Multiple Window Strategies
The multiple window strategy evolved at Xerox Prc with the 8010 star system and the Samlltalk programming system. On a sufficiently large and high enough reolution screen windows permit the user the multiple views that make a task easier.
Individual Window design
Window components include
Windows can be
- Titles, this can be highlit to show the active window.
- Borders or frames
- Scroll bars. One imporvement one might hope for here is the addition
of place holders to enable a return to a previously visited part of the document.
- Opened, care should be taken with the placement and size of a window
when it is first opened.
- Moved forward or backward in the stack of visible windows
Multiple Window Design
Options for Multiple Windows
- Split displays
- Tiling, either space filling or not
- Stacks (usually with tabs on the edges)
Coordination of Multiple Tasks by Windows
- Synchronized scrolling, may be appropriate for some linked documents.
For example one window might display names and another data on the named persons
- Heirachical browsing, here one window shows a heirarchy and another the contents of the selected member of the heirarchy. The File manager in windows, OS/2 etc. is an example of this.
- Two dimensional browsing, detail maps would be an example. xdvi supports a neat version of this with a cross psitioned by the mouse that when the mouse is clicked become a magnifying glass.
- Direct Selection, causing a window to pop up.
- Dependent window opening. eg when browsing the source code of a program
the code for called functions might appear in a close by window.
