AlignmentRef
public struct AlignmentRef : AlignmentProtocol, GWeakCapturing
The GtkAlignment
widget controls the alignment and size of its child widget.
It has four settings: xscale, yscale, xalign, and yalign.
The scale settings are used to specify how much the child widget should
expand to fill the space allocated to the GtkAlignment
.
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 are used to 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.
GtkAlignment has been deprecated in 3.14 and should not be used in
newly-written code. The desired effect can be achieved by using the
GtkWidget:halign
, GtkWidget:valign
and GtkWidget:margin
properties on the
child widget.
The AlignmentRef
type acts as a lightweight Swift reference to an underlying GtkAlignment
instance.
It exposes methods that can operate on this data type through AlignmentProtocol
conformance.
Use AlignmentRef
only as an unowned
reference to an existing GtkAlignment
instance.

Untyped pointer to the underlying `GtkAlignment` instance.

property instead.Declaration
