Rob, can you please:
(a) test and (hopefully) confirm that this patch
fixes your issue too?
I tried this patch (thanks for the prompt work).
It helps, but isn't a fix...
When I click the counter, it now increments two
values (usually) and then stops. It doesn't skip from
2 to 4, I see the intermediate 3. It goes 2, 3, 4 and
then stops -- for a single click.
Occasionally (once out of 20+ attempts) it will
only increment by one (my sequence switched from even
In my demo I need to hold the mouse button for a
"significant" time. This time is presumably longer than 0.1
sec which is the repeat timer of Fl_Counter. This can be
seen clearly in the existing code: if the FL_RELEASE event
is delivered before the timer event the internal variable
`mouseobj` is reset and the timer repetition is terminated.
Is it possible that your mouse button "click" lasts longer
than 0.1 sec?
I am just clicking the mouse in a normal way. I am not
dwelling on the button in any way. I don't have a millisecond
stopwatch connected to my mouse finger -- but I'm not doing
anything unusual as a user.
Yes, I see this too now on macOS under certain conditions. I pushed
two commits that solve (AFAICT) all problems I could see on Linux
and Windows (the latter tested only shortly using Wine on Linux).
There was indeed an issue with the new timeout handling (thanks for
pointing this out) but there was also something going awry in the
Fl_Counter code. The two mentioned commits fix the obvious issues.
Please update your FLTK repo and try the latest commits with your
program and please try also my latest demo program which I posted to
GitHub issue #450 which you created.
The behavior on macOS is weird and I'd like to get feedback from
others testing my tiny demo program on their macOS systems.
Instructions can be found at
Thanks in advance for all feedback.
Is a counter supposed to repeat events if you hold down the
button? I guess I'm failing to see how it doesn't behave like
a normal button press and why we don't see this problem for
all kinds of FLTK events.
Yes, it is supposed to repeat if you keep the mouse button pressed:
once every 0.1 seconds after an initial delay of 0.5 seconds. This
is also true if you drag the mouse over the buttons (while keeping
the mouse button down, of course).
If it is 'supposed' to repeat, then I should probably avoid
Fl_Counter in the first place and just use normal buttons.
What did you want to achieve with the Fl_Counter in the first place?
Do you handle different buttons differently?
Anyway, clicking on one of the buttons in a "normal" way should
never trigger the auto-repeat function and this is what I don't
understand (yet) in the macOS implementation. This is really a
strange and unexpected behavior.
