struct Gio::Settings::WritableChangedSignal

Overview

The "writable-changed" signal is emitted when the writability of a key has potentially changed. You should call g_settings_is_writable() in order to determine the new status.

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

Defined in:

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