Hartelt, Helga I.M.Magalhaes, Leo PiniDaltrini, Beatriz Mascia2015-10-052015-10-0519871017-4645https://doi.org/10.2312/egtp.19871006This paper presents a Window Management System, GAV, which utilizes a GKS Graphics System as a supporting tool. GAV allows the definition, by the users (designers of application programs), of several areas of visualization in the same screen. Each of these areas is a workstation according to the concept of workstation established in GKS. GAV even allows different parts of application programs to be done by different users. These users can use the full set of GKS functions in each part, without worrying about the existence of the other parts, Finally, GAV allows the grouping of workstation in sets called screen configurations. Advantages and disadvantages of the adopted solution to the problem of constructing a Window Management System are discussed.
