Leer at a rounded leg, perhaps (4)

I believe the answer is:

ogle

I'm a little stuck... Click here to teach me more about this clue!

'leer at' is the definition.
(I've seen this before)

'a rounded leg perhaps' is the wordplay.
'a rounded' becomes 'o' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'perhaps' indicates an anagram.
'leg' anagrammed gives 'gle'.
'o'+'gle'='OGLE'

Can you help me to learn more?

(Other definitions for ogle that I've seen before include "Eye lewdly" , "Eye lecherously" , "View lecherously" , "as lecher might do?" , "Lasciviously look" .)

I've seen this clue in the Evening Standard.
