A few comments to start on this huge PR:

• when there is only one elt in the proposed choices (from the pattern filtering) it would be nice to just press enter to use it. As it is, one has to use the down arrow key or the mouse click
• for emoji, you should include a space just after the emoji otherwise it breaks the emoji representation
• could not see any difference in your wordwrap example

I agree, I changed it to have a behavior close to an IDE. The first item proposed is selected by default. Pressing Enter/Tab will autocomplete it (Tab only works well with QPlainText though)

• for emoji, you should include a space just after the emoji otherwise it breaks the emoji representation

I removed them and I changed the example with more standard Unicodes. The issue with the emojis is that they consist of multiple characters which make the whole identification struggle.

• could not see any difference in your wordwrap example

I updated the example, it should be more explanatory now.

@malik-irain could you have a go to check this as well and merge it if it is fine. We have to move on to the monorepo ...

[malik-irain]

I know that's what's the doc says about subclassing WidgetParameterItem but I would be careful about monkeypatching qt methods as it already made tests fails without any apparent reason. I would have implemented a value attribute and a setValue method in PatternPlainTextEdit widget that call toPlainText and setPlainText. For the signal, it might be tricky.

Anyways for now, it works so we can leave it like that

[Ashwolaa]

I can add this if you think it is better. There is no impact on the tests.

Not sure, how to deal with the signal though.

Claude calls it "Duck typing adapter"

[malik-irain]

Yeah it works very well in python, but when using objects from C++ it can lead to segmentation faults (we had the issue recently), but as it doesn't seem to make tests fail, it's ok with me!

@Ashwolaa Can you rebase or merge the last modification of pymodaq_gui in you PR so that I can see if tests are passing?
