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.
GtkWidget * gtk_alignment_new (gfloat xalign,gfloat yalign,gfloat xscale,gfloat yscale);
Creates a new GtkAlignment.
|
the horizontal alignment of the child widget, from 0 (left) to 1 (right). |
|
the vertical alignment of the child widget, from 0 (top) to 1 (bottom). |
|
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. |
|
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. |
void gtk_alignment_set (GtkAlignment *alignment,gfloat xalign,gfloat yalign,gfloat xscale,gfloat yscale);
Sets the GtkAlignment values.

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().

Since 2.4
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.
