Class
GtkIMContextSimple
Description [src]
class Gtk.IMContextSimple : Gtk.IMContext
{
/* No available fields */
}
GtkIMContextSimple is a simple input method context supporting table-based input methods. It has a built-in table of compose sequences that is derived from the X11 Compose files.
GtkIMContextSimple reads additional compose sequences from the first of the following files that is found: ~/.config/gtk-3.0/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.
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.
Instance methods
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.
Methods inherited from GtkIMContext (11)
gtk_im_context_delete_surrounding
Asks the widget that the input context is attached to to delete
characters around the cursor position by emitting the
GtkIMContext::delete_surrounding signal. Note that offset
and n_chars
are in characters not in bytes which differs from the usage other
places in GtkIMContext
.
gtk_im_context_filter_keypress
Allow an input method to internally handle key press and release
events. If this function returns TRUE
, then no further processing
should be done for this key event.
gtk_im_context_focus_in
Notify the input method that the widget to which this input context corresponds has gained focus. The input method may, for example, change the displayed feedback to reflect this change.
gtk_im_context_focus_out
Notify the input method that the widget to which this input context corresponds has lost focus. The input method may, for example, change the displayed feedback or reset the contexts state to reflect this change.
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. This string should be displayed inserted at the insertion point.
gtk_im_context_get_surrounding
Retrieves context around the insertion point. Input methods typically want context in order to constrain input text based on existing text; this is important for languages such as Thai where only some sequences of characters are allowed.
gtk_im_context_reset
Notify the input method that a change such as a change in cursor position has been made. This will typically cause the input method to clear the preedit state.
gtk_im_context_set_client_window
Set the client window for the input context; this is the
GdkWindow
in which the input appears. This window is
used in order to correctly position status windows, and may
also be used for purposes internal to the input method.
gtk_im_context_set_cursor_location
Notify the input method that a change in cursor position has been made. The location is relative to the client window.
gtk_im_context_set_surrounding
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.
gtk_im_context_set_use_preedit
Sets whether the IM context should use the preedit string
to display feedback. If use_preedit
is FALSE (default
is TRUE), then the IM context may use some other method to display
feedback, such as displaying it in a child of the root window.

Signals
Signals inherited from GtkIMContext (6)
GtkIMContext::commit
The ::commit signal is emitted when a complete input sequence has been entered by the user. This can be a single character immediately after a key press or the final result of preediting.
GtkIMContext::delete-surrounding
The ::delete-surrounding signal is emitted when the input method needs to delete all or part of the context surrounding the cursor.
GtkIMContext::preedit-changed
The ::preedit-changed signal is emitted whenever the preedit sequence
currently being entered has changed. It is also emitted at the end of
a preedit sequence, in which case
gtk_im_context_get_preedit_string()
returns the empty string.
GtkIMContext::preedit-end
The ::preedit-end signal is emitted when a preediting sequence has been completed or canceled.
GtkIMContext::preedit-start
The ::preedit-start signal is emitted when a new preediting sequence starts.
GtkIMContext::retrieve-surrounding
The ::retrieve-surrounding signal is emitted when the input method
requires the context surrounding the cursor. The callback should set
the input method surrounding context by calling the
gtk_im_context_set_surrounding()
method.
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
