#GdkDevicePad is an interface implemented by devices of type %GDK_SOURCE_TABLET_PAD, it allows querying the features provided by the pad device.

Tablet pads may contain one or more groups, each containing a subset of the buttons/rings/strips available. gdk_device_pad_get_n_groups() can be used to obtain the number of groups, gdk_device_pad_get_n_features() and gdk_device_pad_get_feature_group() can be combined to find out the number of buttons/rings/strips the device has, and how are they grouped.

Each of those groups have different modes, which may be used to map each individual pad feature to multiple actions. Only one mode is effective (current) for each given group, different groups may have different current modes. The number of available modes in a group can be found out through gdk_device_pad_get_group_n_modes(), and the current mode for a given group will be notified through the #GdkEventPadGroupMode event.

Methods

  • 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

    • source_property: string

      the property on source to bind

      the target #GObject

    • target_property: 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.

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transform_to: TClosure<any, any>

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

    • transform_from: TClosure<any, any>

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

    Returns Binding

  • force_floating(): 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

  • freeze_notify(): 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

  • Returns the associated device to device, if device is of type %GDK_DEVICE_TYPE_MASTER, it will return the paired pointer or keyboard.

    If device is of type %GDK_DEVICE_TYPE_SLAVE, it will return the master device to which device is attached to.

    If device is of type %GDK_DEVICE_TYPE_FLOATING, %NULL will be returned, as there is no associated device.

    Returns Gdk.Device

  • get_data(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 the group the given feature and idx belong to, or -1 if feature/index do not exist in pad.

    Parameters

    • feature: Gdk.DevicePadFeature

      the feature type to get the group from

    • feature_idx: number

      the index of the feature to get the group from

    Returns number

  • get_group_n_modes(group_idx: number): number
  • Returns the number of modes that group may have.

    Parameters

    • group_idx: number

      group to get the number of available modes from

    Returns number

  • get_has_cursor(): boolean
  • If index_ has a valid keyval, this function will return %TRUE and fill in keyval and modifiers with the keyval settings.

    Parameters

    • index_: number

      the index of the macro button to get.

    Returns [boolean, number, Gdk.ModifierType]

  • Gets information about which window the given pointer device is in, based on events that have been received so far from the display server. If another application has a pointer grab, or this application has a grab with owner_events = %FALSE, %NULL may be returned even if the pointer is physically over one of this application's windows.

    Returns Gdk.Window

  • get_n_axes(): number
  • get_n_groups(): number
  • Returns the number of groups this pad device has. Pads have at least one group. A pad group is a subcollection of buttons/strip/rings that is affected collectively by a same current mode.

    Returns number

  • get_n_keys(): number
  • get_name(): string
  • Gets the current location of device. As a slave device coordinates are those of its master pointer, This function may not be called on devices of type %GDK_DEVICE_TYPE_SLAVE, unless there is an ongoing grab on them, see gdk_device_grab().

    Returns [Gdk.Screen, number, number]

  • get_position_double(): [Gdk.Screen, number, number]
  • Gets the current location of device in double precision. As a slave device's coordinates are those of its master pointer, this function may not be called on devices of type %GDK_DEVICE_TYPE_SLAVE, unless there is an ongoing grab on them. See gdk_device_grab().

    Returns [Gdk.Screen, number, number]

  • get_product_id(): string
  • Returns the product ID of this device, or %NULL if this information couldn't be obtained. This ID is retrieved from the device, and is thus constant for it. See gdk_device_get_vendor_id() for more information.

    Returns string

  • get_property(property_name?: 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 property_name: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • get_qdata(quark: number): object
  • get_vendor_id(): string
  • Returns the vendor ID of this device, or %NULL if this information couldn't be obtained. This ID is retrieved from the device, and is thus constant for it.

    This function, together with gdk_device_get_product_id(), can be used to eg. compose #GSettings paths to store settings for this device.

     static GSettings *
    get_device_settings (GdkDevice *device)
    {
    const gchar *vendor, *product;
    GSettings *settings;
    GdkDevice *device;
    gchar *path;

    vendor = gdk_device_get_vendor_id (device);
    product = gdk_device_get_product_id (device);

    path = g_strdup_printf ("/org/example/app/devices/%s:%s/", vendor, product);
    settings = g_settings_new_with_path (DEVICE_SCHEMA, path);
    g_free (path);

    return settings;
    }

    Returns string

  • get_window_at_position(): [Gdk.Window, number, number]
  • Obtains the window underneath device, returning the location of the device in win_x and win_y. Returns %NULL if the window tree under device is not known to GDK (for example, belongs to another application).

    As a slave device coordinates are those of its master pointer, This function may not be called on devices of type %GDK_DEVICE_TYPE_SLAVE, unless there is an ongoing grab on them, see gdk_device_grab().

    Returns [Gdk.Window, number, number]

  • get_window_at_position_double(): [Gdk.Window, number, number]
  • Obtains the window underneath device, returning the location of the device in win_x and win_y in double precision. Returns %NULL if the window tree under device is not known to GDK (for example, belongs to another application).

    As a slave device coordinates are those of its master pointer, This function may not be called on devices of type %GDK_DEVICE_TYPE_SLAVE, unless there is an ongoing grab on them, see gdk_device_grab().

    Returns [Gdk.Window, number, number]

  • 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

  • Grabs the device so that all events coming from this device are passed to this application until the device is ungrabbed with gdk_device_ungrab(), or the window becomes unviewable. This overrides any previous grab on the device by this client.

    Note that device and window need to be on the same display.

    Device grabs are used for operations which need complete control over the given device events (either pointer or keyboard). For example in GTK+ this is used for Drag and Drop operations, popup menus and such.

    Note that if the event mask of an X window has selected both button press and button release events, then a button press event will cause an automatic pointer grab until the button is released. X does this automatically since most applications expect to receive button press and release events in pairs. It is equivalent to a pointer grab on the window with owner_events set to %TRUE.

    If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the #GdkEventGrabBroken events that are emitted when the grab ends unvoluntarily.

    Parameters

    • window: Gdk.Window

      the #GdkWindow which will own the grab (the grab window)

    • grab_ownership: GrabOwnership

      specifies the grab ownership.

    • owner_events: boolean

      if %FALSE then all device events are reported with respect to window and are only reported if selected by event_mask. If %TRUE then pointer events for this application are reported as normal, but pointer events outside this application are reported with respect to window and only if selected by event_mask. In either mode, unreported events are discarded.

    • event_mask: Gdk.EventMask

      specifies the event mask, which is used in accordance with owner_events.

    • cursor: Gdk.Cursor

      the cursor to display while the grab is active if the device is a pointer. If this is %NULL then the normal cursors are used for window and its descendants, and the cursor for window is used elsewhere.

    • time_: number

      the timestamp of the event which led to this pointer grab. This usually comes from the #GdkEvent struct, though %GDK_CURRENT_TIME can be used if the time isn’t known.

    Returns Gdk.GrabStatus

  • is_floating(): boolean
  • notify(property_name: 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

    • 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.:

      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

  • 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

  • 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

  • run_dispose(): 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_axis_use(index_: number, use: Gdk.AxisUse): void
  • set_data(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

  • Specifies the X key event to generate when a macro button of a device is pressed.

    Parameters

    • index_: number

      the index of the macro button to set

    • keyval: number

      the keyval to generate

    • modifiers: Gdk.ModifierType

      the modifiers to set

    Returns void

  • Sets a the mode of an input device. The mode controls if the device is active and whether the device’s range is mapped to the entire screen or to a single window.

    Note: This is only meaningful for floating devices, master devices (and slaves connected to these) drive the pointer cursor, which is not limited by the input mode.

    Parameters

    Returns boolean

  • set_property(property_name: string, value?: any): void
  • steal_data(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

  • steal_qdata(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

  • thaw_notify(): 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

  • ungrab(time_: number): 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

  • vfunc_constructed(): void
  • vfunc_dispatch_properties_changed(n_pspecs: number, pspecs: ParamSpec): void
  • vfunc_dispose(): void
  • vfunc_finalize(): void
  • vfunc_get_property(property_id: number, value?: any, pspec?: ParamSpec): 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.

    virtual

    Parameters

    Returns void

  • vfunc_set_property(property_id: number, value?: any, pspec?: ParamSpec): void
  • warp(screen: Gdk.Screen, x: number, y: number): void
  • Warps device in display to the point x,``y on the screen screen, unless the device is confined to a window by a grab, in which case it will be moved as far as allowed by the grab. Warping the pointer creates events as if the user had moved the mouse instantaneously to the destination.

    Note that the pointer should normally be under the control of the user. This function was added to cover some rare use cases like keyboard navigation support for the color picker in the #GtkColorSelectionDialog.

    Parameters

    • screen: Gdk.Screen

      the screen to warp device to.

    • x: number

      the X coordinate of the destination.

    • y: number

      the Y coordinate of the destination.

    Returns void

  • watch_closure(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

  • compat_control(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

    • g_iface: TypeInterface

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

    • property_name: 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

    • g_iface: 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

    • g_iface: TypeInterface

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

    Returns ParamSpec[]

  • 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

    • object_type: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
