app object

This page shows examples of the current app object API. First we show how to open a window:

var window = app.createWindow({
   width  : 1024,
   height : 768,
   icons  : __dirname + '/content/icons', //used for application window icon
   showChrome : false,                    //display as standard os window with max/min/close buttons
   alpha: true,
   autoResize: false,            //adjust window size automatically according to content.
   resizable: true,              //allow user resize of window
   margin: 0,
   disableSecurity:true,         //turn off security restrictions.
   showResizeGrip:false,         //show/hide the resize grip.
   name:'test',                  //undocumented parameter
   left:-1,
   top:-1,
   opacity:1,
   fullscreen:false,
   topmost:false,
   
   /***************************** defaults ********************************
   * url            : 'http://appjs', // serve static file root and routers
   * autoResize     : false,          // resizes in response to html content
   * showChrome     : true,           // show border and title bar
   * resizable      : false,          // control if users can resize window
   * disableSecurity: true,           // allow cross origin requests
   * opacity        : 1,              // flat percent opacity for window
   * alpha          : false,          // per-pixel alpha blended (Win & Mac)
   * fullscreen     : false,          // client area covers whole screen
   * left           : -1,             // centered by default
   * top            : -1,             // centered by default

});

Following code gives an example of creating a native menu. Use & to create a shortcut key, so &File will cause Alt+F to select the File menu item on windows, other OS use the appropriate key plus the letter after the & to select it:

var menubar = app.createMenu([{
   label:'&File',
   submenu:[
    {
       label:'E&xit',
       action: function(){
       window.close();
     }
 }
 ]
 },{
    label:'&Window',
  submenu:[
    {
      label:'Fullscreen',
      action:function(item) {
        window.frame.fullscreen();
        console.log(item.label+" called.");
      }
    },
    {
      label:'Minimize',
      action:function(){
        window.frame.minimize();
      }
    },
    {
      label:'Maximize',
      action:function(){
        window.frame.maximize();
      }
    },{
      label:''//separator
    },{
      label:'Restore',
      action:function(){
        window.frame.restore();
      }
    }
  ]
}]);

menubar.on('select',function(item){
  console.log("menu item "+item.label+" clicked");
});

// don't forget to attach it to the window!

var window = app.createWindow({
  width  : 640,
  height : 460,
  icons  : __dirname + '/content/icons'
});

window.on('create', function(){
  console.log("Window Created");
  window.frame.show();
  window.frame.center();
  window.frame.setMenuBar(menubar); // attaching menubar to a new window.
});

Create a tray menu to be displayed in the status bar:

var trayMenu = app.createMenu([{
  label:'Show',
  action:function(){
    window.frame.show();
  },
},{
  label:'Minimize',
  action:function(){
    window.frame.hide();
  }
},{
  label:'Exit',
  action:function(){
    window.close();
  }
}]);

Display a status icon and attach the trayMenu to it.

var statusIcon = app.createStatusIcon({
  icon:'./data/content/icons/32.png',
  tooltip:'AppJS Hello World',
  menu:trayMenu
});
