From 2dcbb8d20d644bebed6307192f21d7c3bcf26845 Mon Sep 17 00:00:00 2001 From: Sergi Granell Date: Fri, 24 Mar 2017 20:48:01 +0100 Subject: [PATCH] compositor-wayland: Refactor struct wayland_output::name usage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit struct wayland_output::name was used but never initialized. Also zxdg_toplevel_v6_set_title was only called for windowed outputs, and some compositors let you see the client's name even when it is fullscreen (GNOME Shell's Activities menu for example). So rename struct wayland_output::name to struct wayland_output::title and precompute it on wayland_output_create_common(), so it can be later used on xdg's set_title and frame_create. v2: Move zxdg_toplevel_v6_set_title() before the wl_surface_commit() as per Quentin Glidic's suggestion.
