on several 
things that I think needed to be mentioned.

If I were writing a book, here's how I'd lay it out.
1. Introduction to Qt (C++, signals, slots, properties)
2. Introduction to QGraphicsView (QGraphics* classes)
3. Introduction to QML
   "Hello World"
   Syntax (It is unlike any other, blending JS and delcarations)
   Conversion (QGraphicsItem -> Item, etc)
   ECMA Scripting (how QML elements are essentially defineClass calls (or 
resemble them))
4. QML Runtime & Scripting
   Evaluation of scripts (how when QML is evaluated) root.height/3 is not a 
static assignment!)
5. Stock QML Elements
6. Making new QML elements in QML
7. Data Everywhere
   SQL Storage
   Network storage
   Abstract Storage Using QNetworkAccessManager
8. Models
   Delegates
   Lists 
   Trees
9. Using Threads
10. QML and C++ Living together in perfect harmony
   Data exchange
   Exporting new classes to QML
   Using QML-defined classes in C++
   Abstracting UI from Code 
11. Larger QML codebases
   Using multiple files
   Components
12. Targeting various devices
   Using Anchors to layout intelligently
13. Additional Nokia QML Libraries
   WebView
   Movility (Video, etc)
14. Writing your own Libraries & Plugins

Well, throwing it out there as a web standard I think would raise some eyebrows, 
get the attention, and make it hugely successful. People have been crying for a 
open source flash replacement. Tools like gnash don't fix the problem, as they 
don't compile the binary. 

I think all that would be needed is a reference implementation that is a browser 
plugin on OSX, Windows and Linux. 

We've got a chicken and egg problem. But getting one will produce the other 
eventually. I think having it as a web standard would help get both the 
quickest.

I think QML is brilliant and I'm being an advocate of it myself.

But we, around the Qt area, are the only one really aware of what it is.
It needs to reach a wider audience, and a wider knowledge base, to become a 
serious candidate.

That's what I meant.
