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

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?
cheers sebastian

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.

hi there,
i was shifting around some selections and noticed that some modeling commands seem to have no effect.
MCOMMAND_SELECTALL
MCOMMAND_SELECTINVERSE
i realize i can use SelectAll on the BaseSelect. and i could surely build a loop, to invert the selection. but why are these commands there? they even return true, despite doing nothing.

this is my code and a demo file:

import c4d
doc: c4d.documents.BaseDocument
op: c4d.BaseObject

def main() -> c4d.BaseObject:
    obj = op[c4d.ID_USERDATA,1].GetClone()

    bs_points = obj.GetPointS()
    #bs_points.SelectAll( obj.GetPointCount()-1 ) # will select all points
    c4d.utils.SendModelingCommand( c4d.MCOMMAND_SELECTALL,     [ obj ], c4d.MODELINGCOMMANDMODE_POINTSELECTION, doc=doc) # not working
    c4d.utils.SendModelingCommand( c4d.MCOMMAND_SELECTSHRINK,  [ obj ], c4d.MODELINGCOMMANDMODE_POINTSELECTION, doc=doc)
    c4d.utils.SendModelingCommand( c4d.MCOMMAND_SELECTINVERSE, [ obj ], c4d.MODELINGCOMMANDMODE_POINTSELECTION, doc=doc) # not working
        
    bc = c4d.BaseContainer()
    bc[c4d.MDATA_CONVERTSELECTION_LEFT]     = 0 # 0 = points
    bc[c4d.MDATA_CONVERTSELECTION_RIGHT]    = 1 # 1 = edges
    bc[c4d.MDATA_CONVERTSELECTION_TOLERANT] = False # tolerant conversion
    res = c4d.utils.SendModelingCommand( c4d.MCOMMAND_CONVERTSELECTION, [ obj ], bc=bc, doc=doc)

    res = c4d.utils.SendModelingCommand( c4d.MCOMMAND_EDGE_TO_SPLINE, [ obj ], doc=doc)

    return obj

circumvented the problem by generating 3 thicken objects - one for each surface part (shell, start cap, end cap). then created selection tags and stitched everything together with a connector object.

hi there,

the thicken generator object is a super cool and powerful tool. i'd like to use it inside of a python generator object, to create some more complex geometry. for this i need some of the selection options of the thicken generator. but activating e.g. 'shell' selection from within the python generator will mess up the output geometry of the thicken object and not generate any polygon selection tag. see attached c4d file.

after converting the python generator you have access to the built hierarchy and the generated thicken generator. when you select it and then try to activate some selection options ther will be no selection tags created. so it looks like something in the thicken generator is broken/uncomplete, when it is created within a python generator object.
is there any way to make this work, or is this a special case/limitation?

def main() -> c4d.BaseObject:
    source_obj = c4d.BaseObject( 5170 )
    source_obj[c4d.PRIM_CYLINDER_CAPS] = False

    thicken = c4d.BaseObject( 1060179 )
    source_obj.InsertUnder( thicken )
    thicken[c4d.SOLIDIFYGENERATOR_SELECTION_POLYGON_BOUNDARY] = 1 # does not create tag, will mess up (delete) geo of the selected polys

    return thicken

hi ilia @i_mazlov,
thaks for the advice about threading and the dummy document and the fishy part.

I continued testing the last days and noticed that it seems to work, when i insert a clone of the fieldlayer.
