Sets our main struct and passes it to the parent class.
Creates a new #GtkEntryCompletion object.
Creates a new #GtkEntryCompletion object using the specified @area to layout cells in the underlying #GtkTreeViewColumn for the drop-down menu.
Gets emitted when an action is activated.
Gets emitted when a match from the cursor is on a match of the list. The default behaviour is to replace the contents of the entry with the contents of the text column in the row pointed to by @iter.
Gets emitted when the inline autocompletion is triggered. The default behaviour is to make the entry display the whole prefix and select the newly inserted part.
Gets emitted when a match from the list is selected. The default behaviour is to replace the contents of the entry with the contents of the text column in the row pointed to by @iter.
Gets emitted when the filter model has zero number of rows in completion_complete method. (In other words when GtkEntryCompletion is out of suggestions)
Requests a completion operation, or in other words a refiltering of the current list with completions, using the current key. The completion list view will be updated accordingly.
Computes the common prefix that is shared by all rows in @completion that start with @key. If no row matches @key, %NULL will be returned. Note that a text column must have been set for this function to work, see gtk_entry_completion_set_text_column() for details.
Deletes the action at @index_ from @completion’s action list.
Get the original text entered by the user that triggered the completion or %NULL if there’s no completion ongoing.
Gets the entry @completion has been attached to.
Get the main Gtk struct
Returns whether the common prefix of the possible completions should be automatically inserted in the entry.
Returns %TRUE if inline-selection mode is turned on.
Returns the minimum key length as set for @completion.
Returns the model the #GtkEntryCompletion is using as data source. Returns %NULL if the model is unset.
Returns whether the completions should be presented in a popup window.
Returns whether the completion popup window will be resized to the width of the entry.
Returns whether the completion popup window will appear even if there is only a single match.
the main Gtk struct as a void*
Returns the column in the model of @completion to get strings from.
Inserts an action in @completion’s action item list at position @index_ with markup @markup.
Inserts an action in @completion’s action item list at position @index_ with text @text. If you want the action item to have markup, use gtk_entry_completion_insert_action_markup().
Requests a prefix insertion.
Sets whether the common prefix of the possible completions should be automatically inserted in the entry.
Sets whether it is possible to cycle through the possible completions inside the entry.
Sets the match function for @completion to be @func. The match function is used to determine if a row should or should not be in the completion list.
Requires the length of the search key for @completion to be at least @length. This is useful for long lists, where completing using a small key takes a lot of time and will come up with meaningless results anyway (ie, a too large dataset).
Sets the model for a #GtkEntryCompletion. If @completion already has a model set, it will remove it before setting the new model. If model is %NULL, then it will unset the model.
Sets whether the completions should be presented in a popup window.
Sets whether the completion popup window will be resized to be the same width as the entry.
Sets whether the completion popup window will appear even if there is only a single match. You may want to set this to %FALSE if you are using [inline completion][GtkEntryCompletion--inline-completion].
Convenience function for setting up the most used case of this code: a completion list with just strings. This function will set up @completion to have a list displaying all (and just) strings in the completion list, and to get those strings from @column in the model of @completion.

Gets a D Object from the objects table of associations.
The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.
Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
Lists the properties of an interface.Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().
Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.
Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.
Creates a binding between @source_property on @source and @target_property on @target. Whenever the @source_property is changed the @target_property is updated using the same value. For instance:
Complete version of g_object_bind_property().
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 is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
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 g_object_ref_sink().
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 g_object_set_data()).
Gets a property of an object. @value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init().
This function gets back user data pointers stored via g_object_set_qdata().
Gets properties of an object.
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.
Increases the reference count of @object.
Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().
Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.
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.
Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.
Sets a property on an object.
This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.
This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.
Sets properties 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 g_object_set_qdata() 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: |[<!-- language="C" --> void object_add_to_user_list (GObject *object, const gchar *new_string) { // the quark, naming the object data GQuark quark_string_list = g_quark_from_static_string ("my-string-list"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);
Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on @object and when it reaches zero, queued "notify" signals are emitted.
Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
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 g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_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.
Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback to an object.
Clears a reference to a #GObject.

Adds a child to @buildable. @type is an optional string describing how the child should be added.
Constructs a child of @buildable with the name @name.
This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the @buildable.
This is called at the end of each custom element handled by the buildable.
This is called for each unknown element under <child>.
Get the internal child called @childname of the @buildable object.
Gets the name of the @buildable object.
Called when the builder finishes the parsing of a [GtkBuilder UI definition][BUILDER-UI]. Note that this will be called once for each time gtk_builder_add_from_file() or gtk_builder_add_from_string() is called on a builder.
Sets the property name @name to @value on the @buildable object.
Sets the name of the @buildable object.

Adds an attribute mapping to the list in @cell_layout.
Unsets all the mappings on all renderers on @cell_layout and removes all renderers from @cell_layout.
Clears all existing attributes previously set with gtk_cell_layout_set_attributes().
Returns the underlying #GtkCellArea which might be @cell_layout if called on a #GtkCellArea or might be %NULL if no #GtkCellArea is used by @cell_layout.
Returns the cell renderers which have been added to @cell_layout.
Adds the @cell to the end of @cell_layout. If @expand is %FALSE, then the @cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which @expand is %TRUE.
Packs the @cell into the beginning of @cell_layout. If @expand is %FALSE, then the @cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which @expand is %TRUE.
Re-inserts @cell at @position.
Sets the #GtkCellLayoutDataFunc to use for @cell_layout.
#GtkEntryCompletion is an auxiliary object to be used in conjunction with #GtkEntry to provide the completion functionality. It implements the #GtkCellLayout interface, to allow the user to add extra cells to the #GtkTreeView with completion matches.
“Completion functionality” means that when the user modifies the text in the entry, #GtkEntryCompletion checks which rows in the model match the current content of the entry, and displays a list of matches. By default, the matching is done by comparing the entry text case-insensitively against the text column of the model (see gtk_entry_completion_set_text_column()), but this can be overridden with a custom match function (see gtk_entry_completion_set_match_func()).
When the user selects a completion, the content of the entry is updated. By default, the content of the entry is replaced by the text column of the model, but this can be overridden by connecting to the #GtkEntryCompletion::match-selected signal and updating the entry in the signal handler. Note that you should return %TRUE from the signal handler to suppress the default behaviour.
To add completion functionality to an entry, use gtk_entry_set_completion().
In addition to regular completion matches, which will be inserted into the entry when they are selected, #GtkEntryCompletion also allows to display “actions” in the popup window. Their appearance is similar to menuitems, to differentiate them clearly from completion strings. When an action is selected, the #GtkEntryCompletion::action-activated signal is emitted.
GtkEntryCompletion uses a #GtkTreeModelFilter model to represent the subset of the entire model that is currently matching. While the GtkEntryCompletion signals #GtkEntryCompletion::match-selected and #GtkEntryCompletion::cursor-on-match take the original model and an iter pointing to that model as arguments, other callbacks and signals (such as #GtkCellLayoutDataFuncs or #GtkCellArea::apply-attributes) will generally take the filter model as argument. As long as you are only calling gtk_tree_model_get(), this will make no difference to you. If for some reason, you need the original model, use gtk_tree_model_filter_get_model(). Don’t forget to use gtk_tree_model_filter_convert_iter_to_child_iter() to obtain a matching iter.
