Example: assume that we know: (A) lCtrl+rCtrl+rAlt modifiers with VK_A key produce a Latin "f" ("may be logical" in JCUKEN-flavored Russian keyboard flavors); (B) removing any of lCtrl, rCtrl, rAlt changes the produced char; (C) Win-modifier is not affecting the produced character (this is the common case: happens with all "standard" layouts). Suppose the user presses Win+lCtrl+rCtrl+rAlt modifiers with VK_A. What is the intent of the user? We need to guess the intent to decide which event to deliver to the application. This looks like a reasonable logic: since Win- modifier doesn't affect the output string, the user was pressing Win for SOME OTHER purpose. So the user wanted to generate Win-SOMETHING event. Now, what is something? If one takes the mantra that "character payload is more important than the combination of keypresses which resulted in this payload", then one should ignore lCtrl+rCtrl+rAlt, ignore VK_A, and assume that the user wanted to generate Win-f. Unfortunately, without non-destructive ToUnicode(), checking (B),(C) is out of question. So we use heuristics (hopefully, covering 99.9999% of cases). */ /* Another thing to watch for is a possibility to use AltGr-* and Ctrl-Alt-* with different semantic. Background: the layout defining the KLLF_ALTGR bit are treated specially by the kernel: when VK_RMENU (=rightAlt, =AltGr) is pressed (released), a press (release) of VK_LCONTROL is emulated (unless Ctrl is already down). As a result, any press/release of AltGr is seen by applications as a press/release of lCtrl AND rAlt. This is applicable, in particular, to ToUnicode[Ex](). (Keyrepeat is covered the same way!) NOTE: it IS possible to see bare rAlt even with KLLF_ALTGR; but this requires a good finger coordination: doing (physically) Down-lCtrl Down-rAlt Up-lCtrl Down-a (doing quick enough, so that key repeat of rAlt [which would generate new "fake" Down-lCtrl events] does not happens before 'a' is down) results in no "fake" events, so the application will see only rAlt down when 'a' is pressed. (However, fake Up-lCtrl WILL be generated when rAlt goes UP.) In fact, note also that KLLF_ALTGR does not prohibit construction of rCtrl-rAlt (just press them in this order!). Moreover: "traditional" layouts do not define distinct modifier-masks for VK_LMENU and VK_RMENU (same for VK_L/RCONTROL). Instead, they rely on the KLLF_ALTGR bit to make the behavior of VK_LMENU and VK_RMENU distinct. As a corollary, for such layouts, the produced character is the same for AltGr-* (=rAlt-*) and Ctrl-Alt-* (in any combination of handedness). For description of masks, see http://search.cpan.org/~ilyaz/UI-KeyboardLayout/lib/UI/KeyboardLayout.pm#Keyboard_input_on_Windows,_Part_I:_what_is_the_kernel_doing? By default, Emacs was using these coincidences via the following heuristics: it was treating: (*) keypresses with lCtrl-rAlt modifiers as if they are carrying ONLY the character payload (no matter what the actual keyboard was defining: if lCtrl-lAlt-b was delivering U+05df=beta, then Emacs saw [beta]; if lCtrl-lAlt-b was undefined in the layout, the keypress was completely ignored), and (*) keypresses with the other combinations of handedness of Ctrl-Alt modifiers (e.g., lCtrl-lAlt) as if they NEVER carry a character payload (so they were reported "raw": if lCtrl-lAlt-b was delivering beta, then Emacs saw event [C-A-b], and not [beta]). This worked good for "traditional" layouts: users could type both AltGr-x and Ctrl-Alt-x, and one was a character, another a bindable event. However, for layouts which deliver different characters for AltGr-x and lCtrl-lAlt-x, this scheme makes the latter character unaccessible in Emacs. While it is easy to access functionality of [C-M-x] in Emacs by other means (for example, by the `controlify' prefix, or using lCtrl-rCtrl-x, or rCtrl-rAlt-x [in this order]), missing characters cannot be reconstructed without a tedious manual work. */ /* These two cases are often going to be distinguishable, since at most one of these character is defined with KBDCTRL | KBDMENU modifier bitmap. (This heuristic breaks if both lCtrl-lAlt- AND lCtrl-rAlt- are translated to modifier bitmaps distinct from KBDCTRL | KBDMENU, or in the cases when lCtrl-lAlt-* and lCtrl-rAlt-* are generally different, but lCtrl-lAlt-x and lCtrl-rAlt-x happen to deliver the same character.) So we have 2 chunks of info: (A) is it lCtrl-rAlt-, or lCtrl-lAlt, or some other combination? (B) is the delivered character defined with KBDCTRL | KBDMENU bits? Basing on (A) and (B), we should decide whether to ignore the delivered character. (Before, Emacs was completely ignoring (B), and was treating the 3-state of (A) as a bit.) This means that we have 6 bits of customization. Additionally, a presence of two Ctrl down may be AltGr-rCtrl-. */ /* Strip all non-Shift modifiers if: - more than one UTF-16 code point delivered (can't call VkKeyScanW ()) - or the character is a result of combining with a prefix key. */ if (!after_dead && count == 1 && *b < 0x10000) { if (console_modifiers & (RIGHT_ALT_PRESSED | LEFT_ALT_PRESSED) && console_modifiers & (RIGHT_CTRL_PRESSED | LEFT_CTRL_PRESSED)) { type_CtrlAlt = "bB"; /* generic bindable Ctrl-Alt- modifiers */ if ((console_modifiers & (LEFT_CTRL_PRESSED | RIGHT_CTRL_PRESSED)) == (LEFT_CTRL_PRESSED | RIGHT_CTRL_PRESSED)) /* double-Ctrl: e.g. AltGr-rCtrl on some layouts (in this order!) */ type_CtrlAlt = "dD"; else if ((console_modifiers & (LEFT_CTRL_PRESSED | LEFT_ALT_PRESSED)) == (LEFT_CTRL_PRESSED | LEFT_ALT_PRESSED)) type_CtrlAlt = "lL"; /* Ctrl-Alt- modifiers on the left */ else if (!NILP (Vw32_recognize_altgr) && ((console_modifiers & (RIGHT_ALT_PRESSED | LEFT_CTRL_PRESSED))) == (RIGHT_ALT_PRESSED | LEFT_CTRL_PRESSED)) type_CtrlAlt = "gG"; /* modifiers as in AltGr */ } else if (wmsg.dwModifiers & (alt_modifier | meta_modifier) || ((console_modifiers & (LEFT_WIN_PRESSED | RIGHT_WIN_PRESSED | APPS_PRESSED | SCROLLLOCK_ON)))) { /* Pure Alt (or combination of Alt, Win, APPS, scrolllock. */ type_CtrlAlt = "aA"; } if (type_CtrlAlt) { /* Out of bound bitmap: */ SHORT r = VkKeyScanW (*b), bitmap = 0x1FF; FPRINTF_WM_CHARS((stderr, "VkKeyScanW %#06x %#04x\n", (int)r, wParam)); if ((r & 0xFF) == wParam) bitmap = r>>8; /* *b is reachable via simple interface */ if (*type_CtrlAlt == 'a') /* Simple Alt seen */ { if ((bitmap & ~1) == 0) /* 1: KBDSHIFT */ { /* In "traditional" layouts, Alt without Ctrl does not change the delivered character.

This is a wrapper around the ShellExecute system function, which invokes the application registered to handle OPERATION for DOCUMENT. OPERATION is either nil or a string that names a supported operation. What operations can be used depends on the particular DOCUMENT and its handler application, but typically it is one of the following common operations: \"open\" - open DOCUMENT, which could be a file, a directory, or an executable program (application). If it is an application, that application is launched in the current buffer's default directory. Otherwise, the application associated with DOCUMENT is launched in the buffer's default directory. \"opennew\" - like \"open\", but instruct the application to open DOCUMENT in a new window. \"openas\" - open the \"Open With\" dialog for DOCUMENT. \"print\" - print DOCUMENT, which must be a file. \"printto\" - print DOCUMENT, which must be a file, to a specified printer. The printer should be provided in PARAMETERS, see below. \"explore\" - start the Windows Explorer on DOCUMENT. \"edit\" - launch an editor and open DOCUMENT for editing; which editor is launched depends on the association for the specified DOCUMENT. \"find\" - initiate search starting from DOCUMENT, which must specify a directory. \"delete\" - move DOCUMENT, a file or a directory, to Recycle Bin. \"copy\" - copy DOCUMENT, which must be a file or a directory, into the clipboard. \"cut\" - move DOCUMENT, a file or a directory, into the clipboard. \"paste\" - paste the file whose name is in the clipboard into DOCUMENT, which must be a directory. \"pastelink\" - create a shortcut in DOCUMENT (which must be a directory) the file or directory whose name is in the clipboard. \"runas\" - run DOCUMENT, which must be an excutable file, with elevated privileges (a.k.a. \"as Administrator\"). \"properties\" - open the property sheet dialog for DOCUMENT. nil - invoke the default OPERATION, or \"open\" if default is not defined or unavailable. DOCUMENT is typically the name of a document file or a URL, but can also be an executable program to run, or a directory to open in the Windows Explorer. If it is a file or a directory, it must be a local one; this function does not support remote file names. If DOCUMENT is an executable program, the optional third arg PARAMETERS can be a string containing command line parameters, separated by blanks, that will be passed to the program. Some values of OPERATION also require parameters (e.g., \"printto\" requires the printer address). Otherwise, PARAMETERS should be nil or unspecified. Note that double quote characters in PARAMETERS must each be enclosed in 2 additional quotes, as in \"\"\". Optional fourth argument SHOW-FLAG can be used to control how the application will be displayed when it is invoked. If SHOW-FLAG is nil or unspecified, the application is displayed as if SHOW-FLAG of 10 was specified, otherwise it is an integer between 0 and 11 representing a ShowWindow flag: 0 - start hidden 1 - start as normal-size window 3 - start in a maximized window 6 - start in a minimized window 10 - start as the application itself specifies; this is the default. */) (Lisp_Object operation, Lisp_Object document, Lisp_Object parameters, Lisp_Object show_flag) { char *errstr; Lisp_Object current_dir = BVAR (current_buffer, directory);; wchar_t *doc_w = NULL, *params_w = NULL, *ops_w = NULL; #ifdef CYGWIN intptr_t result; #else int use_unicode = w32_unicode_filenames; char *doc_a = NULL, *params_a = NULL, *ops_a = NULL; Lisp_Object absdoc, handler; BOOL success; #endif CHECK_STRING (document); #ifdef CYGWIN current_dir = Fcygwin_convert_file_name_to_windows (current_dir, Qt); document = Fcygwin_convert_file_name_to_windows (document, Qt); /* Encode filename, current directory and parameters. */ current_dir = GUI_ENCODE_FILE (current_dir); document = GUI_ENCODE_FILE (document); doc_w = GUI_SDATA (document); if (STRINGP (parameters)) { parameters = GUI_ENCODE_SYSTEM (parameters); params_w = GUI_SDATA (parameters); } if (STRINGP (operation)) { operation = GUI_ENCODE_SYSTEM (operation); ops_w = GUI_SDATA (operation); } result = (intptr_t) ShellExecuteW (NULL, ops_w, doc_w, params_w, GUI_SDATA (current_dir), (INTEGERP (show_flag) ?

Value is the integer unique ID of the notification that can be used to remove the notification using `w32-notification-close', which see. If the function fails, the return value is nil. Tray notifications, a.k.a. \"taskbar messages\", are messages that inform the user about events unrelated to the current user activity, such as a significant system event, by briefly displaying informative text in a balloon from an icon in the notification area of the taskbar. Parameters in PARAMS are specified as keyword/value pairs. All the parameters are optional, but if no parameters are specified, the function will do nothing and return nil. The following parameters are supported: :icon ICON -- Display ICON in the system tray. If ICON is a string, it should specify a file name from which to load the icon; the specified file should be a .ico Windows icon file. If ICON is not a string, or if this parameter is not specified, the standard Emacs icon will be used. :tip TIP -- Use TIP as the tooltip for the notification. If TIP is a string, this is the text of a tooltip that will be shown when the mouse pointer hovers over the tray icon added by the notification. If TIP is not a string, or if this parameter is not specified, the default tooltip text is \"Emacs notification\". The tooltip text can be up to 127 characters long (63 on Windows versions before W2K). Longer strings will be truncated. :level LEVEL -- Notification severity level, one of `info', `warning', or `error'. If given, the value determines the icon displayed to the left of the notification title, but only if the `:title' parameter (see below) is also specified and is a string. :title TITLE -- The title of the notification. If TITLE is a string, it is displayed in a larger font immediately above the body text. The title text can be up to 63 characters long; longer text will be truncated. :body BODY -- The body of the notification. If BODY is a string, it specifies the text of the notification message. Use embedded newlines to control how the text is broken into lines. The body text can be up to 255 characters long, and will be truncated if it's longer. Note that versions of Windows before W2K support only `:icon' and `:tip'. You can pass the other parameters, but they will be ignored on those old systems.
