The alignment widget allows you to place a widget within its window at a position and size relative to the size of the Alignment widget itself. For example, it can be very useful for centering a widget within the window.
There are only two methods associated with the Alignment widget:
Gtk::Alignment.new( xalign, yalign, xscale, yscale ) Gtk::Alignment#set( xalign, yalign, xscale, yscale )
The first method creates a new Alignment widget with the specified parameters. The second method allows the alignment parameters of an exisiting Alignment widget to be altered.
All four alignment parameters are floating point numbers which can range from 0.0 to 1.0. The xalign and yalign arguments affect the position of the widget placed within the Alignment widget. The xscale and yscale arguments effect the amount of space allocated to the widget.
For an example of using an Alignment widget, refer to the example for the Progress Bar widget.
