This GTK+ version 2.12.3. GTK+ is a multi-platform toolkit for creating graphical user interfaces.

<!-- ##### SECTION Title ##### -->
GtkAspectFrame

<!-- ##### SECTION Short_Description ##### -->
A frame that constrains its child to a particular aspect ratio

<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkAspectFrame is useful when you want
pack a widget so that it can resize but always retains
the same aspect ratio. For instance, one might be
drawing a small preview of a larger image. #GtkAspectFrame
derives from #GtkFrame, so it can draw a label and
a frame around the child. The frame will be
"shrink-wrapped" to the size of the child.

<!-- ##### FUNCTION gtk_aspect_frame_new ##### -->

Create a new #GtkAspectFrame.
</para>

@label: Label text.
@xalign: Horizontal alignment of the child within the allocation of
the #GtkAspectFrame. This ranges from 0.0 (left aligned)
to 1.0 (right aligned)
@yalign: Vertical alignment of the child within the allocation of
the #GtkAspectFrame. This ranges from 0.0 (left aligned)
to 1.0 (right aligned)
@ratio: The desired aspect ratio.
@obey_child: If %TRUE, @ratio is ignored, and the aspect
    ratio is taken from the requistion of the child.
@Returns: the new #GtkAspectFrame.
<!-- # Unused Parameters # -->
@ratio: The desired aspect ratio.


<!-- ##### FUNCTION gtk_aspect_frame_set ##### -->
<para>
Set parameters for an existing #GtkAspectFrame.

@aspect_frame: a #GtkAspectFrame
@xalign: Horizontal alignment of the child within the allocation of
the #GtkAspectFrame. This ranges from 0.0 (left aligned)
to 1.0 (right aligned)
@yalign: Vertical alignment of the child within the allocation of
the #GtkAspectFrame. This ranges from 0.0 (left aligned)
to 1.0 (right aligned)
@ratio: The desired aspect ratio.
@obey_child: If %TRUE, @ratio is ignored, and the aspect
    ratio is taken from the requistion of the child.
