Changing a box size in presentation view
Jan 20 2011 | 11:10 pm
This only works in regular view. How do I make this work in presentation view?
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();
}

- Jan 20 2011 | 11:24 pmI do this outside js with a presentation_size message or with a presentation_rect message...
- May 18 2022 | 5:34 amAnyone 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 this.patcher.box.rect but I can't find the equivalent message so that this resize also applies in presentation mode. Any ideas? Thanks !

- May 18 2022 | 1:31 pmThank you @11OLSEN ! 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. function bang() { post("sent a bang"); 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); }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... :(
- May 18 2022 | 1:50 pmIf 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); } - May 18 2022 | 2:23 pmWow excellent thank you so much it works now. I had no idea you could assign a varname from the inside like this, pretty slick !
- May 18 2022 | 2:49 pmSorry , 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 js -1407374883553280Do 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.
