Child window position limit (constrained) as default behavior

[aswzen]

i saw this 3 years old question
http://www.jeasyui.com/forum/index.php?topic=603.0
about How to limit draggable/window movement

but i see this problem solution still not implemented as default behavior of easyui window if the properti inline:true
see this fiddle: http://jsfiddle.net/hocu4Lwp/2/



can you make this as default behavior?

thank you in advance

The extended method 'constrain' method can be used to prevent the window from moving out of its parent container.

Code:

$.extend($.fn.window.methods, {
	constrain: function(jq){
		return jq.each(function(){
			var target = this;
			var state = $(target).data('window');
			$(target).window('window').draggable({
				onDrag: function(e){
					var d = e.data;
					if (d.left < 0){d.left = 0;}
					if (d.top < 0){d.top = 0;}
					var parent = state.options.inline ? $(d.parent) : $(window);
					if (d.left + $(d.target).outerWidth() > parent.width()){
						d.left = parent.width() - $(d.target).outerWidth();
					}
					if (d.top + $(d.target).outerHeight() > parent.height()){
						d.top = parent.height() - $(d.target).outerHeight();
					}

					state.proxy.css({
						display:'block',
						left: e.data.left,
						top: e.data.top
					});

					return false;
				}
			})
		})
	}
})

It's for window only not applied to dialog isn't it ?
I replace the window to dialog and it works good.

Code:

$.extend($.fn.dialog.methods, {
    constrain: function (jq) {
        return jq.each(function () {
            var target = this;
            var state = $(target).data('window');
            $(target).dialog('dialog').draggable({
