bypass physical <<paste>> event
in [TCL]

From: JFisher on 12 Jun 2010 21:39 Hi All, Perhaps someone out there in cyberspace can help me with this one... I'm working on a Windows XP machine and trying to evoke a function before a physical <<paste>> event. More specifically, I'm trying to execute a function AFTER a <<paste>> event using a <Control-v> bind and having no success; the function unfortunately runs before the <<paste>> event occurs. I've tried a break command at the end of the function with no success. Is there anyone out there that has tackled this problem? Any help with this is greatly appreciated. Long live open source programming, Jason

The trick is that, even when you set up an "additive" binding (concatenated to the existing one) by starting it with "+", it will only concatenate itself to the script for this bindtag (which may be ".t", eg the widget's name, but also "Text", ".", or "all" -- see bindtags.n), so it might not be "after" the one you want. To introspect that, use the 1-arg [bind] and see where the relevant code is hooked. In the case of the Text widget, we can see that [bind Text <<Paste>>] returns: tk_textPaste %W As a consequence, you'll get your post-paste hook by saying: bind Text <<Paste>> {+mystuff} -Alex
