fill quicktab in userdata

    Hello there,

    I am trying to modify existing quicktab radio buttons in userdata with Python.
    Example: There is a varying number of objects in a parent. The number of tabs in the quicktab should correspond to the number of children and the captions should at least show their index/number of the child .

    I 'm familiar with the basics of getting and setting userdata, appending items to lists, etc. Have been trying hard to do this for quite a while and any hint is greatly appreciated.

    Hi,

    To fill the cycle options for the quick tab user data you need to retrieve its description container and change DESC_CYCLE entry. It is a container with the entry integer value and string caption:

    data = op.GetUserDataContainer()
      
    # Get user data description id and data container
    descid = data[0][0]
    bc = data[0][1]
      
    # Build new cycle options container
    cycle = c4d.BaseContainer()
    cycle[0] = "Tab 1"
    cycle[1] = "Tab 2"
    cycle[2] = "Tab 3"
    cycle[3] = "Tab 4"
    cycle[4] = "Tab 5"
    bc[c4d.DESC_CYCLE] = cycle
      
    # Set modified description data container
    op.SetUserDataContainer(descid, bc)
      
    # Notify Cinema 4D for changes
    c4d.EventAdd()

    Thank you Yannick!!!

    I am having a hard time understanding that description id stuff. It's about items in the baselist containers, I know. Just can't REALLY figure it out from the SDK, so far. Can you give me a hint, where I find a comprehensive explanation?

    Anyway - your help is much appreciated and I will keep learning.

    Cheers, Wolf

    Quicktab dynamically filled:

    Got it to work and thought, I share...
    I call this as a user script and not inside a Python tag since the number of children does not change often during projects. I'll eventually use a button and the message() function in the userdata but that seems to be too much of a distraction here.

    Thanks again for the input.

    Thanks for sharing your final working script.

    A parameter description or user data description container for objects holds all the information for the display of these parameters in the Attribute Manager. The IDs of the entries in this description container are defined in DESC values.

    Python currently only supports the modification of user data description with BaseList2D.GetUserDataContainer()/BaseList2D.SetUserDataContainer().
    And it returns a read-only Description object for a base list allowing to browse through all of its parameters.
