parent: Gtk.ListStore
name: string

Methods

  • Adds a child to buildable. type is an optional string describing how the child should be added.

    Parameters

    Returns void

  • addFiles(fileList: Gio.File[]): void
  • Adds a list of #GFile's to store. The given list must be %NULL-terminated.

    If any of the #GFile's in file_list is a directory, all the images in that directory will be added to store. If the list of files contains only one file and this is a regular file, then all the images in the same directory will be added as well to store.

    Parameters

    • fileList: Gio.File[]

      A %NULL-terminated list of #GFile's.

    Returns void

  • Appends a new row to list_store. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

    Returns Gtk.TreeIter

  • Adds an #EogImage to store. The thumbnail of the image is not loaded and will only be loaded if the thumbnail is made visible.

    Parameters

    Returns void

  • 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:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • 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 the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transformFrom: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • clear(): void
  • Constructs a child of buildable with the name name.

    #GtkBuilder calls this function if a “constructor” has been specified in the UI definition.

    Parameters

    • builder: Gtk.Builder

      #GtkBuilder used to construct this object

    • name: string

      name of child to construct

    Returns GObject.Object

  • This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable.

    Parameters

    • builder: Gtk.Builder

      a #GtkBuilder

    • child: GObject.Object

      child object or %NULL for non-child tags

    • tagname: string

      the name of the tag

    • data: object

      user data created in custom_tag_start

    Returns void

  • This is called at the end of each custom element handled by the buildable.

    Parameters

    • builder: Gtk.Builder

      #GtkBuilder used to construct this object

    • child: GObject.Object

      child object or %NULL for non-child tags

    • tagname: string

      name of tag

    • data: object

      user data that will be passed in to parser functions

    Returns void

  • Asks the #GtkTreeDragSource to delete the row at path, because it was moved somewhere else via drag-and-drop. Returns %FALSE if the deletion fails because path no longer exists, or for some model-specific reason. Should robustly handle a path no longer found in the model!

    Parameters

    Returns boolean

  • Asks the #GtkTreeDragSource to fill in selection_data with a representation of the row at path. selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!

    Parameters

    Returns boolean

  • Asks the #GtkTreeDragDest to insert a row before the path dest, deriving the contents of the row from selection_data. If dest is outside the tree so that inserting before it is impossible, %FALSE will be returned. Also, %FALSE may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!

    Parameters

    Returns boolean

  • emit(sigName: "draw-thumbnail", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • forceFloating(): void
  • 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().

    Returns void

  • Calls func on each node in model in a depth-first fashion.

    If func returns %TRUE, then the tree ceases to be walked, and gtk_tree_model_foreach() returns.

    Parameters

    Returns void

  • freezeNotify(): void
  • 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.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • getColumnType(index: number): GType<unknown>
  • getData(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • Returns a set of flags supported by this interface.

    The flags are a bitwise combination of #GtkTreeModelFlags. The flags supported should not change during the lifetime of the tree_model.

    Returns Gtk.TreeModelFlags

  • Gets the #EogImage in the position pos of store. If there is no image at position pos, %NULL is returned.

    Parameters

    • pos: number

      the position of the required #EogImage.

    Returns Eog.Image

  • getInitialPos(): number
  • Gets the position of the #EogImage that should be loaded first. If not set, it returns -1.

    Returns number

  • getIterFromString(pathString: string): [boolean, Gtk.TreeIter]
  • Sets iter to a valid iterator pointing to path_string, if it exists. Otherwise, iter is left invalid and %FALSE is returned.

    Parameters

    • pathString: string

      a string representation of a #GtkTreePath-struct

    Returns [boolean, Gtk.TreeIter]

  • getNColumns(): number
  • getName(): string
  • Gets the name of the buildable object.

    #GtkBuilder sets the name based on the [GtkBuilder UI definition][BUILDER-UI] used to construct the buildable.

    Returns string

  • Gets the position where image is stored in store. If image is not stored in store, -1 is returned.

    Parameters

    Returns number

  • Gets the position of the image pointed by iter.

    Parameters

    • iter: Gtk.TreeIter

      A #GtkTreeIter pointing to an image in store.

    Returns number

  • getProperty(propertyName?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    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.

    Parameters

    • Optional propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • Fills in sort_column_id and order with the current sort column and the order. It returns %TRUE unless the sort_column_id is %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or %GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.

    Returns [boolean, number, Gtk.SortType]

  • Generates a string representation of the iter.

    This string is a “:” separated list of numbers. For example, “4:10:0:3” would be an acceptable return value for this string.

    Parameters

    Returns string

  • Initializes and sets value to that at column.

    When done with value, g_value_unset() needs to be called to free any allocated memory.

    Parameters

    • iter: Gtk.TreeIter

      the #GtkTreeIter-struct

    • column: number

      the column to lookup the value at

    Returns any

  • getv(names: string[], values: any[]): void
  • 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.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • hasDefaultSortFunc(): boolean
  • Returns %TRUE if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.

    Returns boolean

  • Creates a new row at position. iter will be changed to point to this new row. If position is -1 or is larger than the number of rows on the list, then the new row will be appended to the list. The row will be empty after this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

    Parameters

    • position: number

      position to insert the new row, or -1 for last

    Returns Gtk.TreeIter

  • Inserts a new row after sibling. If sibling is %NULL, then the row will be prepended to the beginning of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

    Parameters

    Returns Gtk.TreeIter

  • Inserts a new row before sibling. If sibling is %NULL, then the row will be appended to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

    Parameters

    Returns Gtk.TreeIter

  • insertWithValuesv(position: number, columns: number[], values: any[]): Gtk.TreeIter
  • A variant of gtk_list_store_insert_with_values() which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language-bindings.

    Parameters

    • position: number

      position to insert the new row, or -1 for last

    • columns: number[]

      an array of column numbers

    • values: any[]

      an array of GValues

    Returns Gtk.TreeIter

  • isFloating(): boolean
  • Sets iter to point to the first child of parent.

    If parent has no children, %FALSE is returned and iter is set to be invalid. parent will remain a valid node after this function has been called.

    If parent is %NULL returns the first node, equivalent to gtk_tree_model_get_iter_first (tree_model, iter);

    Parameters

    • parent: Gtk.TreeIter

      the #GtkTreeIter-struct, or %NULL

    Returns [boolean, Gtk.TreeIter]

  • This function is slow. Only use it for debugging and/or testing purposes.

    Checks if the given iter is a valid iter for this #GtkListStore.

    Parameters

    Returns boolean

  • Returns the number of children that iter has.

    As a special case, if iter is %NULL, then the number of toplevel nodes is returned.

    Parameters

    Returns number

  • Sets iter to point to the node following it at the current level.

    If there is no next iter, %FALSE is returned and iter is set to be invalid.

    Parameters

    Returns boolean

  • Sets iter to be the child of parent, using the given index.

    The first index is 0. If n is too big, or parent has no children, iter is set to an invalid iterator and %FALSE is returned. parent will remain a valid node after this function has been called. As a special case, if parent is %NULL, then the n-th root node is set.

    Parameters

    • parent: Gtk.TreeIter

      the #GtkTreeIter-struct to get the child from, or %NULL.

    • n: number

      the index of the desired child

    Returns [boolean, Gtk.TreeIter]

  • Sets iter to be the parent of child.

    If child is at the toplevel, and doesn’t have a parent, then iter is set to an invalid iterator and %FALSE is returned. child will remain a valid node after this function has been called.

    iter will be initialized before the lookup is performed, so child and iter cannot point to the same memory location.

    Parameters

    Returns [boolean, Gtk.TreeIter]

  • Sets iter to point to the previous node at the current level.

    If there is no previous iter, %FALSE is returned and iter is set to be invalid.

    Parameters

    Returns boolean

  • length(): number
  • Returns the number of images in the store.

    Returns number

  • Moves iter in store to the position after position. Note that this function only works with unsorted stores. If position is %NULL, iter will be moved to the start of the list.

    Parameters

    Returns void

  • Moves iter in store to the position before position. Note that this function only works with unsorted stores. If position is %NULL, iter will be moved to the end of the list.

    Parameters

    Returns void

  • notify(propertyName: string): void
  • 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.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • propertyName: string

      the name of a property installed on the class of object.

    Returns void

  • 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 g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns void

  • on(sigName: "draw-thumbnail", callback: ListStore_DrawThumbnailSignalCallback, after?: boolean): EventEmitter
  • on(sigName: string, callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • once(sigName: "draw-thumbnail", callback: ListStore_DrawThumbnailSignalCallback, after?: boolean): EventEmitter
  • once(sigName: string, callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • 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.

    Parameters

    Returns void

  • Prepends a new row to list_store. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

    Returns Gtk.TreeIter

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Lets the tree ref the node.

    This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons.

    This function is primarily meant as a way for views to let caching models know when nodes are being displayed (and hence, whether or not to cache that node). Being displayed means a node is in an expanded branch, regardless of whether the node is currently visible in the viewport. For example, a file-system based model would not want to keep the entire file-hierarchy in memory, just the sections that are currently being displayed by every current view.

    A model should be expected to be able to get an iter independent of its reffed state.

    Parameters

    Returns void

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] 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 GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • Removes the given row from the list store. After being removed, iter is set to be the next valid row, or invalidated if it pointed to the last row in list_store.

    Parameters

    Returns boolean

  • reorder(newOrder: number[]): void
  • Reorders store to follow the order indicated by new_order. Note that this function only works with unsorted stores.

    Parameters

    • newOrder: number[]

      an array of integers mapping the new position of each child to its old position before the re-ordering, i.e. new_order``[newpos] = oldpos. It must have exactly as many items as the list store’s length.

    Returns void

  • Emits the #GtkTreeModel::row-deleted signal on tree_model.

    This should be called by models after a row has been removed. The location pointed to by path should be the location that the row previously was at. It may not be a valid location anymore.

    Nodes that are deleted are not unreffed, this means that any outstanding references on the deleted node should not be released.

    Parameters

    • path: Gtk.TreePath

      a #GtkTreePath-struct pointing to the previous location of the deleted row

    Returns void

  • Asks the #GtkTreeDragSource whether a particular row can be used as the source of a DND operation. If the source doesn’t implement this interface, the row is assumed draggable.

    Parameters

    • path: Gtk.TreePath

      row on which user is initiating a drag

    Returns boolean

  • Determines whether a drop is possible before the given dest_path, at the same depth as dest_path. i.e., can we drop the data in selection_data at that location. dest_path does not have to exist; the return value will almost certainly be %FALSE if the parent of dest_path doesn’t exist, though.

    Parameters

    Returns boolean

  • Emits the #GtkTreeModel::row-has-child-toggled signal on tree_model. This should be called by models after the child state of a node changes.

    Parameters

    • path: Gtk.TreePath

      a #GtkTreePath-struct pointing to the changed row

    • iter: Gtk.TreeIter

      a valid #GtkTreeIter-struct pointing to the changed row

    Returns void

  • Emits the #GtkTreeModel::rows-reordered signal on tree_model.

    This should be called by models when their rows have been reordered.

    Parameters

    • path: Gtk.TreePath

      a #GtkTreePath-struct pointing to the tree node whose children have been reordered

    • iter: Gtk.TreeIter

      a valid #GtkTreeIter-struct pointing to the node whose children have been reordered, or %NULL if the depth of path is 0

    • newOrder: number[]

      an array of integers mapping the current position of each child to its old position before the re-ordering, i.e. new_order``[newpos] = oldpos

    Returns void

  • runDispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • set(iter: Gtk.TreeIter, columns: number[], values: any[]): void
  • A variant of gtk_list_store_set_valist() which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language-bindings and in case the number of columns to change is not known until run-time.

    Parameters

    • iter: Gtk.TreeIter

      A valid #GtkTreeIter for the row being modified

    • columns: number[]

      an array of column numbers

    • values: any[]

      an array of GValues

    Returns void

  • setBuildableProperty(builder: Gtk.Builder, name: string, value: any): void
  • setColumnTypes(types: GType<unknown>[]): void
  • This function is meant primarily for #GObjects that inherit from #GtkListStore, and should only be used when constructing a new #GtkListStore. It will not function after a row has been added, or a method on the #GtkTreeModel interface is called.

    Parameters

    • types: GType<unknown>[]

      An array length n of #GTypes

    Returns void

  • setData(key: string, data?: object): void
  • 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.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.

    If sort_func is %NULL, then there will be no default comparison function. This means that once the model has been sorted, it can’t go back to the default state. In this case, when the current sort column id of sortable is %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.

    Parameters

    Returns void

  • setName(name: string): void
  • setProperty(propertyName: string, value?: any): void
  • setSortColumnId(sortColumnId: number, order: Gtk.SortType): void
  • Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a #GtkTreeSortable::sort-column-changed signal. sort_column_id may either be a regular column id, or one of the following special values:

    • %GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID: the default sort function will be used, if it is set

    • %GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID: no sorting will occur

    Parameters

    • sortColumnId: number

      the sort column id to set

    • order: Gtk.SortType

      The sort order of the column

    Returns void

  • Sets the comparison function used when sorting to be sort_func. If the current sort column id of sortable is the same as sort_column_id, then the model will sort using this function.

    Parameters

    • sortColumnId: number

      the sort column id to set the function for

    • sortFunc: Gtk.TreeIterCompareFunc

      The comparison function

    Returns void

  • setValue(iter: Gtk.TreeIter, column: number, value: any): void
  • Sets the data in the cell specified by iter and column. The type of value must be convertible to the type of the column.

    Parameters

    • iter: Gtk.TreeIter

      A valid #GtkTreeIter for the row being modified

    • column: number

      column number to modify

    • value: any

      new value for the cell

    Returns void

  • sortColumnChanged(): void
  • stealData(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • stealQdata(quark: number): object
  • 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:

    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");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • thawNotify(): void
  • 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.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • Refreshes the thumbnail for the image pointed by iter.

    Parameters

    • iter: Gtk.TreeIter

      A #GtkTreeIter pointing to an image in store.

    Returns void

  • Sets the thumbnail for the image pointed by iter.

    Parameters

    • iter: Gtk.TreeIter

      A #GtkTreeIter pointing to an image in store.

    Returns void

  • Unsets the thumbnail for the image pointed by iter, changing it to a "busy" icon.

    Parameters

    • iter: Gtk.TreeIter

      A #GtkTreeIter pointing to an image in store.

    Returns void

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • Lets the tree unref the node.

    This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons. For more information on what this means, see gtk_tree_model_ref_node().

    Please note that nodes that are deleted are not unreffed.

    Parameters

    Returns void

  • watchClosure(closure: TClosure<any, any>): void
  • 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.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compatControl(what: number, data: object): number
  • 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().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • propertyName: string

      name of a property to look up.

    Returns ParamSpec

  • 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.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • 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().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Creates a new #EogListStore from a list of #EogImage's. The given list must be %NULL-terminated.

    Parameters

    • list: Eog.Image[]

      a %NULL-terminated list of #EogImage's.

    Returns Eog.ListStore

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
