Package: Alignment

- Goto spec source

# Description

    package Gtk.Alignment is

A Gtk_Alignment controls the size and alignment of its single child inside the area allocated to the alignment widget.

The scale/size settings indicate how much the child will expand to fill the container. The values should be in the range 0.0 (no expansion) to 1.0 (full expansion). Note that the scale only indicates the minimal size for the child, it does not force an absolute size.

The alignment settings indicate where in the alignment widget the child should be located. The values are in the range 0.0 (top or left) to 1.0 (bottom or right). These settings are irrelevant if the child is fully expanded.

### Gtk_New

- Goto spec in source

    procedure Gtk_New (Alignment: out Gtk_Alignment;Xalign: Gfloat;Yalign: Gfloat;Xscale: Gfloat;Yscale: Gfloat);

### Initialize

- Goto spec in source

    procedure Initialize (Alignment: access Gtk_Alignment_Record'Class;Xalign: Gfloat;Yalign: Gfloat;Xscale: Gfloat;Yscale: Gfloat);

Creates a new Gtk.Alignment.Gtk_Alignment. "xalign": the horizontal alignment of the child widget, from 0 (left) to 1 (right). "yalign": the vertical alignment of the child widget, from 0 (top) to 1 (bottom). "xscale": the amount that the child widget expands horizontally to fill up unused space, from 0 to 1. A value of 0 indicates that the child widget should never expand. A value of 1 indicates that the child widget will expand to fill all of the space allocated for the Gtk.Alignment.Gtk_Alignment. "yscale": the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to Xscale.

### Get_Type

- Goto spec in source
- Goto body in source

    function Get_Type return Glib.GType;

### Get_Padding

- Goto spec in source

    procedure Get_Padding (Alignment: access Gtk_Alignment_Record;Padding_Top: out Guint;Padding_Bottom: out Guint;Padding_Left: out Guint;Padding_Right: out Guint);

### Set_Padding

- Goto spec in source

    procedure Set_Padding (Alignment: access Gtk_Alignment_Record;Padding_Top: Guint;Padding_Bottom: Guint;Padding_Left: Guint;Padding_Right: Guint);

Sets the padding on the different sides of the widget. The padding adds blank space to the sides of the widget. For instance, this can be used to indent the child widget towards the right by adding padding on the left. Since: gtk+ 2.4 "padding_top": the padding at the top of the widget "padding_bottom": the padding at the bottom of the widget "padding_left": the padding at the left of the widget "padding_right": the padding at the right of the widget.

### Set

- Goto spec in source

    procedure Set (Alignment: access Gtk_Alignment_Record;Xalign: Gfloat;Yalign: Gfloat;Xscale: Gfloat;Yscale: Gfloat);

Sets the Gtk.Alignment.Gtk_Alignment values. "xalign": the horizontal alignment of the child widget, from 0 (left) to 1 (right). "yalign": the vertical alignment of the child widget, from 0 (top) to 1 (bottom). "xscale": the amount that the child widget expands horizontally to fill up unused space, from 0 to 1. A value of 0 indicates that the child widget should never expand. A value of 1 indicates that the child widget will expand to fill all of the space allocated for the Gtk.Alignment.Gtk_Alignment. "yscale": the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to Xscale.
