Scrollbars
Scrollbars are used to change what you view in a subwindow. For instance, in a text subwin-
dow, scrollbars are used to scroll through a document. In a canvas subwindow, scrollbars can
be used to see another portion of the paint window (which can be larger than the canvas
subwindow). This chapter addresses specific functions of scrollbars themselves. These func-
tions are applicable to any XView package that has scrollbars attached. If you are interested
in how to utilize scrollbars for a particular package, you should consult the chapter that dis-
cusses that package.
OPEN LOOK describes scrollbars using the visual metaphor of an elevator riding on a cable,
which is attached at both ends to anchors. Figure 10-1 shows a scrollbar from the OPEN
LOOK
GUI Specification Guide.
