This only works in regular view. How do I make this work in presentation view?

if(isNaN(this.patcher.parentpatcher)==0){return;}

function list(a)
{
if(isNaN(this.patcher.parentpatcher)==0){return;}
var myrect =this.patcher.box.rect;
var width = arguments[0];
var height = arguments[1];
myrect[2] = myrect[0]+width;
myrect[3] = myrect[1]+height;
this.patcher.box.rect = myrect;
post("resizing bcanvas to",myrect);
post();
}

I do this outside js with a presentation_size message or with a presentation_rect message...

Anyone else has a solution for this? Working from the outside doesn't work from me I'm dealing with a library of bpatchers. I already can resize them dynamically with 

but I can't find the equivalent message so that this resize also applies in presentation mode.

Any ideas? Thanks !

For whatever reason you have to work with a scripting message for pres mode positioning of bpatchers:

this.patcher.message("script", "sendbox", "scrname", "presentation_rect", boxpos);

You can also set "presentation_size" or "presentation_position" using only two values.

var boxpos = new Array(4);
boxpos[0] = 50
boxpos[1] = 50
boxpos[2] = 150
boxpos[3] = 150
this.patcher.message("script", "sendbox", "scrname", "presentation_rect", boxpos);

I just tried (unsuccessfully) to integrate this. I'm not sure what I'm missing.

I put this in a js object, inside the test abstraction I call with my bpatcher.

    this.patcher.message("script", "sendbox", "scrname", "presentation_rect", boxpos);

Now from the outside (in my main patch, which contains the bpatcher), I switch to presentation mode, click the bang inside the bpatcher but nothing happens.

Could you maybe give me a small example patch or show me what I'm missing??

Now I'm worried about the "scrname" part, is that a variable I don't know about or should I give the bpatcher an explicit name?... That would be kind of a deal breaker for me. I'm making a bpatcher library i.e. all my objects can be called many times. I can't really expect users to add a scripting name for each instance for this to work... :(

Thank you @11OLSEN !

If you are inside the bpatcher you have to add "parentpatcher". That's the one containing and scripting the bpatcher. And you could assign random names automatically to get around the varname problem.


function bang()
{
    post("sent a bang");

    var thevarname = this.patcher.box.varname;
    // making sure the bpatcher has a scripting name 
    if (thevarname=="")
        this.patcher.box.varname = thevarname = "bp" + Math.floor(Math.random() * Date.now());
    
     var boxpos = new Array(4);
    boxpos[0] = 50
    boxpos[1] = 50
    boxpos[2] = 150
    boxpos[3] = 150
    this.patcher.parentpatcher.message("script", "sendbox", thevarname, "presentation_rect", boxpos);
}

	boxpos[0] = 50
	boxpos[1] = 50
	boxpos[2] = 150
	boxpos[3] = 150
	this.patcher.parentpatcher.message("script", "sendbox", thevarname, "presentation_rect", boxpos);
}

Wow excellent thank you so much it works now.

I had no idea you could assign a varname from the inside like this, pretty slick !

Sorry , I realize there's something else I'm missing here.

Do you know by any chance how I can retrieve the curent presentation rect of the bpatcher, also from the inside?

I tried adding this line I found on an older topic 

outlet(0,this.patcher.getattr("presentation_rect"));

but it returns something strange like this

Do you know another way to do this by any chance?

My toggling system circles between different sizes of the bpatcher (to hide/reveal settings for instance) and I need to keep the object's location for it to work properly.

this.patcher.box.rect will give you the right values depending on which view you are in.
