low_memory_warning
Description:
Emitted when the system is running low on free memory.
The signal handler should then take the appropriate action depending on the warning level. See the MemoryMonitorWarningLevel documentation for details.
Since the [iface@Gio.MemoryMonitor] is a singleton, this signal will be emitted in the [func@GLib.MainContext.default][global-default main context].
Parameters:
| level |
