Hi
The documentation is a bit unclear what "data" in

    
    
      
    
    
    
    PrefsDlg_Base::SetValues(BaseContainer* data)

and

    
    
      
    
    
    
    PrefsDlg_Base::CommandValues(LONG id, const Basecontainer &msg,BaseContainer* data)

and

    
    
    
    
    PrefsDlg_Base::EnableValues(BaseContainer* data)

actually is.
After 2 hours of messing around, i found out that it is simply the WorldContainer. What i do now is:

    
    
    
    
    SetValues(BaseContainer* data)
    
    
    
    
    {
    
    
    
    
         if(!data) return;
    
    
    
    
          data = data->GetContainerInstance(PLUGIN_ID);
    
    
    
    
         if(!data) return;
    
    
    
    
         ...
    
    
    
    
         ...
    
    
    
    
    }

The Examples in the docs are very much misleading since the code in MyPrefsDialog assumes that you store data directly in the worldcontainer. While the code in MyPrefs assumes that you store data in a Container which itself is stored in the WorldContainer.

I do it something like this. Here is a snippet of my prefs for DPIT:

class MyPrefsDialog : public PrefsDlg_Base //Dialog  
{  
  
private:  
     DpitSubPrefs *s_dpit_dlg;  
     IconArea ua;  
public:  
       
    MyPrefsDialog(PrefsDialogHookClass* hook) : PrefsDlg_Base(IDD_DPIT_PREFS, hook)   
     {   
            
     }  
      
    virtual void SetValues(BaseContainer *data)  
    {  
      if (!data) return;  
      SetBool(IDC_BARBEGIN, data, PREFS_SLIDERAT0);  
        
     }  
     virtual Bool CreateLayout()  
     {  
          Bool res = LoadDialogResource(IDD_DPIT_PREFS,NULL,0);  
          AttachUserArea(ua,IDC_ICONAREA);  
          return res;  
     }  
      
    virtual void EnableValues(BaseContainer *data)  
    {  
    }  
      
    virtual LONG CommandValues(LONG id, const BaseContainer &msg;, BaseContainer *data)  
    {  
     switch (id)   
     {       
     case IDC_BARBEGIN: GetBool(id, data, PREFS_SLIDERAT0); break;  
                      
                }  
      return TRUE;  
    }       
};

So.. i would say this means that you store all your data in the Worldcontainer without putting it in a "sub" Container. At least i'm very sure this was the case for me.
There is one thing i would like to know. If you do it like this, how do you retrieve your prefs data outside of the Prefs Dialog.
I simply do ...
Basecontainer *prefs = GetWorldContainerInstance()->GetContainerInstance(PLUGIN_ID);
... and i can do this everywhere in my code.

Btw. i have a pretty cool "ScanContainer" function that prints all data in a Container to the DebugConsole using GeDebugOut.
Anyone interested might have a look

Samir you could use it to scan your "data" container to see if it's really what you expect.

yes, I am reading it out elsewhere in the code too by simply accessing the world container as you do.

Hehe, I also have a similar Scan Container function, but I am using the BrowseContainer Class for this.

But surely someone can use this. Thanks for sharing

But in
    virtual void SetValues(BaseContainer *data)
    {
      if (!data) return;
      SetBool(IDC_BARBEGIN, data, PREFS_SLIDERAT0);

     }
isnt "data" the WorldContainer with lot's of other stuff ??
For me it is 8-o

yes, why? IDC_BARBEGIN is a unique ID, that way I make sure I am not running into conflicts (hopefully, if other people use unique IDs too).

Hmm... ok.. how do you get a unique ID ? Is it your plugin ID ? What if you want to store more than one Boolean ? You need unique iD's for all your variables ??!!

yeah, for each one. I get all from the plugin cafe here. There is maybe a range that is never used (for example you could just use an imaginary number that is very high, like: 94560345743267 and then just count up for all your variables. I doubt anybody else will ever have this exact same number in use in conjunction with the worldcontainer You just need to go sure that you are not overwriting any of c4ds values.)

well.. btw.. i found out that the "BaseContainer *data" isn't probably a pointer to the realy WorldContainer, but to a copy of the worldcontainer. It seemed to me that reading and writing to this Container only changes things in the PrefsDialog (?!). So I've changed my code again, and it should finally work...
