Class

GtkIMContextSimple

Description [src]

class Gtk.IMContextSimple : Gtk.IMContext {
  object: GtkIMContext
}

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). The syntax of these files is described in the Compose(5) manual page.

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.

Ancestors

Constructors

gtk_im_context_simple_new

Creates a new GtkIMContextSimple.

Instance methods

gtk_im_context_simple_add_compose_file

Adds an additional table from the X11 compose file.

gtk_im_context_simple_add_table

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.

Deprecated since: 4.4

Methods inherited from GtkIMContext (14)
gtk_im_context_delete_surrounding

Asks the widget that the input context is attached to delete characters around the cursor position by emitting the ::delete_surrounding signal.

gtk_im_context_filter_key

Allow an input method to forward key press and release events to another input method without necessarily having a GdkEvent available.

gtk_im_context_filter_keypress

Allow an input method to internally handle key press and release events.

gtk_im_context_focus_in

Notify the input method that the widget to which this input context corresponds has gained focus.

gtk_im_context_focus_out

Notify the input method that the widget to which this input context corresponds has lost focus.

gtk_im_context_get_preedit_string

Retrieve the current preedit string for the input context, and a list of attributes to apply to the string.

gtk_im_context_get_surrounding

Retrieves context around the insertion point.

Deprecated since: 4.2

gtk_im_context_get_surrounding_with_selection

Retrieves context around the insertion point.

Available since: 4.2

gtk_im_context_reset

Notify the input method that a change such as a change in cursor position has been made.

gtk_im_context_set_client_widget

Set the client widget for the input context.

gtk_im_context_set_cursor_location

Notify the input method that a change in cursor position has been made.

gtk_im_context_set_surrounding

Sets surrounding context around the insertion point and preedit string.

Deprecated since: 4.2

gtk_im_context_set_surrounding_with_selection

Sets surrounding context around the insertion point and preedit string. This function is expected to be called in response to the GtkIMContext::retrieve-surrounding signal, and will likely have no effect if called at other times.

Available since: 4.2

gtk_im_context_set_use_preedit

Sets whether the IM context should use the preedit string to display feedback.

Signals

Signals inherited from GtkIMContext (6)
Gtk.IMContext::commit

The ::commit signal is emitted when a complete input sequence has been entered by the user.

Gtk.IMContext::delete-surrounding

The ::delete-surrounding signal is emitted when the input method needs to delete all or part of the context surrounding the cursor.

Gtk.IMContext::preedit-changed

The ::preedit-changed signal is emitted whenever the preedit sequence currently being entered has changed.

Gtk.IMContext::preedit-end

The ::preedit-end signal is emitted when a preediting sequence has been completed or canceled.

Gtk.IMContext::preedit-start

The ::preedit-start signal is emitted when a new preediting sequence starts.

Gtk.IMContext::retrieve-surrounding

The ::retrieve-surrounding signal is emitted when the input method requires the context surrounding the cursor.
