SurfaceSignalName

public enum SurfaceSignalName : String, SignalNameProtocol

Undocumented

  • Emitted when surface starts being present on the monitor.

    Declaration

    Swift

    case enterMonitor = "enter-monitor"
  • Emitted when GDK receives an input event for surface.

    Declaration

    Swift

    case event = "event"
  • Emitted when the size of surface is changed, or when relayout should be performed.

    Surface size is reported in ”application pixels”, not ”device pixels” (see gdk_surface_get_scale_factor()).

    Declaration

    Swift

    case layout = "layout"
  • Emitted when surface stops being present on the monitor.

    Declaration

    Swift

    case leaveMonitor = "leave-monitor"
  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this: (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                      G_CALLBACK (gtk_text_view_target_list_notify),
                      text_view)
    

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.

    Declaration

    Swift

    case notify = "notify"
  • Emitted when part of the surface needs to be redrawn.

    Declaration

    Swift

    case render = "render"
  • The mouse pointer for the GdkSurface.

    Declaration

    Swift

    case notifyCursor = "notify::cursor"
  • The GdkDisplay connection of the surface.

    Declaration

    Swift

    case notifyDisplay = "notify::display"
  • The GdkFrameClock of the surface.

    Declaration

    Swift

    case notifyFrameClock = "notify::frame-clock"
  • The height of the surface, in pixels.

    Declaration

    Swift

    case notifyHeight = "notify::height"
  • Whether the surface is mapped.

    Declaration

    Swift

    case notifyMapped = "notify::mapped"
  • The scale factor of the surface.

    Declaration

    Swift

    case notifyScaleFactor = "notify::scale-factor"
  • The width of the surface in pixels.

    Declaration

    Swift

    case notifyWidth = "notify::width"
