class: PixbufModuleFillInfoFuncCallback

[13:7] extends: object

Defines the type of the function used to fill a #GdkPixbufFormat structure with information about a module.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• PixbufModuleFillInfoFuncCallback (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 (info)

  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: PixbufModuleLoadFuncCallback

[226:7] extends: object

Loads a file from a standard C file stream into a new GdkPixbuf. In case of error, this function should return NULL and set the error argument.
