ah got it, thanks for the quick explanation!
so without super i would call SetFloat in an endless loop, because it returns itself.

hi there,

i have a command plugin that is dependent on the state of the active document. so i want to track if the document has changed.

there seems to be no dedicated core message. so i tried the following. but it gives me "basedocument is not alive", which makes senes in a way. but how can i make it work?

class MyDialog( ... 
   doc_old = None
   ...

   def CoreMessage(self, cid, msg):
        doc = c4d.documents.GetActiveDocument()
        if cid == c4d.EVMSG_CHANGE:
            if doc != self.doc_old:
                print ("doc changed")
                self.doc_old = doc

thanks,
sebastian

hi there,
i've built a python generator, where i use its cache unless some parameters are dirty. when close and reopen the scene, the cache is gone and has to be rebuild. in principal, is there (not too complicated) way to keep/save these caches inside the scene?
would this be possible with a python generator or a proper plugin?
i'm using python.

to be a bit more specific: by clicking a checkbox on the python generator, i do a cloth simulation in a temp doc. the result of the sim is convertet to polygons and returned by the python generator. the simulation is not super heavy, but it woud be nice if i could avoid the recalculation. so i'd like to store the point data in the scene/generator. i'd like to avoid external files too, if possible.

my code is a bit long at the moment, i would post a shorter version, if you say it should be possible ...
best, sebastian

@ferdinand said in SAVEDOCUMENTFLAGS_AUTOSAVE still added to the recent file list?:

But please provide instructions on how to use your code when required in the future.

oh shit, i'm so sorry. you're right. completly missed this one.
...
and of cause thanks for the explaination / clarification.

hi there,
i recreated the autosave functionality (and tweeked the post-fix a bit) to be able to trigger it on demand.
then i noticed the saved files still show up in the recent file list, even though i added the SAVEDOCUMENTFLAGS_AUTOSAVE flag. the documentation says this should not happen. adding SAVEDOCUMENTFLAGS_DONTADDTORECENTLIST makes it work.
is this correct or a bug or something else wrong with my code?

hi, thanks for the info.
i just updated to 2025.2.0 ... but i suppose the fix is not in this one yet? not sure when the release date was ...

Thanks for the preliminary feedback.
I'll wait patiently

hi there,
i'm working on a command plugin with gedialog, that i want to dock in the layout.
one of the gui elements is AddCustomGui c4d.CUSTOMGUI_FILENAME.
the paths that are stored can be quite long.
the problem is, that the dialog wants to show the complete string, which makes the dialog extremely wide.
this only happens when the dialog is docked. then i can not scale the dialog smaller then the length of the string/filename.
if the dialog is not docked i can scale it smaller and the overflowing string is hidden.
sadly AddCustomGui has no properties initw and inith. i tried some combinations of flags but had no success.
am i missing something?

i could place the element in a scrollgroup, but then the "open document" button might be hidden in the part that is scrolled away.
any other options or workarouds?

cheers, sebastian

oh well ... tried option B) as planned.
a python tag tracks the dirty status of some objects and starts a c4d.SpecialEventAdd(). this is received as a core message in my dialog. but when i go looking for the dirty objects, they are not dirty anymore.
my workaround for now is, to have a str userdata on the pyhon tag. once the tag detects a dirty object, it writes its name into the str userdata. my dialog can then read the name of the object and find it. feels quite cumbersome but works for now.

would there be a better/more hidden way to store the data?

hi there,

i have a bunch of objects with userdata. then i have a GeDialog plugin with mostly the identical userdata. the dialog plugin is intended to control the objects from one common panel. but there might be cases, where the objects are adjusted direktly, so the dialog needs to be updated. i'm looking for a solution for this case.

A)
am i correct, the change of DIRTYFLAGS_DATA can not be tracked from GeDialog directly via the message system? i could only track things, that trigger a global event?
i suppose it could be done with a timer, that checks the doc/objects every few millyseconds, but that feels very unprecise.

B)
with a python tag i can easily track the dirty status of objects, but from what i've read here, i can not send data (list of dirty objects) direkcly to the dialog/command plugin. i can just call my dialog and make it aware to look and find the dirty objects.

C)
there also seems to be c4d.GePluginMessage() and PluginMessage(). but i never found a clear statement, which plugin types are supported. i never even got c4d.GePluginMessage() to return True, which made me doubt myself a bit.

so i would try to go with option B).
any objections or completly different suggestions?

hi @i_mazlov,
ok, good to know.
i also tried to insert the thicken generator into a temp_doc, activating the selections and executing passes. but that didn't work either.

@i_mazlov Thanks!
makes sens. seems i only used the forgiving commands until now.

the code is run in a python generator. so by returning the object, it will be inserted into the scene.
