IMContextSimple
Object Hierarchy:
Description:
`GtkIMContextSimple` is an input method supporting table-based input methods.
Compose sequences
`GtkIMContextSimple` 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, `GtkIMContextSimple` 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
`GtkIMContextSimple` also supports numeric entry of Unicode characters by typing <kbd>Ctrl</kbd>-<kbd>Shift</kbd>-< kbd>u</kbd>, 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
`GtkIMContextSimple` 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.
