Progressbar as in stretch~

danieleghisi

Hello everyone,

is there a way to produce in a 3rd party external a progressbar on the object box (for vanilla objects), such as the one shown by [stretch~]?

Thanks,
Daniele

Hi,

I just added an example of how to do this in the Min-DevKit here: https://github.com/Cycling74/min-devkit/blob/master/source/projects/min.progress/min.progress.cpp

Hi Tim, thanks for pointing that out. The Min framework looks amazing, but I have coded my own package via the C api. Is there a way I could access this function from the standard SDK?
I've seen that in your Min code there's a box() function (which I assume returns the object box?) to which something like a "startprogress" message is to be sent, I imagined that box() may be somehow an higher level abstraction upon the C api, but I cannot seem to find in the github repository the layer where box() is implemented...

Thanks again,
Daniele

Yes,

The box() method returns the object's box. You can do this in the traditional SDK with a call to object_obex_get() and using #B as the key. You can then send messages using `object_method()`.

Cheers,
Tim

Hi Tim, fantastic, that settles it. I had explored it that route but I was using a pointer to an atom, whereas object_method() seems to need a pointer to a t_atom_float to work.

Thanks again, this is very handy.

For someone who might look how to create the animation with diagonal stripes - loader or waiting style - like [rnbo~] uses for example when preparing the compilation:

Starting the animation:

number current_progress {-1.};
auto b = this->box();
b("startprogress", &current_progress);

Stopping the animation:

auto b = this->box();
b("stoptprogress");
