See feature request # 425722 * * Revision 1.6 2001/05/26 00:31:30 jongfoster * Fixing compiler warning about comparing signed/unsigned. * * Revision 1.5 2001/05/26 00:28:36 jongfoster * Automatic reloading of config file. * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32). * Most of the global variables have been moved to a new * struct configuration_spec, accessed through csp->config->globalname * Most of the globals remaining are used by the Win32 GUI. * * Revision 1.4 2001/05/22 18:56:28 oes * CRLF -> LF * * Revision 1.3 2001/05/20 15:07:54 jongfoster * File is now ignored if _WIN_CONSOLE is defined. * * Revision 1.2 2001/05/20 01:21:20 jongfoster * Version 2.9.4 checkin. * - Merged popupfile and cookiefile, and added control over PCRS * filtering, in new "permissionsfile". * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration * file error you now get a message box (in the Win32 GUI) rather * than the program exiting with no explanation. * - Made killpopup use the PCRS MIME-type checking and HTTP-header * skipping. * - Removed tabs from "config" * - Moved duplicated url parsing code in "loaders.c" to a new funcition. * - Bumped up version number. * * Revision 1.1.1.1 2001/05/15 13:59:07 oes * Initial import of version 2.9.3 source tree * * *********************************************************************/ #include "config.h" #include #include #include #include #include "project.h" #include "w32log.h" #include "w32taskbar.h" #include "w32rulesdlg.h" #include "win32.h" #include "w32res.h" #include "jcc.h" #include "miscutil.h" #include "errlog.h" const char w32res_h_rcs[] = W32RES_H_VERSION; #ifdef __MINGW32__ #include "cygwin.h" const char cygwin_h_rcs[] = CYGWIN_H_VERSION; #endif const char w32log_h_rcs[] = W32LOG_H_VERSION; #ifndef _WIN_CONSOLE /* entire file */ /* * Timers and the various durations */ #define TIMER_ANIM_ID 1 #define TIMER_ANIM_TIME 100 #define TIMER_ANIMSTOP_ID 2 #define TIMER_ANIMSTOP_TIME 1000 #define TIMER_CLIPBUFFER_ID 3 #define TIMER_CLIPBUFFER_TIME 1000 #define TIMER_CLIPBUFFER_FORCE_ID 4 #define TIMER_CLIPBUFFER_FORCE_TIME 5000 /* * Styles of text that can be output */ #define STYLE_NONE 0 #define STYLE_HIGHLIGHT 1 #define STYLE_LINK 2 #define STYLE_HEADER 3 /* * Number of frames of animation in tray activity sequence */ #define ANIM_FRAMES 8 #define DEFAULT_MAX_BUFFER_LINES 200 #define DEFAULT_LOG_FONT_NAME "MS Sans Serif" #define DEFAULT_LOG_FONT_SIZE 8 /* * These values affect the way the log window behaves, they should be read * from a file but for the moment, they are hardcoded here.
