How to set the _NET_WM_WINDOW_TYPE property?

[IonicaBizau]

Here is a related question–maybe some of you have better ideas.

In the meantime I want to try setting the _NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_DESKTOP property, having the window id. How can I do that?

have you looked at https://github.com/santigimeno/node-ewmh ?

@sidorares Nope! Looking at it. Is there any example on setting such properties?

ChangeProperty example - https://github.com/sidorares/node-x11/blob/master/examples/smoketest/changeprop.js#L16

You'll need to do InternAtom to get id for _NET_WM_WINDOW_TYPE and _NET_WM_WINDOW_TYPE_DESKTOP, example - https://github.com/sidorares/node-x11/blob/master/examples/smoketest/atoms.js#L5

Oh, there are some nice helpers in https://github.com/santigimeno/node-x11-prop as well

InternAtom(true, "_SET_WM_WINDOW_TYPE", function (err, atomId) { 
   /* ... */
});

The atomId is 0–is it fine?

Hmm, here is what I did:

var x11 = require('x11');

var PointerMotion = x11.eventMask.PointerMotion;
x11.createClient(function(err, display) {
    var X = display.client;
    var root = display.screen[0].root;

    // mode: 0 replace, 1 prepend, 2 append
    // mode, wid, name, type, format, data
    X.InternAtom(true, "_NET_WM_WINDOW_TYPE", function (err, atomId) { // 332
        X.InternAtom(true, "_NET_WM_WINDOW_TYPE_DESKTOP", function (err, desktop) { // 337
debugger
            X.ChangeProperty(0, Number(process.argv[2]), atomId, X.atoms.ATOM, 8, desktop);
        });
    });
});

I don't know what's wrong, but the window doesn't become most bottom.... 😢

what window manager are you using?
