class: GestureLongPressCancelledCallback

[221:7] extends: object

Generated low-level callback wrapper for GIR callback cancelled.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• GestureLongPressCancelledCallback (callback Fn, UserData = null)

  Creates one native callback wrapper. The wrapper owns a trampoline that converts native pointers into generated wrapper objects before invoking Fn.

  • @p Fn is the Aussom callback implementation.
  • @p UserData is retained and passed through to Fn on each invocation when provided.

• trampoline (nativeSelf, nativeUserData)

  Internal trampoline. Converts native pointer arguments into generated wrapper instances, then invokes the user's callback.

• callback ()

  Returns the wrapped NativeCallback.

• handle ()

  Returns the callback as a NativeHandle.

• close ()

  Closes the underlying NativeCallback.

• isClosed ()

  Returns true when the callback has been closed.

class: GestureLongPress

[19:7] extends: object

Recognizes long press gestures. This gesture is also known as “Press and Hold”. When the timeout is exceeded, the gesture is triggering the [signal@Gtk.GestureLongPress::pressed] signal. If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the [signal@Gtk.GestureLongPress::cancelled] signal will be emitted. How long the timeout is before the ::pressed signal gets emitted is determined by the [property@Gtk.Settings:gtk-long-press-time] setting. It can be modified by the [property@Gtk.GestureLongPress:delay-factor] property.

Members

• handleObj
• lib
• retainedCallbacks
• signalHandlerNames
• signalSetterHandlers

Methods

• GestureLongPress ()

  Returns a newly created GtkGesture that recognizes long presses.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asGestureSingle ()

  Wraps this handle as GestureSingle.

  • @r A GestureSingle object.

• connectSignal (string Name, CallbackObj)

  Connects one generated callback wrapper to a named signal.

  • @p Name is the signal name.
  • @p CallbackObj is the generated callback wrapper to connect.
  • @r The connected handler id.

• disconnectSignalHandler (int HandlerId)

  Disconnects one retained signal handler id.

  • @p HandlerId is the signal handler id to disconnect.
  • @r None.

• setOnCancelled (callback Fn, UserData = null)

  Emitted whenever a press moved too far, or was released before [signal@Gtk.GestureLongPress::pressed] happened.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (GestureLongPress Self).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• setOnPressed (callback Fn, UserData = null)

  Emitted whenever a press goes unmoved/unreleased longer than what the GTK defaults tell.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (GestureLongPress Self, double X, double Y).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setDelayfactor (double Value)

  Factor by which to modify the default timeout.

  • @p Value is the new property value.
  • @r None.

• get_delay_factor ()

  Returns the delay factor.

• set_delay_factor (double delay_factor)

  Applies the given delay factor. The default long press time will be multiplied by this value. Valid values are in the range [0.5..2.0].

  • @p delay_factor is The delay factor to apply.
  • @r None.

class: GestureLongPressMeta

[361:14] static extends: object

Generated metadata helpers for GestureLongPress class surfaces.

Methods

• properties ()

  Returns property metadata for GestureLongPress.

  • @r A list.

• signals ()

  Returns signal metadata for GestureLongPress.

  • @r A list.
