/**
* GtkUriLauncher:
*
* A `GtkUriLauncher` object collects the arguments that are needed to open a uri
* with an application.
*
* Depending on system configuration, user preferences and available APIs, this
* may or may not show an app chooser dialog or launch the default application
* right away.
*
* The operation is started with the [method@Gtk.UriLauncher.launch] function.
* This API follows the GIO async pattern, and the result can be obtained by
* calling [method@Gtk.UriLauncher.launch_finish].
*
* To launch a file, use [class@Gtk.FileLauncher].
*
* Since: 4.10
