Creates a new GtkEntryCompletion object. Since 2.4
Gets emitted when an action is activated. Since 2.4
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. TRUE if the signal has been handled Since 2.12
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. Applications may connect to this signal in order to insert only a smaller part of the prefix into the entry - e.g. the entry used in the GtkFileChooser inserts only the part of the prefix up to the next '/'. TRUE if the signal has been handled Since 2.6
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. TRUE if the signal has been handled Since 2.4
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. Since 2.4
Deletes the action at index_ from completion's action list. Since 2.4
Get the original text entered by the user that triggered the completion or NULL if there's no completion ongoing. Since 2.12
Gets the entry completion has been attached to. Since 2.4
Returns whether the common prefix of the possible completions should be automatically inserted in the entry. Since 2.6
Returns TRUE if inline-selection mode is turned on. Since 2.12
Returns the minimum key length as set for completion. Since 2.4
Returns the model the GtkEntryCompletion is using as data source. Returns NULL if the model is unset. Since 2.4
Returns whether the completions should be presented in a popup window. Since 2.6
Returns whether the completion popup window will be resized to the width of the entry. Since 2.8
Returns whether the completion popup window will appear even if there is only a single match. Since 2.8

Returns the column in the model of completion to get strings from. Since 2.6
Inserts an action in completion's action item list at position index_ with markup markup. Since 2.4
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(). Since 2.4
Requests a prefix insertion. Since 2.6
Sets whether the common prefix of the possible completions should be automatically inserted in the entry. Since 2.6
Sets whether it is possible to cycle through the possible completions inside the entry. Since 2.12
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. Since 2.4
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). Since 2.4
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. Since 2.4
Sets whether the completions should be presented in a popup window. Since 2.6
Sets whether the completion popup window will be resized to be the same width as the entry. Since 2.8
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. Since 2.8
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. This functions creates and adds a GtkCellRendererText for the selected column. If you need to set the text column, but don't want the cell renderer, use g_object_set() to set the ::text_column property directly. Since 2.4

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. This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the It is important to note that you must use canonical parameter names as detail strings for the notify signal. See Also GParamSpecObject, g_param_spec_object()
Installs a new property. This is usually done in the class initializer. Note that it is possible to redefine a property in a derived class, by installing a property with the same name. This can be useful at times, e.g. to change the range of allowed values or the default value.
Installs new properties from an array of GParamSpecs. This is usually done in the class initializer. The property id of each property is the index of each GParamSpec in the pspecs array. The property id of 0 is treated specially by GObject and it should not be used to store a GParamSpec. This function should be used if you plan to use a static array of GParamSpecs and g_object_notify_by_pspec(). For instance, this Since 2.26
Looks up the GParamSpec for a property of a class.
Get an array of GParamSpec* for all properties of a class.
Registers property_id as referring to a property with the name name in a parent class or in an interface implemented by oclass. This allows this class to override a property implementation in a parent class or to provide the implementation of a property from an interface. Note Internally, overriding is implemented by creating a property of type GParamSpecOverride; generally operations that query the properties of the object class, such as g_object_class_find_property() or g_object_class_list_properties() will return the overridden property. However, in one case, the construct_properties argument of the constructor virtual function, the GParamSpecOverride is passed instead, so that the param_id field of the GParamSpec will be correct. For virtually all uses, this makes no difference. If you need to get the overridden property, you can call g_param_spec_get_redirect_target(). Since 2.4
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. This function is meant to be called from the interface's default vtable initialization function (the class_init member of GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface. Since 2.4
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(). Since 2.4
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(). Since 2.4
Increases the reference count of object.
Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
Increase the reference count of object, and possibly remove the floating reference, if object has a floating reference. In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one. Since 2.10
Clears a reference to a GObject. object_ptr must not be NULL. If the reference is NULL then this function does nothing. Otherwise, the reference count of the object is decreased and the pointer is set to NULL. This function is threadsafe and modifies the pointer atomically, using memory barriers where needed. A macro is also included that allows this function to be used without pointer casts. Since 2.28
Checks whether object has a floating reference. Since 2.10
This function is intended for GObject implementations to re-enforce a floating object reference. Doing this is seldomly required: all GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink(). Since 2.10
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.
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.
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().
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. This functionality is intended for binding object to a proxy object managed by another memory manager. This is done with two paired references: the strong reference added by g_object_add_toggle_ref() and a reverse reference to the proxy object which is either a strong reference or weak reference. The setup is that when there are no other references to object, only a weak reference is held in the reverse direction from object to the proxy object, but when there are other references held to object, a strong reference is held. The notify callback is called when the reference from object to the proxy object should be toggled from strong to weak (is_last_ref true) or weak to strong (is_last_ref false). Since a (normal) reference must be held to the object before calling g_object_toggle_ref(), the initial state of the reverse link is always strong. Multiple toggle references may be added to the same gobject, however if there are multiple toggle references to an object, none of them will ever be notified until all but one are removed. For this reason, you should only ever use a toggle reference if there is important state in the proxy object. Since 2.8
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one. Since 2.8
Emits a "notify" signal for the property property_name on object. When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Emits a "notify" signal for the property specified by pspec on object. This function omits the property name lookup, hence it is faster than g_object_notify(). One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with Since 2.26
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. This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, all queued "notify" signals are emitted. It is an error to call this function when the freeze count is zero.
Gets a named field from the objects table of associations (see g_object_set_data()).
Each object carries around a table of associations from strings to pointers. This function lets you set an association. If the object already had an association with that name, the old association will be destroyed.
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. Note that the destroy callback is not called if data is NULL.
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().
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.
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
Sets a property on an object.
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(). In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset(). Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.
Sets properties on an object.
Gets properties of an object. In general, a copy is made of the property contents and the caller is responsible for freeing the memory in the appropriate manner for the type, for instance by calling g_free() or g_object_unref(). See g_object_get().
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.
Releases all references to other objects. This can be used to break reference cycles. This functions should only be called from object system implementations.

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. Note that reusing the same cell renderer is not supported. Since 2.4
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. Note that reusing the same cell renderer is not supported. Since 2.4
Returns the cell renderers which have been added to cell_layout. Since 2.12
Re-inserts cell at position. Note that cell has already to be packed into cell_layout for this to function properly. Since 2.4
Unsets all the mappings on all renderers on cell_layout and removes all renderers from cell_layout. Since 2.4
Adds an attribute mapping to the list in cell_layout. The column is the column of the model to get a value from, and the attribute is the parameter on cell to be set from the value. So for example if column 2 of the model contains strings, you could have the "text" attribute of a GtkCellRendererText get its values from column 2. Since 2.4
Sets the GtkCellLayoutDataFunc to use for cell_layout. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of cell_layout's cell renderer(s) as appropriate. func may be NULL to remove and older one. Since 2.4
Clears all existing attributes previously set with gtk_cell_layout_set_attributes(). Since 2.4
Description 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 ::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 ::action-activated signal is emitted.
