Changing the Cursor
The WtCursor function lets you change or set the cursor. For instance, when a long file is read into memory, you can display a wait cursor. You can select from a large number of cursors listed in
Appendix C: Widget Toolbox Cursors.
A call to WtCursor has the following form:
status = WtCursor(function, widget [, index])
The
function parameter specifies the type of cursor:
default,
system,
wait, or
set. If
set is specified, then you must specify a cursor index from the list in
Appendix C: Widget Toolbox Cursors.
