Hi,

I've built my own preferences category with PrefsDialogHookClass as outlined in the SDK documentation. But: How can I retrieve these data? I need them outside of the preferences dialog. Where can I get a pointer to the BaseContainer with my preference data?

Thanks in advance!

Regards,
jl

Use PrefsDialogHookClass::GetData() on the allocated instance. (Or store your preferences somewhere else that in the supplied container, for example with SetWorldPluginData().)

SetWorldPluginData has a wrong declaration in c4d_general.h: The "const" for the second parameter is missing. This causes a linker error.

Even with the "const" added, I can't get SetWorldPluginData to work. It seems to write an empty container.

Oops, by mistake I used the 8.0 SDK. In the 8.1 SDK the "const" is in place. But the rest still doesn't work!?!

Hi,
it works fine for me here. Here is a snipped that should work:
BaseContainer *wpdo = GetWorldPluginData(PLUGIN_ID);
if(wpdo) GePrint(wpdo->GetString(1111));
BaseContainer wpd;
wpd.SetString(1111,"Works fine");
SetWorldPluginData(PLUGIN_ID,wpd,FALSE);
Hope that helps

yes, that´s true because they are only preferences If you want to have a constant "background" check you could use the SceneHookData class.
For some information: I have just recently answered a question here in the forum about the registration of it.

Hi,

the BaseContainer that I store with SetWorldPluginData doesn't live long enough.

I want to set it inside CommandValues:

  
LONG FXPrefsDialog::CommandValues(LONG id, const BaseContainer &msg;, BaseContainer *data)  
{  
     String editorPath;  
     if(!GetString(IDC_EDITOR_PATH, editorPath))  
          return FALSE;  
  
     BaseContainer bc;  
     bc.SetString(10000, editorPath);  
     SetWorldPluginData(ID_PREFERENCES, bc);  
  
     MessageDialog(GetWorldPluginData(ID_PREFERENCES)  
          ->GetString(IDC_EDITOR_PATH)); // This works!  
  
     return true;  
}  

But from elsewhere GetWorldPluginData(ID_PREFERENCES) always returns NULL. For example, here:

  
void FXPrefsDialog::SetValues(BaseContainer *data)  
{  
     String editorPath;  
  
     BaseContainer* bc = GetWorldPluginData(ID_PREFERENCES);  
     if(bc != NULL)  
     {  
          editorPath = bc->GetString(10000);  
     }  
     else  
     {  
          BaseContainer bc;  
          SetWorldPluginData(ID_PREFERENCES, bc, FALSE);  
     }  
  
     SetString(IDC_EDITOR_PATH, editorPath);  
}

I give up!

1. PrefsDialogHookClass::GetData() won't work until the preferences dialog has been opened at least once in the Cinema 4D session.

2. GetWorldPluginData receives a NULL pointer if it's not executed quite immediately after SetWorldPluginData.

3. SceneHook doesn't seem to be offer a straightforward solution.

So now I wrote code for a preferences file of my own.

I cannot confirm 2). The following code seems to work:

    
    
    Bool MenuTest::Execute(BaseDocument *doc)  
    {  
      {  
        BaseContainer* bc = GetWorldPluginData(1012173);  
        if (bc)  
        {  
          GePrint("before: " + bc->GetString(101));  
        }  
      }  
      {  
        BaseContainer bc;  
        bc.SetString(101, "Hello World!");  
        SetWorldPluginData(1012173, bc, FALSE);  
      }  
      {  
        BaseContainer* bc = GetWorldPluginData(1012173);  
        if (bc)  
        {  
          GePrint("after: " + bc->GetString(101));  
        }  
      }  
      return TRUE;  
    }  
    

This first time I ran it only "after" was output, but after that "before" is output as well, even after closing C4D. (At first I thought it didn't work, since when I forced C4D to quit it didn't save the preferences. Perhaps you did that as well?)
You're probably right about 1). I think that the internal preference panes store their data in the GetWorldContainer() space, so perhaps that's where your data ends up as well. (The preference library was originally only used by internal modules.) But using GetWorldPluginData() sounds safer, if it works.
