A Screen is the basic object for an interface with users. The following objects can be inserted into it:
•Primitive shapes of a graphical editor, such as straight lines, circles, rectangles, or polygons, among others
•ActiveX controls supplied by Elipse Software, such as E3 Alarm, E3Chart, or E3Browser
•Third-party ActiveX controls
•Non-vector images, such as BMP, JPG, or GIF files
•Vector images, such as WMF or EMF files
•Standard Windows controls, such as List Box, Text Box, or Combo Box, among others
•Elipse Power graphical libraries (XControls) composed by any object described previously
•Viewer Folders, Queries, Counter, Demo, Internal, and Timer Tags
Screens use a Himetric standard for measuring size and coordinates, which is given in 1/100 mm, not in pixels. In this system, if a positive value is added to x, then x coordinate moves to the right. When adding a positive value to y, then y coordinate moves down, and its origin is given by the upper left corner of a Screen.
Screens can be opened in Full-Screen mode, occupying all Elipse Power Viewer's area, or as modal Screens, occupying only the size of their height and width coordinates.
