Failed to pass keypress/release event to nw app

[yilang2007lw]

I use node-x11 to grab keyboard for a screensaver node-webkit app.I grabbed the keyboard and mouse event succeed, but only pointer events can delivery to my html input widget, the keypress/release not.

Below is my code:

        function grab_window(wid) {
            console.log("-----------grab window----------------");
            console.log(wid);
            var x11 = require('x11');
            x11.createClient(function(err, display) {
                var X = display.client;
                X.ChangeWindowAttributes(wid, { eventMask: x11.eventMask.ResizeRedirect|x11.eventMask.KeyPress|x11.eventMask.KeyRelease|x11.eventMask.StructureNotify|x11.eventMask.SubstructureNotify});
                X.LowerWindow(wid);
                X.GrabKeyboard(wid, false, 0, 1, 1);
                X.on('event', function(ev) {
                    console.log(ev.name);
                });
            });
        };

        var gui = require('nw.gui');
        var win = gui.Window.get();
        win.title = "cscreensaver";
        //win.enterKioskMode();
        onload = function () {
            win.setAlwaysOnTop(true);
            win.setShowInTaskbar(false);
            var child_process = require('child_process');
            var cmd = "xwininfo -name 'cscreensaver' -int |grep 'cscreensaver' | awk '{print $4}'";
            var wid = 0;
            child_process.exec(cmd, function(err, stdout, stderr) {
                wid = parseInt(stdout);
                win.show();
                grab_window(wid);
            });
        };

//code end

The '"console.log(ev.name);" can print the key event when I press my keyboard, but it can't go into my html input, how to solve this, thanks for any reply.
