Gtk.Alignment

const Gtk = imports.gi.Gtk;

let alignment = new Gtk.Alignment({
    bottom_padding: value,
    left_padding: value,
    right_padding: value,
    top_padding: value,
    xalign: value,
    xscale: value,
    yalign: value,
    yscale: value,
});
  

The Gtk.Alignment widget controls the alignment and size of its child widget. It has four settings: xscale, yscale, xalign, and yalign.

The scale settings are used to specify how much the child widget should expand to fill the space allocated to the Gtk.Alignment. The values can range from 0 (meaning the child doesn't expand at all) to 1 (meaning the child expands to fill all of the available space).

The align settings are used to place the child widget within the available area. The values range from 0 (top or left) to 1 (bottom or right). Of course, if the scale settings are both set to 1, the alignment settings have no effect.

<note> <para> Note that the desired effect can in most cases be achieved by using the Gtk.halign, Gtk.valign and Gtk.margin properties on the child widget, so Gtk.Alignment should not be used in new code. </para> </note>
