Abstract :
An approach to specifying graphical layouts of arbitrary objects, based on a TEX-like notation, is described. The simplest scheme offers specifications similar to TEX´s box-and-glue metaphor. Size and position of boxes and glue can be specified by constraints. Advantages of this TEX-like formalism are its expressiveness, user-predictable layouts, and efficient implementation schemes for the underlying layout algorithms. This forms-oriented scheme is extended and generalized for specifying advanced graphical user interfaces (e.g. CLOS class browser)
