The gtk:im-context-simple class is a simple input method context supporting table-based input methods.

Compose sequences

The gtk:im-context-simple class reads compose sequences from the first of the following files that is found: ~/.config/gtk-4.0/Compose, ~/.XCompose, /usr/share/X11/locale/$locale/Compose (for locales that have a nontrivial Compose file). A subset of the file syntax described in the Compose(5) manual page is supported. Additionally, include "L" loads GTK’s built-in table of compose sequences rather than the locale-specific one from X11.

If none of these files is found, the gtk:im-context-simple class uses a built-in table of compose sequences that is derived from the X11 Compose files.

Note that compose sequences typically start with the Compose_key, which is often not available as a dedicated key on keyboards. Keyboard layouts may map this keysym to other keys, such as the right Control key.

Unicode characters

The gtk:im-context-simple class also supports numeric entry of Unicode characters by typing the Ctrl-Shift-u key, followed by a hexadecimal Unicode codepoint. For example, Ctrl-Shift-u 1 2 3 Enter yields U+0123 LATIN SMALL LETTER G WITH CEDILLA, that is the ģ character.

Dead keys

The gtk:im-context-simple class supports dead keys. For example, typing

dead_acute a  

yields U+00E! LATIN SMALL LETTER_A WITH ACUTE, that is the á character. Note that this depends on the keyboard layout including dead keys.
