Hello,
Single-pane chart refresh is available via RequestTimedRefresh.
It allows to refresh as often as every second.
It refreshes periodically. Refreshing "immediately" would inevitably
lead to infinite loop (refresh-execution-refresh-execution-.... repeated
thousands times per second) and locking up CPU (so called busy wait loop).
It was possible in the past (5 years ago or so) using RefreshAll and I
got dozens of "bug reports" when users simply created codes that
triggered such infinite refresh loop locking up all computer resources
and not being able to stop this. Since then RefreshAll also includes
protection against refreshing too often precisely to prevent users from
shooting themselves in the foot by writing incorrect code.
GUI should rather be created using Parameters window.
Best regards,
Tomasz Janeczko

Thank you Keith but this refresh must be afl invoked. I am thinking of
"mouse-click" because this invokes an immediate pane-only refresh, I
can think of no other function that does that. The idea is to be able
to keep refreshing the chart at, say, 10xSec during mouse input. This
would allow creating very nice interactive GUIs.
I think Keith's idea might work if we place the AlertIf() at the end
of the code....

Have you considered using Auto Hotkey. It can produce mouse clicks
and has some timing control and looping.
I have never used it myself. But I know others on this forum have.

Thank you for your reply Chris,
If we had an afl-controlled chart refresh we could create much more
"responsive" GUIs. This is a missing function in the gfx library.
Right now gfx functions, like dragging items, using a slider, dropping
down menus, adjusting params, etc. are all "hesitant" because they
have to wait for the next refresh to show the new graphics. I have too
many parameters and functions to use the AB Param window, its just too
big. RefreshAll() is too slow because it refreshes everything; I just
want to refresh the selected pane.
I am not sure the AlertIf() would work because it is probably sampled
at the next refresh and the delay would still be there. If it is easy
for you to create an .exe I am willing to try it.
I am not entirely sure how to solve this, perhaps i am just
programming it the wrong way... or wanting to do too much.
Thanks for the idea Chris,
herman
