This is done via a configuration file. ++ ++File location ++------------- ++ ++nxagent searches for the configuration file in the following order: ++- in the location given by the '-keystrokefile' command line parameter ++- in the location given by the NXAGENT_KEYSTROKEFILE environment variable ++- in ~/.nx/config/keystrokes.cfg ++- in /etc/nxagent/keystrokes.cfg ++ ++If none of those files is accessible, the default configuration is used which ++is the same as the old, traditional nxagent keybindings. ++ ++File format ++----------- ++ ++The configuration file is XML with the following format: ++ ++<!DOCTYPE NXKeystroke> ++<keystrokes> ++<keystroke action="fullscreen" AltMeta="1" Control="1" key="b" /> ++<keystroke action="minimize" AltMeta="1" Control="1" key="space" /> ++<keystroke action="minimize" key="Escape" Shift="1" /> ++<keystroke action="close_session" key="F7" /> ++<keystroke action="fullscreen" key="F7" Mod1="1" /> ++<keystroke action="fullscreen" key="F6" Mod1="1" /> ++<keystroke action="force_synchronization" key="f" /> ++<keystroke action="fullscreen" key="space" Mod1="0" Mod2="0" Control="0" Shift="0" AltMeta="0" /> ++</keystrokes> ++ ++Each 'action' defines an action to be executed when receiving that keystroke. A ++list of possible actions is given below. Some of those actions are only ++available with debug builds of nxagent. ++ ++Keys are given as a combination of 'key' and (optionally) a number of ++modifiers. The key attribute is evaluated into a X11 key via the usual ++XStringToKeysym function. A list of possible keys can be found in ++/usr/include/X11/keysymdef.h, the names are specified without the leading ++'XK_'. Evaluation is case-sensitive, so, 'space' and 'Escape' will work while ++'Space' and 'escape' won't. ++ ++Modifiers are given as boolean attributes, possible modifiers are Mod1, Mod2, ++Mod3, Mod4, Control, Shift, Lock. Sensible combinations strongly depend on your ++keyboard configuration, but usually you will need Mod1 and Control. Boolean in ++this context means '0', 'false' and an unspecified attribute are false, anything ++else is considered true. ++ ++Everything in this file is case-sensitive. Unknown lines are ignored. ++Keybindings are evaluated from top to bottom, so if a keybinding matches, other ++keybindings further down will be ignored. The contents of the file replaces the ++default keybindings, and only one file is read, no merging between different ++configuration files is done. This also means that an empty or invalid configuration ++file deactivates all keybindings. ++ ++List of possible 'action' attributes: ++------------------------------------- ++ ++close_session ++switch_all_screens ++minimize ++left ++up ++right ++down ++resize ++defer ++ignore ++fullscreen ++viewport_move_left ++viewport_move_up ++viewport_move_right ++viewport_move_down ++ ++Only in builds with certain debugging options enabled, ignored otherwise: ++force_synchronization ++debug_tree ++regions_on_screen ++test_input ++deactivate_input_devices_grab +--- a/nx-X11/programs/Xserver/hw/nxagent/Args.c ++++ b/nx-X11/programs/Xserver/hw/nxagent/Args.c +@@ -149,6 +149,8 @@ + + char nxagentVerbose = 0; + ++char *nxagentKeystrokeFile = NULL; ++ + int ddxProcessArgument(int argc, char *argv[], int i) + { + /* +@@ -1022,6 +1024,20 @@ + return 1; + } + ++ if (!strcmp(argv[i], "-keystrokefile")) ++ { ++ if (i + 1 < argc) ++ { ++ if (NULL != (nxagentKeystrokeFile = strdup(argv[i + 1]))) ++ { ++ return 2; ++ } else { ++ FatalError("malloc failed"); ++ } ++ } ++ return 0; ++ } ++ + return 0; + } + +--- a/nx-X11/programs/Xserver/hw/nxagent/Args.h ++++ b/nx-X11/programs/Xserver/hw/nxagent/Args.h +@@ -83,4 +83,6 @@ + + extern int nxagentRemoteMajor; + ++extern char *nxagentKeystrokeFile; ++ + #endif /* __Args_H__ */ |
