Abstract: Direct-manipulation graphics editors are useful tools for a wide variety of domains such as technical drawing, computer-aided design, application building, and music composition. Constraints can be a powerful mechanism for specifying complex semantics declaratively in these domains. To date, few domain-specific graphics editors have provided constraintbased specification and manipulation facilities. Part of the reason is that graphical editors are hard enough to develop without implementing a... (Update)

...is based on this pattern [18] In particular, the ValueHolder object is a generic Active Value. The Cooldraw [7] Unidraw [23] and QOCA [11] constraint solvers all use Active Values to represent variables explicitly: the last two uses are mentioned in Design Patterns [8]...
.... ThingLab [5] Many other drawing programs have embedded constraint solvers over the years including Juno [31] Juno 2 [21] Unidraw [20], and Penguin [8] Unidraw and Penguin both leverage QOCA, a constraint solver that (like Cassowary) is able to maintain arbitrary linear...
