### Interfaces

GtkFixed implements AtkImplementorIface and `GtkBuildable`.

### Detailed Description

The `GtkFixed` widget is a container which can place child widgets at fixed positions and with fixed sizes, given in pixels. `GtkFixed` performs no automatic layout management.

For most applications, you should not use this container! It keeps you from having to learn about the other GTK+ containers, but it results in broken applications. With `GtkFixed`, the following things will result in truncated text, overlapping widgets, and other display bugs:

- Themes, which may change widget sizes.

- Fonts other than the one you used to write the app will of course change the size of widgets containing text; keep in mind that users may use a larger font because of difficulty reading the default, or they may be using Windows or the framebuffer port of GTK+, where different fonts are available.

- Translation of text into other languages changes its size. Also, display of non-English text will use a different font in many cases.

In addition, the fixed widget can't properly be mirrored in right-to-left languages such as Hebrew and Arabic. i.e. normally GTK+ will flip the interface to put labels to the right of the thing they label, but it can't do that with `GtkFixed`. So your application will not be usable in right-to-left languages.

Finally, fixed positioning makes it kind of annoying to add/remove GUI elements, since you have to reposition all the other elements. This is a long-term maintenance problem for your application.

If you know none of these things are an issue for your application, and prefer the simplicity of `GtkFixed`, by all means use the widget. But you should be aware of the tradeoffs.

### Structures

`GtkFixed`

  The `GtkFixed` struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)

  `list` *children; | a list of `GtkFixedChild` elements, containing the child widgets and their positions.

### Convenient Construction

`gtkFixed` is the equivalent of `gtkFixedNew`.
