A graphical region is a rectangular portion of the screen in which other objects can be drawn.
A graphical region can have both a background color and a border color. This means you can create a logical division on the screen by defining one or more graphical regions and displaying other objects in them. In its simplest use, a graphical region is a way of painting all or part of the screen, and of setting off the painted area by displaying a border of a different color.
The initial attributes of a graphical region are defined in a graphical region definition. You can change any of these attributes during runtime.
If you define a region with just the required specifications, such as:
region Store size 50 50 at position 100 100
in a windowed application, ESL compiles this region as:
enabled visible black graphical region Store size 50 50
at position 100 100
white foreground
priority is 0 parameter is ""
The parent defaults to the primary region.
