Easy way to override a method?

Is there an easy way in Squeak to override a method?

I have created a subclass of a class, and am viewing my subclass in a hierarchy
browser. I have clicked on the superclass in the browser and am browsing
methods to see what I need to override.

Having discovered a method that I want to override - I was hoping I could
right click on that method and select Refactor|Override - but its not there
(it is in Dolphin). Failing this I tried drag and drop - but that seems to
just move the method (I held the Control key while dragging but I guess thats
a Dolphin and a windows thing).

Is there some way to easily and quickly do this without having to cut and
paste?

Tim

Hello Tim,

if I don't misunderstand you, you just redefine it in your subclass?

RB uses the shift key to copy a method into another class instead of
moving it. Other refactorings are push up, push down moving the method
down to every subclass.

Hi Herbert,

Yes but its a nuisance to copy the method signature, click on the class below,
click on a method (or the as yes undefined category), and then paste the
signature and then enter by override.

I was hoping that there was something like in dolphin - browse my subclass
but enable show inherited methods - select the inehrited method, right click
and pick Refactoring | Override - this then does then creates me a template
that overrides.

The shift key wasn't one I thought of - that is a reasonable workaround if
a bit mousy. Maybe if I get better at Squeak I will work out how to add a
keyboard shortcut.

Thanks for the tips.

Using eCompletion, if you know which method to override you can simply
start typing the first few letters of the selector, then press
CTRL+space and select the method from the popup window.

to show a class with some of it's inherited methods, use the
protocol browser (select a class, and alt-P). When you save a
method in the protocol browser, it asks you which class to save
it under, if I remember correctly.

I'm surprised no one has mentioned the "copy up or copy down..."  
feature, available in the "more..." branch of the selector-list menu  
of any browser or message-list of most versions of Squeak since March  
2001.
