<class>

The <class> tag defines a new tag, which be used anywhere in the source file where a built-in tag such as <view> or <layout> can be used.

Defines a new XML tag name, that can be used in the remainder of the application source. An element whose name is this tag name will inherit the attributes and content of this definition.

For example,

<class name="mywindow" extends="window" layout="y" title="My Class">
  <text>my class</text>
</class>

defines a new tag named mywindow. This tag can be used anywhere that window is used.

<mywindow x="10">
  <button>Click</button>
</mywindow>

is equivalent to

<window layout="y" title="My Class">
  <text>my class</text>
  <button>Click</button>
</window>

Class definitions must precede view definitions that use the name of the class. An application can use a tag that is defined in a library, if the library is included before the point where the tag is used.
