Struct gtk4::IMContextSimple

source ·
pub struct IMContextSimple { /* private fields */ }
Expand description

IMContextSimple is an input method supporting table-based input methods.

§Compose sequences

IMContextSimple 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, IMContextSimple 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

IMContextSimple also supports numeric entry of Unicode characters by typing Ctrl-Shift-u, followed by a hexadecimal Unicode codepoint.

For example,

Ctrl-Shift-u 1 2 3 Enter

yields U+0123 LATIN SMALL LETTER G WITH CEDILLA, i.e. ģ.

§Dead keys

IMContextSimple supports dead keys. For example, typing

dead_acute a

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