Before using a webobject it has to be included like this:
<Include SRC="{{LISTBOX_PATH}}listbox.html" />
where 'listbox.html' contains the declaration of the
<WebClass> listbox. Then we use it like this:
<WebObject Class="listbox" Name="list1" . . . />
It would be better if the framework knows itself about the
location of the standard webclasses and can include them
automatically when an instance of this webclass is used.
In such a case there would be no need for the first line
above.
In case that it is not a standard webclass (and the framework
does not know about its location), or the developer wants to
override a standard webclass, then it can tell to the framework
about the path of the webclass using one of the following ways:
1 - <IncludeWebClass ID="my_listbox" PATH="path/to/my_listbox/" />
This is similar to the <Include> above, but has a more
specific syntax and there is no need to use it for the
standard (registered) webclasses.
2 - <WebObject Class="my_listbox" Path="path/to/listbox/"
Name="list1" . . . />
In this case the location of the webclass is specified at
the declaration of the webobject (/path/to/listbox/my_listbox.html
is the file that will be used by the framework and it should
contain the definition of the 'my_listbox' <WebClass>).
3 - WebApp::use_webclass("my_listbox", "path/to/listbox/");
This should be called in init() or in onParse() and it is like
registering this webclass so that the framework knows how to
find it.
