12. Design Issues in Windowing Systems /windows
Basic Window concepts
Window can be considered as a Virtual Device for interaction.
Interface Components - "Widgets"
- Close Box
- Title Bar
- Zoom Box
- Scroll Box
- Scroll Arrow
- Size Box
Tools for windows design for programmers are available in the programming toolbox for every system (MacOs, Windors). The programmer can simply select the kind of window for the application and does not have to worry about the formating of the windows.
(For example Prototype for the Mac, Visual Basic, ...)
Most windowing systems contain standard window types:
- Text windows - up - and - down scroll - rows
- Graphics windows - scrollable - objects - coordinates
- Panes - subpanes - toolboxes
- Dialogue windows - not resizable
- Alerts - no actions - only acknowledgement
Important to use standard windows
- Not too many functions
- Only the actions needed
- Careful with several windows
