gtkmm and the system clipboard

I am wondering if there is a signal anywhere in gtkmm that is emitted when the system clipboard contents change/someone copies text. I looked into the gtk docs and it seems the only signal emitted by the Gtk::Clipboard object is the owner_changed signal. To be more specific, I don't care who changes the system clipboard whether it be my app (which it wont be) or the user.

My only other option to implement this is t开发者_开发技巧o loop and keep checking the clipboard for a change. Was hoping there was a more efficient means of accomplishing this.

Anyone know of a signal?

Thanks.

I'd take a look at this example. I did not compile and run it, but I think it is indicating that the "owner_changed" signal will do what you want.
