GestureSingleProtocol
public protocol GestureSingleProtocol : GestureProtocol
GtkGestureSingle
is a subclass of GtkGesture
, optimized (although
not restricted) for dealing with mouse and single-touch gestures. Under
interaction, these gestures stick to the first interacting sequence, which
is accessible through gtk_gesture_single_get_current_sequence()
while the
gesture is being interacted with.
By default gestures react to both GDK_BUTTON_PRIMARY
and touch
events, gtk_gesture_single_set_touch_only()
can be used to change the
touch behavior. Callers may also specify a different mouse button number
to interact with through gtk_gesture_single_set_button()
, or react to any
mouse button by setting 0. While the gesture is active, the button being
currently pressed can be known through gtk_gesture_single_get_current_button()
.
The GestureSingleProtocol
protocol exposes the methods and properties of an underlying GtkGestureSingle
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see GestureSingle
.
Alternatively, use GestureSingleRef
as a lighweight, unowned
reference if you already have an instance you just want to use.

Untyped pointer to the underlying
GtkGestureSingle
instance.Declaration
Swift
var ptr: UnsafeMutableRawPointer! { get }
-
gesture_single_ptr
Default implementationTyped pointer to the underlying
GtkGestureSingle
instance.Default Implementation
Return the stored, untyped pointer as a typed pointer to the
GtkGestureSingle
instance.Declaration
Swift
var gesture_single_ptr: UnsafeMutablePointer<GtkGestureSingle>! { get }

Required Initialiser for types conforming to
GestureSingleProtocol
Declaration
Swift
init(raw: UnsafeMutableRawPointer)

get(property:
Extension method) Get the value of a GestureSingle property
Declaration
Swift
@inlinable func get(property: GestureSinglePropertyName) -> GLibObject.Value
Parameters
property
the property to get the value for
Return Value
the value of the named property
-
set(property:
Extension methodvalue: ) Set the value of a GestureSingle property. Note that this will only have an effect on properties that are writable and not construct-only!
Declaration
Swift
@inlinable func set(property: GestureSinglePropertyName, value v: GLibObject.Value)
Parameters
property
the property to get the value for
Return Value
the value of the named property
-
getButton()
Extension methodReturns the button number
gesture
listens for, or 0 ifgesture
reacts to any button press.Declaration
Swift
@inlinable func getButton() -> Int
-
getCurrentButton()
Extension methodReturns the button number currently interacting with
gesture
, or 0 if there is none.Declaration
Swift
@inlinable func getCurrentButton() -> Int
-
getCurrentSequence()
Extension methodReturns the event sequence currently interacting with
gesture
. This is only meaningful ifgtk_gesture_is_active()
returnstrue
.Declaration
Swift
@inlinable func getCurrentSequence() -> Gdk.EventSequenceRef!
-
getExclusive()
Extension methodGets whether a gesture is exclusive. For more information, see
gtk_gesture_single_set_exclusive()
.Declaration
Swift
@inlinable func getExclusive() -> Bool
-
getTouchOnly()
Extension methodReturns
true
if the gesture is only triggered by touch events.Declaration
Swift
@inlinable func getTouchOnly() -> Bool
-
set(button:
Extension method) Sets the button number
gesture
listens to. If non-0, every button press from a different button number will be ignored. Touch events implicitly match with button 1.Declaration
Swift
@inlinable func set(button: Int)
-
set(exclusive:
Extension method) Sets whether
gesture
is exclusive. An exclusive gesture will only handle pointer and “pointer emulated” touch events, so at any given time, there is only one sequence able to interact with those.Declaration
Swift
@inlinable func set(exclusive: Bool)
-
set(touchOnly:
Extension method) If
touch_only
istrue
,gesture
will only handle events of typeGDK_TOUCH_BEGIN
,GDK_TOUCH_UPDATE
orGDK_TOUCH_END
. Iffalse
, mouse events will be handled too.Declaration
Swift
@inlinable func set(touchOnly: Bool)
-
button
Extension methodMouse button number to listen to, or 0 to listen for any button.
Declaration
Swift
@inlinable var button: Int { get nonmutating set }
-
currentButton
Extension methodReturns the button number currently interacting with
gesture
, or 0 if there is none.Declaration
Swift
@inlinable var currentButton: Int { get }
-
currentSequence
Extension methodReturns the event sequence currently interacting with
gesture
. This is only meaningful ifgtk_gesture_is_active()
returnstrue
.Declaration
Swift
@inlinable var currentSequence: Gdk.EventSequenceRef! { get }
-
exclusive
Extension methodWhether the gesture is exclusive. Exclusive gestures only listen to pointer and pointer emulated events.
Declaration
Swift
@inlinable var exclusive: Bool { get nonmutating set }
-
touchOnly
Extension methodReturns
true
if the gesture is only triggered by touch events.Declaration
Swift
@inlinable var touchOnly: Bool { get nonmutating set }
