QML__Nokia

QML是一种描述性的脚本语言，文件格式以.qml结尾。语法格式非常像CSS(参考后文具体例子)，但又支持javascr ipt形式的编程控制。我个人认为它结合了QtDesigner UI和Qtscr ipt的优点。QtDesigner可以设计出.ui界面文件,但是不支持和Qt原生C++代码的交互。Qtscr ipt可以和Qt原生代码进行交互，但是有一个缺点，如果要在脚本中创建一个继承于QObject的图形对象非常不方便，只能在Qt代码中创建图形对象，然后从Qtscr ipt中进行访问。而QML可以在脚本里创建图形对象，并且支持各种图形特效，以及状态机等，同时又能跟Qt写的C++代码进行方便的交互，使用起来非常方便。

-QML__Nokia QML is a descr iptive scr ipting language, at the end of the file format. Qml. The syntax format very much like the CSS (refer to later specific examples), but support javascr ipt form of programming control. Personally, I think it combines the advantages of QtDesigner UI and Qtscr ipt. The the QtDesigner can design ui interface file, but does not support the interactions and Qt the native C++ code. Qtscr ipt can interact and Qt native code, but there is a drawback, very inconvenient if you want to create a scr ipt inherited from QObject graphic objects, graphic objects can only be created in Qt code, then be accessed from Qtscr ipt. QML can create graphics objects in the scr ipt, and supports a variety of graphical effects, as well as a state machine, and convenient interaction while written with Qt C++ code, it is very convenient to use.
