Device

addOnChanged gulong addOnChanged(void delegate(Device) dlg, ConnectFlags connectFlags): The ::changed signal is emitted either when the #GdkDevice 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.
addOnToolChanged gulong addOnToolChanged(void delegate(DeviceTool, Device) dlg, ConnectFlags connectFlags): The ::tool-changed signal is emitted on pen/eraser #GdkDevices whenever tools enter or leave proximity.
getAssociatedDevice Device getAssociatedDevice(): Returns the associated device to @device, if @device is of type %GDK_DEVICE_TYPE_MASTER, it will return the paired pointer or keyboard.
getAxes GdkAxisFlags getAxes(): Returns the axes currently available on the device.
getAxis bool getAxis(double[] axes, GdkAxisUse use, double value): Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis use.
getAxisUse GdkAxisUse getAxisUse(uint index): Returns the axis use for @index_.
getAxisValue bool getAxisValue(double[] axes, GdkAtom axisLabel, double value): 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 gdk_device_list_axes()
getDeviceStruct GdkDevice* getDeviceStruct(bool transferOwnership): Get the main Gtk struct
getDeviceType GdkDeviceType getDeviceType(): Returns the device type for @device.
getDisplay Display getDisplay(): Returns the #GdkDisplay to which @device pertains.
getHasCursor bool getHasCursor(): Determines whether the pointer follows device motion. This is not meaningful for keyboard devices, which don't have a pointer.
getHistory bool getHistory(Window window, uint start, uint stop, GdkTimeCoord*[] events): 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.)
getKey bool getKey(uint index, uint keyval, GdkModifierType modifiers): If @index_ has a valid keyval, this function will return %TRUE and fill in @keyval and @modifiers with the keyval settings.
getLastEventWindow Window getLastEventWindow(): 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.
getMode GdkInputMode getMode(): Determines the mode of the device.
getNAxes int getNAxes(): Returns the number of axes the device currently has.
getNKeys int getNKeys(): Returns the number of keys the device currently has.
getName string getName(): Determines the name of the device.
getPosition void getPosition(Screen screen, int x, int y): 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().
getPositionDouble void getPositionDouble(Screen screen, double x, double y): 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().
getProductId string getProductId(): 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.
getSeat Seat getSeat(): Returns the #GdkSeat the device belongs to.
getSource GdkInputSource getSource(): Determines the type of the device.
getState void getState(Window window, double[] axes, GdkModifierType mask): 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 gdk_device_grab().
getStruct void* getStruct(): the main Gtk struct as a void*
getVendorId string getVendorId(): 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.
getWindowAtPosition Window getWindowAtPosition(int winX, int winY): 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).
getWindowAtPositionDouble Window getWindowAtPositionDouble(double winX, double winY): 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).
grab GdkGrabStatus grab(Window window, GdkGrabOwnership grabOwnership, bool ownerEvents, GdkEventMask eventMask, Cursor cursor, uint time): 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.
listAxes ListG listAxes(): Returns a #GList of #GdkAtoms, containing the labels for the axes that @device currently has.
listSlaveDevices ListG listSlaveDevices(): 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
setAxisUse void setAxisUse(uint index, GdkAxisUse use): Specifies how an axis of a device is used.
setKey void setKey(uint index, uint keyval, GdkModifierType modifiers): Specifies the X key event to generate when a macro button of a device is pressed.
setMode bool setMode(GdkInputMode mode): 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.
ungrab void ungrab(uint time): Release any grab on @device.
warp void warp(Screen screen, int x, int y): 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.

Static functions

addOnNotify gulong addOnNotify(void delegate(ParamSpec, ObjectG) dlg, string property, ConnectFlags connectFlags): 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.
getType GType getType()
compatControl size_t compatControl(size_t what, void* data)
interfaceFindProperty ParamSpec interfaceFindProperty(TypeInterface gIface, string propertyName): 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().
interfaceInstallProperty void interfaceInstallProperty(TypeInterface gIface, ParamSpec pspec): 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.
interfaceListProperties ParamSpec[] interfaceListProperties(TypeInterface gIface): 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().
addToggleRef void addToggleRef(GToggleNotify notify, void* data): 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.
addWeakPointer void addWeakPointer(void* weakPointerLocation): 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.
bindProperty Binding bindProperty(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags): 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:
bindPropertyFull Binding bindPropertyFull(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, GBindingTransformFunc transformTo, GBindingTransformFunc transformFrom, void* userData, GDestroyNotify notify): Complete version of g_object_bind_property().
bindPropertyWithClosures Binding bindPropertyWithClosures(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, Closure transformTo, Closure transformFrom): 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.
dupData void* dupData(string key, GDuplicateFunc dupFunc, void* userData): 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.
dupQdata void* dupQdata(GQuark quark, GDuplicateFunc dupFunc, void* userData): 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.
forceFloating void forceFloating(): 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().
freezeNotify void freezeNotify(): 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.
getData void* getData(string key): Gets a named field from the objects table of associations (see g_object_set_data()).
getProperty void getProperty(string propertyName, Value value): Gets a property of an object.
getQdata void* getQdata(GQuark quark): This function gets back user data pointers stored via g_object_set_qdata().
getValist void getValist(string firstPropertyName, void* varArgs): Gets properties of an object.
getv void getv(string[] names, Value[] values): 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.
isFloating bool isFloating(): Checks whether @object has a floating[floating-ref] reference.
notify void notify(string propertyName): Emits a "notify" signal for the property @property_name on @object.
notifyByPspec void notifyByPspec(ParamSpec pspec): Emits a "notify" signal for the property specified by @pspec on @object.
doref alias doref = ref_: Undocumented in source.
ref_ ObjectG ref_(): Increases the reference count of @object.
refSink ObjectG refSink(): Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.
removeToggleRef void removeToggleRef(GToggleNotify notify, void* data): Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
removeWeakPointer void removeWeakPointer(void* weakPointerLocation): 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().
replaceData bool replaceData(string key, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify oldDestroy): Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.
replaceQdata bool replaceQdata(GQuark quark, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify oldDestroy): Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.
runDispose void runDispose(): Releases all references to other objects. This can be used to break reference cycles.
setData void setData(string key, void* data): Each object carries around a table of associations from strings to pointers. This function lets you set an association.
setDataFull void setDataFull(string key, void* data, GDestroyNotify destroy): 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.
setProperty void setProperty(string propertyName, Value value): Sets a property on an object.
setQdata void setQdata(GQuark quark, void* data): 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.
setQdataFull void setQdataFull(GQuark quark, void* data, GDestroyNotify destroy): 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.
setValist void setValist(string firstPropertyName, void* varArgs): Sets properties on an object.
setv void setv(string[] names, Value[] values): 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.
stealData void* stealData(string key): Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
stealQdata void* stealQdata(GQuark quark): 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"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);
thawNotify void thawNotify(): 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.
unref void unref(): Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
watchClosure void watchClosure(Closure closure): 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.
weakRef void weakRef(GWeakNotify notify, void* 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).
weakUnref void weakUnref(GWeakNotify notify, void* data): Removes a weak reference callback to an object.
clearObject void clearObject(ObjectG objectPtr): Clears a reference to a #GObject.
