UserData issues

Take a look at the C++ docs here[URL-REMOVED]. DESC_CYCLE must be a BaseContainer that maps the ID of
each item to its name in the UI.

Now I just need to know how to change the name of the UserData tab from "UserData" to something else.

To make your own tab show up without showing the default "UserData" tab. You have to create a new group and place it below the default built-in group.

It should look like this in the UD manager:

|_ UserData (default)
|_MY_GROUP #The tab that shows up in the AM
|_Data #Your UD gizmo
|_etc.....

I know how to that by hand, in the UD manager.
I just don't know how to do it in commands, inside my ObjectPlugin.

I hate to say this to you Rui. Because I know how many times you've hit dead ends and started over using a different method to get around SDK limitations.
But I'm pretty sure that this is not possible to do with code.

It has to do with a long standing pet peeve of mine...Crippled TreeGUIs.
The UD gizmo is a TreeGUI gizmo. And whenever Maxon uses a treeGUI for something. They never fully expose all of it's options. So we hit a brick wall when trying to access it with code.
The OM and the timeline are the only exceptions I know of where the treeGUI is fully exposed to us.

You guys have to complain about this to Maxon. Or it will never change.

I will, Scott. Thank you for giving me that information.

So, it is not possible to change the name of the UserData tab.
And is that also true about being possible to group userdata gizmos in multi-colums?

1.) AFAIK there's no way to change the name of the UserData tab.
2.) AFAIK there's no way to have multiple columns

The columns you see in certain UD gizmos like the Latitude/Longitude option are laid out in the gizmo's CustomDataType code. And not by the UD manager.

The UD manager itself is fairly weak. Which is baffling to me. Because UserData is one of the most heavily used features in C4D.
I was stunned that I had to write my own UD sort function for them.
We get a lot more control using descriptions in .res files for laying out our gizmos. But descriptions have problems too. Like not being able to delete them, and not being supported in Python.
So either way you turn. You will hit a wall.

It is so strange that we have attributes like DESC_COLUMNS but we can't use it for anything.
Also, we have DTYPE_GROUP but we can't set any groups.

I love using .res files but I can't change their content dynamically. For example, I can create a LONG field set to CYCLE go create a dropdown list. But I have to set the content of the CYCLE inside the .res file and I can't change it using code.
This is quite limiting

We can make UD groups.
That one is possible.

Example:

#This example adds a UD group that has a child group of it's own  
  
import c4d  
def main() :  
  
  obj = doc.GetActiveObject()   
  if not obj: return False  
    
  #The top most parent group  
  rootGroup = c4d.GetCustomDatatypeDefault(c4d.DTYPE_GROUP)  
  rootGroup[c4d.DESC_NAME] = "Root"  
  rootGroup[c4d.DESC_TITLEBAR] = False  
  rootGroup[c4d.DESC_LAYOUTGROUP] = True  
  rootGroup[c4d.DESC_COLUMNS] = 3  
  obj.AddUserData(rootGroup)  
  
  #A group that's a child of the root group  
  childGroup = c4d.GetCustomDatatypeDefault(c4d.DTYPE_GROUP)  
  childGroup[c4d.DESC_NAME] = "childGroup"  
  childGroup[c4d.DESC_TITLEBAR] = True  
  childGroup[c4d.DESC_DEFAULT] = True   #The Default Open option  
  childGroup[c4d.DESC_PARENTGROUP] = obj.GetUserDataContainer()[0][0]  
  obj.AddUserData(childGroup)  
  
   
  #A string type UD entry for this group  
  childGrp_Item1 = c4d.GetCustomDatatypeDefault(c4d.DTYPE_STRING)  
  childGrp_Item1[c4d.DESC_NAME] = "Item1"  
  childGrp_Item1[c4d.DESC_PARENTGROUP] = obj.GetUserDataContainer()[1][0]  
  obj[obj.AddUserData(childGrp_Item1)] ="Hello World"  
  
  
  #A Real type UD entry for this group  
  childGrp_Item2 = c4d.GetCustomDatatypeDefault(c4d.DTYPE_REAL)  
  childGrp_Item2[c4d.DESC_NAME] = "Item2"  
  childGrp_Item2[c4d.DESC_PARENTGROUP] = obj.GetUserDataContainer()[1][0]  
  obj[obj.AddUserData(childGrp_Item2)] = 55.6  
    
  c4d.EventAdd()

Thank you, Scott.
The documentation is not very clear in how to achieve that.

I contacted Maxon and I was told to create a group and set DESC_PARENTGROUP = c4d.DescID(0)
Then, all my interface elements need to be set to DESC_PARENTGROUP] = obj.GetUserDataContainer()[0][0]
Also, it seems that the c4d.DESC_COLUMNS constant is not set properly in the coffeesymbols.h file. However, it is correct (value of 22) in the lib_description.h file.

Thank you Rick Barret

Do you have a small example of using c4d.DESC_COLUMNS Rui?
I'm not sure how to use that one.

Actually, I didn't used multi-columns after all.
But I may try to make it work with my plugin.

Here is the code I used:

rootGroup = c4d.GetCustomDatatypeDefault(c4d.DTYPE_GROUP)
rootGroup[c4d.DESC_NAME] = "Presets"
rootGroup[22] = 3
rootGroup[c4d.DESC_PARENTGROUP] = c4d.DescID(0)
node.AddUserData(rootGroup)

ud_presets=c4d.GetCustomDataTypeDefault(c4d.DTYPE_LONG)
ud_preset[c4d.DESC_NAME] = "Presets"
ud_preset[c4d.DESC_CUSTOMGUI] = c4d.CUSTOMGUI_CYCLE
ud_preset[c4d.DESC_PARENTGROUP] = node.GetUserDataContainer()[0][0]
file_list=get_file_list()
datalist=c4d.BaseContainer()
for i,f in enumerate(file_list) :
datalist.SetData(i,f[:-4])

ud_preset[c4d.DESC_CYCLE] = datalist

presets=node.AddUserData(ud_preset)
node[presets]=0

ud2=c4d.GetCustomDataTypeDefault(c4d.DTYPE_BOOL)
ud2[c4d.DESC_NAME] = "Use preset"
ud2[c4d.DESC_CUSTOMGUI] = c4d.CUSTOMGUI_BUTTON
ud2[c4d.DESC_PARENTGROUP] = node.GetUserDataContainer()[0][0]
button1=node.AddUserData(ud2)
node[button1]=False

ud3=c4d.GetCustomDataTypeDefault(c4d.DTYPE_BOOL)
ud3[c4d.DESC_NAME] = "Store new preset"
ud3[c4d.DESC_CUSTOMGUI] = c4d.CUSTOMGUI_BUTTON
ud3[c4d.DESC_PARENTGROUP] = node.GetUserDataContainer()[0][0]
button2=node.AddUserData(ud3)
node[button2]=False

It creates a 3 column parent group, that also changes the same of the UserData tab.

Thanks Rui. !Beer[URL-REMOVED]
Added these to my notes.

Now I just have to figure out how to do these in C++.
That's going to be another wonderful adventure.
