GI.Gio.Interfaces.DebugController

Description

GDebugController is an interface to expose control of debugging features and debug output.

It is implemented on Linux using DebugControllerDBus, which exposes a D-Bus interface to allow authenticated peers to control debug features in this process.

Whether debug output is enabled is exposed as DebugController:debug-enabled. This controls logSetDebugEnabled by default. Application code may connect to the Object::notify signal for it to control other parts of its debug infrastructure as necessary.

If your application or service is using the default GLib log writer function, creating one of the built-in implementations of GDebugController should be all that’s needed to dynamically enable or disable debug output.

constructDebugControllerDebugEnabled :: (IsDebugController o, MonadIO m) => Bool -> m (GValueConstruct o) Source #

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

getDebugControllerDebugEnabled :: (MonadIO m, IsDebugController o) => o -> m Bool Source #

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

get debugController #debugEnabled

setDebugControllerDebugEnabled :: (MonadIO m, IsDebugController o) => o -> Bool -> m () Source #

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

set debugController [ #debugEnabled := value ]
