Hi there, I am trying to put together a bit of js scripting to allow control over a subpatchers window so I can open it, close it, resize it etc.

I have attached a small project that shows the methods I am trying without results.

autowatch = 1;
inlets = 1;
outlets = 1;

var thisPat = this.patcher;
var findObj = {//object to handle location of an object in a patch
        nameToFind: undefined,
        foundObj: undefined,
        findTheObj: function (a) {
        if (a.varname === findObj.nameToFind) {
                findObj.foundObj = a;
            }
        }
    };

function getPat() {//DOES NOT WORK AS SUBPATCH DOESN'T HAVE WIND?
    var thePatch, patWind;
    
    //get 'thePatch' object
    findObj.nameToFind = 'pat';
    thisPat.apply(findObj.findTheObj);
    thePatch = findObj.foundObj;
    
    //get the window and open it
    patWind = thePatch.wind;
    patWind.bringtofront();
}

function getPat2() {//DOES NOT WORK WHY?
    var thePatch, actualPatch, patWind;
    
    //get 'thePatch' object
    findObj.nameToFind = 'pat';
    thisPat.apply(findObj.findTheObj);
    thePatch = findObj.foundObj;
    
    //get the window and open it
    actualPatch = thePatch.patcher;
    patWind = actualPatch.wind;
    patWind.bringtofront();
}

Also here is the js for quick reference:

autowatch = 1;
inlets = 1;
outlets = 1;

var thisPat = this.patcher;
var findObj = {//object to handle location of an object in a patch
        nameToFind: undefined,
        foundObj: undefined,
        findTheObj: function (a) {
        if (a.varname === findObj.nameToFind) {
                findObj.foundObj = a;
            }
        }
    };

function getPat() {//DOES NOT WORK AS SUBPATCH DOESN'T HAVE WIND?
	var thePatch, patWind;
	
	//get 'thePatch' object
	findObj.nameToFind = 'pat';
	thisPat.apply(findObj.findTheObj);
	thePatch = findObj.foundObj;
	
	//get the window and open it
	patWind = thePatch.wind;
	patWind.bringtofront();
}

function getPat2() {//DOES NOT WORK WHY?
	var thePatch, actualPatch, patWind;
	
	//get 'thePatch' object
	findObj.nameToFind = 'pat';
	thisPat.apply(findObj.findTheObj);
	thePatch = findObj.foundObj;
	
	//get the window and open it
	actualPatch = thePatch.patcher;
	patWind = actualPatch.wind;
	patWind.bringtofront();
}

Try using the subpatcher() method of the Maxobj object, so actualPatch = thePatch.subpatcher()

And if you want to 'open' the subpatcher window, try patWind.visible = 1;

I've amended the js code with your suggestions and I am still not seeing the subpatchers window open.

I get the error message 'method getwind called on invalid object' and no open window.

When I use patWind.bringtofront(); I get no error message but still no window.

Thanks for the reply Ben.

Ok, I've taken a brief look at this again and there are some subtleties. If the window hasn't been opened before, it doesn't really work. What will work, however, is the 'front' message to the subpatcher patcher:

function getPat() {
    var thePatch, patWind;
    
    //get 'thePatch' object
    findObj.nameToFind = 'pat';
    thisPat.apply(findObj.findTheObj);
    thePatch = findObj.foundObj;
    //use the 'front' message to open the subpatcher window for the first time
    thePatch.message("front");
    patWind = thePatch.subpatcher().wind; //do other window-y things with the wind
    patWind.size = [300, 500];
}

function getPat() {
	var thePatch, patWind;
	
	//get 'thePatch' object
	findObj.nameToFind = 'pat';
	thisPat.apply(findObj.findTheObj);
	thePatch = findObj.foundObj;
	//use the 'front' message to open the subpatcher window for the first time
	thePatch.message("front");
	patWind = thePatch.subpatcher().wind; //do other window-y things with the wind
	patWind.size = [300, 500];
}

This method does work for me to open the window, but I still can't address the wind property. For example the 'patWind.size = [300, 500];' has no effect for me.

Also there is no effect if I try any of these:

    patWind.hasgrow = 0;
    patWind.hashorizscroll = 0;
    patWind.hasvertscroll = 0;
    patWind.hastitlebar = 0;
    patWind.location = [0, 0];

	patWind.location = [0, 0];


I'll do some more testing but this seems to be a good solution. Thanks again.

Having just said that if I do this:patWind.wind.size = [300, 500];
I do get the desired effect.

One last question. I was wondering if there is a reference of what messages can be sent like this to a patcher?

'front' seems to work as a message from js as does 'wclose' but sending these messages to the patch using a message box doesn't work.

Some of this is quasi-documented in the thispatcher help file. There are probably a handful of these kinds of messages that are not, unfortunately.

I would like to achieve something similar, I guess. I want to be able to resize a subpatch. The JS sits in the main patch.

var subpath = this.patcher.getnamed('subPatch');

I get an error: subPatch.wind is undefined.

I do this:
var subpath = this.patcher.getnamed('subPatch');
subPatch.wind.size = [300, 500];

a) "is undefined" in the error is telling you there is no variable named 

, because on the previous line you assign a variable named 

b) this.patcher.getnamed returns a Maxobj, not a Patcher object, so your object from (a) won't understand "wind.size" yet.

b) this.patcher.getnamed returns a Maxobj, not a Patcher object, so your object from (a) won't understand "wind.size" yet.
 

Thank you for your answer. This is working now:

var subPatch = this.patcher.getnamed('subPatch');

subPatch.subpatcher().wind.size = [300, 500];

Thank you for your answer. This is working now:
var subPatch = this.patcher.getnamed('subPatch');
subPatch.subpatcher().wind.size = [300, 500];

Can't address a subpatchers 'wind' in js?
