Package: Alignment

Description

package Gtk.Alignment is

A Gtk_Alignment controls the size and alignment of its single child inside the area allocated to the alignment widget.

The scale/size settings indicate how much the child will expand to fill the container. The values should be in the range 0.0 (no expansion) to 1.0 (full expansion). Note that the scale only indicates the minimal size for the child, it does not force an absolute size.

The alignment settings indicate where in the alignment widget the child should be located. The values are in the range 0.0 (top or left) to 1.0 (bottom or right). These settings are irrelevant if the child is fully expanded.

Binding from C File version 2.8.17
