Thankyou. It ran, but it was something in your code that led to the answer, and
this time it really IS the answer:
SC:Connect(-1,wx.wxEVT_SCROLL_THUMBTRACK,DoStuff) -- Where SC is a SpinCtrl.
That's it! Do this instead of SPINCTRL_UPDATED, and it works.
What's even more amazing is that this removes the need for the KILL_FOCUS
correction too, it totally restores SpinCtrl to the behaviour it used to have
with wxEVT_COMMAND_SPINCTRL_UPDATED in wxLua v2.54, it appears to be an exact
substitute.
It was your use of EVT_SCROLL_LINEUP (and DOWN) that led me there.
First, I tried my own SpinButton code, and that failed because SpinButton has
its own breakage! Fails to use SP_ARROW_KEYS. Never mind what the docs say, it
doesn't work, nor does the mouswheel which works by default with that style (in
SpinCtrl anyway). But I also read that some (not all) of the SpinButton events
are also used (on some platforms) by SpinCtrl. I hunted online for any worked
example of event handling in SpinButton beyond yours, because there is none in
the sample scripts! I found my answer on some list of events, but I had no idea
if it would work till I tried it.
At times I despair of documentation! For example wx.chm states that
EVT_SPINCTRL is handled. Well it isn't, if you write that you just get an
error, you have to write wxEVT_COMMAND_SPINCTRL_UPDATED if you want that to
work! This isn't an example of transparent clarity! Worse,
wx.wxEVT_SCROLL_THUMBTRACK isn't named at all in this context, and given what
its name IS, it's hardly surprising that most users would have no clue that it
will work. Which means we have NO idea if it will still work later if
(hopefully when) someone cleans this up! Or if someone breaks the inbuilt
scrollwheel link with SpinCtrl, as seems to be the case with SpinButton
already, if it ever had one.
I love wxLua, I really do, it's let me do more than any other system so far,
but at times like these I wonder if it isn't a cloud of nonsense between me and
the API that I'd do better to blow aside completely. The naming, linking, and
conventions of event handling seem especially loose and uncoordinated. This is
really a case where ONLY a solid body of worked examples will do, documentation
is NEVER enough. Only established practise is going to lock this down.
Whether anyone cares enough to trust any of my code as a partial basis for
worked examples is something I doubt, but I will hand it over if you want it.
I'm willing to spend some time reducing several things I've done to minimal
demonstration scripts, if the effort is not wasted. I'm not the most
knowledgebale, but I am persistent enough to come up with answers, and I think
wxLua maybe needs all the help it can get, there aren't a lot of people
around...
Ok, I ranted again, but I think I earned the right to a little excess, given
that this mail does include the kind of answer that we need, very small, very
effective, as it gives a signal every time an attempt is made with SpinCtrl,
instead of taking from us the right to decide what events matter.
