The widget in the 3D scene

I draw 3D scene and I have to draw the 2D button over 3D scene.

LOAD

Code:


//2D
   SIO2stream *_SIO2stream = sio2StreamOpen( "checkerplate.png", 1 );
   
   if (_SIO2stream != NULL)
   {
   
   _SIO2widget    = sio2WidgetInit  ( "button" );
   _SIO2material  = sio2MaterialInit( "button" );
   _SIO2image      = sio2ImageInit  ( "button" );
   
   sio2ImageLoad( _SIO2image, _SIO2stream );
   sio2ImageGenId( _SIO2image, 0, 0.0f );
   
   _SIO2widget->_SIO2material = _SIO2material;
   _SIO2material->_SIO2image[  SIO2_MATERIAL_CHANNEL0 ] = _SIO2image;
   _SIO2material->blend = SIO2_MATERIAL_ALPHA;
   
   _SIO2widget->_SIO2transform->scl->x = _SIO2image->width;
   _SIO2widget->_SIO2transform->scl->y = _SIO2image->height;
   
   _SIO2widget->_SIO2transform->loc->x = 20.0f;
   _SIO2widget->_SIO2transform->loc->y = 20.0f;
   
   _SIO2stream = sio2StreamClose( _SIO2stream );
   }


DRAW

Code:


if (_SIO2widget != NULL)
   {
      sio2WindowEnter2D( sio2->_SIO2window, 0.0f, 100.0f );
      {
         sio2WidgetRender( _SIO2widget, sio2->_SIO2window, 0 );
      }
      sio2WindowLeave2D();
   }


It is crashed when call sio2WidgetRender( _SIO2widget, sio2->_SIO2window, 0 );
Can I draw the widget in the 3D scene?

To answer that question again...have you turned off png compression in the project settings of Xcode?

I turned off but it did not help...

Heuuuu dude have you initialized the widget system? sio2WidgetInit... check tutorial07

Thnx...
