From 7b138e5ef0f679c9bb0078019d7c9c63fef36273 Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Mon, 24 Sep 2018 20:54:57 +1000 Subject: Add CSD to border modes This replaces view.using_csd with a new border mode: B_CSD. This also removes sway_xdg_shell{_v6}_view.deco_mode and view->has_client_side_decorations as we can now get these from the border. You can use `border toggle` to cycle through the modes including CSD, or use `border csd` to set it directly. The client must support the xdg-decoration protocol, and the only client I know of that does is the example in wlroots. If the client switches from SSD to CSD without us expecting it (via the server-decoration protocol), we stash the previous border type into view.saved_border so we can restore it if the client returns to SSD. I haven't found a way to test this though. --- include/sway/server.h | 5 +++++ include/sway/tree/container.h | 2 +- include/sway/tree/view.h | 21 +++++++++++++++------ include/sway/xdg_decoration.h | 19 +++++++++++++++++++ 4 files changed, 40 insertions(+), 7 deletions(-) create mode 100644 include/sway/xdg_decoration.h (limited to 'include/sway') diff --git a/include/sway/server.h b/include/sway/server.h index 5dabb61f..3e1cbb33 100644 --- a/include/sway/server.h +++ b/include/sway/server.h @@ -54,6 +54,10 @@ struct sway_server { struct wl_listener server_decoration;

I was under the impression the client could ignore the server's preference and set whatever decoration they like using this protocol, but I don't think that's right. * Adds a listener for the xdg-decoration request_mode signal. The protocol states that the server should respond to this with its preference. We'll always respond with SSD here. * Makes it so tiled views which use CSD will still have sway decorations rendered. To do this, using_csd had to be added back to the view struct, and the border is changed when floating or unfloating a view. --- include/sway/tree/view.h | 11 +++++++++++ include/sway/xdg_decoration.h | 2 +- sway/commands/border.c | 45 +++++++++++++++++++++++++++++++++++++------ sway/tree/container.c | 6 ++++++ sway/tree/view.c | 8 +++++++- sway/xdg_decoration.c | 30 ++++++++--------------------- 6 files changed, 72 insertions(+), 30 deletions(-) (limited to 'include/sway') diff --git a/include/sway/tree/view.h b/include/sway/tree/view.h index e7aaffd7..2c7b4c2b 100644 --- a/include/sway/tree/view.h +++ b/include/sway/tree/view.h @@ -76,8 +76,19 @@ struct sway_view { int natural_width, natural_height; char *title_format; + + // Our border types are B_NONE, B_PIXEL, B_NORMAL and B_CSD.
