Description

Extends the Icon interface and adds the ability to load icons from streams.

Synopsis

newtype LoadableIcon = LoadableIcon (ManagedPtr LoadableIcon)
noLoadableIcon :: Maybe LoadableIcon
class GObject o => IsLoadableIcon o
toLoadableIcon :: (MonadIO m, IsLoadableIcon o) => o -> m LoadableIcon
loadableIconLoad :: (HasCallStack, MonadIO m, IsLoadableIcon a, IsCancellable b) => a -> Int32 -> Maybe b -> m (InputStream, Text)
loadableIconLoadAsync :: (HasCallStack, MonadIO m, IsLoadableIcon a, IsCancellable b) => a -> Int32 -> Maybe b -> Maybe AsyncReadyCallback -> m ()
loadableIconLoadFinish :: (HasCallStack, MonadIO m, IsLoadableIcon a, IsAsyncResult b) => a -> b -> m (InputStream, Text)

noLoadableIcon :: Maybe LoadableIcon Source #

A convenience alias for Nothing :: Maybe LoadableIcon.

class GObject o => IsLoadableIcon o Source #

Type class for types which can be safely cast to LoadableIcon, for instance with toLoadableIcon.

toLoadableIcon :: (MonadIO m, IsLoadableIcon o) => o -> m LoadableIcon Source #

Cast to LoadableIcon, for types for which this is known to be safe. For general casts, use castTo.

Methods

load

loadableIconLoad Source #

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)	Returns: a `InputStream` to read the icon from. (Can throw `GError`)

Loads a loadable icon. For the asynchronous version of this function, see loadableIconLoadAsync.

loadAsync

loadableIconLoadAsync Source #

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.
-> Maybe AsyncReadyCallback	`callback`: a `AsyncReadyCallback` to call when the request is satisfied
-> m ()

Loads an icon asynchronously. To finish this function, see loadableIconLoadFinish. For the synchronous, blocking version of this function, see loadableIconLoad.

loadFinish

loadableIconLoadFinish Source #

Arguments

:: (HasCallStack, MonadIO m, IsLoadableIcon a, IsAsyncResult b)
=> a	`icon`: a `LoadableIcon`.
-> b	`res`: a `AsyncResult`.
-> m (InputStream, Text)	Returns: a `InputStream` to read the icon from. (Can throw `GError`)

Finishes an asynchronous icon load started in loadableIconLoadAsync.
