Type Aliases

The following type aliases are available globally.

  • The type of a function that can be registered with gdk_content_register_deserializer().

    When the function gets called to operate on content, it can call functions on the deserializer object to obtain the mime type, input stream, user data, etc. for its operation.

    Declaration

    Swift

    public typealias ContentDeserializeFunc = GdkContentDeserializeFunc

  • The type of a function that can be registered with gdk_content_register_serializer().

    When the function gets called to operate on content, it can call functions on the serializer object to obtain the mime type, output stream, user data, etc. for its operation.

    Declaration

    Swift

    public typealias ContentSerializeFunc = GdkContentSerializeFunc

  • Defines how device axes are interpreted by GTK.

    Note that the X and Y axes are not really needed; pointer devices report their location via the x/y members of events regardless. Whether X and Y are present as axes depends on the GDK backend.

    Declaration

    Swift

    public typealias AxisUse = GdkAxisUse

  • Specifies the crossing mode for enter and leave events.

    Declaration

    Swift

    public typealias CrossingMode = GdkCrossingMode

  • A pad feature.

    Declaration

    Swift

    public typealias DevicePadFeature = GdkDevicePadFeature
    Show on GitHub

  • Indicates the specific type of tool being used being a tablet. Such as an airbrush, pencil, etc.

    Declaration

    Swift

    public typealias DeviceToolType = GdkDeviceToolType

  • Used in GdkDrag to the reason of a cancelled DND operation.

    Declaration

    Swift

    public typealias DragCancelReason = GdkDragCancelReason
    Show on GitHub

  • Specifies the type of the event.

    Declaration

    Swift

    public typealias EventType = GdkEventType

  • Indicates which monitor a surface should span over when in fullscreen mode.

    Declaration

    Swift

    public typealias FullscreenMode = GdkFullscreenMode

  • Error enumeration for GdkGLContext.

    Declaration

    Swift

    public typealias GLError = GdkGLError
    Show on GitHub

  • Defines the reference point of a surface and is used in GdkPopupLayout.

    Declaration

    Swift

    public typealias Gravity = GdkGravity

  • An enumeration describing the type of an input device in general terms.

    Declaration

    Swift

    public typealias InputSource = GdkInputSource
    Show on GitHub

  • Describes how well an event matches a given keyval and modifiers.

    GdkKeyMatch values are returned by [methodGdk.KeyEvent.matches].

    Declaration

    Swift

    public typealias KeyMatch = GdkKeyMatch
    Show on GitHub

  • GdkMemoryFormat describes a format that bytes can have in memory.

    It describes formats by listing the contents of the memory passed to it. So GDK_MEMORY_A8R8G8B8 will be 1 byte (8 bits) of alpha, followed by a byte each of red, green and blue. It is not endian-dependent, so CAIRO_FORMAT_ARGB32 is represented by different GdkMemoryFormats on architectures with different endiannesses.

    Its naming is modelled after VkFormat (see https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.html`VkFormat` for details).

    Declaration

    Swift

    public typealias MemoryFormat = GdkMemoryFormat
    Show on GitHub

  • Specifies the kind of crossing for enter and leave events.

    See the X11 protocol specification of LeaveNotify for full details of crossing event generation.

    Declaration

    Swift

    public typealias NotifyType = GdkNotifyType
    Show on GitHub

  • Specifies the direction for scroll events.

    Declaration

    Swift

    public typealias ScrollDirection = GdkScrollDirection
    Show on GitHub

  • This enumeration describes how the red, green and blue components of physical pixels on an output device are laid out.

    Declaration

    Swift

    public typealias SubpixelLayout = GdkSubpixelLayout
    Show on GitHub

  • Determines a surface edge or corner.

    Declaration

    Swift

    public typealias SurfaceEdge = GdkSurfaceEdge

  • Specifies the current state of a touchpad gesture.

    All gestures are guaranteed to begin with an event with phase GDK_TOUCHPAD_GESTURE_PHASE_BEGIN, followed by 0 or several events with phase GDK_TOUCHPAD_GESTURE_PHASE_UPDATE.

    A finished gesture may have 2 possible outcomes, an event with phase GDK_TOUCHPAD_GESTURE_PHASE_END will be emitted when the gesture is considered successful, this should be used as the hint to perform any permanent changes.

    Cancelled gestures may be so for a variety of reasons, due to hardware or the compositor, or due to the gesture recognition layers hinting the gesture did not finish resolutely (eg. a 3rd finger being added during a pinch gesture). In these cases, the last event will report the phase GDK_TOUCHPAD_GESTURE_PHASE_CANCEL, this should be used as a hint to undo any visible/permanent changes that were done throughout the progress of the gesture.

    Declaration

    Swift

    public typealias TouchpadGesturePhase = GdkTouchpadGesturePhase
