+ \class QxtHtmlTemplate QxtHtmlTemplate
+ \ingroup QxtWeb
+ \brief Basic Html Template Engine
+
+ open a file containing html code and php style variables.
+ use the square bracket operators to assign content for a variable
+
+ \code
+ QxtHtmlTemplate index;
+ if(!index.open)
+ return 404;
+ index["content"]="hello world";
+ echo()<<index.render();
+ \endcode
+ the realatet html code would look like:
+ \code
+ <html>
+ <head>
+ <title>Test Page</title>
+ </head>
+ <?=content?>
+ </html>
+ \endcode
+
+ funny storry: whe are using this class to make our documentation (eat your own dogfood, you know ;).
+ but when we where parsing exactly this file you read right now the first time, QxtHtmlTemplate got stuck in an infinite loop. guess why. becouse of that example above :D
+ So be warned: when you assign content to a variable that contains the variable name itself, render() will never return.
+
+

+/*!
+ \fn QxtHtmlTemplate::open(const QString& filename)
+ Returns true on sucess and false on failure.
+ note that it will also return false for an empty html file.
+
+ \fn QString QxtHtmlTemplate::render() const
+ Uses the variables you set and renders the opened file.
+ returns an empty string on failure.
+ Does NOT take care of not assigned variables, they will remain in the returned string
