Hi
Is it possible to add User Data (as in the User Data tab of the Attributes window) to an object that is created in my code? I guess you use GetDynamicDescription to access existing User Data.
Thanks

Exactly. You can use DynamicDescription::Alloc(), passing the user-data's description as a
BaseContainer, to append a new user-data parameter. The description ID of the new parameter
will be returned.

Thanks NiklasR
I am currently trying to find example code and wading through the docs to find how to actually do this.
My understanding is a bit nebulous at this point.

Thanks. That made it much clearer. The ways of the SDK are often very mysterious to me.

And promptly a new question pops up.
How can I create groups? Or, actually I did create a group like this:
bc = GetCustomDataTypeDefault(DTYPE_GROUP);
bc.SetString(DESC_NAME, "General");
bc.SetString(DESC_SHORT_NAME, "General");
bc.SetBool(DESC_GUIOPEN, TRUE);
bc.SetBool(DESC_TITLEBAR, TRUE);
desc->Alloc(bc);
But how to I move my other data into the group?
Do you use DESC_PARENTGROUP, DESC_PARENTID?

Small example without any error checking stuff:

BaseDocument *doc = GetActiveDocument();
BaseObject *obj = doc->GetActiveObject();
DynamicDescription* dd = obj->GetDynamicDescription();
BaseContainer groupContainer;
dd->FillDefaultContainer(groupContainer, DTYPE_GROUP, "New Group");
DescID groupID = dd->Alloc(groupContainer);
dd->Set(groupID, groupContainer, obj);
BaseContainer realContainer;
dd->FillDefaultContainer(realContainer, DTYPE_REAL, "New Real");
GeData dataID;
dataID.SetCustomDataType(CUSTOMDATATYPE_DESCID, groupID);
realContainer.SetData(DESC_PARENTGROUP, dataID);
DescID realID = dd->Alloc(realContainer);
dd->Set(realID, realContainer, obj);

Great. That works although I am not sure I would have come up with it. In retrospect it looks logical.
Thanks

And here we go again. I find DynamicDescription dramatically confusing because references to it are all over the place in the documentation. I understand groups now but I am stuck at how to implement a Popup menu. I suppose you use DTYPE_POPUP to make a container for the menu and use DESC_CYCLE to populate it?
On 10/09/2013 at 01:30, xxxxxxxx wrote:
With "Popup menu", do you mean a Cycle field? The elements in a Cycle field are described using a
BaseContainer. Take a look at the documentation of the Description class, all IDs are listed up there
with quite good description.
BaseContainer cycle;
cycle.SetString(0, "Cycle Value 0");
cycle.SetString(1, "Cycle Value 1");
itemdesc->SetContainer(DESC_CYCLE, cycle);
Best,

The popup button doesn't seem to work like the ComboButton Nik.
It's either broken. Or the the way we populate it with entries is different.
Example that adds a UD ComboButton to the active object:
BaseObject *obj = doc->GetActiveObject();
if (!obj) return FALSE;
//Create a list of ComboButton values
BaseContainer names;
names.SetString(0,"Scott");
names.SetString(1,"Nicklas");
BaseContainer bc = NULL;
bc.SetString(DESC_NAME, "My Combo");
bc.SetString(DESC_SHORT_NAME, "My Combo");
bc.SetLong(DESC_CUSTOMGUI, CUSTOMGUI_CYCLEBUTTON); //<--- put CUSTOMGUI_POPUP here and it no longer works!!!
bc.SetContainer(DESC_CYCLE, names);
//Get the object's master UD container that holds all the UserData entries
DynamicDescription *dd = obj->GetDynamicDescription();
if(!dd) return FALSE;
//Create a new UserData entry using the container values above
dd->Alloc(bc);
SendCoreMessage(COREMSG_CINEMA, BaseContainer(COREMSG_CINEMA_FORCE_AM_UPDATE)); //Refresh the AM to see the changes in real time
EventAdd();
