jQuery UI Layout - How change a pane's options and dynamically apply them without toggling the pane open/closed?

Question

http://jsfiddle.net/jc3rj681/2/

Using the plugin jQuery UI Layout, I have several different panes. When the user resizes the window to a small size, I would like to call a function that changes the minsize and size of the pane so that I can make it smaller with the window.

I can do this, but for the changes to apply, I must toggle closed and then toggle open the pane. This creates a lot of flickering and ends up being pretty messy looking. I only need this one pane to resize in this fashion.

QUESTION: Is there a way I can apply these layout changes without having to toggle the pane twice for them to apply?

Check out this Fiddle that I made: http://jsfiddle.net/jc3rj681/2/

In here, the changes to the "width" of the show/hide button don't get applied until you toggle the pane. If you can make this width change work without toggling, I'm sure it would solve my problem as well.

$("#eastToggle").click(function () {

    testLayout.toggle('east');    
});


$("#attempt").click(function () {
    testLayout.options.east.spacing_closed = 20;
    testLayout.options.east.spacing_open = 20;
});

I'm not sure if there is a callback function or any special utility method that'll do the trick.

But you can try something like the following (probably with a resize function that'll resize the panes manually) -

var testLayout = $('body').layout({
  applyDefaultStyles: true,
  east: {
    spacing_closed: 100, //toggler width
    spacing_open: 100,
    togglerLength_closed: 200, //toggler height (length)
    togglerLength_open: 200
  }
});

$("#eastToggle").click(function() {

  testLayout.toggle('east');

});


$("#attempt").click(function() {
  resize('east', 20);
});


// A function to resize the tab
function resize(region, space) {
  // Width of the new center pane
  var newCenterWidth = parseInt($('body .ui-layout-center').css('width').split('px')[0]) + testLayout.options.east.spacing_closed - space;

  // Change the options so they don't affect the layout when you expand / collapse again
  testLayout.options.east.spacing_closed = space;
  testLayout.options.east.spacing_open = space;

  // Manually resize the panes
  $('body .ui-layout-resizer-' + region).css('width', space);
  $('body .ui-layout-center').css('width', newCenterWidth);
}
