碩士 === 國立中央大學 === 資訊工程研究所 === 87 === Our graphical objects are built as windowless ActiveX controls. ActiveX control is base on COM (Component Object Modeling), and a windowless control is a non-rectangle, transparent, fast, light-weight ActiveX controls. We use Aggregation and our methodology, Simulated Inheritance, to achieve object reuse and to support Automation, Dynamic Binding, and Dynamic Invocation. These controls fall into two major type : Output objects : These are primitive graphics like Line, Ellipse, Rectangle, etc. Input objects : These objects handle interaction and feedback to users’ inputs. All these controls can be used successfully and easily in our UIMS (User Interface Management System)-AppComp, and users can apply these controls and other windows widgets to build their application or customized graphical editors.
