creating a subclass in system browser

Hi

is there a way I can create a subclass when I have selected a class in the
System Browser class list (top 2nd panel).

Couldnt see any option - Or is it that no such feature is needed

Thanks

Sorry I missed it.
(I did not expect it in refactorings)

Re: creating a subclass in system browser

I'm not surprised you missed it. I think it's not very intuitive having it on
the refactoring sub-menu - especially when you already have "new class" on
the right click menu when you select a class. Why not have "create subclass"
there as well?

By the way, did you have trouble working out the "normal" way of creating a
subclass? You select the class definition tab in the browser bottom panel
and press the + (plus) button. It took me ages and ages to work that out. Am
I just slow or is that also counter-intuitive?

Re: creating a subclass in system browser

No, I was not aware of the "+" in class definition tab. actually it's not there (yet) in Pharo 9 Win 64 which I am using.

In reply to this post by kmo

Now I'm wondering if I'm doing something wrong, or short-circuiting the correct approach...

When I want to subclass - I simply select the class, and update the class definition page - moving the subclass name (which is the current class) to the class section, and replacing the subclass name with my new subclass name. I can also take care of instance and class variables I need... just save and everything seems to work just fine.

Is there a reason to need to do this with a menu? Many times with menu options I'm unclear WHAT it's operating ON :)

Nice to know there are multiple ways to get things done in Pharo!!

Re: creating a subclass in system browser

Doing it by hand is fiddly and error-prone. I know - because that's the way I
used to do it before I realised that the plus button at the top of the
browser bottom panel did it for me. (I had no idea that there was also a
menu option on the refactorings menu). I think you might find the button to
be the better way - I did.

Can you send a screenshot of the plus button? I'm using v9 on MacOS and I don't see a class + button...

Re: creating a subclass in system browser

One thing I find challenging when teaching Pharo to new students -- especially those accustomed to IDEs with files, which is pretty much all of them ;) -- is that there are sometimes menus (depending on the Pharo version) to add a new package, new class, new protocol, but not a new method, etc.

For onboarding new users, I think it's important that these things be intuitive and consistent, especially since updating tutorials takes time. They are super important because inconsistencies become barriers to onboarding new people. My point here is not that a menu option necessarily exists, but that we have a consistent way to explain how to create things even when Pharo changes. Apple used to have 10 commandments for keyboard shortcuts, and I think a similar idea could apply to having consistency in these elements of Pharo.

Thanks Sanjay... I don't use v8. I'm heavily invested in Spec2 and, well, my apps won't run in v8 :)

Ah, in my v9 version, I see a red circled exclamation point (hovering says 'Refactorings' - which has a menu for the +New subclass.

Good to know! Thanks!

subclass appears in the browser class definition tab.

This is from Pharo 9 on Linux (this is an older version 9 - not the very
latest)

That sounds completely horrible. Surely that's never going to remain in the
official release.

It's been there as a refactoring for a while. Why a refactoring? Who knows...

I hadn't actually noticed the "+" sign but it was there in V7 and is there in V9 on Windows.
