InExclude in a CommandData plugin [SOLVED]

Hey everyone. I am writing a command data plugin, well, updating an old one i made forever ago, and I am trying to add in some stuff with inexclude boxes so I can have groups of objects. The ultimate goal is to simple iterate over the objects that are placed in the inexclude box and do stuff to them, in my case, adding tags to them. I've been screwing with this for several hours with no luck.

I have created a simple stripped down plugin to help get this working, it is just an inexclude box and a button to print stuff to the console. It helps illustrate what I am trying to do. The code is below, as well as a link to the plugin files to mess with.

I used this thread for creating the in/exclude box.

i have my main plugin setup and ready, but getting objects from the inexclude box is giving me issues
  
I found this video from Pim Grooff but it does not seem to be helping me with a CommandData plugin



  
in it, he is using a tag plugin, using a node instance with data = tag.GetDataInstance() then later
using inex = data[MY_LISTBOX] where MY_LISTBOX is the description from the res file of the inexclude gui element
  
he can then use inex.GetObjectCount()
I cannot figure out how to get that far. Nothing I do seems to work. I simply want to be able to grab the
objects in the box.

Hi Charles,

An InExcludeCustomGui could be added to a dialog layout in pre R18 versions but its data couldn't be changed and retrieved.
R18 brought the new methods BaseCustomGui.GetData()/BaseCustomGui.SetData() that enable to obtain and set a custom GUI data (InExcludeData in the case of the InExcludeCustomGui). Note all custom GUIs inherit BaseCustomGui.

# this gives me an error, AttributeError: 'module' object has no attribute 'GetParameter'
# box = c4d.GetParameter(5001, c4d.DESCFLAGS_GET_0)

This gives an error because GetParameter() is called on the c4d module. This function has to be called on a node or object in the document.

if c4dversion >= 16 :
    # C4DAtom.GetParameter(id, flags) was added in 16.021 but that returns and error for me
    pass
  
if c4dversion >= 18:
    # apparently in r18 you can use Description.GetParameter(id, ar) but im not getting that to

The InExcludeCustomGui in a dialog doesn't store its data in a parameter like an InExclude parameter of an object. Descriptions and dialogs are different:
Node plugins (ObjectData, TagData etc.) use a description resource to declare parameters and to provide a UI for the Attribute Manager.
Dialogs use a dialog resource or a manual layout in GeDialog.CreateLayout().

To retrieve the InExcludeCustomGui data call BaseCustomGui.GetData() (only available in R18) :

box = self.inexbox
if box is not None:
    data = box.GetData()
    print data

Yannick,

Thanks for the help. I tried out your code in r18 and it works just like I would expect. It really sucks you can't access the data in earlier versions but oh well. I will just enable this feature for r18 and up and think of something else for earlier versions of cinema. Maybe I will skip it for earlier versions all together for now; not sure yet.

Thanks again dude
