struct Gio::Settings::ChangedSignal

• Gio::Settings::ChangedSignal
• GObject::Signal
• Struct
• Value

Overview

The "changed" signal is emitted when a key has potentially changed. You should call one of the g_settings_get() calls to check the new value.

This signal supports detailed connections. You can connect to the detailed signal "changed::x" in order to only receive callbacks when key "x" changes.

Note that @settings only emits this signal if you have read @key at least once while a signal handler was already connected for @key.

Defined in:

lib/gi-crystal/src/auto/gio-2.0/settings.cr
