Add body class even when tray is closed.

If you need to know when the height of the navbar changes, you can key your JavaScript off an event rather than the presence of a class. Here's some stub code.

jQuery(document).bind('offsettopchange', function (e) {
  var offset = jQuery('[data-offset-top]').data('offset-top');
  // Do something with the top offset....
});

I'm tentatively closing this issue...

If you update your module you will see a new class="navbar-tray-open" added to body. It also updates the padding on the body for open and closed status.

Sorry, I misread your question. I thought you were asking for a class notification for open instead of closed. I've reopened in that case.

I do see what you mean. What I didn't notice I was doing is leaving the core toolbar installed and it has a setting to offset the top padding. Since it hides behind this navbar, I never could see it, but was still getting the benefit of the top offset when the navbar-tray was closed. Of course, no one wants two toolbars sitting on top of one another, so that functionality should be introduced into this module so it can be a *true* replacement for the core toolbar.

I've spent a lot of time on this module today trying to figure out other bugs, so I will keep this in mind and if I figure it out I will report back.

[edit] I updated the example function. The previous one was old :)

This allows for themes to make the necessary CSS adjustments for other elements that may have position: fixed; top: 0; CSS. I think a CSS class on the body tag would be a simpler way to support this, rather than requiring the theme to always check if the navbar exists with JavaScript.

The navbar cannot be guaranteed to have a fixed height. Text sizes change and other modules can add content to it and change it's dimensions potentially.

I really encourage you to use the following function (or something like it) to determine the size of the navbar.

$(document)
  .on('drupalViewportOffsetChange', function (event, offsets) {
    /* Do stuff */
  });

Simply knowing that the navbar is on the page will not let you know its dimensions with certainty.

That warning given, I've added a navbar-administration class to the body tag in 7.x-1.x. I suggest you don't use it :)
