    i searched for show/hide of description elements, but didnt understand what i found.. so i wonder if there is any example how i can show/hide groups of my description, based on selections made?

    thanks for your help...

    You will need to implement GetDDescription() and set it:

    BaseConainer bc;
    bc.SetBool(DESC_HIDE, FALSE); // or TRUE
    description->SetParameter(DescLevel(id,DTYPE_BLAH,0L), bc, DESCID_ROOT);

    args, i guess i still dont get it... how do i implement that GetDDescription()

    and if i have this:
    DescLevel(V_COUNT,DTYPE_VECTOR, LONG t_creator )

    what is that t_creator about?
    and why do i get an error that V_COUNT is not declared? it is an element of my gui..

    or is there an example somewhere in the c4dsdk which i could look at?

    thanks and cheers,

    Did you declare V_COUNT in the .h file of your plugin class and include the .h file in the .cpp?

    It might be that you aren't loading the static descriptions first in GetDDescription(). Here's an example to help:

    // NodeData.GetDDescription - Descriptions and Parameters
    //*---------------------------------------------------------------------------*
    Bool MyPluginClass::GetDDescription(GeListNode* node, Description* description, LONG& flags)
    //*---------------------------------------------------------------------------*
    {
         if (!(node && description))               return FALSE;
         if (!description->LoadDescription(node->GetType())) return FALSE;

    BaseContainer     bc;
         bc.SetBool(DESC_HIDE, TRUE);
         if (!description->SetParameter(DescLevel(V_COUNT,DTYPE_VECTOR,0L),     bc, DESCID_ROOT))     return FALSE;

    flags |=     DESCFLAGS_DESC_LOADED|DESCFLAGS_DESC_RECURSIONLOCK;

    return SUPER::GetDDescription(node,description,flags);
    }

    I don't think you need to worry about LONG t_creator. Simply set it to 0L.

    You are not doing something correctly then. This is standard (I use it in about six GetDDescriptions() in one project made of many plugins). You have to have "c4d.h" included somewhere and the api.lib as part of your project. Also, this method is an override from NodeData. Can't be used in any class, only those derived from NodeData at some level.

    0L is a LONG 0 value. This avoids the compiler adding conversion code from INT to LONG (as numbers without the 'L' will be considered INT by default).

    and i still get the same "error C2653"

    furthermore i dont even know how to finally call the function to hide my gui element

    any help to get this working would be great

    You can't call GetDDescription(). It is called as needed - changes made to Descriptions in SetDParameter() or Message() may trigger it (as well as user changes similarly).

    There are several ways to do the hiding as well. I'm using a couple more, like:

    BaseContainer* bc = description->GetParameterI(DescLevel(V_COUNT), NULL);
    if (bc)     bc->SetBool(DESC_HIDE, !show); // Bool show;

    or

    BaseContainer bc = GetCustomDataTypeDefault(DTYPE_VECTOR);
    bc.SetBool(DESC_HIDE, !show);
    if (!description->SetParameter(...))

    Make sure that the groupid argument in description->SetParameter() is correct! If the description is under a group, this must be the direct group underwhich it resides.

    Not sure why SUPER isn't working for you. To verify that I'm correct (as always ;) ), just go to GetDDescription() in the SDK documentation and there it is - it is required. Do this in your plugin object class header:

    class MyPlugin :: public ObjectData
    {
    INSTANCEOF(MyPlugin,ObjectData)

    I think that the line in red is needed for SUPER to work. Because of multiple inheritance, C++ doesn't have a super:: operator to get at the base class of derived classes. This is a workaround in the C4D C++ SDK to do so.

    another thing i cannot find.. how can i get the content of an element?

    for example how can i get the value of V_COUNT inside the description? or how can i check if the user has dropped something into a link field?

    ok. i now use private variable to be able to check them in the description. this works.. but the AM doesnt update correctly. i found a thread here which makes me think i have to use:
    SendCoreMessage COREMSG_CINEMA_FORCE_AM_UPDATE
    but i still need to find out how to use that...

    ok..
    this is what i have now, it works, but is it the right way to do it?

    That looks correct on showing/hiding the parameters.

    Get at the values of your description parameters using the BaseContainer of your node (which requires casting up since GetDataInstance() is declared in BaseList2D). So you usually get a GeListNode* node in the NodeData methods. Do this:

    BaseContainer* bc = static_cast<BaseList2D*>(node)->GetDataInstance();
    bc->SetLong(V_COUNT, 1000L);
    - or -
    LONG vcount = bc->GetLong(V_COUNT);

    If you are getting the BaseObject* op in ObjectData, simply call:

    BaseContainer* bc = op->GetDataInstance();
