Methods

Overloaded methods

new

volumeButtonNew

Arguments

:: (HasCallStack, MonadIO m)

=> m VolumeButton

Properties

useSymbolic

Whether to use symbolic icons as the icons. Note that if the symbolic icons are not available in your installed theme, then the normal (potentially colorful) icons will be used.

Since: 3.0

constructVolumeButtonUseSymbolic :: IsVolumeButton o => Bool -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “use-symbolic” property. This is rarely needed directly, but it is used by new.

getVolumeButtonUseSymbolic :: (MonadIO m, IsVolumeButton o) => o -> m Bool

Get the value of the “use-symbolic” property. When overloading is enabled, this is equivalent to

get volumeButton #useSymbolic

setVolumeButtonUseSymbolic :: (MonadIO m, IsVolumeButton o) => o -> Bool -> m ()

Set the value of the “use-symbolic” property. When overloading is enabled, this is equivalent to

set volumeButton [ #useSymbolic := value ]
