public class Fixed extends Container
You should not use Fixed for any non-trivial purpose. While you might think at first that it would simplify your application, the reality is that Fixed is almost always the wrong Container choice. Because GTK is the widget toolkit used to power the user interfaces of GNOME applications, the appearance of Widgets is very dynamic. Different window managers and theme engines can radically change the size and appearance of Widgets to suit varying accessibility and usability requirements; different fonts available to your users will cause Labels to be sized differently than you'd expect, and of course translation completely throws predictability right out the window. Since the Fixed Container does not adapt to the size requests of the Widgets with in it, the frequent result is truncated text, overlapping Widgets, and other visual bugs.
The Fixed widget can't be properly mirrored in right-to-left languages such as Hebrew and Arabic. A Fixed widget with a right-to-left font will render your application unusable.
Adding or removing any GUI elements from this Fixed requires you to reposition all the other Widgets within it. As you can imagine, this will end up a long-term maintenance headache for your application.
If any of those are a concern for your application, then you should be
using a different Container, either combinations of VBox and
HBox, or perhaps Table. You have been warned!

Calling move() will cause GTK to inherently redraw the
entire Fixed surface. If you have many Widgets in a Fixed, this can
lead to flickering. Consider using Layout or
DrawingArea instead.
The x and y co-ordinates are measured in pixels from the top left corner of the Fixed.

It is up to you to ensure that the placing of the new Widget will not overlap any existing Widgets. If this is starting to be a burden, it's a good sign you're using the wrong Container!
