GtkAspectFrame
A frame that constrains its child to a particular aspect ratio.
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.
@frame:
@xalign:
@yalign:
@ratio:
@obey_child:
@center_allocation:
Create a new #GtkAspectFrame.
@label: Label text.
@xalign: Horizontal lignment of the child within the allocation of
the #GtkAspectFrame. This ranges from 0.0 (left aligned)
to 1.0 (right aligned)
@yalign: Vertical lignment 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.
@ratio: The desired aspect ratio.
Set parameters for an existing #GtkAspectFrame.
@aspect_frame: a #GtkAspectFrame
@xalign: Horizontal lignment of the child within the allocation of
the #GtkAspectFrame. This ranges from 0.0 (left aligned)
to 1.0 (right aligned)
@yalign: Vertical lignment 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.
