Synopsis

Exported types

newtype LoadableIcon Source #

Memory-managed wrapper type.

Instances
GObject LoadableIcon Source #

Defined in GI.Gio.Interfaces.LoadableIcon

Methods

gobjectType :: IO GType #

HasParentTypes LoadableIcon Source # 
Instance details

Defined in GI.Gio.Interfaces.LoadableIcon

type ParentTypes LoadableIcon Source # 
Instance details

Defined in GI.Gio.Interfaces.LoadableIcon

type ParentTypes LoadableIcon = Icon ': (Object ': ([] :: [Type]))

class (GObject o, IsDescendantOf LoadableIcon o) => IsLoadableIcon o Source #

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

Instances
(GObject o, IsDescendantOf LoadableIcon o) => IsLoadableIcon o Source # 
Instance details

Defined in GI.Gio.Interfaces.LoadableIcon

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.
