Abstract: A configurable user interface arrangement representing data elements of a data source. The user interface arrangement includes a dynamic tree structure monitoring area displaying at least one tree structure having at least one node, each tree having a root node, each node representing a data element or a set of data elements, and each node being user selectable. The user interface arrangement also includes a configuration editor able to establish a configuration code set, the configuration code set defining the structure of the tree structure(s). Each node in the tree structure(s) defines a set of reading commands to be executed when a node is selected in the tree structure monitoring area. The user interface arrangement also has a content monitoring area for monitoring the content or a part of the content of a selected node, the content being established by the set of reading commands. A user may obtain information by selection of a node in a tree structure.
