Hi @m_magalhaes

This was research for a feature I'll start implementing soon, and possible refactor.
I'll mark as solved and if there's anything else I need I'll open it again.

Thanks.

Nevermind. Trying to explain will probably lead us too far. I was only wondering if messaging was possible between a CommandData and its GeDialog.

Hi @C4DS, just to confirm that there is nothing built-in Cinema 4D.

For python most of the library in the end only reroutes through OS call and does have a system dependant call, so you will probably end with something like that also in C++.

Cheers,
Maxime.

@m_magalhaes said in GeUserArea - RemoveLastCursorInfo not compatible with ActivateFading:

ActivateFading is also using RemoveLastCursorInfo internally.

I more or less assumed this was the case.
As such I went with an alternative solution using RemoveLastCursorInfo to be able to detect the mouse leaving the GeUserArea, while providing an own implementation for fading in and out.

Thanks for confirming.

@PluginStudent
Yup ... it's official, I need glasses on top of my glasses.

Thanks for pointing it out.

@m_magalhaes
Thanks for the example. I am sure this will be helpful in future, however for now I am still stuck with the classic API to remain backwards compatible.

While there isn't a readily available solution to the problem, a few options have been mentioned how to handle this. As such I will set the topic as solved.

hi,

without further feedback i'll set this thread as solved tomorrow.

Cheer,
Manuel

Thanks! seems to work well!

the problem is that apparently it only runs on the tag, if I set the option as a UserData of my object, it doesn't work

Looking at the doc in R19:

So I'm afraid there is no simple solution that will work on each version maxon::String being introduced in R20, you will need to adapt your code.

Cheers,
Maxime.

Hi Pim sorry for the late reply, this is possible by using the lib_py.h (typically this is somehow what we used before R20 to expose feature in python, but it's way elder, not everything is possible to do, you have less control than with the new python.framework, and the lib_py.h is not maintained (so don't expect any enhancement in it) Only the python.framework will be enhanced.

// Init Python GePython pythonScope; pythonScope.Init(); // Acquiere the GIL GePythonGIL gil_state; pythonScope.SetNode("doc", doc); // If doc->GetFirstObject() is nullptr, op variable will not be declared in the python scope, and you cant add a None. pythonScope.SetNode("op", doc->GetFirstObject()); maxon::String pythonCode = "\ import c4d\n\ \n\ def main():\n\ print(doc, op)\n\ \n\ if __name__ == '__main__' :\n\ main()\n\ "_s; StopAllThreads(); pythonScope.Run(pythonCode);

Cheers,
Maxime.

Hi Manuel,

Thank you for giving me some time to check this out.
So after a bit of testing and changing the code to work with Cinema I cannot replicate the issue. As you mention it seems to be related to Pyblish.

I did find interesting that when running the code in Cinema without Pyblish you can't see the active frame running through the timeline, while you do see it when running through Pyblish. Perhaps that's the correlation with the crash.

I will close this as solve, for the fact that it does not crash in the Cinema context.

Thanks again!

Hi @Thodos in which version are you? And would it be possible for you to share a scene?

Thanks in advance,
Cheers,
Maxime.

hi,

thanks a lot for sharing your code 🙂

Don't forget to change the state of this thread to solved. (if it is)

cheers,
Manuel

Hi @pyr, I've just reached the development team about it.

So for them, this is not a bug since FieldList store only baseLink.
In Python, we don't have BaseLink, but if you are not aware of what it is, please read BaseLink Manual.

But since there is no BaseLink in Python, if a link points to a destructed object (like in your case, Python simply returns None)

So I guess your workaround is ok.
Cheers,
Maxime

@C4DS

That was the most normal happy smiling glad you solved your issue emoji I could find. Any of the others could definitely have been interpreted in many ways. Hope that one came across alright 🙂

Hi @C4DS , maybe I wasn't enough clear.

you end up with a single merged object, which has 2 selection tags, and both still have the specific name ... but none have the added unique ID. Surely you start to think something is really wrong.

Actually you end up in a new mesh with new selection tags which beside having the data copied from the two source selection tags, they are NEW and hence the UniqueID is not supposed to be kept. The names are kept for convenience but I don't see any reason to have also the UniqueID being kept considering that - in the end - they are indeed new instances and have nothing to do with the source selection tags.

Cheers, R

@m_magalhaes
Thanks for reminding me of the GeDialog::CoreMessage.
I totally overlooked that.

Well @pyxelrigger thanks for clarifying the final scope.

Since, as already stated, folding or unfolding a scene entry doesn't generate any valuable message to be intercepted, the sole - brute force - hack you might try to implement in Python would be to implement a MessageData plugin which constantly checks for the folded/unfolded state of the entries in the scene and eventually delete the unfolded one.

This approach carries strong performances penalties to the whole Cinema 4D UI because you need to constantly traverse the scene and depending on the scene size this could strongly affect Cinema performances.

If there are no further question please mark the thread as solved.

Best, R

There is no relationship between BaseContainer IDs and plugin IDs.

All you need is a unique ID, that you can use as a BaseContainer ID. This forum (the plugin ID page) provides such IDs.
