2.2 Window System
In window-system environments, input and outputs are realized in windows. A
Window
is a rectangular area
on the screen the borders of which run parallel to the borders of the screen.
All tasks performed in the Line Computer Software are carried out in windows. It is possible to display and work
with several windows on the screen simultaneously.
The various windows on the screen represent the different applications. The user can work on them alternately
One application, in turn, can open several windows on the screen.
Several applications can produce outputs in their windows concurrently, irrespective of which window is currently
the active one, i.e. being edited by the user.
Windows may overlap or cover each other, which, however, does not affect the programs that are run in these
windows.
2.2.1 Window Types
Desktop (root window)
The
Desktop
is the backdrop for all other windows and fills the entire screen. All other windows and icons
are arranged on the desktop.

Main Window (application window)
An application can open several windows, i.e. the
Main Window
and several
Subwindows.
If the user closes
the main window, all subwindows of the application are also closed and the application program is exited.
A main window can be subdivided as follows:
- Menu bar
- Display area with/without scroll bars
- Command area
- Editing area (not available in all main windows of the application programs)
- Arrow button (not available in all main windows of the application programs)
