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.
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.
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.
gtkFixed is the equivalent of
