Various |gui-w32-various| Other relevant documentation: |gui.txt| For generic items of the GUI. |os_win32.txt| For Win32 specific items. ============================================================================== 1. Starting the GUI *gui-w32-start* The Win32 GUI version of MNV will always start the GUI, no matter how you start it or what it's called. The GUI will always run in the Windows subsystem. Mostly shells automatically return with a command prompt after starting gmnv. If not, you should use the "start" command: > start gmnv [options] file .. < *E988* The console version with the |-g| option may also start the GUI by executing gmnv.exe: > mnv -g [options] file .. To make this work, gmnv.exe must exist in the same directory as the mnv.exe, and this feature must be enabled at compile time. One may also use `:gui` from the console version. However, this is an experimental feature and this feature must be enabled at compile time. It uses a session file to recreate the current state of the console MNV in the GUI MNV. Note: All fonts (bold, italic) must be of the same size!!! If you don't do this, text will disappear or mess up the display. MNV does not check the font sizes. It's the size in screen pixels that must be the same. Note that some fonts that have the same point size don't have the same pixel size! Additionally, the positioning of the fonts must be the same (ascent and descent). The Win32 GUI has an extra menu item: "Edit/Select Font". It brings up the standard Windows font selector. Setting the menu height doesn't work for the Win32 GUI. *gui-win32-maximized* If you want MNV to start with a maximized window, add this command to your mnvrc or gmnvrc file: > au GUIEnter * simalt ~x < Using MNV as a plugin *gui-w32-windowid* When gmnv starts up normally, it creates its own top level window. If you pass MNV the command-line option |--windowid| with a decimal or hexadecimal value, MNV will create a window that is a child of the window with the given ID. This enables MNV to act as a plugin in another application. This really is a programmer's interface, and is of no use without a supporting application to spawn MNV correctly. ============================================================================== 2. MNV as default editor *mnv-default-editor* To set MNV as the default editor for a file type: 1. Start a Windows Explorer 2. Choose View/Options -> File Types 3. Select the path to gmnv for every file type that you want to use it for. (you can also use three spaces in the file type field, for files without an extension). In the "open" action, use: > gmnv "%1" < The quotes are required for using file names with embedded spaces. You can also use this: > gmnv "%L" < This should avoid short (8.3 character) file names in some situations. But I'm not sure if this works everywhere. When you open a file in MNV by double clicking it, MNV changes to that file's directory. If you want MNV to start full-screen, use this for the Open action: > gmnv -c "simalt ~x" "%1" Another method, which also works when you put MNV in another directory (e.g., when you have got a new version): 1. select a file you want to use MNV with 2. 3. select "Open With..." menu entry 4. click "Other..." 5. browse to the (new) location of MNV and click "Open" 6. make "Always Use this program..." checked 7. *send-to-menu* *sendto* You can also install MNV in the "Send To" menu: 1. Start a Windows Explorer 2. Navigate to your sendto directory: C:\Users\%user%\AppData\Roaming\Microsoft\Windows\SendTo . 3. Right-click in the file pane and select New->Shortcut 4. Follow the shortcut wizard, using the full path to MNV/GMNV. When you 'send a file to MNV', MNV changes to that file's directory. Note, however, that any long directory names will appear in their short (MS-DOS) form on some Windows versions. This is a limitation of the Windows "Send To" mechanism. *notepad* You could replace notepad.exe with gmnv.exe, but that has a few side effects. Some programs rely on notepad arguments, which are not recognized by MNV. For example "notepad -p" is used by some applications to print a file. It's better to leave notepad where it is and use another way to start MNV. *win32-popup-menu* A more drastic approach is to install an "Edit with MNV" entry in the popup menu for the right mouse button. With this you can edit any file with MNV. This can co-exist with the file associations mentioned above. The difference is that the file associations will make starting MNV the default action. With the "Edit with MNV" menu entry you can keep the existing file association for double clicking on the file, and edit the file with MNV when you want. For example, you can associate "*.mak" with your make program. You can execute the makefile by double clicking it and use the "Edit with MNV" entry to edit the makefile. You can select any files and right-click to see a menu option called "Edit with gmnv". Choosing this menu option will invoke gmnv with the file you have selected. If you select multiple files, you will find two gmnv-related menu options: "Edit with multiple gmnvs" -- one gmnv for each file in the selection "Edit with single gmnv" -- one gmnv for all the files in the selection And if there already is a gmnv running: "Edit with existing gmnv" -- edit the file with the running gmnv The "edit with existing MNV" entries can be disabled by adding an entry in the registry under HKLM\Software\MNV\Gmnv, named DisableEditWithExisting, and with any value. *install-registry* You can add the "Edit with MNV" menu entry in an easy way by using the "install.exe" program. It will add several registry entries for you. You can also do this by hand. This is complicated! Use the install.exe if you can. 1. Start the registry editor with "regedit". 2. Add these keys: key value name value ~ HKEY_CLASSES_ROOT\CLSID\{51EEE242-AD87-11d3-9C1E-0090278BBD99} {default} MNV Shell Extension HKEY_CLASSES_ROOT\CLSID\{51EEE242-AD87-11d3-9C1E-0090278BBD99}\InProcServer32 {default} {path}\gmnvext.dll ThreadingModel Apartment HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\gmnv {default} {51EEE242-AD87-11d3-9C1E-0090278BBD99} HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved {51EEE242-AD87-11d3-9C1E-0090278BBD99} MNV Shell Extension HKEY_LOCAL_MACHINE\Software\MNV\Gmnv path {path}\gmnv.exe HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\mnv 8.2 DisplayName MNV 8.2: Edit with MNV popup menu entry UninstallString {path}\uninstall.exe Replace {path} with the path that leads to the executable. Don't type {default}, this is the value for the key itself. To remove "Edit with MNV" from the popup menu, just remove the registry entries mentioned above. The "uninstall.exe" program can do this for you. You can also use the entry in the Windows standard "Add/Remove Programs" list. If you notice that this entry overrules other file type associations, set those associations again by hand (using Windows Explorer, see above). This only seems to happen on some Windows NT versions (Windows bug?). Procedure: 1. Find the name of the file type. This can be done by starting the registry editor, and searching for the extension in \\HKEY_CLASSES_ROOT 2. In a Windows Explorer, use View/Options/File Types. Search for the file type in the list and click "Edit". In the actions list, you can select on to be used as the default (normally the "open" action) and click on the "Set Default" button. MNV in the "Open With..." context menu *win32-open-with-menu* If you use the MNV install program you have the choice to add MNV to the "Open With..." menu. This means you can use MNV to edit many files. Not every file (for unclear reasons...), thus the "Edit with MNV" menu entry is still useful. One reason to add this is to be able to edit HTML files directly from Internet Explorer. To enable this use the "Tools" menu, "Internet Options..." entry. In the dialog select the "Programs" tab and select MNV in the "HTML editor" choice. If it's not there then installing didn't work properly. Doing this manually can be done with this script: ---------------------------------------------------------- REGEDIT4 [HKEY_CLASSES_ROOT\Applications\gmnv.exe] [HKEY_CLASSES_ROOT\Applications\gmnv.exe\shell] [HKEY_CLASSES_ROOT\Applications\gmnv.exe\shell\edit] [HKEY_CLASSES_ROOT\Applications\gmnv.exe\shell\edit\command] @="c:\\mnv\\mnv82\\gmnv.exe \"%1\"" [HKEY_CLASSES_ROOT\.htm\OpenWithList\gmnv.exe] [HKEY_CLASSES_ROOT\*\OpenWithList\gmnv.exe] ---------------------------------------------------------- Change the "c:\\mnv\\mnv82" bit to where gmnv.exe is actually located. To uninstall this run the MNV uninstall program or manually delete the registry entries with "regedit". ============================================================================== 3. Using the clipboard *gui-clipboard* Windows has a clipboard, where you can copy text to, and paste text from. MNV supports this in several ways. For other systems see |gui-selections|. The "* register reflects the contents of the clipboard. |quotestar| When the "unnamed" string is included in the 'clipboard' option, the unnamed register is the same. Thus you can yank to and paste from the clipboard without prepending "* to commands. If this doesn't work use the "unnamedplus" string in the 'clipboard' option. The 'a' flag in 'guioptions' is not included by default. This means that text is only put on the clipboard when an operation is performed on it. Just Visually selecting text doesn't put it on the clipboard. When the 'a' flag is included, the text is copied to the clipboard even when it is not operated upon. *mswin.mnv* To use the standard MS-Windows way of CTRL-X, CTRL-C and CTRL-V, use the $MNVRUNTIME/mswin.mnv script. You could add this line to your _mnvrc file: > source $MNVRUNTIME/mswin.mnv Since CTRL-C is used to copy the text to the clipboard, it can't be used to cancel an operation. Use CTRL-Break for that. CTRL-Z is used for undo. This means you can't suspend MNV with this key, use |:suspend| instead (if it's supported at all). *CTRL-V-alternative* *CTRL-Q* Since CTRL-V is used to paste, you can't use it to start a blockwise Visual selection. You can use CTRL-Q instead. You can also use CTRL-Q in Insert mode and Command-line mode to get the old meaning of CTRL-V. But CTRL-Q doesn't work for terminals when it's used for control flow. NOTE: The clipboard support still has a number of bugs. See |todo|. ============================================================================== 4. Shell Commands *gui-shell-win32* MNV uses another window for external commands, to make it possible to run any command. The external command gets its own environment for running, just like it was started from a DOS prompt. *win32-mnvrun* Executing an external command is done indirectly by the "mnvrun" command. The "mnvrun.exe" must be in the path for this to work. Or it must be in the same directory as the MNV executable. If "mnvrun" cannot be found, the command is executed directly, but then the DOS window closes immediately after the external command has finished. WARNING: If you close this window with the "X" button, and confirm the question if you really want to kill the application, MNV may be killed too! (This does not apply to commands run asynchronously with ":!start".) The window in which the commands are executed will be the default you have set up for "Console" in Control Panel. *win32-!start* Normally, MNV waits for a command to complete before continuing (this makes sense for most shell commands which produce output for MNV to use). If you want MNV to start a program and return immediately, you can use the following syntax: > :!start [/min] {command} The optional "/min" causes the window to be minimized. ============================================================================== 5. Special colors *win32-colors* On Win32, the normal DOS colors can be used. See |dos-colors|. Additionally the system configured colors can also be used. These are known by the names Sys_XXX, where XXX is the appropriate system color name, from the following list (see the Win32 documentation for full descriptions). Case is ignored. Sys_3DDKShadow Sys_3DFace Sys_BTNFace Sys_3DHilight Sys_3DHighlight Sys_BTNHilight Sys_BTNHighlight Sys_3DLight Sys_3DShadow Sys_BTNShadow Sys_ActiveBorder Sys_ActiveCaption Sys_AppWorkspace Sys_Background Sys_Desktop Sys_BTNText Sys_CaptionText Sys_GrayText Sys_Highlight Sys_HighlightText Sys_InactiveBorder Sys_InactiveCaption Sys_InactiveCaptionText Sys_InfoBK Sys_InfoText Sys_Menu Sys_MenuText Sys_ScrollBar Sys_Window Sys_WindowFrame Sys_WindowText Probably the most useful values are Sys_Window Normal window background Sys_WindowText Normal window text Sys_Highlight Highlighted background Sys_HighlightText Highlighted text These extra colors are also available: Gray, Grey, LightYellow, SeaGreen, Orange, Purple, SlateBlue, Violet, *rgb.txt* Additionally, colors defined by a default color list can be used. For more info see |:colorscheme|. These colors used to be defined in $MNVRUNTIME/rgb.txt, now they are in |v:colornames| which is initialized from $MNVRUNTIME/colors/lists/default.mnv. ============================================================================== *gui-w32-dialogs* *dialog* 6. Windows dialogs & browsers The Win32 GUI can use familiar Windows components for some operations, as well as the traditional interface shared with the console version. 6.1 Dialogs The dialogs displayed by the "confirm" family (i.e. the 'confirm' option, |:confirm| command and |confirm()| function) are GUI-based rather than the console-based ones used by other versions. The 'c' flag in 'guioptions' changes this. 6.2 File Browsers When prepending ":browse" before file editing commands, a file requester is used to allow you to select an existing file. See |:browse|. 6.3 Tearoff Menus The Win32 GUI emulates Motif's tear-off menus. At the top of each menu you will see a small graphic "rip here" sign. Selecting it will cause a floating window to be created with the same menu entries on it. The floating menu can then be accessed just as if it was the original (including sub-menus), but without having to go to the menu bar each time. This is most useful if you find yourself using a command buried in a sub-menu over and over again. The tearoff menus can be positioned where you like, and always stay just above the Main MNV window. You can get rid of them by closing them as usual; they also of course close when you exit MNV. *:tearoff* *:te* :te[aroff] {name} Tear-off the menu {name}. The menu named must have at least one subentry, but need not appear on the menu-bar (see |win32-hidden-menus|). Example: > :tearoff File will make the "File" menu (if there is one) appear as a tearoff menu. > :amenu ]Toolbar.Make :make :tearoff ]Toolbar This creates a floating menu that doesn't exist on the main menu-bar. Note that a menu that starts with ']' will not be displayed. ============================================================================== 7. Command line arguments *gui-w32-cmdargs* Command line arguments behave the same way as with the console application, see |win32-cmdargs|. ============================================================================== 8. Various *gui-w32-various* *gui-w32-printing* The "File/Print" menu prints the text with syntax highlighting, see |:hardcopy|. If you just want to print the raw text and have a default printer installed this should also work: > :w >>prn MNV supports a number of standard MS-Windows features. Some of these are detailed elsewhere: see 'mouse', |win32-hidden-menus|. *drag-n-drop-win32* You can drag and drop one or more files into the MNV window, where they will be opened as normal. See |drag-n-drop|. *:simalt* *:sim* :sim[alt] {key} simulate pressing {key} while holding Alt pressed. {only for Win32 versions} Note: ":si" means ":s" with the "i" flag. Normally, MNV takes control of all Alt- combinations, to increase the number of possible mappings. This clashes with the standard use of Alt as the key for accessing menus. The quick way of getting standard behavior is to set the 'winaltkeys' option to "yes". This however prevents you from mapping Alt keys at all. Another way is to set 'winaltkeys' to "menu". Menu shortcut keys are then handled by windows, other ALT keys can be mapped. This doesn't allow a dependency on the current state though. To get round this, the :simalt command allows MNV (when 'winaltkeys' is not "yes") to fake a Windows-style Alt keypress. You can use this to map Alt key combinations (or anything else for that matter) to produce standard Windows actions. Here are some examples: > :map :simalt f This makes Alt-F pop down the 'File' menu (with the stock Menu.mnv) by simulating the keystrokes Alt, F. > :map :simalt ~ This maps Alt-Space to pop down the system menu for the MNV window. Note that ~ is used by simalt to represent the character. > :map :simalt ~n Maps Control-N to produce the keys Alt-Space followed by N. This minimizes the MNV window via the system menu. Note that the key changes depending on the language you are using. *intellimouse-wheel-problems* When using the Intellimouse mouse wheel causes MNV to stop accepting input, go to: ControlPanel - Mouse - Wheel - UniversalScrolling - Exceptions And add gmnv to the list of applications. This problem only appears to happen with the Intellimouse driver 2.2 and when "Universal Scrolling" is turned on. XPM support *w32-xpm-support* GMNV can be built on MS-Windows with support for XPM files. |+xpm_w32| See the Make_mvc.mak file for instructions, search for XPM. To try out if XPM support works do this: > :help :let runtime = escape($MNVRUNTIME, ' \') :exe 'sign define mnvxpm icon=' .. runtime .. '\\mnv16x16.xpm' :exe 'sign place 1 line=1 name=mnvxpm file=' .. expand('%:p') < You may need to get the mnv16x16.xpm file from github: https://github.com/Project-Tick/Project-Tick/blob/master/runtime/mnv16x16.xpm Keycode translation strategy *w32-experimental-keycode-trans-strategy* In Patch v8.2.4807 W32 GMNV was changed over to experimental keycode translation method with the aim to be able to use more keyboard shortcuts and especially supporting non-standard keyboard layouts. In order to implement this support Win API TranslateMessage() call was dropped, and instead the recognition of keycode was changed over to ToUnicode() Win API call. This approach uncovered numerous corner cases, which are apparently covered by TranslateMessage() implementation, each of it is necessary to be dealt with on an individual basis. Therefore the decision was taken to declare this functionality experimental for the time being and to recover "classic" keycode translation method as default again. Discussion about use of "experimental" keycode translation method will probably last some time yet. In the meantime, if you are impacted by this change over back to "classic" keycode translation method in W32 GMNV, you can enable "experimental" translation method again in your mnvrc using following snippet: > :call test_mswin_event('set_keycode_trans_strategy', {'strategy': 'experimental'}) < Similarly, in case you need to turn back "classic" keycode translation method (for example for testing purposes), please use: > :call test_mswin_event('set_keycode_trans_strategy', {'strategy': 'classic'}) < Alternatively (this method is especially useful for the TINY GMNV build, where test_mswin_event() cannot be called), an environment variable MNV_KEYCODE_TRANS_STRATEGY can be set to the desired value ("experimental" or "classic"), to override the default, e.g., type in dos prompt: > set MNV_KEYCODE_TRANS_STRATEGY=experimental gmnv.exe < Title Bar *gui-w32-title-bar* Starting with Windows 11, you can customize the gMNV title bar (also known as the caption bar) by enabling the |'go-C'| option. Once enabled, the appearance is controlled by two highlighting groups: 1. |hl-TitleBar| -- Sets the color of the title bar for the active window. 2. |hl-TitleBarNC| -- Sets the color of the title bar for inactive windows. To use the system's default title bar colors, set highlighting groups to `NONE`: > hi TitleBar guibg=NONE guifg=NONE hi TitleBarNC guibg=NONE guifg=NONE < Full Screen *gui-w32-fullscreen* To enable fullscreen mode in the Windows GUI version of MNV, add the 's' flag to the 'guioptions' setting. For convenience, you can define a command or mapping to toggle fullscreen mode: > command ToggleFullscreen { if &guioptions =~# 's' set guioptions-=s else set guioptions+=s endif } map &go =~# 's' ? ":se go-=s" : ":se go+=s" The fullscreen mode will occupy the entire screen area while hiding window decorations such as the title bar and borders. mnv:tw=78:sw=4:ts=8:noet:ft=help:norl:
