Programmatically slide out a collapsed region

[bitdifferent]

How can I programmatically slide out a collapsed region, without expanding it? I'm talking about the same behaviour that occurs when you click the collapsed representation of the region - the temporary slide out? I've tried lots of things but without success so far.

slideOut


layout.getRegion('west').slideOut();


slideIn


layout.getRegion('west').slideIn();
