Methods

  • Selects the specified column, adding it to the current column selection. Not all tables support column selection.

    Parameters

    • column: number

      the zero-indexed column number of the column being selected.

    Returns boolean

    TRUE if the specified column was successfully selected, FALSE if not.

  • Selects the specified row, adding it to the current row selection. Not all tables support row selection.

    Parameters

    • row: number

      the zero-indexed row number of the row being selected.

    Returns boolean

    TRUE if the specified row was successfully selected, FALSE if not.

  • Selects some text (adds a text selection) in an Atspi.Text object.

    Parameters

    • start_offset: number

      the starting offset of the desired new selection.

    • end_offset: number

      the offset of the first character after the new selection.

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • 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.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.

    If flags contains GObject.BindingFlags.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 GObject.Binding 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.Object can have multiple bindings.

    Parameters

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • 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.

    If flags contains GObject.BindingFlags.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 transform_from function is only used in case of bidirectional bindings, otherwise it will be ignored

    The binding will automatically be removed when either the source or the target instances are finalized. This will release the reference that is being held on the GObject.Binding instance; if you want to hold on to the GObject.Binding instance, you will need to hold a reference to it.

    To remove the binding, call g_binding_unbind().

    A GObject.Object can have multiple bindings.

    The same user_data parameter will be used for both transform_to and transform_from transformation functions; the notify function will be called once, when the binding is removed. If you need different data for each transformation function, please use g_object_bind_property_with_closures() instead.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target GObject.Object

    • target_property: string

      the property on target to bind

    • flags: GObject.BindingFlags

      flags to pass to GObject.Binding

    • Optionaltransform_to: BindingTransformFunc

      the transformation function from the source to the target, or null to use the default

    • Optionaltransform_from: BindingTransformFunc

      the transformation function from the target to the source, or null to use the default

    • Optionalnotify: DestroyNotify

      a function to call when disposing the binding, to free resources used by the transformation functions, or null if not required

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • 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

    • ...args: never[]

      the property on source to bind

    Returns any

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

    See atspi_selection_deselect_selected_child

    Parameters

    • child_index: number

      a gint indicating which of the children of the Atspi.Accessible is to be de-selected.

    Returns boolean

    TRUE if the child was successfully deselected, FALSE otherwise.

  • Removes a child from the selected children list of an Atspi.Selection. Note that child_index is the index in the selected-children list, not the index in the parent container. selectedChildIndex in this method, and child_index in atspi_selection_select_child are asymmetric.

    Parameters

    • selected_child_index: number

      a gint indicating which of the selected children of the Atspi.Accessible is to be selected.

    Returns boolean

    TRUE if the child was successfully deselected, FALSE otherwise.

    Returns boolean

    TRUE if the action is successfully invoked, otherwise FALSE.

  • This function is intended for GObject.Object 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

  • 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.Object::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

  • Gets the table cell at the specified row and column indices. To get the accessible object at a particular (x, y) screen coordinate, use atspi_component_get_accessible_at_point.

    A POSIX LC_MESSAGES-style locale value for image description and text.

  • Gets the 1-D child index corresponding to the specified 2-D row and column indices. To get the accessible object at a particular (x, y) screen coordinate, use atspi_component_get_accessible_at_point.

    see atspi_table_get_row_at_index, atspi_table_get_column_at_index

    Parameters

    • row: number

      the specified table row, zero-indexed.

    • column: number

      the specified table column, zero-indexed.

    Returns number

    a gint which serves as the index of a specified cell in the table, in a form usable by atspi_get_child_at_index.

  • A set of pointers to all interfaces supported by an Atspi.Accessible.

    Returns string[]

    A GLib.Array of strings describing the interfaces supported by the object. Interfaces are denoted in short-hand (i.e. "Component", "Text" etc.).

  • Get the keybindings for the i-th action invocable on an object implementing Atspi.Action, if any are defined. The keybindings string format is as follows: there are multiple parts to a keybinding string (typically 3). They are delimited with ";". The first is the action's keybinding which is usable if the object implementing the action is currently posted to the screen, e.g. if a menu is posted then these keybindings for the corresponding menu-items are available. The second keybinding substring is the full key sequence necessary to post the action's widget and activate it, e.g. for a menu item such as "File->Open" it would both post the menu and activate the item. Thus the second keybinding string is available during the lifetime of the containing toplevel window as a whole, whereas the first keybinding string only works while the object implementing AtkAction is posted. The third (and optional) keybinding string is the "keyboard shortcut" which invokes the action without posting any menus. Meta-keys are indicated by the conventional strings "<Control>", "<Alt>", "<Shift>", "<Mod2>", etc. (we use the same string as gtk_accelerator_name() in gtk+-2.X.

    Parameters

    • i: number

      an integer indicating which action to query.

    Returns string

    a UTF-8 string which can be parsed to determine the i-th invocable action's keybindings.

    Parameters

    • character_offset: number

      a gint specifying the character offset to query.

    Returns number

    the linkIndex of the Atspi.Hyperlink active at character offset character_offset, or -1 if there is no hyperlink at the specified character offset.

  • Gets the locale associated with the document's content, e.g. the locale for LOCALE_TYPE_MESSAGES.

    Returns string

    a string compliant with the POSIX standard for locale description.

  • Get the name of the 'i-th' action invocable on an object implementing Atspi.Action.

    Parameters

    • i: number

      an integer indicating which action to query.

    Returns string

    the name of the action, as a UTF-8 string.

  • Gets a UTF-8 string corresponding to the name of the role played by an object, translated to the current locale. This method will return useful values for roles that fall outside the enumeration used in atspi_accessible_getRole ().

    Returns string

    a localized, UTF-8 string specifying the type of UI role played by an Atspi.Accessible object.

  • Queries the z stacking order of a component which is in the MDI or window layer. (Bigger z-order numbers mean nearer the top)

    Returns number

    a gshort indicating the stacking order of the component in the MDI layer, or -1 if the component is not in the MDI layer.

  • Gets the number of columns in an Atspi.Table, exclusive of any columns that are programmatically hidden, but inclusive of columns that may be outside of the current scrolling window or viewport.

    Returns number

    a gint indicating the number of columns in the table.

    • y: number

      the y coordinate of the point to be queried.

    • type: Atspi.CoordType

      an Atspi.CoordType indicating the coordinate system in which the values should be returned.

    Returns number

    the offset (as a gint) at the point (x, y) in the specified coordinate system.

  • Returns the process id associated with the given accessible. Mainly added for debugging; it is a shortcut to explicitly querying the accessible's app->bus_name and then calling GetConnectionUnixProcessID.

    Returns number

    The process ID or undetermined value if error is set.

  • Gets a property of an object.

    The value can be:

    • an empty GObject.Value initialized by G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a GObject.Value initialized with the expected type of the property
    • a GObject.Value 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 GObject.Value.unset.

    Note that GObject.Object.get_property is really intended for language bindings, GObject.Object.get is much more convenient for C programming.

    Parameters

    Parameters

    • start_offset: number

      a gint indicating the offset of the first text character for whom boundary information is requested.

    • end_offset: number

      a gint indicating the offset of the text character after the last character for whom boundary information is requested.

    • type: Atspi.CoordType

      an Atspi.CoordType indicating the coordinate system to use for the returned values.

    Returns Atspi.Rect

    An Atspi.Rect giving the position and size of the specified range of text.

  • Gets a UTF-8 string corresponding to the name of the role played by an object. This method will return useful values for roles that fall outside the enumeration used in atspi_accessible_get_role ().

    Returns string

    a UTF-8 string specifying the type of UI role played by an Atspi.Accessible object.

  • Gets the table row index occupied by the child at a particular 1-D child index.

    Parameters

    • index: number

      the specified child index, zero-indexed.

    Returns number

    a gint indicating the first row spanned by the child of a table, at the specified 1-D (zero-offset) index.

  • Given a child index, determines the row and column indices and extents, and whether the cell is currently selected. If the child at index is not a cell (for instance, if it is a summary, caption, etc.), FALSE is returned. The returned values are meaningful only if the Table has both STATE_VISIBLE and STATE_SHOWING.

    Example: If the Atspi.Table child at index '6' extends across columns 5 and 6 of row 2 of an Atspi.Table instance, and is currently selected, then

    retval = atspi_table_get_row_column_extents_at_index (table, 6, row, col, row_extents, col_extents, is_selected);

    will return TRUE, and after the call row, col, row_extents, col_extents, and is_selected will contain 2, 5, 1, 2, and TRUE, respectively.

    Parameters

    • index: number

      the index of the Atspi.Table child whose row/column extents are requested.

    Returns [boolean, number, number, number, number, boolean]

    TRUE if the index is associated with a valid table cell, FALSE if the index does not correspond to a cell. If FALSE is returned, the values of the out parameters are undefined.

  • Gets the row and column indexes and extents of this cell accessible. The returned values are meaningful only if the table cell has both STATE_VISIBLE and STATE_SHOWING.

    Returns [number, number, number, number]

  • Gets a text description of a particular table row. This differs from atspi_table_get_row_header, which returns an Atspi.Accessible.

    Parameters

    • row: number

      the specified table row, zero-indexed.

    Returns string

    a UTF-8 string describing the specified table row, if available.

      the specified table row, zero-indexed.

    • column: number

      the specified table column, zero-indexed.

    Returns number

    a gint indicating the number of rows spanned by the specified cell.

  • Returns the number of rows occupied by this cell accessible. The returned values are meaningful only if the table cell has both STATE_VISIBLE and STATE_SHOWING.

    Returns number

    a gint representing the number of rows occupied by this cell, or 0 if the cell does not implement this method.

  • Gets the i-th selected Atspi.Accessible child of an Atspi.Selection. Note that selected_child_index refers to the index in the list of 'selected' children and generally differs from that used in atspi_accessible_get_child_at_index or returned by atspi_accessible_get_index_in_parent. selected_child_index must lie between 0 and atspi_selection_get_n_selected_children - 1, inclusive.

    Parameters

    • selected_child_index: number

      a gint indicating which of the selected children is specified.

    Returns Atspi.Accessible

    a pointer to a selected Atspi.Accessible child object, specified by selected_child_index.

  • Queries a table for a list of indices of columns which are currently selected.

    Returns number[]

    an array of gint values, specifying which columns are currently selected.

  • Queries a table for a list of indices of rows which are currently selected.

    Returns number[]

    an array of gint values, specifying which rows are currently selected.

  • Gets a portion of the text exposed through an Atspi.Text according to a given offset and a specific granularity, along with the start and end offsets defining the boundaries of such a portion of text.

    If granularity is ATSPI_TEXT_GRANULARITY_CHAR the character at the offset is returned.

    If granularity is ATSPI_TEXT_GRANULARITY_WORD the returned string is from the word start at or before the offset to the word start after the offset.

    The returned string will contain the word at the offset if the offset is inside a word and will contain the word before the offset if the offset is not inside a word.

    If granularity is ATSPI_TEXT_GRANULARITY_SENTENCE the returned string is from the sentence start at or before the offset to the sentence start after the offset.

    The returned string will contain the sentence at the offset if the offset is inside a sentence and will contain the sentence before the offset if the offset is not inside a sentence.

    If granularity is ATSPI_TEXT_GRANULARITY_LINE the returned string is from the line start at or before the offset to the line start after the offset.

    If granularity is ATSPI_TEXT_GRANULARITY_PARAGRAPH the returned string is from the start of the paragraph at or before the offset to the start of the following paragraph after the offset.

    Parameters

    Returns Atspi.TextRange

    a newly allocated string containing the text at the offset bounded by the specified granularity. Use g_free() to free the returned string. Returns null if the offset is invalid or no implementation is available.

  • Gets a range of text from an Atspi.Text object. The number of bytes in the returned string may exceed either end_offset or start_offset, since UTF-8 is a variable-width encoding.

    Parameters

    • start_offset: number

      a gint indicating the start of the desired text range.

    • end_offset: number

      a gint indicating the first character past the desired range.

    Returns string

    a text string containing characters from start_offset to end_offset-1, inclusive, encoded as UTF-8.

  • Parameters

    • ...args: never[]

    Returns any

  • Gets the value of a named attribute at a given offset.

    Parameters

    • offset: number

      The character offset at which to query the attribute.

    • attribute_name: string

      The attribute to query.

    Returns string

    the value of a given attribute at the given offset, or null if not present.

  • Gets the attributes applied to a range of text from an Atspi.Text object. The text attributes correspond to CSS attributes where possible. DEPRECATED

    Parameters

    • offset: number

      a gint indicating the offset from which the attribute search is based.

    Returns [GLib.HashTable<string, string>, number, number]

    a GLib.HashTable describing the attributes at the given character offset.

  • 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

  • Inserts text into an Atspi.EditableText object. As with all character offsets, the specified position may not be the same as the resulting byte offset, since the text is in a variable-width encoding.

    Parameters

    • position: number

      a gint indicating the character offset at which to insert the new text.

    • text: string

      a string representing the text to insert, in UTF-8 encoding.

    • length: number

      the number of characters of text to insert, in bytes. If the byte count of text is less than or equal to length, the entire contents of text will be inserted.

    Returns boolean

    TRUE if the operation was successful, otherwise FALSE.

  • Determines whether specified table column is selected. Not all tables support column selection.

    Parameters

    • column: number

      the zero-indexed column number of the column being queried.

    Returns boolean

    TRUE if the specified column is currently selected, FALSE if not.

  • Determines whether a table row is selected. Not all tables support row selection.

    Parameters

    • row: number

      the zero-indexed row number of the row being queried.

    Returns boolean

    TRUE if the specified row is currently selected, FALSE if not.

  • Determines whether the cell at a specific row and column is selected.

    Parameters

    • row: number

      the zero-indexed row of the cell being queried.

    • column: number

      the zero-indexed column of the cell being queried.

    Returns boolean

    TRUE if the specified cell is currently selected, FALSE if not.

  • 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

    • property_name: 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.:

      typedef enum
    {
    PROP_FOO = 1,
    PROP_LAST
    } MyObjectProperty;

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
    0, 100,
    50,
    G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
    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

    Returns void

  • Inserts text from the system clipboard into an Atspi.EditableText object. As with all character offsets, the specified position may not be the same as the resulting byte offset, since the text is in a variable-width encoding.

    Parameters

    • position: number

      a gint indicating the character offset at which to insert the new text.

    Returns boolean

    TRUE if the operation was successful, otherwise FALSE.

  • 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

    the same object

  • 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

    object

  • De-selects the specified column, removing it from the current column selection. Not all tables support column selection.

    Parameters

    • column: number

      the zero-indexed column number of the column being de-selected.

    Returns boolean

    TRUE if the specified column was successfully de-selected, FALSE if not.

  • De-selects the specified row, removing it from the current row selection. Not all tables support row selection.

    Parameters

    • row: number

      the zero-indexed number of the row being de-selected.

    Returns boolean

    TRUE if the specified row was successfully de-selected, FALSE if not.

  • De-selects a text selection.

    Parameters

    • selection_num: number

      a gint indicating which text selection to remove.

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • Scrolls whatever container of the Atspi.Text text range so it becomes visible on the screen.

    Parameters

    • start_offset: number

      a gint indicating the start of the desired text range.

    • end_offset: number

      a gint indicating the first character past the desired range.

    • type: Atspi.ScrollType

      a Atspi.ScrollType indicating where the object should be placed on the screen.

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • Scrolls whatever container of the Atspi.Text text range so it becomes visible on the screen at a given position.

    Parameters

    • start_offset: number

      a gint indicating the start of the desired text range.

    • end_offset: number

      a gint indicating the first character past the desired range.

    • coords: Atspi.CoordType

      a Atspi.CoordType indicating whether the coordinates are relative to the screen, to the window, or to the parent object.

    • x: number

      the x coordinate of the point to reach

    • y: number

      the y coordinate of the point to reach

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • Scrolls whatever container of the Atspi.Component object so it becomes visible on the screen at a given position.

    Parameters

    • coords: Atspi.CoordType

      a Atspi.CoordType indicating whether the coordinates are relative to the screen, to the window, or to the parent object.

    • x: number

      the x coordinate of the point to reach

    • y: number

      the y coordinate of the point to reach

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • Adds a child to the selected children list of an Atspi.Selection. For Atspi.Selection implementors that only allow single selections, this may replace the (single) current selection.

    Parameters

    • child_index: number

      a gint indicating which child of the Atspi.Accessible is to be selected.

    Returns boolean

    TRUE if the child was successfully selected, FALSE otherwise.

  • Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.

    Parameters

    • properties: { [key: string]: any }

      Object containing the properties to set

    Returns void

  • Sets the type of data to cache for accessibles. If this is not set for an application or is reset to ATSPI_CACHE_UNDEFINED, then the desktop's cache flag will be used. If the desktop's cache flag is also undefined, then all possible data will be cached. This function is intended to work around bugs in toolkits where the proper events are not raised / to aid in testing for such bugs.

    Parameters

    Returns void

  • Moves the text caret to a given position.

    Parameters

    • new_offset: number

      the offset to which the text caret is to be moved.

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • Sets the current value of an Atspi.Value.

    Parameters

    • new_value: number

      a gdouble value which is the desired new value of the object.

    Returns boolean

    TRUE if the value could be assigned the specified value, FALSE otherwise.

  • 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 GLib.Quark 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 GLib.Quark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optionaldata: any

      data to associate with that key

    Returns void

  • Moves and resizes the specified component.

    Parameters

      the new vertical position to which the component should be moved.

    • y: number

      the new horizontal position to which the component should be moved.

    • width: number

      the width to which the component should be resized.

    • height: number

      the height to which the component should be resized.

    • ctype: Atspi.CoordType

      the coordinate system in which the position is specified. (e.g. ATSPI_COORD_TYPE_WINDOW, ATSPI_COORD_TYPE_SCREEN).

    Returns boolean

    TRUE if successful; FALSE otherwise.

  • Moves the component to the specified position.

    Parameters

    • x: number

      the new vertical position to which the component should be moved.

    • y: number

      the new horizontal position to which the component should be moved.

    • ctype: Atspi.CoordType

      the coordinate system in which the position is specified. (e.g. ATSPI_COORD_TYPE_WINDOW, ATSPI_COORD_TYPE_SCREEN).

    Returns boolean

    TRUE if successful; FALSE otherwise.

  • Changes the bounds of an existing Atspi.Text text selection.

    Parameters

    • selection_num: number

      a zero-offset index indicating which text selection to modify.

    • start_offset: number

      a gint indicating the new starting offset for the selection.

    • end_offset: number

      a gint indicating the desired new offset of the first character after the selection.

    Returns boolean

    TRUE if successful, FALSE otherwise.

  • Resizes the specified component to the given coordinates.

    Parameters

    • width: number

      the width to which the component should be resized.

    • height: number

      the height to which the component should be resized.

    Returns boolean

    TRUE if successful; FALSE otherwise.

  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • key: string

      name of the key

    Returns any

    the data if found, or null if no such data exists.

  • 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 GLib.Quark, naming the user data pointer

    Returns any

    The user data pointer set, or null

  • 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.Object::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

  • 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.Object 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.Object instance. Use g_clear_object() for this.

    Returns void

  • the constructed function is called by g_object_new() as the final step of the object creation process. At the point of the call, all construction properties have been set on the object. The purpose of this call is to allow for object initialisation steps that can only be performed after construction properties have been set. constructed implementors should chain up to the constructed call of their parent class to allow it to complete its initialisation.

    Returns void

  • the dispose function is supposed to drop all references to other objects, but keep the instance otherwise intact, so that client method invocations still work. It may be run multiple times (due to reference loops). Before returning, dispose should chain up to the dispose method of the parent class.

    Returns 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

    Returns void

  • Parameters

    • current_offset: number
    • last_offset: number

    Returns void

  • the generic setter for all properties of this type. Should be overridden for every type with properties. If implementations of set_property don't emit property change notification explicitly, this will be done implicitly by the type system. However, if the notify signal is emitted explicitly, the type system will not emit it a second time.

    Parameters

    Returns 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

    Returns void

Methods - Inherited from Atspi.Object

  • 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 GObject.ParamSpec, 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 GObject.TypeInfo.) 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

    Returns void

  • Parameters

    • property_id: number

      the new property ID

    • name: string

      the name of a property registered in a parent class or in an interface of this class.

    Returns void
