A Screen is the basic object for interfacing with users. In it, they can insert the following objects:

•Primitives from a graphical editor (lines, circles, rectangles, polygons, etc.)

•ActiveX controls provided by Elipse Software (E3Alarm, E3Chart, E3Browser)

•ActiveX controls provided by a third-party

•Non-vector images (BMP, JPG, GIF files, etc.)

•Vector images (WMF, EMF files, etc.)

•Default Windows controls (List Box, Text Box, Combo Box, etc.)

•E3 graphical libraries (XControls) composed by any of the objects cited previously

•Viewer Folders, Queries, Counter, Demo, Internal, and Timer Tags

Screens use as a standard for size and coordinates called the Himetric units, given in 1/100 mm, not in pixels. In this system, when adding a positive value to x, the x coordinate moves to the right. When adding a positive value to y, the y coordinate moves down, and its origin is given by the top left corner of a Screen.

Screens can be opened in Full Screen mode, filling the whole E3 Viewer area, or else as modal screens, filling only the size of their height and width coordinates.
