The TUIT API supports the creation of windows, menus, and dialogs. An application can include all of this functionality with a single TUIT API function call. A document browser window such as that shown in Figure 2 would be created with this single function call. There are also interfaces for grouping annotations by type or attribute values and for hiding or showing these annotations groups. Annotated text can be displayed with color highlighting, or with different font styles.
Users can also create their own text annotations to be stored with documents.
The segmentation is preserved as document annotations. Configuration support TUIT is configurable at run time on a number of dimensions through a standard configuration format using TCL-style syntax.
