class: EventControllerFocusEnterCallback

[200:7] extends: object

Generated low-level callback wrapper for GIR callback enter.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• EventControllerFocusEnterCallback (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: EventControllerFocus

[18:7] extends: object

Tracks keyboard focus. The event controller offers [signal@Gtk.EventControllerFocus::enter] and [signal@Gtk.EventControllerFocus::leave] signals, as well as [property@Gtk.EventControllerFocus:is-focus] and [property@Gtk.EventControllerFocus:contains-focus] properties which are updated to reflect focus changes inside the widget hierarchy that is rooted at the controllers widget.

Members

• handleObj
• lib
• retainedCallbacks
• signalHandlerNames
• signalSetterHandlers

Methods

• EventControllerFocus ()

  Creates a new event controller that will handle focus events.

• 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.

• setOnEnter (callback Fn, UserData = null)

  Emitted whenever the focus enters into the widget or one of its descendents. Note that this means you may not get an ::enter signal even though the widget becomes the focus location, in certain cases (such as when the focus moves from a descendent of the widget to the widget itself). If you are interested in these cases, you can monitor the [property@Gtk.EventControllerFocus:is-focus] property for changes.

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

• setOnLeave (callback Fn, UserData = null)

  Emitted whenever the focus leaves the widget hierarchy that is rooted at the widget that the controller is attached to. Note that this means you may not get a ::leave signal even though the focus moves away from the widget, in certain cases (such as when the focus moves from the widget to a descendent). If you are interested in these cases, you can monitor the [property@Gtk.EventControllerFocus:is-focus] property for changes.

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

• contains_focus ()

  Returns %TRUE if focus is within @self or one of its children.

• is_focus ()

  Returns %TRUE if focus is within @self, but not one of its children.

class: EventControllerFocusLeaveCallback

[270:7] extends: object

Generated low-level callback wrapper for GIR callback leave.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• EventControllerFocusLeaveCallback (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: EventControllerFocusMeta

[340:14] static extends: object

Generated metadata helpers for EventControllerFocus class surfaces.

Methods

• properties ()

  Returns property metadata for EventControllerFocus.

  • @r A list.

• signals ()

  Returns signal metadata for EventControllerFocus.

  • @r A list.
