How to prevent text wrapping in QPlainTextEdit?

[jameshibbard]

I have a QPlainTextEdit on which I wish to display a random combination of letters, numbers and special characters (a password, basically).

When the text is only letters and numbers, the output runs from left to right with no breaks (as one would expect). It only wraps when it hits the edge of the QPlainTextEdit.

passOutput.setPlainText(
  'AS0dlkqVDmC5L8mKhNAmVU7Ww2j9LiCFo6k43uR6lngZ0Prr2I1xRF7Y64PF92j87V'
);

However, if the text contains certain special characters an undesired line break is inserted. E.g.:

passOutput.setPlainText(
  '2VB#t>ZQyS.*|t`=t=AdB=s9gyNKt%Up9q:fKpL]DKB-5:g),cneAg4(bH:A9hF/cH'
);

Notice the line break after the | character.

My question: is there any way to prevent this?

I would like the text containing the special characters to run from left to right and only wrap when the edge of the QPlainTextEdit is reached (like the example containing just letters and numbers).

I tried styling the QPlainTextEdit using word-break: break-all, but it didn't make a difference.

Looking through the QT docs, I did find this: https://doc.qt.io/qt-5/qtextoption.html#WrapMode-enum

Is something like wrap mode available in NodeGUI?

Hey @jameshibbard I have a pull request addressing your requirements here. This will be available in the next release.

Thank you @master-atul! I really appreciate the quick response and look forward to the next release.

There are two remaining things which I still need to implement in my app. I would have opened issues to ask about the best way of implementing them, but I'll mention them here, as maybe there's a chance that one or the other of them also makes the next release.

1. I'd like the ability to set the title of the window. As you can see from the screenshots above, it is qode by default. I'd like to set it to be something different. I've tried the widget.setWindowTitle() method, but it didn't work (the window title remained unchanged). Is it possible that it hasn't been implemented yet?

2. I'd like to implement a "Copy to Clipboard" function. Would this be the QClipboard Class in QT?

Once again, thanks for your help. When I'm done building this demo app, I'm intending to write a tutorial demonstrating how to make a password generator with NodeGUI. I'd love to help get the word out about this library!

Hi @jameshibbard

1. You can call setWindowTitle from window instance and that should work as expected.

2. Awesome, I ll see if I can push the QClipboard class also in this release otherwise it would be in the next.

Also, if its not too much to ask, once you are done writing your app can you provide me a link to it so that I can mention it in the Readme or examples of this project. 😄

1. Oh nice. That didn't work last time I checked, but all good now 😄

2. Thank you!! Any idea when the next release will be?

Also, if its not too much to ask, once you are done writing your app can you provide me a link to it so that I can mention it in the Readme or examples of this project.

Absolutely. I can also provide you a link to the tutorial if that helps.

If there's anything about the code that could be improved, please let me know.

[a7ul]

Awesome!! Thanks @jameshibbard
I will add a link to this in the README :) If you manage to write a tutorial for this I will link it too once you have posted

[jameshibbard]

No worries. Will might take a couple of weeks, but I will a) definitely write this, and b) keep you posted 😄

[jameshibbard]

Hey @master-atul, I got the tutorial done. You can find it here: https://hibbard.eu/node-gui/

Grateful for any feedback, esp. if anything can be improved.

Thanks @jameshibbard. The blog is really nicely written and represents the project accurately. I have added the link on the README :) Cheers.

Happy to help. Thanks for the link in the README :)
