Can the resource editing tool handle this

This depends on the tool you use, ResourceHacker doesn’t seem to be able to do this. But the idea is rather that you use the design tool until you are satisfied with the result and then copy the generated code into the Python script to reuse it.
If you need to add an additional control at a later time, then all you have to do is copy the newly generated line.

This is intriguing but …

Of course, these dialogs would not be modal and you have to be careful about the objects you create, i.e. don’t use these objects for something else or delete them, but that is already the case today as well.

Sure, easy enough for one control, one line.
I was more thinking about how I tend to do things… on a greater than 1 line basis. :-)

but that is already the case today as well.

Today we don’t have to think about script concurrency, because PS mostly prevents it. Anyway, just thought I’d raise the question.

Ekopalypse

@Alan-Kilborn

oh no, it’s not a concurrency issue, it’s more like the callbacks we use today - event driven.
The script starts the dialog and ends. But the class that manages the dialog stays active until the dialog is closed.

And then I thought, what if … trailer … :-D

Any alpha / beta version ready to test yet? I keep checking your repo but don’t see any new commits. I have a pretty easy use case in mind - an edit box with checkboxes for regex and case insensitive - all for a filter search lifted from @Alan-Kilborn 's work!

Integrating my supreme Notepad++ experience by standing on the shoulders of giants!

Hi, I have quite a lot on my plate privately at the moment, but I promise to upload a new version this weekend.
It’s actually going quite well and if you stick to what’s currently implemented, there shouldn’t be any difficulties. Sorry for the delays.

Ekopalypse

@Michael-Vincent

Repo has been updated, but be warned that I’m not completely satisfied yet, which means it’s not API stable. Further updates could break things that currently work.

Ekopalypse

@Michael-Vincent

There was a typo that prevented the dialog from being created.
I should have tested it before, sorry. Is fixed now.

@Ekopalypse

Great! I have my small example:

from WinDialog import Button, Dialog, CheckBoxButton, Label, TextBox
from WinDialog.controls.button import BM, BST
from WinDialog.win_helper import SendMessage

user_input = ''
REGEX      = True
IGNORECASE = True

class FilerLinesEditDlg(Dialog):
    def __init__(self):
        super().__init__(            title='Filter Lines Editing', size=(250, 75), center = True)
        self.label  = Label(         title='Filter for:'         , position=(10, 12),  size=(30, 11) )
        self.edit   = TextBox(                                     position=(45, 10),  size=(195, 14) )
        self.case   = CheckBoxButton(title='Case Sensitive'      , position=(45, 30),  size=(80, 14)  )
        self.regex  = CheckBoxButton(title='Regular Expression'  , position=(145, 30), size=(80, 14)  )
        self.ok     = Button(        title='OK'                  , position=(130, 55), size=(50, 11)  )
        self.cancel = Button(        title='Cancel'              , position=(187, 55), size=(50, 11)  )

        self.ok.on_click     = self.on_ok
        self.cancel.on_click = self.on_cancel
        self.case.on_click   = self.on_case
        self.regex.on_click  = self.on_regex
        self.show()

    def initialize(self):
        global IGNORECASE
        global REGEX
        SendMessage(self.case.hwnd, BM.SETCHECK, IGNORECASE, 0)
        SendMessage(self.regex.hwnd, BM.SETCHECK, REGEX, 0)

    def on_ok(self):
        global user_input
        user_input = self.edit.get_text()
        self.terminate()

    def on_cancel(self):
        global user_input
        user_input = None
        self.terminate()

    def on_case(self):
        global IGNORECASE
        check = SendMessage(self.case.hwnd, BM.GETCHECK, 0, 0)
        if check & BST.CHECKED:
            IGNORECASE = True
        else:
            IGNORECASE = False

    def on_regex(self):
        global REGEX
        check = SendMessage(self.regex.hwnd, BM.GETCHECK, 0, 0)
        if check & BST.CHECKED:
            REGEX = True
        else:
            REGEX = False


FilerLinesEditDlg()

print(f"User:  {user_input}")
print(f"Case:  {IGNORECASE}")
print(f"Regex: {REGEX}")

It seems to run correctly and prints status to the PythonScript console. I plan to integrate this into a larger script.

I’m not sure I did the checkbox stuff correctly. It works, but I had to import some extra classes and the SendMessage function from your helper library. Did I do this right?

Cheers.

Ekopalypse

@Michael-Vincent

You can do it this way, but I personally would put the globals as attributes in the class to avoid globals in the first place.
For the GETCHECK, because the checkbox is a “boolean” value, I would do something like: …

...
    def on_case(self):
        self.IGNORECASE = not self.IGNORECASE
...
dlg = FilerLinesEditDlg()

print(f"User:  {dlg.user_input}")
print(f"Case:  {dlg.IGNORECASE}")
print(f"Regex: {dlg.REGEX}")

As for the SETCHECK, the SendMessage function is currently required.
The next version, uploaded this weekend, will have a checkbox button method setCheckState (that’s the same kind of naming PS does … so it seems to make the most sense, right?). And now that I think about it, getCheckState makes sense too because of the 3-state checkboxes. Also, the next version will be able to handle IDOK and IDCANCEL, which means you can close a dialog with ESC and trigger the execution of the edit with ENTER.

This just keeps getting better!

I updated the globals to a return class that I pass in and then examine on output. The issue is I want this as a prompt in a larger already existing PythonScript and class so the “globals” are just globals in this example - in my project, they are attributes of the existing class that the dialog will need to know to set on startup and then return in case of modifications in the dialog. The globals were just a “cheat” way to illustrate a “complete self-contained example” to post here. But point taken - I am avoiding globals in the finished product.

The on_case recommendation works as well very nicely and certainly simplifies code - removes the need for me obtaining BM.GETCHECK as well.

It’s Memorial Day weekend in the States so I’ll be stepping away from all this for the long weekend. I do hope you take time to relax this - and any weekend for that matter. I’m in no rush for the updates, but will keep checking back the repo to see when they in fact do arrive.

UPDATE:
The updated script from above with fixes discussed. Also add the c#_ prefixes to the controls to force the TABSTOP order - seems to be alphabetical:

Don’t worry, the weekends are for family commitments. I’ll just publish what I’ve managed to do during the week.
As for the WS_TABSTOP, I thought that the order of creation of the controls determines the order … I’ll have to check that.

@Michael-Vincent said in Little Dialog-wrapper for PythonScript:

Confused me at first; I’m wondering what the heck C# has to do with this…

Finally I notice this is what you meant:

Ekopalypse

@Michael-Vincent

The issue is here. dir always returns a sorted list.

Replacing it with for item in self.__dict__.keys(): seems to behave as expected. The first control created that has the style ws_tabstop gets the initial focus.

Ekopalypse

First beta version released.
Sorry for breaking existing code, but from now on this should not happen.

The current state of the project is what I currently support.
If you encounter issues where the dialog box or controls do not work as described or advertised,
please report them by submitting a “git issue”. I will diligently investigate the issue and work on a solution.

However, please note that any requests for additional functionality beyond what is currently offered will be considered feature requests.
While I appreciate user feedback, I prioritize implementing features that benefit me personally and align with the overall goals of the project,
which is to be a simple wrapper over DialogBoxIndirectParam Windows API.
Thank you for your understanding."

I’m just starting to experiment with this “Little Dialog wrapper”…

@Michael-Vincent said in Little Dialog-wrapper for PythonScript:

nice demo in WinDialog_tests_\test_win_dialog.py

Actually, I think, from the screenshot, that it is ...\lib\WinDialog\__tests__\test_button.py that is being run, NOT test_win_dialog.py.

When trying either of the two basic examples HERE, I get a dialog that appears and looks like this:

But clicking on the Okay button doesn’t print anything to the PS console window (as the code makes me believe it should) and clicking on the Close Dialog button doesn’t close it (only clicking on the X in the upper right corner will end it).

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

@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. Probably you are running with Prefer installed Python libraries?

I don’t have an “installed” Python, but I have a portable Python 3.11.4. I wonder what it takes to make Notepad++ see and use that…

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()

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

@Ekopalypse said in Little Dialog-wrapper for PythonScript:

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?
