i am trying to access he mouse position in absolute screen coordinates from within a jsui object. The wind.location property returns the coordinates of the mouse cursor relative to the Left Top of the main Max/MSP application window, not the screen coordinates. The reason i need the absolute screen coordinates is that i want to lock the mouse position while drugging inside the jsui.

I also faced the same challenge, and for now I'm using mousestate (obviously outside the JSUI). But a solution within the JSUI would be more convenient.

Try adding the [jsui] click co-ordinates to the object box offset to the patcher window offset as illustrated below. It will output the cursor position like [mousestate] in global mode ("0"). I hope it helps.

var patchpos = this.patcher.wind.location;

function onclick(x,y)
{
    var patchpos = this.patcher.wind.location;
    var objpos = this.box.rect;
    var absx = patchpos[0]+objpos[0]+x;
    var absy = patchpos[1]+objpos[1]+y;
    outlet(0, absx, absy);
}

it works, thanks !!!
I love max forum :-)
