Signal
GioAppLaunchContext::launched
since: 2.36
Declaration
void
launched (
GAppLaunchContext* self,
GAppInfo* info,
GVariant* platform_data,
gpointer user_data
)
Description
The GAppLaunchContext::launched signal is emitted when a GAppInfo is successfully launched.
Because a launch operation may involve spawning multiple instances of the target application, you should expect this signal to be emitted multiple times, one time for each spawned instance.
The platform_data is an GVariant dictionary mapping
strings to variants (ie a{sv}), which contains additional,
platform-specific data about this launch. On UNIX, at least the
pid and startup-notification-id keys will be present.
Since 2.72 the pid may be 0 if the process id wasn’t known (for
example if the process was launched via D-Bus). The pid may not be
set at all in subsequent releases.
On Windows, pid is guaranteed to be valid only for the duration of the
GAppLaunchContext::launched signal emission; after the signal is emitted,
GLib will call g_spawn_close_pid(). If you need to keep the GPid after the
signal has been emitted, then you can duplicate pid using DuplicateHandle().
