Implemented Interfaces

GtkAlignment implements AtkImplementorIface and GtkBuildable.

Includes

#include <gtk/gtk.h>

Description

The GtkAlignment 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 GtkAlignment. 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.

Functions

gtk_alignment_new ()

GtkWidget *
gtk_alignment_new (gfloat xalign,
                   gfloat yalign,
                   gfloat xscale,
                   gfloat yscale);

Creates a new GtkAlignment.

Parameters

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 GtkAlignment.

 

yscale

the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to xscale .

 

Returns

the new GtkAlignment.


gtk_alignment_set ()

void
gtk_alignment_set (GtkAlignment *alignment,
                   gfloat xalign,
                   gfloat yalign,
                   gfloat xscale,
                   gfloat yscale);

Sets the GtkAlignment values.

Parameters

alignment

a GtkAlignment.

 

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 GtkAlignment.

 

yscale

the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to xscale .

 

gtk_alignment_get_padding ()

void
gtk_alignment_get_padding (GtkAlignment *alignment,
                           guint *padding_top,
                           guint *padding_bottom,
                           guint *padding_left,
                           guint *padding_right);

Gets the padding on the different sides of the widget. See gtk_alignment_set_padding().

Parameters

alignment

a GtkAlignment

 

padding_top

location to store the padding for the top of the widget, or NULL.

[out][allow-none]

padding_bottom

location to store the padding for the bottom of the widget, or NULL.

[out][allow-none]

padding_left

location to store the padding for the left of the widget, or NULL.

[out][allow-none]

padding_right

location to store the padding for the right of the widget, or NULL.

[out][allow-none]

gtk_alignment_set_padding ()

void
gtk_alignment_set_padding (GtkAlignment *alignment,
                           guint padding_top,
                           guint padding_bottom,
                           guint padding_left,
                           guint padding_right);

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.

Parameters

alignment

a GtkAlignment

 

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.
