From 7d1870c6f1c1dd14fe9fe13885021970f0cbdbe8 Mon Sep 17 00:00:00 2001 From: Dominique Martinet Date: Sat, 3 Mar 2018 17:03:19 +0100 Subject: move xwm.h out of include/wlr xwm.h was meant to be private, so move it to include/xwayland/xwm.h We had an ifdef WLR_HAS_XCB_ICCCM in xwayland.h which was easy to move to xwm, it is not safe to use the WLR_HAS_* in the public headers. I checked a few of our current users and none rely on xwm.h being public as expected (rootston, sway, hsroots) --- include/xwayland/xwm.h | 132 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 132 insertions(+) create mode 100644 include/xwayland/xwm.h (limited to 'include/xwayland/xwm.h') diff --git a/include/xwayland/xwm.h b/include/xwayland/xwm.h new file mode 100644 index 00000000..0ed61d37 --- /dev/null +++ b/include/xwayland/xwm.h @@ -0,0 +1,132 @@ +#ifndef WLR_XWM_H +#define WLR_XWM_H + +#include +#include +#include + +#ifdef WLR_HAS_XCB_ICCCM + #include +#endif +#ifdef WLR_HAS_XCB_ERRORS + #include +#endif + +enum atom_name { + WL_SURFACE_ID, + WM_DELETE_WINDOW, + WM_PROTOCOLS, + WM_HINTS, + WM_NORMAL_HINTS, + WM_SIZE_HINTS, + MOTIF_WM_HINTS, + UTF8_STRING, + WM_S0, + NET_SUPPORTED, + NET_WM_S0, + NET_WM_PID, + NET_WM_NAME, + NET_WM_STATE, + NET_WM_WINDOW_TYPE, + WM_TAKE_FOCUS, + WINDOW, + _NET_ACTIVE_WINDOW, + _NET_WM_MOVERESIZE, + _NET_WM_NAME, + _NET_SUPPORTING_WM_CHECK, + _NET_WM_STATE_FULLSCREEN, + _NET_WM_STATE_MAXIMIZED_VERT, + _NET_WM_STATE_MAXIMIZED_HORZ, + WM_STATE, + CLIPBOARD, + PRIMARY, + WL_SELECTION, + TARGETS, + CLIPBOARD_MANAGER, + INCR, + TEXT, + TIMESTAMP, + NET_WM_WINDOW_TYPE_UTILITY, + NET_WM_WINDOW_TYPE_TOOLTIP, + NET_WM_WINDOW_TYPE_DND, + NET_WM_WINDOW_TYPE_DROPDOWN_MENU, + NET_WM_WINDOW_TYPE_POPUP_MENU, + NET_WM_WINDOW_TYPE_COMBO, + ATOM_LAST, +};
