## Object Hierarchy

## Description

GtkWindowGroup objects are referenced by each window in the group, so once you have added all windows to a GtkWindowGroup, you can drop the initial reference to the window group with `g_object_unref()`. If the windows in the window group are subsequently destroyed, then they will be removed from the window group and drop their references on the window group; when all window have been removed, the window group will be freed.

### gtk_window_group_new ()

    GtkWindowGroup *    gtk_window_group_new                (void);

Creates a new GtkWindowGroup object. Grabs added with `gtk_grab_add()` only affect windows within the same GtkWindowGroup.

Returns : | a new GtkWindowGroup.

### gtk_window_group_add_window ()

    void                gtk_window_group_add_window         (GtkWindowGroup *window_group,
                                                             GtkWindow *window);

Adds a window to a GtkWindowGroup.

`window_group` : | a GtkWindowGroup
`window` : | the GtkWindow to add

### gtk_window_group_remove_window ()

    void                gtk_window_group_remove_window      (GtkWindowGroup *window_group,
                                                             GtkWindow *window);

Removes a window from a GtkWindowGroup.

`window_group` : | a GtkWindowGroup
`window` : | the GtkWindow to remove

### gtk_window_group_list_windows ()

    GList *             gtk_window_group_list_windows       (GtkWindowGroup *window_group);

Returns a list of the GtkWindows that belong to `window_group`.

`window_group` : | a GtkWindowGroup
Returns : | A newly-allocated list of windows inside the group. [element-type GtkWindow][transfer container]

Since 2.14

### gtk_window_group_get_current_grab ()

    GtkWidget *         gtk_window_group_get_current_grab   (GtkWindowGroup *window_group);

Gets the current grab widget of the given group, see `gtk_grab_add()`.

`window_group` : | a GtkWindowGroup
Returns : | the current grab widget of the group. [transfer none]

Since 2.22

### gtk_window_group_get_current_device_grab ()

    GtkWidget *         gtk_window_group_get_current_device_grab
                                                            (GtkWindowGroup *window_group,
                                                             GdkDevice *device);

Returns the current grab widget for `device`, or `NULL` if none.

`window_group` : | a GtkWindowGroup
`device` : | a GdkDevice
Returns : | The grab widget, or `NULL`. [transfer none]
