From cab1352801b62d1b8a12ca1c995cb24445ce4bc9 Mon Sep 17 00:00:00 2001 From: Drew DeVault Date: Wed, 28 Mar 2018 23:04:20 -0400 Subject: Start port of swaybar to layer shell This starts up the event loop and wayland display and shims out the basic top level rendering concepts. Also includes some changes to incorporate pango into the 1.x codebase properly. --- swaybar/tray/sni.c | 481 ----------------------------------------------------- 1 file changed, 481 deletions(-) delete mode 100644 swaybar/tray/sni.c (limited to 'swaybar/tray/sni.c') diff --git a/swaybar/tray/sni.c b/swaybar/tray/sni.c deleted file mode 100644 index c9d00657..00000000 --- a/swaybar/tray/sni.c +++ /dev/null @@ -1,481 +0,0 @@ -#define _XOPEN_SOURCE 500 -#include -#include -#include -#include -#include -#include -#include -#include -#include "swaybar/tray/dbus.h" -#include "swaybar/tray/sni.h" -#include "swaybar/tray/icon.h" -#include "swaybar/bar.h" -#include "client/cairo.h" -#include "log.h" - -// Not sure what this is but cairo needs it. -static const cairo_user_data_key_t cairo_user_data_key;
