appInfoLaunchDefaultForUri
fun appInfoLaunchDefaultForUri(uri: String, context: AppLaunchContext? = null): <Error class: unknown class><Boolean>
Utility function that launches the default application registered to handle the specified uri. Synchronous I/O is done on the uri to detect the type of the file if required.
The D-Bus–activated applications don't have to be started if your application terminates too soon after this function. To prevent this, use g_app_info_launch_default_for_uri_async() instead.
Return
true on success, false on error.
Parameters
uri
the uri to show
context
an optional #GAppLaunchContext
