Defining your own Flow Objects

This creates a block with a solid border and inserts the text "Warning!" in the start of its contents:

     prototype Warning extends block
     {
         function layout(element)
         {
             this.style.borderStyle = solid;
             this.append(new Text("Warning!"));
             ProcessChildren(element, this);
         }
     }
 
     style warning
     {
         fontSize: 14pt;
         display: Warning
     }
