      @Michael-Vincent

      I tried your recent (August 2023) scripts and both of them failed because they can’t find the import when you do import requests.

      The builtin urllib.request module should be available to any Python 3 host. You can then do the JSON serialization with the builtin json module. I can’t test it at the moment, but a more portable script would look something like this:

      -import requests
      +import json
      +import urllib.request as requests
      +import urllib.parse
      # . . .
       from Npp import editor
      
               """Lookup the word."""
               self._initialize()
      
      -        text_encoded = requests.utils.quote(self.word.getText())
      -        r = requests.get(f"http://api.dictionaryapi.dev/api/v2/entries/en/{text_encoded}")
      -        if r.status_code != 200:
      +        text_encoded = urllib.parse.quote(self.word.getText())
      +        r = requests.urlopen(requests.Request(f"http://api.dictionaryapi.dev/api/v2/entries/en/{text_encoded}"))
      +        if r.status != 200:
      +            r.close()
                   return
      
               synonyms = []
               antonyms = []
               response = ""
      -        for idx, defs in enumerate(r.json()[0]['meanings']):
      +        for idx, defs in enumerate(json.loads(r.read().decode('utf8'))[0]['meanings']):
                   response += f"{idx+1} : {defs['partOfSpeech']}\r\n"
                   for pos in defs['definitions']:
                       response += f"    {pos['definition']}\r\n"
      # . . .
               self.ret.antonyms = sorted(set(antonyms), key=str.casefold)
               self.synonyms.addStrings(self.ret.synonyms)
               self.antonyms.addStrings(self.ret.antonyms)
      +        r.close()

        I must be doing something wrong in a really basic sense?

        The only thing you did wrong was to assume that once the author changed the public API interface, he would also change the examples in the documentation, but … man … he screwed up :-)

        on_click != onClick

          It works better that way. :-)

          Probably the code in test_different_ways_to_create_dialogs.py in the __test__ folder needs the same change?


          One more oddity: With the aformentioned test_button.py script, I have to press the Close Dialog button TWICE before the script ends.

          It seems that the dialog IS closing with the first press, but something is reopening it?

            Your changes did indeed allow the dictionary-lookup script to run for me. Thanks!

            For others that might be interested, here’s a full version of Michael Vincent’s dictionary script with rdipardo’s changes:

              Something is definitely up with having to close things twice.

              When trying out various scripts from the __test__ folder, e.g. test_progressbar.py, test_statusbar.py, I have to press the X in the upper right of the window TWICE before the script truly ends.

                Yeah, lol, apparently my code isn’t really self-explanatory, too bad, was hoping it was.
                Each test_{control} script executes once the dialog by rc-generation and once as a class example.

                  Ha, okay, I wasn’t really digging into any of the code (yet!), just running things like a dumb user (success!) and misunderstanding what results were obtained.

                  Thanks for the clarification.

                  What I like to do if I have code that runs two ways is to let it only one way run via a controlling variable at the top. That way someone trying it can change one line (to change the variable) and the rest will run differently.

                    @rdipardo

                    Sorry I haven’t been around in a while, just getting back now. Thank you for the updates; I’ve converted my dictionary and translator scripts to use the more portable method as urllib does indeed come with PythonScript. And yes, I have the PythonScript plugin set to “see” my installed Python3 - which had the requests module installed.

                    Happy we’re getting some traction out of @Ekopalypse 's Dialog-wrapper - truly ingenious and adds lots of menu / dialog functionality to PythonScripts.

                    Cheers.

                      Yes, correct and done, thanks for pointing it out.

                      What I like to do if I have code that runs two ways is …

                      They are tests, actually not meant as examples, my point was rather,
                      that the dialogs generated in each case, or more precisely, the resulting ByteArrays are compared,
                      but I understand what you mean. If I have a little more time sometime in the future,
                      I will tackle that.

                      Right now I’m using my meager free time to get the NppLspClient plugin into beta status, and then I wanted to rewrite the NppDebugger because my employer won’t allow me to release the existing plugin.
                      (The downside, if you develop something during working hours, suddenly it doesn’t belong to you anymore) :-(
                      (The advantage is that I can learn and use a new language, probably Rust or Zig, but I don’t know for sure yet) :-)

                        Without a specific set of examples, the tests become the examples. :-)

                        Actually, I think Michael led me down the road of the tests being examples…I didn’t think too hard about it at first.

                        (The downside, if you develop something during working hours, suddenly it doesn’t belong to you anymore

                        It is reasonable that it doesn’t belong to you, but it seems unreasonable that your employer won’t release it. It would be understandable if your employer was a developer of rocket fuel and your plugin calculated optimized rocket fuel ingredient proportions… But as a general purpose tool that won’t give a competitor some sort of edge, why not share it? Sigh.

                          Not to get too far off-track with this thread, as it’s meant to highlight the Little Dialog-wrapper, but I noticed that in your “dictionary” script, if the selected “word” to look up isn’t spelled correctly (such that it isn’t a real word), unhandled exceptions occur (just check the PS console window).

                          Before I noticed this I got to thinking about the utility of dictionary programs. They’re fine if you know how the word is spelled and you want other info about it. But if you don’t know the spelling, it is hard to get you where you need to go.

                          Perhaps the script, if it doesn’t get an exact match, it should do a web search on the word of questionable spelling, e.g. N++'s Edit > On selection > Search on Internet. From that output, the user could correct the spelling input to the script and get further info about the word.

                            Indeed. Quick fix:

                                        r = requests.urlopen(requests.Request(url=f"http://api.dictionaryapi.dev/api/v2/entries/en/{text_encoded}", headers=headers))
                                    except urllib.error.HTTPError:
                                        notepad.messageBox('No definitions found.  Perhaps misspelled?', 'Error')
                                        self.terminate()
                                        return
                                    if r.status != 200:

                              So I was attempting to do something “real” with the Little Dialog Wrapper, and it fell a bit short in capability in a couple of areas.

                              I’m not complaining, mind you, I just thought I’d share my findings. And, of course, I could be doing something wrong that is indeed quite simple to do correctly.


                              I wanted my dialog to start up with a checkbox in the checked state and I found no easy way to do it. I tried the obvious:

                              self.my_checkbox.setCheckState(BST.CHECKED)

                              right before the call to self.show(), but this did not achieve the goal.

                              The workaround that I came up with that did work was:

                              import threading
                              threading.Timer(0.25, lambda : self.my_checkbox.setCheckState(BST.CHECKED)).start()


                              I also found no obvious function (meaning part of the WinDialog hierarchy) to call to disable a control. With a little ctypes help I worked around by doing:

                              from ctypes import WinDLL
                              user32 = WinDLL('user32')
                              user32.EnableWindow(self.my_checkbox.hwnd, False)

                              And again, this didn’t work if I wanted to start up with a control disabled. So I resorted to:

                              threading.Timer(0.25, lambda : user32.EnableWindow(self.my_checkbox.hwnd, False)).start()

                              for that.

                                        self.label  = Label(         title='Filter for:'         , position=(10, 12),  size=(30, 11)  )

                                        self.case   = CheckBoxButton(title='Case &Sensitive'     , position=(45, 30),  size=(80, 14)  )
                                        self.regex  = CheckBoxButton(title='Regular E&xpression' , position=(145, 30), size=(80, 14)  )
                                        self.cancel = Button(        title='&Cancel'             , position=(190, 55), size=(50, 11)  )
                                        self.reset  = Button(        title='&Reset'              , position=(45, 55),  size=(50, 11)  )

                                        self.cancel.onClick = self.on_cancel
                                        self.reset.onClick  = self.on_reset
                                        self.case.onClick   = self.on_case
                                        self.regex.onClick  = self.on_regex
                                
                                        self.show()
                                
                                    def initialize(self):
                                        self.edit.setText(self.ret.user_input)
                                        SendMessage(self.case.hwnd,  BM.SETCHECK, self.ret.IGNORECASE, 0)
                                        SendMessage(self.regex.hwnd, BM.SETCHECK, self.ret.REGEX, 0)
                                

                                This is the “relevant” parts of a larger script - my version of your filter lines editing actually.

                                I create an object to store the values so then I can return them and save them in the global PythonScript object so next time I call it I can set the checkboxes appropriately. The initialize() function does the checkbox-ing.

                                Cheers.

                                  @Michael-Vincent is correct, to quote from the Dialog help

                                   |  initialize(self)
                                   |      Initializes the dialog and its controls at runtime.
                                   |      
                                   |      This method is intended to be overridden by a concrete class.
                                   |      It is executed after all controls have been created but before the dialog is displayed.
                                   |      Concrete implementations should provide custom logic to set up initial values, states, and configurations of the controls.
                                  

                                  It might be worth adding function(s) to enable or disable controls, yes. PRs are welcome :-)

                                      This is interesting. How do you kick off the saving of the current values? Meaning, if user presses Esc to close the dialog, or presses the red X in the title bar of the dialog, are you able to capture this and save your current control values? Maybe in your script you wouldn’t want to save in these circumstances, but OTOH maybe you would…

                                        You have an initial state when you start the dialog and from there I would use the control events to get the values you need. Something like

                                        from WinDialog import Dialog, CheckBoxButton
                                        from WinDialog.controls.button import BST
                                        
                                        class Example(Dialog):
                                            def __init__(self):
                                                super().__init__(size=(100, 100))
                                                self.counter = 0
                                                self.btn1 = CheckBoxButton(title='Click me', position=(35, 40), size=(50, 14))

                                          @Ekopalypse said in Little Dialog-wrapper for PythonScript:

                                          … use the control events to get the values you need.

                                          Sure, but that’s the obvious case.

                                          That’s why I specifically asked MV “…if user presses Esc to close the dialog, or presses the red X in the title bar of the dialog…”

                                          As far as I can tell, and yes I’ve read some of the docs now :-), these aren’t capturable events?

                                            BTW, I sort of missed this at first from the github page:

                                            help(WinDialog)

                                            I guess I’m just not used to documentation being provided in only this way, at least not any more. It’s totally fine, though, just maybe not super obvious for a newbie (would there be any newbies wanting to experiment with LDW??).

                                            So maybe I’ll offer this on the off-chance that a newbie is reading; this is what I did to make it easier to refer to (note: nothing rocket sciencey here…):

                                            • go to PythonScript console window area, right-click, and choose Clear from the popup menu
                                            • at the >>> prompt, type import WinDialog and press return
                                            • type help(WinDialog) and press return
                                            • right-click again and choose Select All and then press Ctrl+c
                                            • create a new tab in Notepad++ and paste there
                                            • save the tab for later reference
