Sets our main struct and passes it to the parent class.
The ::changed signal is emitted either when the gdk.Device has changed the number of either axes or keys. For example In X this will normally happen when the slave device routing events through the master device changes (for example, user switches from the USB mouse to a tablet), in that case the master device will change to reflect the new slave device axes and keys.
The ::tool-changed signal is emitted on pen/eraser gdk.Devices whenever tools enter or leave proximity.
Returns the associated device to device, if device is of type GDK_DEVICE_TYPE_MASTER, it will return the paired pointer or keyboard.
Returns the axes currently available on the device.
Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis use.
Returns the axis use for index_.
Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis label, as returned by Device.listAxes
Get the main Gtk struct
Returns the device type for device.
Returns the gdk.Display to which device pertains.
Determines whether the pointer follows device motion. This is not meaningful for keyboard devices, which don't have a pointer.
Obtains the motion history for a pointer device; given a starting and ending timestamp, return all events in the motion history for the device in the given range of time. Some windowing systems do not support motion history, in which case, FALSE will be returned. (This is not distinguishable from the case where motion history is supported and no events were found.)
If index_ has a valid keyval, this function will return TRUE and fill in keyval and modifiers with the keyval settings.
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.
Determines the mode of the device.
Returns the number of axes the device currently has.
Returns the number of keys the device currently has.
Determines the name of the device.
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 Device.grab.
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 Device.grab.
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 Device.getVendorId for more information.
Returns the gdk.Seat the device belongs to.
Determines the type of the device.
Gets the current state of a pointer device relative to window. 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 Device.grab.
the main Gtk struct as a void*
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.
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).
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).
Grabs the device so that all events coming from this device are passed to this application until the device is ungrabbed with Device.ungrab, or the window becomes unviewable. This overrides any previous grab on the device by this client.
If the device if of type GDK_DEVICE_TYPE_MASTER, it will return the list of slave devices attached to it, otherwise it will return NULL
Specifies how an axis of a device is used.
Specifies the X key event to generate when a macro button of a device is pressed.
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.
Release any grab on device.
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.
Determines information about the current keyboard grab. This is not public API and must not be used by applications.

Gets a D Object from the objects table of associations.
The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.
Find the gobject.ParamSpec 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().
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 ObjectClass.overrideProperty 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.
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().
Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.
Adds a weak reference from weak_pointer to object to indicate that the pointer located at weak_pointer_location is only valid during the lifetime of object. When the object is finalized, weak_pointer will be set to NULL.
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:
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.
This is a variant of g_object_get_data() which returns a 'duplicate' of the value. dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
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 notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see g_object_set_data()).
Gets a property of an object. value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using Value.init.
This function gets back user data pointers stored via g_object_set_qdata().
Gets properties of an object.
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.
Checks whether object has a floating[floating-ref] reference.
Emits a "notify" signal for the property property_name on object.
Emits a "notify" signal for the property specified by pspec on object.
Increases the reference count of object.
Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
Removes a weak reference from object that was previously added using g_object_add_weak_pointer(). The weak_pointer_location has to match the one used with g_object_add_weak_pointer().
Compares the user data for the key key on object with oldval, and if they are the same, replaces oldval with newval.
Compares the user data for the key quark on object with oldval, and if they are the same, replaces oldval with newval.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.
Sets a property on an object.
This sets an opaque, named pointer on an object. The name is specified through a GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the object with g_object_get_qdata() until the object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored.
This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with data as argument when the object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same quark.
Sets properties on an object.
Sets n_properties properties for an object. Properties to be set will be taken from values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via g_object_set_qdata() 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:
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.
Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
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 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.
Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback to an object.
Clears a reference to a GObject
