Sets our main struct and passes it to the parent class.
Creates a new #GtkIMMulticontext.
Add menuitems for various available input methods to a menu; the menuitems, when selected, will switch the input method for the context and the global default input method.
Gets the id of the currently active slave of the @context.
Get the main Gtk struct

Sets the context id for @context.

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.
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.
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.
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.
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.
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.
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.
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.
Notify the input method that a change in cursor position has been made. The location is relative to the client window.
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.
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.
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.
The ::delete-surrounding signal is emitted when the input method needs to delete all or part of the context surrounding the cursor.
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.
The ::preedit-end signal is emitted when a preediting sequence has been completed or canceled.
The ::preedit-start signal is emitted when a new preediting sequence starts.
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.
