Thanks, that solved the issue. -Pim

@m_adam Thanks. Works as expected.

Hi, I'm sorry for the delay, but I can only confirm what you said. In C++ it's possible to call RegisterCommandPlugin but not in Python at runtime. So I guess the best approach is to have as you suggested a menu entry (a pre-registered c4d script or CommandData) that will then create a PopuDialog with a list of all scripts, and then it's up to you to execute them with the code @lasselauch provided. So here an example of how to implement it. import c4d import os def main(): # Gets all python script of a folder searchPath = r"%appdata%\Roaming\Maxon\Maxon Cinema 4D R21_115_XXXXXX\library\scripts" pythonFiles = [os.path.join(folder, f) for f in os.listdir(folder) if os.path.isfile(os.path.join(folder, f)) and f.endswith(".py")] # Build the menu for all the entries menu = c4d.BaseContainer() for pythonFileId, pythonFile in enumerate(pythonFiles): menuId = c4d.FIRST_POPUP_ID + pythonFileId filename = os.path.basename(pythonFile) menu.InsData(menuId, filename) # Example to also list regular command. # Uses POPUP_EXECUTECOMMANDS in ShowPopupDialog flag so if its a command its executed directly menu.InsData(c4d.Ocube, "CMD") # Display the PopupDialog result = c4d.gui.ShowPopupDialog(cd=None, bc=menu, x=c4d.MOUSEPOS, y=c4d.MOUSEPOS, flags=c4d.POPUP_EXECUTECOMMANDS | c4d.POPUP_BELOW | c4d.POPUP_CENTERHORIZ) # If result is bigger than FIRST_POPUP_ID it means user selected something if result >= c4d.FIRST_POPUP_ID: # Retrieves the selected python file scriptId = result - c4d.FIRST_POPUP_ID pythonFile = pythonFiles[scriptId] # Execute it and copy the global to it ( so doc, op are accessible as well) fl = open(pythonFile, 'rb') code = compile(fl.read(), pythonFile, 'exec') exec(code, globals()) # Execute main() if __name__=='__main__': main() ``` Cheers, Maxime.

@PluginStudent @s_bach Thank you for the response. Both works as expected. RE: don't know why you think you need two groups. Just for reference, I was thinking of this logic if self.mode == True: self.Group1_Layout() else: self.Group2_Layout() Anyhow, no further action required

@r_gigante Thanks, I used an inverse scale matrix wen calculating my gizmo points.

Hi @m_adam Thanks for the patience. Your suggestions and reminders works are greatly appreciated. I guess the confusion stems mainly on my part because I posted slightly two different codes. You were responding to my initial post but I was thinking with the code from the succeeding post(the one in the rar file). Totally my bad. Anyhow, here is the working code (using the initial post) which works as I expected: import c4d class ColorButton(object): def __init__(self): self.width = None self.height = None self.color = None self.color = None self.btn_id = None self.menu_list = None def create(self, dlg, w, h, color, btn_id): self.width = w self.height = h self.color = color self.btn_id = btn_id bmp_color = c4d.bitmaps.BaseBitmap() bmp_color.Init(w, h) for y in xrange(w): for x in xrange(h): bmp_color.SetPixel(x, y, color[0], color[1], color[2]) bcBitmapButton = c4d.BaseContainer() bcBitmapButton[c4d.BITMAPBUTTON_BUTTON] = True bmp_btn = dlg.AddCustomGui(self.btn_id, c4d.CUSTOMGUI_BITMAPBUTTON, "", c4d.BFH_CENTER | c4d.BFV_CENTER, w, h, bcBitmapButton) bmp_btn.SetImage(bmp_color, True) def create_menu(self): self.menu = c4d.BaseContainer() for menu_item in self.menu_list: counter = 0 IDM_MENU = c4d.FIRST_POPUP_ID + counter self.menu.InsData(IDM_MENU, menu_item) counter += 1 class MyDialog(c4d.gui.GeDialog): def __init__(self): self.btn_id_list = [] self.class_btn_id_dict = {} def CreateLayout(self): red_button = ColorButton() red_button.create(self, w=50,h=50,color=(255,0,0), btn_id=6000) red_button.menu_list = ['Menu1', 'Menu2', 'Menu3'] self.btn_id_list.append(red_button.btn_id) self.class_btn_id_dict[6000] = red_button blue_button = ColorButton() blue_button.create(self, w=50,h=50,color=(0,0,255), btn_id=7000) blue_button.menu_list = ['Menu4', 'Menu5', 'Menu6', 'Menu7'] self.btn_id_list.append(blue_button.btn_id) self.class_btn_id_dict[7000] = blue_button green_button = ColorButton() green_button.create(self, w=50,h=50,color=(0,255,0), btn_id=8000) green_button.menu_list = ['Menu8', 'Menu9'] self.btn_id_list.append(green_button.btn_id) self.class_btn_id_dict[8000] = green_button return True def IsPositionOnGadget(self, gadgetId, x, y): # Be sure that the windows is opened, # in our case since we call it in BFM_INTERACTSTART it's ok buttonData = self.GetItemDim(gadgetId) if not buttonData["x"] < x < buttonData["x"] + buttonData["w"]: return False if not buttonData["y"] < y < buttonData["y"] + buttonData["h"]: return False return True def function_to_determine_gadgetId_under_mouse_cursor(self, x, y): for gadgetId in self.btn_id_list: if self.IsPositionOnGadget(gadgetId, x, y): return gadgetId def Message(self, msg, result): if msg.GetId() == c4d.BFM_ADJUSTSIZE: self._x = msg[3] # Retrieve Y size of the GeDialog self._y = msg[4] # Retrieve Y size of the GeDialog # We are on the main thread here elif msg.GetId() == c4d.BFM_INTERACTSTART: c4d.StopAllThreads() state = c4d.BaseContainer() self.GetInputState(c4d.BFM_INPUT_MOUSE, c4d.BFM_INPUT_MOUSERIGHT, state) if state.GetInt32(c4d.BFM_INPUT_VALUE) == True: x = state.GetInt32(c4d.BFM_INPUT_X) y = state.GetInt32(c4d.BFM_INPUT_Y) g2l = self.Global2Local() x += g2l['x'] y += g2l['y'] gadgetId = self.function_to_determine_gadgetId_under_mouse_cursor(x=x,y=y) if gadgetId in self.btn_id_list: if self.IsPositionOnGadget(gadgetId=gadgetId, x=x, y=y): button_class = self.class_btn_id_dict[gadgetId] button_class.create_menu() l2s = self.Local2Screen() print str(x+l2s['x']) + " :: " + str(y+l2s['y']) self.KillEvents() res = c4d.gui.ShowPopupDialog(cd=self, bc=button_class.menu, x=x+l2s['x'], y=y+l2s['y']) return True return c4d.gui.GeDialog.Message(self, msg, result) if __name__ == "__main__": dlg = MyDialog() dlg.Open(dlgtype=c4d.DLG_TYPE_ASYNC, pluginid=20304050)

Hello, Some symbols are not exposed to public. There's no particular reason for that. There's no real place where all exposed symbols are. (and we agree it's could be nice) To know if a BaseObject is a camera (or something) you can use IsInstanceOf You can also send a message using the ID MSG_GETREALCAMERADATA : with an alembic generator you can use this code : camera = doc.GetActiveObject() if camera is None: return if camera.IsInstanceOf(c4d.Oalembicgenerator) == False: return # This example tries to get the internal camera from a generator. # Typically used with the Alembic Generator camera. data = {} data["res"] = None res = camera.Message(c4d.MSG_GETREALCAMERADATA, data) if res: camera = data["res"] print("Camera: " + camera.GetName()) For your next threads, please help us keeping things organised and clean. I know it's not your priority but it really simplify our work here. Q&A New Functionality. How to Post Questions especially the tagging part. I've marked this thread as a question so when you considered it as solved, please change the state Cheers, Manuel

I found a reply here. https://developers.maxon.net/forum/topic/11447/get-message-from-treeview-gui-dialog/2

I know this is quite an old topic, @m_magalhaes @Jmelon it would compile if you put c4d.h at the end of all other STL includes

@mp5gosu This sounds like the solution I was looking for Thanks a lot! Ps, yes im a noob...

Thank you. I will look into it and try it.

Thanks for the answer. And yes, you are fully correct. Things should not be done in DrawMsg()

Hi sean, thanks for reaching out us. The broken forward compatibility between R20 and R21 is reported on Changes in R21. With regard to backward binary compatibility, it has never been possible to run a plugin built against a more recent API and load on a previous Cinema 4D executable as reported on Portability and Compatibility. Best, R.

Yes your code could be optimized but we agree with you here this is not really the point, a R20 code is expected to have the same performance with R21 and here this is not the case. And @C4DS I agree using GeIsMainThread() == false I would say partially fix the issue (sometimes it works as R20, sometimes not) We keep investigating it. Cheers, Maxime.

@s_bach said in Plugin not found after switching layout: The ID used with GeDialog::Open() and RestoreLayout() is typically the plugin ID of the CommandData plugin. See e.g. activeobject.cpp Thanks. It had to be something so simple I kept missing when reviewing the code.

Thanks for the explanation. Works as expected.

@m_adam Hi Maxime, thank you for the quick reply and insight into this. I look forward to trying this.

Correct, and I would say a CommandData id.

@r_gigante Thanks for the response. Works as expected.

@m_magalhaes Thanks for the confirmation.
