We have three places where layout information is stored:
1. In the widget itself. The widget has e.g. "margin", "padding" or
"alignX/Y". These properties can be used by the layouts:
button.setAlignX("center");
2. In the layout instance used. This is what you have found in the API
docs. The "alignX" property in the HBox will align all children:
hbox.setAlignX("center");
3. In the layout properties declared while adding a widget to its
parent. Any layout information specific to a widget/layout combination
is stored here. The grid uses this to define the widget's cell:
parent.add(child, {row: 1, column: 3});

In your case you can either configure the HBox to render all children
centered (option 2) or set the alignment just for the "filter bar"
(this._filterBar.setAlign("center"))
