Detailed Description

A widget which controls the alignment and size of its child.

Normally, a widget is allocated at least as much size as it requests, and, most widgets expand to fill any extra allocated space, but sometimes this behavior is not desired. The alignment widget allows the programmer to specify how a widget should expand and position itself to fill the area it is allocated.

It has four settings: xscale, yscale, xalign, and yalign: The scale settings 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 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.

Gtk::Alignment::Alignment ( float    xalign = 0.5,
float    yalign = 0.5,
float    xscale = 1.0,
float    yscale = 1.0
[explicit]
 

Constructor to create an Alignment object.

Parameters:
xalign  The initial horizontal alignment of the child.
yalign  The initial vertical alignment of the child.
xscale  The initial amount that the child expands horizontally to fill up unused space.
yscale  The initial amount that the child expands vertically to fill up unused space.

Gtk::Alignment::Alignment ( AlignmentEnum    xalign,
AlignmentEnum    yalign = Gtk::ALIGN_CENTER,
float    xscale = 1.0,
float    yscale = 1.0
[explicit]
 

Constructor to create an Alignment object.

Parameters:
xalign  A Gtk::AlignmentEnum describing the initial horizontal alignment of the child.
yalign  A Gtk::AlignmentEnum describing the initial vertical alignment of the child.
xscale  The initial amount that the child expands horizontally to fill up unused space.
yscale  The initial amount that the child expands vertically to fill up unused space.

void Gtk::Alignment::set ( AlignmentEnum    xalign,
AlignmentEnum    yalign = Gtk::ALIGN_CENTER,
float    xscale = 1.0,
float    yscale = 1.0
 

Sets the Alignment values.

Parameters:
xalign  The horizontal alignment of the child of this Alignment, from 0 (left) to 1 (right).
yalign  The vertical alignment of the child of this Alignment, from 0 (top) to 1 (bottom).
xscale  The amount that the child 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 the space allocated for the 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 .

void Gtk::Alignment::set ( float    xalign = 0.5,
float    yalign = 0.5,
float    xscale = 1.0,
float    yscale = 1.0
 

Sets the Alignment values.

Parameters:
xalign  The horizontal alignment of the child of this Alignment, from 0 (left) to 1 (right).
yalign  The vertical alignment of the child of this Alignment, from 0 (top) to 1 (bottom).
xscale  The amount that the child 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 the space allocated for the 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 .
