    Hello Claudia,

    That’s brilliant. Thanks again for your time.

    If you want the command executed on right-up, move

    RIGHT_CLICK_MODE = True
    # execute script
    notepad.menuCommand(_tbbutton.idCommand)
    

    to elif msg == 0x0205:.

    Also, you can use windll.user32.mouse_event(0x0002, 0, 0, 0, 0) without a timer.

    	def sciWndProc(self, hWnd, msg, wParam, lParam):
    		global REAL_RIGHT_UP
    		global RIGHT_CLICK_MODE
    		if msg == 0x0204:		# WM_RBUTTONDOWN.
    			REAL_RIGHT_UP = False
    			windll.user32.mouse_event(0x0002, 0, 0, 0, 0)	# Left down. WM_RBUTTONUP is sent although the right button is still down.
    		elif msg == 0x0205:	# WM_RBUTTONUP.
    			if REAL_RIGHT_UP:		# Another WM_RBUTTONUP is sent when the right button is released. Process it now.
    				RIGHT_CLICK_MODE = True
    				windll.user32.mouse_event(0x0004, 0, 0, 0, 0)	# Left up.
    
    			REAL_RIGHT_UP = True
    		elif REAL_RIGHT_UP and msg == 0x0201:		# WM_LBUTTONDOWN.
    			RIGHT_CLICK_MODE = False
    
    		return windll.user32.CallWindowProcA (self.oldWndProc, hWnd, msg, wParam, lParam)
    

    Have a nice weekend.

      Hello Claudia,

      I had a closer look at your code and it’s really nice. Thanks again.

      Getting the button ID is certainly the “proper” approach.
      For the record, here is a shorter mouse_event implementation.

      	def sciWndProc(self, hWnd, msg, wParam, lParam):
      		global RIGHT_CLICK_MODE
      		if msg == 0x0204:		# WM_RBUTTONDOWN.
      			windll.user32.mouse_event(0x0002, 0, 0, 0, 0)	# Left down. WM_RBUTTONUP is sent although the right button is still down.
      		elif msg == 0x0205:	# WM_RBUTTONUP.
      			if RIGHT_CLICK_MODE:		# Another WM_RBUTTONUP is sent when the right button is released. Send "Left up" now.
      				windll.user32.mouse_event(0x0004, 0, 0, 0, 0)	# Left up.
      			else:	# The right button is still down.
      				RIGHT_CLICK_MODE = True
      		elif RIGHT_CLICK_MODE and msg == 0x0201:		# WM_LBUTTONDOWN.
      			RIGHT_CLICK_MODE = False
      
      		return windll.user32.CallWindowProcA (self.oldWndProc, hWnd, msg, wParam, lParam)
      

      This is PythonScript console when using NPP in a RTL layout.
      default

      Reading the LTR output in a RTL layout is obviously inconvenient.

      @dail has kindly added an option to force LuaScript console to LTR.
      https://github.com/dail8859/LuaScript/issues/6#issuecomment-270676744
      https://github.com/dail8859/LuaScript/commit/8fed28f8ffe494c5e68a02010fddcdac4b4d3f74

      Do you think it would be possible to force PythonScript console to LTR using some code in startup.py ?
      Or would it require some modifications in PythonScript source files?

      If and when you have some time to think about it, I’d be grateful.

      Best regards.

        Hello Yaron,

        if dails commit solves your issue with lua then I don’t see why we could get this to work with python script.
        The hard work to find out what needs to be done has been already done by @dail, thank you ;-).

        So we need to get the window hwnd from python script console (and what about the inputbox?)
        and change the style parameter for that window. Doesn’t sound undoable.

        Obviously I tend to solve using a python script but if you prefer I will see what needs to be changed in plugin source in order
        to make it happen but compiling and testing needs to be done on your site.

        Cheers
        Claudia

          Yaron,
          Am I right to assume that you do not only need RTL layout but also RTL reading, correct?
          Or do you really want to have LTR layout in python script while using RTL layout in npp?

          Cheers
          Claudia

              Hello Claudia,

              Thank you for your patience and kindness. Highly appreciated.
              And allow me to thank @dail again for LuaScript in general and for the console issue in particular.

              I assumed it was possible to change PythonScript console to LTR but I preferred to get the right direction by consulting with the expert first. :)
              And, as usual, you already have the solution.

              (and what about the inputbox?)

              The InputBox in PythonScript is LTR even when NPP layout is RTL (so it doesn’t have to be modified).

              Obviously I tend to solve using a python script…

              That would be great.

              Am I right to assume that you do not only need RTL layout but also RTL reading, correct?

              You can change NPP text direction whether the layout is LTR or RTL (View -> Text Direction LTR/RTL).

              Or do you really want to have LTR layout in python script while using RTL layout in npp?

              Indeed.
              The console’s frame and input are always LTR. The problem is the output.

              Looking at your screenshot, I understand the the issue should be further clarified. :)

              This is NPP in RTL layout with LuaSceipt console in LTR (perfect).
              default

              And this is NPP in RTL layout with PythonSceipt console in LTR (frame and input) and RTL (output - confusing).
              default

              I’d like to see the output as you see it in LTR layout.

              This may further complicate the issue but OTOH it might help.
              The status bar in both screenshots is LTR.
              As I wrote to dail, I added the following line in StatusBar.cpp:

              // Change to LTR. "WS_CHILD & (~WS_EX_LAYOUTRTL)" above won't work because WS_EX_LAYOUTRTL is added AFTER the bar has been created and inherited the RTL layout.
              ::SetWindowLongPtr(_hSelf, GWL_EXSTYLE, ::GetWindowLongPtr(_hSelf, GWL_EXSTYLE) & (~WS_EX_LAYOUTRTL)); 
              

              after

              if (!_hSelf)
              		throw std::runtime_error("StatusBar::init : CreateWindowEx() function return null");
              

              So getting the console’s handle (or only the output’s?) and changing the WS_EX_LAYOUTRTL style should work. :)

              Can SetWindowLongPtr() be used via 'ctypes`?

              Thanks again and good night.

                Hello Yaron,

                ok and yes SetWindowLongPtr() can be used.
                I didn’t came across a windows api function which can’t be used with ctypes yet.
                This is a toggle function which sets WS_EX_LAYOUTRTL if not set and unset
                if was already set.

                WNDENUMPROC = WINFUNCTYPE(wintypes.BOOL,
                                          wintypes.HWND,
                                          wintypes.LPARAM)
                
                
                python_script_hwnd = None
                python_script_sci_handle = None
                
                GWL_EXSTYLE = -20
                WS_EX_LAYOUTRTL = 0x00400000
                
                def EnumCallback(hwnd, lparam):
                    global python_script_hwnd
                    global python_script_sci_handle
                    
                    curr_class = (wintypes.WCHAR * 256)()
                    curr_name = (wintypes.WCHAR * 256)()
                   
                    windll.user32.GetClassNameW(hwnd, curr_class, 256)
                    windll.user32.GetWindowTextW(hwnd, curr_name, 256)
                
                    if curr_name.value.lower() == 'python script':
                        python_script_hwnd = hwnd
                    else:
                        if python_script_hwnd is not None:
                            if curr_class.value.lower() == 'scintilla':
                                if windll.user32.GetParent(hwnd) == python_script_hwnd:
                                    python_script_sci_handle = hwnd
                                    return False
                       
                    return True
                
                parent = windll.user32.FindWindowA('Notepad++', None)
                windll.user32.EnumChildWindows(parent, WNDENUMPROC(EnumCallback), 0)
                windll.user32.EnumChildWindows(python_script_hwnd, WNDENUMPROC(EnumCallback), 0)
                
                exStyle = windll.user32.GetWindowLongA(python_script_sci_handle, GWL_EXSTYLE)
                
                if (exStyle & WS_EX_LAYOUTRTL):
                    exStyle = exStyle & WS_EX_LAYOUTRTL
                else:
                    exStyle = exStyle | WS_EX_LAYOUTRTL
                windll.user32.SetWindowLongA(python_script_sci_handle, GWL_EXSTYLE, exStyle);
                

                You have to use SetWindowLongPtr where I use Get/SetWindowLongA as
                SetWindowLongPtr has not been transferred to wine.

                Cheers

                  Hello Claudia,

                  Thank you very much. This is beautiful!

                  I get the AttributeError: function 'GetWindowLongPtr' not found error.
                  What should I import from ctypes?

                    Hi Yaron,
                    you have to use either the ansi or unicode version

                    Unicode and ANSI names GetWindowLongPtrW (Unicode) and GetWindowLongPtrA (ANSI)

                    Same is true for Set…

                    Cheers

                      Hello again,

                      I get the same error.
                      No errors with Get/SetWindowLongA but the script doesn’t work. :)

                      Thank you.

                        can you do an test output to the console (preferred last line of code) and run the script at least two times. Let me check about the Set/GetWindowLongPtrW.

                        Cheers
                        Claudia

                          Claudia,

                          I had put the code in startup.py . I’ve now moved it to a separate script and run it twice.

                          default

                          can you do an test output to the console (preferred last line of code)

                          I’m not sure what you mean.

                          Aren’t you tired? Should we continue tomorrow? :)

                          Thank you.

                            Yaron,
                            no I meant using the GetWindowLongA as I did.
                            Btw. it looks like 32bit Python has to use GetWindowLong whereas 64bit Python
                            uses GetWindowLongPtr.

                            So make a normal script, use my code and print something to the console at the very end of the script just to see if the output is seen. If this is the case run another time and see if something changes. If so we have to change the logic about exstlye…

                            Cheers
                            Claudia

                              It does write to the console.

                                      Both exStyle = exStyle & (~WS_EX_LAYOUTRTL) and exStyle = exStyle ^ WS_EX_LAYOUTRTL do change the the layout.

                                      I have to clear the output first. Otherwise it’s gibberish.

                                      Thank you.

                                        Yaron,

                                        this seems to be my waterloo in terms of understanding bitwise operations.
                                        I always confuse when to use OR and when XOR.

                                        So, just to clarify, this works?

                                        if (exStyle & WS_EX_LAYOUTRTL):
                                            console.write('exStyle & WS_EX_LAYOUTRTL: {}\n'.format('exStyle & WS_EX_LAYOUTRTL'))
                                            exStyle = exStyle ^ WS_EX_LAYOUTRTL
                                        else:
                                            console.write('exStyle | WS_EX_LAYOUTRTL:{}\n'.format(exStyle | WS_EX_LAYOUTRTL))
                                            exStyle = exStyle | WS_EX_LAYOUTRTL
                                        windll.user32.SetWindowLongA(python_script_sci_handle, GWL_EXSTYLE, exStyle);
                                        console.write('test\n')
                                        

                                        Cheers
                                        Claudia

                                          and there seem to be a trap. The console changes it output only if something is
                                          written to the output. So the initial state will be RTL until something gets written.

                                          Cheers
