Watch Cursor Revisited
Jan Eugenides
Waterbury Center, VT
David Stoops’ Animated Cursors from the December issue was interesting, but it
had two deficiencies:
1) It was hard-coded for eight cursors, instead of obtaining the real number of
cursors from the ‘acur’ resource,
2) It used SetUpA5 and RestoreA5, which should no longer be used.
I recoded the example in MPW C 3.0b1, with the modifications, and here is the
result. I also changed to an ‘acur’ resource with an ID of 128, so as not to conflict
with any system resources. The Rez source code for the watch ‘acur’ and the associated
cursors are as follows:
/* 1 */
#include
#include
#include

typedef struct {
short numCurs; /*number of cursor “frames” */
short whichCur; /*used as “frame” counter*/
