void
gtk_aspect_frame_set (
  GtkAspectFrame* aspect_frame,
  gfloat xalign,
  gfloat yalign,
  gfloat ratio,
  gboolean obey_child
)

Set parameters for an existing GtkAspectFrame.

`xalign`	`gfloat`
	Horizontal alignment of the child within the allocation of the `GtkAspectFrame`. This ranges from 0.0 (left aligned) to 1.0 (right aligned)
`yalign`	`gfloat`
	Vertical alignment of the child within the allocation of the `GtkAspectFrame`. This ranges from 0.0 (top aligned) to 1.0 (bottom aligned)
`ratio`	`gfloat`
	The desired aspect ratio.
`obey_child`	`gboolean`
	If `TRUE`, `ratio` is ignored, and the aspect ratio is taken from the requistion of the child.
