Hi,
The attached VIs uses the event callback to tab through clusters (not
arrays). This is very nice way to do it, because the vi is very easy to
reuse.
There are a few 'buts':
1) When focus is given to a control by mouse clicking in it, the tabbing
order is not changed (pressing tab will continue where it left off before
the click).
2) The code is quick and dirty.
3) The VI doesn't work well when the main is running continuosly (hence the
900000 ms wait).
4) There might be issues when other event structures or event callbacks are
used.
1) can be resolved, by checking each control references to see if it has
focus. This might take some time with many controls, so I didn't build it
in. 2) can be resolved, by putting some time in it. Any
way, the dirty code
is hidden inside the subvi. The cluster itself is tabbed, but only when
tabbing is on.
Regards,
Wiebe.
