    Hi,

    I'm trying to figure out how to hide a parameter in an object generator plugin, but I can't for the life of me figure out how to do this or how to get a pointer to some UI widget to hide one of it's children. 
    The whole plugin UI is created using description resources ".res, str..etc" files.

    This makes cinema 4d create a UI based on these files, does c4d has another way of creating the UI the ordinary way ?

    like creating a widget -> add child widgets -> set child widgets properties..etc ?

    What I am trying to achieve is to show some parameters based on a selection in a tree widget and
    to hide them if the tree widget doesn't have selection.

    Thanks in advance.

    I figured it out, apparently I can dynamically add/modify parameters to descriptions at runtime
    by overriding GetDDescription() function and using the following steps to hide the desired parameter:

    //Get the desired parameter
    1-Description::GetParameterI(const DescID &id, AtomArray *ar)

    //Hide it
    2- BaseContainer::SetBool(DESC_HIDE, true);

    Hi Mohamed,

    welcome to the Plugin Café forums 🙂

    I'm glad, you already found the right approach yourself.
    A few additional thoughts:
    - You can not only hide single widgets, but also for example groups of them.
    - Instead of hiding certain widgets, you also have the option of creating widgets only under certain conditions.

    The C++ docs contain a bunch of manuals related to this topic under "Overviews -> Application Development -> GUI and User Interaction":
    Description Manual
    Description Settings Manual

    Hi Andreas,

    thanks for the additional info, I have already found those pages on the manual yesterday.

    Thanks again.

    hi there...

    is there an easy possibility to hide an userdata element
    in a multi column group with multiple rows,
    without messing up the layout?

    example:

    --> setup 2 columns
    A1 B1
    A2 B2
    A3 B3

    --> goal hide B1
    A1
    A2 B2
    A3 B3

    --> reality B1 hidden
    A1 A2
    B2 A3
    B3

    Hi,

    one way would be to have three groups with two columns each.
    Another option instead of hiding might be to disable parameters.
    Would be interesting to know in which context you want to achieve this?

    i made my userdata in the app (not by code) ....
    its just a python tag and i wanted to hide an element
    setting a group to 2 columns and adding 2 groups inside sadly doesnt give me 2 columns :/
    maybe i gotta try to make a real tag plugin

    Sorry, I probably should have explained a bit more in detail.
    I thought of something like this (each of the three groups G1 to G3 set to two colums) :

    - G1
       \+ A1
       \+ B1
    -G2
       \+ A2
       \+ B2
    - G3
       \+ A3
       \+ B3
