class: GtkIMContextSimple

[30:7] extends: object

Supports compose sequences, dead keys and numeric Unicode input. ## 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 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 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.

Methods

GtkIMContextSimple (Handle = null)

Creates a new GtkIMContextSimple.
- @p Handle is an optional native handle or wrapper whose handle to adopt; when the native constructor is called.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
asIMContext ()

Wraps this handle as GtkIMContext.
- @r A GtkIMContext object.
add_compose_file (string compose_file)

Adds an additional table from the X11 compose file.
- @p compose_file is The path of compose file.
- @r None.
add_table (list data, int max_seq_len, int n_seqs)

Adds an additional table to search to the input context. Each row of the table consists of @max_seq_len key symbols followed by two #guint16 interpreted as the high and low words of a #gunicode value. Tables are searched starting from the last added. The table must be sorted in dictionary order on the numeric value of the key symbol fields. (Values beyond the length of the sequence should be zero.)
- @p data is the table.
- @p max_seq_len is Maximum length of a sequence in the table.
- @p n_seqs is number of sequences in the table.
- @r None.
