Tag plugin - adding childs to Cycle

I have a Tag plugin and its properties are defined by a res file.
In it is a cycle field for which I want to add dynamically children.
Because it is not a dialog, I can not useGeDialog.AddChild
(id, subid, child)What should I do to add a child dynamically to the cycle?
LONG SWITCHFRAMESCYCLE { CYCLE { FRAME01; FRAME02; FRAME03; FRAME04; } }

Hi Pim,
in GetDDescription() you need to store/modify a BaseContainer stored under DESC_CYCLE, see Description.
In our C++ docs we also have a manual about Description Settings (here section Values).

Hi Andreas,
Great thanks you.
I think Descriptions are easier in c++ than in python. -

Hi Pim,
I'm not sure why Descriptions should be easier in C++ than in Python?
Since R18 you can pretty much work with them like in C++. But please, correct me, if I overlooked anything or misunderstood the comment. -

To be honest, perhaps it is my lack of understanding of python R16 Descriptions.
All these various levels, confuses me.
In c++, for me it is more straight forward.And of course, my main platform for developing plugins is still R16.
Maybe it is time to go over to R18.Could you perhaps do the c++ example in python for me?

So I have this tag plugin that uses this res file:
CONTAINER globalswitch { NAME globalswitch; GROUP SWITCHFRAMESGROUP { LONG STARTFRAME {MIN 0; } LONG nw1 { CYCLE { nw3; nw4; } } } }
What Descriptions should I use to add / remove child's from the cycle?

Hi Pim,
yes indeed, if you want to work with Descriptions in Python it will be much easier from R18 on.
Actually I'm not sure you will be able to dynamically fill a Cycle/Combo box in Python with versions previous R18, as you are lacking the ability to overwrite GetDDescription(). the only real option I see is to do it via Cycle in User Data. See this thread: Adding cycles to a UserData FieldFor everybody working with R18 and later, it's quite easy and roughly looks like this:
def GetDDescription(self, node, description, flags) : # Before adding dynamic parameters, load the parameters from the description resource if not description.LoadDescription(node.GetType()) : return False # Get description single ID singleID = description.GetSingleDescID() myCycleID = c4d.DescID(nw1) # using ID from above post if singleID is None or myCycleID.IsPartOf(singleID)[0]: # Add dynamic parameter bcCycle = c4d.GetCustomDataTypeDefault(c4d.DTYPE_LONG) bcCycle.SetInt32(c4d.DESC_CUSTOMGUI, c4d.CUSTOMGUI_CYCLE) bcCycle.SetString(c4d.DESC_NAME, "Cycle") # Cycle elements get filled into another container items = c4d.BaseContainer() items.SetString(0, "Item 0") items.SetString(1, "Item 1") items.SetString(2, "Item 2") bcCycle.SetContainer(c4d.DESC_CYCLE, items) # Add cycle to the parameters in specified group if not description.SetParameter(myCycleID, bcCycle, c4d.DescLevel(SWITCHFRAMEGROUP)) # group ID from above post return False # ... # After parameters have been loaded and added successfully, return True and DESCFLAGS_DESC_LOADED with the input flags return (True, flags | c4d.DESCFLAGS_DESC_LOADED)

Regarding creation from user data even if I think pgroof already understand it, but since there is no proper exemple for handle it, I would share a class I did for a plugin in order to help future readers.

Thanks, the cycle is now updated and indeed quite easy, thanks!
One questions:
I see that function GetDDescription is executed quite often.
So, I guess inserting the Cycle must be done somewhere else. For example in Init()?-Pim
PS one small error. The line "if not description.SetParameter(myCycleID, bcCycle, c4d.DescLevel(SWITCHFRAMESGROUP)) :" should have a DescID and not a DescLevel.

Look at the Message function and more specially about c4d.MSG_MENUPREPARE -

Is that the only way to detect whether a different entry cycle is selected, or is there a message I can check.

Hello,
GetDDescription() is called every time Cinema is interested in the parameter description of an element. The edited Description it not stored anywhere so you have to define your custom parameter description every time GetDDescription() is called (since the parameter description can change at any time).
If you are interested when a parameter value changed you can implement NodeData.SetDParameter() or you can listen for the MSG_DESCRIPTION_POSTSETPARAMETER message.

So, now I can update the children in the Cycle field.
In the tag plugin, message() is used to get the value to define a new child of Cycle.
I add the input to a List, that is used in GetDDescription to define the children of Cycle.However, how can I trigger GetDDescription to be executed, so the update Cycle is shown?
def Message(self, node, type, data) : if type == c4d.MSG_DESCRIPTION_COMMAND: if (data['id'][0].id == ADDCHILD) : data = node.GetDataInstance() child= data[CHILDINPUT] self.children.append[child] #used in GetDDescription to define the children of Cycle #now trigger GetDDescription to show the updated Cycle return True

Hello,
you can make the host object dirty be setting the dirty flag DIRTYFLAGS_DESCRIPTION. That should trigger GetDDescription () again.

Thanks, it works if I set the tag to dirty using DIRTYFLAGS_DESCRIPTION.
