# example

Core requsests usage:

    var x11 = require('../lib/x11');

    var xclient = x11.createClient();
    var Exposure = x11.eventMask.Exposure;
    var PointerMotion = x11.eventMask.PointerMotion;

    xclient.on('connect', function(display) {
        var X = this;
        var root = display.screen[0].root;
        var white = display.screen[0].white_pixel;
        var black = display.screen[0].black_pixel;

        var wid = X.AllocID();
        X.CreateWindow(
           wid, root, 
           0, 0, 100, 100, 
           1, 1, 0,
           { 
               backgroundPixel: white, eventMask: Exposure|PointerMotion  
           }
        );
        X.MapWindow(wid);
      
        var gc = X.AllocID();
        X.CreateGC(gc, wid, { foreground: black, background: white } );

        X.on('event', function(ev) {
            if (ev.type == 12)
            {
                X.PolyText8(wid, gc, 50, 50, ['Hello, Node.JS!']); 
            } 
        });
        X.on('error', function(e) {
            console.log(e);
        });
    });


Simple core requests Window wrapper:

    var x11 = require('x11');
    var Window = require('./wndwrap');
    var xclient = x11.createClient();
    xclient.on('connect', function(display) {
        var mainwnd = new Window(xclient, 0, 0, 100, 100);
        mainwnd.on('expose', function(ev) {        
            ev.gc.drawText(50, 50, 'Hello, NodeJS!');
        });
        mainwnd.map();
    });
