Asks the widget that the input context is attached to delete characters around the cursor position by emitting the ::delete_surrounding signal.
Allow an input method to forward key press and release events to another input method without necessarily having a gdk.event.Event available.
Allow an input method to internally handle key press and release events.
Notify the input method that the widget to which this input context corresponds has gained focus.
Notify the input method that the widget to which this input context corresponds has lost focus.
Retrieve the current preedit string for the input context, and a list of attributes to apply to the string.
Retrieves context around the insertion point.
Retrieves context around the insertion point.
Notify the input method that a change such as a change in cursor position has been made.
Set the client widget for the input context.
Notify the input method that a change in cursor position has been made.
Sets surrounding context around the insertion point and preedit string.
Sets surrounding context around the insertion point and preedit string. This function is expected to be called in response to the signalGtk.IMContext::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.
Set the GObject of a D ObjectG wrapper.
Get a pointer to the underlying C object.
Calls g_object_ref() on a GObject.
Calls g_object_unref() on a GObject.
Get the GType of an object.
GObject GType property.
Convenience method to return this cast to a type. For use in D with statements.
Template to get the D object from a C GObject and cast it to the given D object type.
Connect a D closure to an object signal.
Template for setting a GObject property.
Template for getting a GObject property.
Creates a binding between source_property on source and target_property on target.
Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
Gets a property of an object.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Checks whether object has a floating[floating-ref] reference.
Emits a "notify" signal for the property property_name on object.
Emits a "notify" signal for the property specified by pspec on object.
Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Sets a property on an object.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

gtk.imcontext.IMContext defines the interface for GTK input methods.
gtk.imcontext.IMContext is used by GTK text input widgets like gtk.text.Text to map from key events to Unicode character strings.
An input method may consume multiple key events in sequence before finally outputting the composed result. This is called *preediting*, and an input method may provide feedback about this process by displaying the intermediate composition states as preedit text. To do so, the gtk.imcontext.IMContext will emit signal@Gtk.IMContext::preedit-start, signal@Gtk.IMContext::preedit-changed and signal@Gtk.IMContext::preedit-end signals.
For instance, the built-in GTK input method gtk.imcontext_simple.IMContextSimple implements the input of arbitrary Unicode code points by holding down the <kbd>Control</kbd> and <kbd>Shift</kbd> keys and then typing <kbd>u</kbd> followed by the hexadecimal digits of the code point. When releasing the <kbd>Control</kbd> and <kbd>Shift</kbd> keys, preediting ends and the character is inserted as text. For example,
Ctrl+Shift+u 2 0 A C
results in the € sign.
Additional input methods can be made available for use by GTK widgets as loadable modules. An input method module is a small shared library which provides a gio.ioextension.IOExtension for the extension point named "gtk-im-module".
To connect a widget to the users preferred input method, you should use gtk.immulticontext.IMMulticontext.
