From 1c8591d04ca0c88d816e1498f058db7fe948fb63 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jan=20Dj=C3=A4rv?= Date: Mon, 8 Jan 2007 17:56:31 +0000 Subject: [PATCH] New variable last_user_time. (handle_one_xevent): Set last_user_time from events that have Time. Set net_supported_window to 0 when reparented. (wm_supports): New function. (do_ewmh_fullscreen): Use wm_supports to check for _NET_WM_STATE. (x_term_init): Initialize net_supported_atoms, nr_net_supported_atoms and net_supported_window. --- src/xterm.c | 173 ++++++++++++++++++++++++++++++++++++++++------------ 1 file changed, 135 insertions(+), 38 deletions(-) diff --git a/src/xterm.c b/src/xterm.c index 0becc704a13..3b48caf0d36 100644 --- a/src/xterm.c +++ b/src/xterm.c @@ -277,6 +277,10 @@ static Lisp_Object last_mouse_scroll_bar; static Time last_mouse_movement_time; +/* Time for last user interaction as returned in X events. */ + +static Time last_user_time; + /* Incremented by XTread_socket whenever it really tries to read events. */ @@ -5869,6 +5873,7 @@ handle_one_xevent (dpyinfo, eventp, finish, hold_quit) break; case SelectionNotify: + last_user_time = event.xselection.time; #ifdef USE_X_TOOLKIT if (! x_window_to_frame (dpyinfo, event.xselection.requestor)) goto OTHER; @@ -5877,6 +5882,7 @@ handle_one_xevent (dpyinfo, eventp, finish, hold_quit) break; case SelectionClear: /* Someone has grabbed ownership. */ + last_user_time = event.xselectionclear.time; #ifdef USE_X_TOOLKIT if (! x_window_to_frame (dpyinfo, event.xselectionclear.window)) goto OTHER; @@ -5893,6 +5899,7 @@ handle_one_xevent (dpyinfo, eventp, finish, hold_quit) break; case SelectionRequest: /* Someone wants our selection. */ + last_user_time = event.xselectionrequest.time; #ifdef USE_X_TOOLKIT if (!x_window_to_frame (dpyinfo, event.xselectionrequest.owner)) goto OTHER; @@ -5913,6 +5920,7 @@ handle_one_xevent (dpyinfo, eventp, finish, hold_quit) break; case PropertyNotify: + last_user_time = event.xproperty.time; #if 0 /* This is plain wrong.
