The Gtk.Alignment.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.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.
GtkAlignment has been deprecated in 3.14 and should not be used in newly-written code. The desired effect can be achieved by using the Gtk.Widget.Gtk_Widget:halign, Gtk.Widget.Gtk_Widget:valign and Gtk.Widget.Gtk_Widget:margin properties on the child widget.

The padding to insert at the top of the widget.
Xalign_Property : constant Glib.Properties.Property_Float;
Horizontal position of child in available space. A value of 0.0 will flush the child left (or right, in RTL locales); a value of 1.0 will flush the child right (or left, in RTL locales).
Xscale_Property : constant Glib.Properties.Property_Float;
If available horizontal space is bigger than needed, how much of it to use for the child. A value of 0.0 means none; a value of 1.0 means all.

Vertical position of child in available space. A value of 0.0 will flush the child to the top; a value of 1.0 will flush the child to the bottom.
Yscale_Property : constant Glib.Properties.Property_Float;
If available vertical space is bigger than needed, how much of it to use for the child. A value of 0.0 means none; a value of 1.0 means all.
