      Would it be possible to add feature:

      Probably not reasonable as a feature addition.
      Probably very doable as a script.

        Here’s a barebones PythonScript that shows how this could work:

        notepad.menuCommand(MENUCOMMAND.VIEW_CLONE_TO_ANOTHER_VIEW)
        editor2.setFirstVisibleLine(editor1.getFirstVisibleLine() + editor1.linesOnScreen())
        notepad.menuCommand(MENUCOMMAND.VIEW_SYNSCROLLV)
        

        Because Notepad++'s View menu’s Synchronize Vertical Scrolling choice is a toggle, however, the above only works if it is currently off. This is a problem with a few Notepad++ menu commands and scripts.

        I wonder if @Ekopalypse has some ideas about some script code that can read the status of a checkable menu item? Ideally it would depend only upon command-id (e.g. 44035 in this case) and not the text of the menu item (to avoid problems with using N++ in a different localization).

          I ASSUME i can be done using GetMenuItemInfoW and MENUITEMINFOW. Will follow up later, probably tomorrow.

              Nice – works fine!
              Thank you.

                I turned your script into the following recursive function that finds a specified id:

                def menu_search_for_specified_id(menu_handle, id_to_find):  # returns ( direct-menu-handle, position-on-menu )
                    menu_item_count = user32.GetMenuItemCount(menu_handle)
                    for menu_pos in range(menu_item_count):
                        sub_menu_handle = user32.GetSubMenu(menu_handle, menu_pos)
                        if sub_menu_handle != 0:
                            (h, p) = menu_search_for_specified_id(sub_menu_handle, id_to_find)
                            if h != 0: return (h, p)
                        else:
                            mii = MENUITEMINFO()
                            mii.cbSize = ctypes.sizeof(mii)
                            mii.fMask = MIIM_ID
                            mii.dwTypeData = None
                            lpmii = ctypes.byref(mii)
                            user32.GetMenuItemInfoW(menu_handle, menu_pos, True, lpmii)
                            if mii.wID == id_to_find: return (menu_handle, menu_pos)
                    return (0, 0)  # nothing found
                

                I’ll keep going with a final solution for the OP’s request, that uses this…interested parties please check back later. :-)

                  • You can Clone the text document to the other view. (Dual View).
                  • Scroll down to about page length.
                  • And then use Synchronized Vertical Scrolling feature to have Two-Page View in Notepad++.

                  This is not a fully automated feature but one that you can do it very easily.

                  This video shows how you can use Synchronized Vertical/horizontal scrolling feature in Notepad++. Hope it helps.

                      I found time sooner than I thought to integrate the menu-search function into the main code for this thread’s topic.

                      Here’s a replacement script; obviously, quite a bit more complicated.
                      But, due to the virtues of encapsulation, the run() function looks very much like the original, simpler script (the first script provided in this thread).

                      I call the script CloneActiveDocAndCreateDualPageView.py and here’s its code:

                      # -*- coding: utf-8 -*-
                      
                      from Npp import editor, notepad, MENUCOMMAND

                      MIIM_STATE = 1
                      MIIM_ID = 2
                      MFS_DISABLED = 0x3
                      MFS_CHECKED = 0x8
                      
                      class MENUITEMINFO(ctypes.Structure):
                          _fields_ = [

                        One thing I noticed… In the code you provided, you called:

                        notepad.getMenuHandle(1)

                        and it works to get the main-menu handle (I suppose! because the rest of the logic works!).

                        But the documentation for this says 0 should be the main menu:

                        507731ce-419d-4953-80dd-f062f40fa196-image.png

                        Is my PythonScript documentation simply out-of-date in this regard?
                        Or…?

                          Not sure if this is an issue with PS code or documentation?
                          But yes, 1 seems to return the main and 0 the plugin handle.

                            When I implemented in perl, I used 1 for main and 0 for plugin. The NPPM_GETMENUHANDLE docs agree that 1 is main.

                            The PS docs are wrong.
