class: EventControllerLegacy

[13:7] extends: object

Provides raw access to the event stream. It should only be used as a last resort if none of the other event controllers or gestures do the job.

Members

• handleObj
• lib
• retainedCallbacks
• signalHandlerNames
• signalSetterHandlers

Methods

• EventControllerLegacy ()

  Creates a new legacy event controller.

• 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.

• asEventController ()

  Wraps this handle as EventController.

  • @r A EventController 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.

• setOnEvent (callback Fn, UserData = null)

  Emitted for each GDK event delivered to @controller.

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

class: EventControllerLegacyEventCallback

[148:7] extends: object

Generated low-level callback wrapper for GIR callback event.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• EventControllerLegacyEventCallback (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, event, 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: EventControllerLegacyMeta

[219:14] static extends: object

Generated metadata helpers for EventControllerLegacy class surfaces.

Methods

• signals ()

  Returns signal metadata for EventControllerLegacy.

  • @r A list.
