Hello @merkvilson, Thank you for reaching out to us. This topic is not Cinema 4D SDK related I therefore moved it. But I can't log in to my account on the plugin cafe forum. I tried to change the password but it changed only the current account password. I assume this means that the reason for not being able to login is that you lost your password. But I am not quite sure what you mean by "current account" password. While this forum cloned the user settings and data from the old forum (Plugin Café), they are still two separate forums. So, if you want to reset your Plugin Café account, you would have to do it on https://plugincafe.maxon.net/. There is no need to keep passwords of both forums 'in sync'. I have forcibly logged you out from Plugin Café and manually sent you a password reset e-mail. I also sent you five plugin IDs you can use via PM. Cheers, Ferdinand

@merkvilson said in GUI Bitmap Button Properties: @ferdinand said in GUI Bitmap Button Properties: How to change BITMAPBUTTON_BACKCOLOR via the Command? I am not sure if I am understanding your question here correctly. You want to change the background color of a button after CreateLayout ran? That is not possible. You can flush layout groups and rebuild them at runtime (with buttons with a new color for example). I showed here once the pattern of a dynamic dialog. Is it possible to change the background color based on the toggle state? Thanks for your answers! It depends on how you define 'possible'. Dialogs in itself are static GUIs, you cannot change any of the settings you have set in CreateLayout after the method ran. It does not matter if it is the spacing of a group, the width of a text field, or the background color of a bitmap toggle button. What you can do in addition to defining the 2nd icon of the toggle button, is flush a layout group and then rebuild that group with a button which has the color you like. So, you wrap all your buttons in a group, and whenever a button is toggled on or off, you change a color in an array of button colors and then flush the buttons and rebuild them using your array of colors to set the background colors (and you also have to reapply the states then). The posting I linked to in my previous example lines out the details of how to do such dynamic dialog GUIs. Cheers, Ferdinand

Thanks @i_mazlov , The msg[c4d.BFM_ACTION_VALUE] is all I want, Thanks for that. Cheers~ DunHou

Thank you @i_mazlov It works perfectly Best regards, Tomasz

Hi @ferdinand Apologies for the late response. RE: You should show me how you access that key. My bad. But it's on the previous thread you answered by manually selecting a keyframe and storign it in a variable. https://developers.maxon.net/forum/topic/15344/get-selected-keyframes/3 RE: I just showed you above how to operate with percentage values in Cinema 4D. My bad. I missed it. I was looking immediately at the declaration. keyA: c4d.CKey keyB: c4d.CKey which I only want one key to be declared. === In summary, the GetNext() and GetPred() solved the problem in getting the Neighboring Keys from a Selected Key.

ok. I know not your department, but thats nuts. Thanks!

Hey @Visualride-0, you seem to run into some form of memory leak. That you open that many files in a row on one Cinema 4D instance is of course not really intended. This could either be a l smaller leak in our API that simply manifests more or only at all when you load that many files. Generally, you could separate out the file iteration into an external script, a shell script or a vanilla Python script if you want, and then simply run c4dpy with your script per file or for batches of 10 or 100 files. Starting and shutting down c4dpy 8000 times in a row will of course take its toll in time, so one would be incentivized to bundle up more files to bring down that number of starts and shutdowns. I had a look at your code, and apart from your redundant document insertion, I do not see much wrong with it, as it is basically just the loop on fileList. Cinema 4D should have caught your mistake there and prevented you from opening the same file twice, but I have not tested it. for f in filesList: # This line will load #f into a BaseDocument, insert it into the opened files, and make it the # active document. Unlike for BaseDocument.LoadDocument, the following lines are therefore # redundant. c4d.documents.LoadFile(f) # doc = c4d.documents.GetActiveDocument() # c4d.documents.InsertBaseDocument(doc) # c4d.documents.SetActiveDocument(doc) c4d.documents.SaveDocument(c4d.documents.GetActiveDocument(), f, c4d.SAVEDOCUMENTFLAGS_0, c4d.FORMAT_C4DEXPORT) # This does what it should do, close the active document, and create a new one. But to be # ultra safe, you could also call c4d.documents.CloseAllDocuments(). c4d.documents.KillDocument(doc) What escapes mea bit too, is the purpose of what we are doing here, since we just overwrite files with itself. But I guess this is minimized code, so it is only meant to demonstrate the problem. For my own understanding, the files in fileList are all *.c4d files, right? Fixing your code as shown above will likely not fix the problem, it seems more likely to me that there is a memory leak somewhere. For an intermediate solution, you will probably have to do what I proposed above, split this into batches of Cinema 4D or c4dpy instances to flush your memory by shutting down Cinema 4D. But we would like to have a look at the problem. Could you provide a sample of the documents, something between 10 or 100 files, so that we can test it with your data? You can send me a cloud storage link via a PM on the forum or via a mail to sdk_support(at)maxon(dot)net. Mail attachments will not work here due to the 50MB limitation. We strive for Cinema 4D being memory leak free, and if there is a severe leak we are not aware of, we should fix it. But this might take time. Cheers, Ferdinand

Hey Maxime, thanks for the quick answer. Actually I thought, I had tried SetValue() with that ID. But either I did something wrong or I tried something else... anyway, thanks. Just checked: Yes, I did something wrong. I stupidly just passed a string instead of a maxon.String. With the latter it works, not that I doubted your proposal. Maybe would be good, if SetValue() could throw an error, if a wrong type gets passed instead of just doing nothing. Also thanks for the pointer to Dunhou's project, I was already aware. Nice project! And indeed I peeked into it regarding some Arnold peculiarities... Cheers, Andreas

Hey @bentraje, yes, we are aware that internal and private tags are something that plagues our documentation as they often have been abused by developers to skip documentation. But that is not so easy to fix. I for example did and still do not know the purpose NBIT_TLX_SELECT2 either. I was just experienced enough with the C4D API to poke in this place first. Physically fixing the docs, i.e., adding a blab here or there, is not the problem. The problem is to evaluate if the private tag in C++ (which then radiates into Python) is well founded or not, especially for ancient things like this. I would have to read a lot of code to make an assessment if this should be private or not, and even then would not be sure. And even an 'Expresses the selection state of f-curve keys. @markprivate' is problematic because for that I would have to be sure that it does not have a weird side effect. Cheers, Ferdinand

@ferdinand Thanks for your reply！

I tried using a timer to solve this problem, but I still want to know if there is a more direct way import c4d import threading from c4d.gui import GeUserArea, GeDialog GADGET_ID_GEUSERAREA = 10000 class DropArea(GeUserArea): def __init__(self): # Used to store all objects involved in the drag-and-drop operation self.currentDragObjects = [] # Flag to indicate whether a drag operation is in progress self.isDragging = False # Define a timer to delay the handling of the drag completion self.dragTimer = None def Message(self, msg, result): # Handle drag-and-drop messages if msg.GetId() == c4d.BFM_DRAGRECEIVE: # Check if the drag was lost or canceled if msg.GetInt32(c4d.BFM_DRAG_LOST) or msg.GetInt32(c4d.BFM_DRAG_ESC): self.isDragging = False return self.SetDragDestination(c4d.MOUSE_FORBIDDEN) # If the drag just started, clear the previous object list if not self.isDragging: self.currentDragObjects = [] # Initialize the storage list self.isDragging = True # Mark the beginning of the drag # Verify if it is a valid drop area if not self.CheckDropArea(msg, True, True): return self.SetDragDestination(c4d.MOUSE_FORBIDDEN) # Get the dragged file object dragInfo = self.GetDragObject(msg) if dragInfo is not None: dragObject = dragInfo['object'] # Check if the object already exists in the list to avoid duplicates if dragObject not in self.currentDragObjects: self.currentDragObjects.append(dragObject) # Reset the timer to delay the handling of drag completion if self.dragTimer is not None: self.dragTimer.cancel() # Set a short timer (e.g., 0.2 seconds) to determine if the drag operation is complete self.dragTimer = threading.Timer(0.2, self._finalize_drag) self.dragTimer.start() # Set the mouse cursor to a valid state return self.SetDragDestination(c4d.MOUSE_MOVE) # Call the base class Message() method to handle other messages return c4d.gui.GeUserArea.Message(self, msg, result) def _finalize_drag(self): # Delayed execution to ensure all dragged objects have been received self.isDragging = False if self.currentDragObjects: # Print all dropped files print(f"Dropped files: {self.currentDragObjects}") # Additional logic can be executed here, e.g., handling file paths or other content # Clear the object list for the next drag-and-drop operation self.currentDragObjects = [] # Redraw the user area (if UI update is needed) self.Redraw() class ExampleDialog(GeDialog): geUserArea = DropArea() def CreateLayout(self): self.SetTitle("Drag Area") if self.GroupBegin(0, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, cols=1, rows=0, title="", groupflags=0, initw=100, inith=100): self.GroupBorderSpace(8, 8, 8, 8) self.GroupSpace(2, 2) # Add the user area gadget self.AddUserArea(GADGET_ID_GEUSERAREA, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 200, 200) # Attach the user area to the gadget self.AttachUserArea(self.geUserArea, GADGET_ID_GEUSERAREA) self.GroupEnd() return True if __name__ == "__main__": global dlg dlg = ExampleDialog() dlg.Open(dlgtype=c4d.DLG_TYPE_ASYNC, defaultw=200, defaulth=200)

Thx Maxim, so I'll have to wait until the next version..

Hey @CJtheTiger, just as a clarification, it is obvious that you have put quite a bit of effort in your posting. So, that was not meant in the sense of "what a terrible posting". But especially for postings which contain a lot of detail, it is important to put the question at the very beginning so that it is clear what is the question. Regarding the axis behavior thing, I now understand how you mean that. The Interaction Tag (and Tooling) is not owned by the SDK group, so we would not be responsible for this case either, we only own all the "pure" Python stuff. What I thought was your request before, changing the general default value, had probably almost zero changes of being implemented. This request of yours sounds logical (I am not a big expert on the interaction tag) but given how niche that case is, and that it would require customization in tools just for that case, I do not see a high chance that this will ever be implemented either. But if you truly desire that feature, you should still submit the wish, because a lot of user requests for the same thing are something we cannot and will not ignore. Cheers, Ferdinand

Marvelous @Dunhou, thanks yet again!! Here's the final script in case someone else has use for it: from typing import Optional import c4d doc: c4d.documents.BaseDocument # The active document op: Optional[c4d.BaseObject] # The active object, None if unselected def main(): # Retrieves BaseTime of frame 5, 20 start = 0 end = 1 if c4d.CheckIsRunning(c4d.CHECKISRUNNING_ANIMATIONRUNNING) == True: c4d.CallCommand(12412) # Play Forwards # Loops through the frames for frame in range(start, end + 1): # Changes the time of the document doc.SetTime(c4d.BaseTime(frame, doc.GetFps())) # Updates timeline c4d.GeSyncMessage(c4d.EVMSG_TIMECHANGED) # Redraws the viewport and regenerate the cache object c4d.DrawViews(c4d.DRAWFLAGS_ONLY_ACTIVE_VIEW | c4d.DRAWFLAGS_NO_THREAD | c4d.DRAWFLAGS_STATICBREAK) # Pushes an update event to Cinema 4D c4d.EventAdd(c4d.EVENT_ANIMATE) if __name__ == '__main__': main()

@ferdinand Hello Ferdinand, Thank you very much first of all. yes, you're right, I worked extremely sloppily with the SMC method, of course I'll take the threading into account and also work with a Temp Document. Regarding the problem itself, I can only say that reinstalling CINEMA 4D solved our problem. Cheers

Hi @i_mazlov , Thank you for confirming my solution. Best regards, Tomasz

Oof, that's an unfortunate end for me but at least I have a clear explanation. Thanks @ferdinand

@ferdinand thank you for your welcoming words, for your help and edits. Since I am no trained developer I was simply copy and pasting my first lines of code including the RegisterCommand function from the maxon python example github and thought it would fit my application since I thought the description in the sdk seemedlike a match to me ["Command can be dragged into an icon bar and delivers its own dialogs instead of icons." (- maybe I got that wrong)]. Also scince I have little developing experience the term "smallnode" is nothing I can make sense of and an accurate description seems to be missing. Nevertheless I tried your suggestion and it works like a charm. Thanks a lot Marc
