Methods

load

loadableIconLoad

Arguments

:: (HasCallStack, MonadIO m, IsLoadableIcon a, IsCancellable b)

=> a

icon: a LoadableIcon.

-> Int32

size: an integer.

-> Maybe b

cancellable: optional Cancellable object, Nothing to ignore.

-> m (InputStream, Text)

:: (HasCallStack, MonadIO m, IsLoadableIcon a, IsCancellable b)

=> a

icon: a LoadableIcon.

-> Int32

size: an integer.

-> Maybe b

cancellable: optional Cancellable object, Nothing to ignore.

-> Maybe AsyncReadyCallback

callback: a AsyncReadyCallback to call when the request is satisfied

-> m ()
