sorry if my title is confusing, but I am confused. I'm working with the Tk::TableMatrix widget to edit tabular data, though my problem may not be specific to that widget. Apparently in Tk::TableMatrix the event <Control-Key-v> has a default binding to a callback that performs a paste operation. I don't know if this is an inherited binding or what: the documentation for Tk::TableMatrix makes no mention of it and I am, as they say, a total Tk newbie. That "built-in" paste function works great and I don't want to have to write my own. But I need to know when a paste operation begins and then when it is finished. Idealy, I think, I would create my own callback bound to <Control-Key-v> within which I could call the "built-in" paste function. But I can't find any documentation on this paste function, nor can I figure out any other way to call it other than generating the event: <Control-Key-v>. I know you can have multiple callbacks bound to the same event. And that the callbacks are executed in a certain order according to their 'specicifity'. So maybe I could construct two bindings such that one would run right before the default <Control-Key-v> callback and the other one right afterwards, but that seems messy to me. I think it wreaks. So does anybody know if there is some sort of $widget->paste() function that Tk::TableMatrix is calling that I could call too? Or am I thinking about this the wrong way? Or do I need to be more specific? (by the way, the reason I want to know when a paste operation is in progress is so that my I can capture mulitple cell edits. I'm trying to build some Undo functionality into Tk::TableMatrix, and I want a multiple cell edit (such as with "paste", "cut", or "replace all") to be an atomic undo.) Thank you so much, I hope this isn't a topic that's been broached and answered previsouly, I searched a little bit and really didn't see anything that seemed to match.
