Introduction and Rationale

The 'toolbar' namespace will provide Jetpack developers the ability to modify toolbars in chrome space in the browser.

Proposal

Create an easy way to get a handle on the navigation toolbar, the bookmarks toolbar. Provide an elegant API to add, modify and remove items for each bar, as well as hiding and showing the toolbars.

// get an abstracted "jetpacky" nav bar object / bookmarks bar object
var navBar = jetpack.toolbar.navigation();

// return the array of 'toolbarbutton' objects
navBar.children();

// remove the 3rd child:
navBar.children()[2].remove();

// get a button labeled 'my button'
var btn = navBar.find({label:"my button"});

// replace the function bound to the button
btn.click = function ClickerFunk(){ alert("I clicked my button");};

// number of toolbar buttons: acts like an array
navBar.length;

// make a button
var button = {
    // 'self' would refer to the button
    // 'self.toolbar' would refer to the parentNode
    id: 73, // or "foobutton"
    label: "my button", 
    imageDefault: "http://mybutton.com/image.png",
    imageAlternate: "http://mybutton.com/imageAlt.png",
    click: function(){self.image(self.imageAlternate);},
    mouseover: function(){jetpack.audio.play(self.customAttribute);},
    customAttribute: "http://mybutton.com/yelling.ogg"
};

// change the image displayed
button.image("http://foobar.com/foopy.png");

// move the button
button.moveRight(); // move to the right 1 slot

button.moveLeft(3); // move to the left 3 slots

// .append() and .prepend():

//append button to the end of the toolbar
navBar.append(button);

// prepend button to the beginning of the toolbar
navBar.prepend(button);

// find a button by label or other string or number attribute
var anotherButton = navBar.find({label:'their button'});

// append button to toolbar after 'anotherButton'
navbar.append(button, anotherButton);

// find and append after the button labeled "their button"
navbar.append(button, 'their button');

// get the bookmarks toolbar
var bookmarksBar = jetpack.toolbar.bookmarks();

//make a bookmark button
var bookmarkButton = {label: "GrouchoMarx.com", 
		      url:"http://grouchomarx.com/",
		      image: "http://groucho.com/image.png",
                      type: 'bookmark' // the default
}

// bookmark and feed buttons use the same methods to attach, move, find vis a vis the toolbar 

var feedButton = { label: "my RSS feed",
		   image: "http://myfeed.com/feed.png",
		   url: "http://www.rssfeed.com/rss.xml",
		   type: "feed"
};
