<div class='writeup-body'>とばかり is a construction that is often used to show that something is being done 'as if to say (A)', or 'seeming that (A)'. It is a combination of the case-marking particle と in its 'quotation' use, and the adverbial particle ばかり, exhibiting that something is 'basically exactly as described'. Due to this, とばかり simply indicates that while (A) is as described, it is not literally the case. 
とばかり can appear after almost any word, as the と is creating a quote. に will often follow ばかり when the sentence is going on to describe what is actually happening.<ul class='writeup-examples--holder'>
