    Hi Folks,

    I've got myself a dialog spline gui, but I'm a bit lost as to where to put/add the data for it. Is this done in the GetDDescription()? And can the data be added or dynamically changed from elsewhere (another function)?

    EDIT: this is what I tried inside the GetDDesctipion() :

      
    SplineData* sData;   
    sData->Alloc();   
    sData->InsertKnot(0,0,0);   
    sData->InsertKnot(1,1,0);   
    MySpline->SetSpline(sData); // MySpline is the customgui element   
    MySpline->Redraw();   
    sData = NULL;   
    GeFree(sData);

    You initialise the spline in your plugin's Init routine. Here's the complete initialisation function from one of the X-Particles' modifiers:

      
    // this is called from ObjectData::Init()   
    void XModSpeed::InitSpline(BaseContainer *data)   
    {   
         SplineData *spd = NULL;   
         CustomSplineKnot *knot;   
         GeData d(CUSTOMDATATYPE_SPLINE, DEFAULTVALUE);   
      
         spd = (SplineData* )d.GetCustomDataType(CUSTOMDATATYPE_SPLINE);   
         if(spd)   
         {   
              spd->SetRange(0.0, 1.0, 0.01, 0.0, 300.0, 1.0);   
              spd->MakeLinearSplineBezier(2);   // 2 knots   
      
              knot = spd->GetKnot(0);   
              knot->vPos = Vector(0.0, 150.0, 0.0);   
              knot->lFlagsSettings |= FLAG_KNOT_LOCK_X|ADD_KNOT_ADAPT_TANGENTS;   
              knot->vTangentRight = Vector(0.1, 0.0, 0.0);   
              knot = spd->GetKnot(1);   
              knot->vPos = Vector(1.0, 150.0, 0.0);   
              knot->lFlagsSettings |= FLAG_KNOT_LOCK_X|ADD_KNOT_ADAPT_TANGENTS;   
              knot->vTangentLeft = Vector(-0.1, 0.0, 0.0);   
      
              data->SetData(XMSP_SPEED_SPLINE, d); // replace the ID with your resource element   
         }   
    }   
      
    

    The flag settings for the knots you can find in the SDK.

    This brings up something that trips me up a lot with GeDialogs.
    When you want to change a gizmo using a BaseContainer for a node based plugin. You simply grab the node. Then assign the BaseContainer to it like this:

        BaseTag  *tag  = (BaseTag* )node;  
      BaseContainer *data = tag->GetDataInstance();
    

    Then when you want to change the gizmo (Like adding spline knots to it). You simply change the BaseContainer then updated those changes using SetData().

    But when you're using a GeDialog to host the gizmo. There's no node to use. So you can't use the BaseContainer the same way as you use it on a node based plugin like tags and objects.
    So even though I can add the SplineGUI gizmo itself to my GeDialog. I can't do anything to it like add any points to it. Because I don't know the dialog equivalent version of this code: BaseContainer *data = tag->GetDataInstance();

    This trips me up all the time when using GeDialogs.

    #Edit- Never mind. I've figured out how to get it working.
