Hi, is there a callback mechanism for this so that it's possible to tell when windows have been resized, closes etc?

monitoring-whether-a-window-size-changes-in-js

// 11oLsen, report changed window size

outlets = 2;
var    nowsize;
var lastsize;

var pollTsk = new Task(getsize, this);

function on()
{
    lastsize = -1;

    pollTsk.interval = 10; //set interval of polling in ms 

    pollTsk.repeat();
}

function off()
{
    pollTsk.cancel();
}

function getsize()
{    

    nowsize = this.patcher.wind.size;
    if (nowsize[0] != lastsize[0] || nowsize[1] != lastsize[1]) {
        //post(lastsize);
        //post(nowsize);
        outlet(1,nowsize[1]);
        outlet(0,nowsize[0]);
        lastsize = nowsize;

    }

}

btw: there's a windowwatcher external in the sdk ready to compile, don't ask me why they don't add this to the standard object set..

I'm digging up this thread, I'm beginning with javascript and I'm not sure how I can get the all the coords of the window instead of the size only... Can you help me please ?

Thanks a lot 11olsen !

You use wind.rect instead of size. I can post an example when I'm home..

I have 2 questions if you don't mind answering them. It might sound stupid but this will probably help me understand better.


var pollTsk = new Task(getloc, this); 
// Where I can find documentation to know that's getloc I need to put here?..

function msg_int(s)
// What does this s correspond to ?

Thanks a lot !

Can you explain me why the values I get using "window getsize" message to a thispatcher object are different ?

Oh !  I actually have 3 questions :)

getloc is a reference to the function that's defined later in the file. Look at the Task object link in the above and it's examples.

In msg_int(s), the s is just the local variable name for the number (an integer). In this case it's getting either 1 or 0 from the toggle box outside the [js window_loc_watch.js]. FWIW I probably would've named that variable "enable_polling" or "polling_bool" or something like that to be more descriptive.

Thanks a lot Tyler, very clear, understood !

Do you know why I don't have the same values using "window getsize" message to [thispatcher] ?

"wind.location" includes the toolbars "window getsize" does not and reports x/y point of the bottom-right corner instead of height/width. You could probably build the same js around "this.patcher.getattr('rect')" which gives you the same coords like [thispatcher] but value 3 and 4 are height/width. You see there's a little inconsistency with the different methods to get window location in Max.

@ 11Olsen thanks for your sample code 10 years ago (!) and your recent update :)

Thanks guys ! You are real gifts for this community ;)
