All Implemented Interfaces:

PointerInterface

public class AspectFrame
extends Widget

`GtkAspectFrame` preserves the aspect ratio of its child.

The frame can respect the aspect ratio of the child widget,
or use its own aspect ratio.

# CSS nodes

`GtkAspectFrame` uses a CSS node with name `frame`.

Constructor Details

AspectFrame

public AspectFrame(PointerContainer pointer)

AspectFrame

public AspectFrame(float xalign,
 float yalign,
 float ratio,
 boolean obey_child)

Create a new `GtkAspectFrame`.

Parameters:

xalign - Horizontal alignment of the child within the parent. Ranges from 0.0 (left aligned) to 1.0 (right aligned)

yalign - Vertical alignment of the child within the parent. Ranges from 0.0 (top aligned) to 1.0 (bottom 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.
