Just updated the string markup documentation page based upon the Gtk 2.24 developer docs. There's a lot more information here now. Other tasks worked on over the past couple of days is adding functionality to the gnocl::list object so that it will output its full content as a single Tcl list. This will simplify script development where the current method is to parse through each row and column to obtain specific values. The new code will also attach header and datatypes to the list. I envisage some complications where a list may have an embedded object such as an image. In such instances, the path to the image will have to be returned.
