when double-clicking the [send] object, a popup-menu allows to flash-highlight all matching instances of [send]/[receive] objects created in a patcher.

I would like to achieve the same effect for a specific custom class of externals that I have just completed.

I couldn’t find anything about it in the SDK documents or anywhere online.

Can someone explain or post a short code snippet to show how to accomplish this operation?

did you find a solution for highlighting objects from the C API ?

I would like to do the same 4 years after...

no, nobody from Cycling74 ever replied to my inquiry, so I haven't found a solution for this.

Hi Antoine,
no, nobody from Cycling74 ever replied to my inquiry, so I haven't found a solution for this.

on my side, I've implemented kinda workaround by changing the box color for few sec

highlight_objects.mov

t_max_err err = object_obex_lookup(this, gensym("#B"), (t_object **)&box);

m_highlight_clock = clock_new(this, (method) object_base::reset_color);

void object_base::reset_color(object_base* x)

t_max_err err = object_obex_lookup(x, gensym("#B"), (t_object **)&box);

void object_base::highlight()
{
  if(m_highlight_clock)
    return;

  t_object *box{};

  // get the object's wrapping box
  t_max_err err = object_obex_lookup(this, gensym("#B"), (t_object **)&box);
  if (err != MAX_ERR_NONE)
    return;

  err = jbox_get_color(box, &m_color);
  if(err != MAX_ERR_NONE)
    return;

  // invert the color
  t_jrgba new_color;
  new_color.alpha = 1.0;
  new_color.red   = 1.0;
  new_color.green = 0.0;
  new_color.blue  = 0.0;

  jbox_set_color(box, &new_color);

  m_highlight_clock = clock_new(this, (method) object_base::reset_color);
  clock_delay(m_highlight_clock, 2000);
}

void object_base::reset_color(object_base* x)
{
  t_object *box{};

  // get the object's wrapping box
  t_max_err err = object_obex_lookup(x, gensym("#B"), (t_object **)&box);
  if (err != MAX_ERR_NONE)
    return;

  jbox_set_color(box, &x->m_color);
  object_free(x->m_highlight_clock);
  x->m_highlight_clock=nullptr;
}
