博士 === 國立中央大學 === 資訊工程研究所 === 92 === There are two major types of tools for the construction of graphical user interfaces. One is user interface builder and the other is graphic system. The trend of developing interface builder is presentation-oriented. The constraint system has been used extensively for the construction of graphical user interfaces. High-level UIMSs support a high-level dialog model specialized for human-computer interaction. A major problem common to high-level UIMSs is that they are dialog-oriented and thus hard to use. A high-level UIMS, AppComp, is constructed that adopts a presentation-oriented user interface development methodology. The presentation-oriented methodology lets interface developers do the relatively easy task of creating the user interface presentation first; the system then helps them on the hard task of dialog specification later on. An immediate benefit of this approach is its support for a highly visual development environment. AppComp is more visual than previous high-level UIMSs and interface builders. Constraints have been used extensively for the construction of graphical user interfaces. User interface constraints that are declarative are more favorable but require sophisticated constraint planning algorithms. Constraint planning algorithms proposed previously are getting more and more complicated as they were asked to handle more general requirements. We believe that the difficulty is mainly caused by the complicated data structure that is translated directly from the problem. By a transformation, we propose a simplified graph model for the problem and prove that the constraint planning problem can be reduced to finding feedback vertex sets on the simplified graph model. We also consider the general problem of handling non-uniform user interface constraints.
