Exception(KTextTemplate::Error errorCode, const QString &what)

Detailed Description

The Exception class can be used when implementing AbstractNodeFactory::getNode. An exception can be thrown to indicate that the syntax of a particular tag is invalid.

For example, the following template markup should throw an error because the include tag should have exactly one argument:

 <div>
   {% include %}
 </div>

The corresponding implementation of IncludeNodeFactory::getNode is

 QStringList tagContents = smartSplit( tagContent );

 if ( tagContents.size() != 2 )
   throw KTextTemplate::Exception( TagSyntaxError,
     "Error: Include tag takes exactly one argument" );

 // The item at index 0 in the list is the tag name, "include"
 QString includeName = tagContents.at( 1 );
