"paste" listener on a SWT widget

Question

I have an application with a SWT widget, say a org.eclipse.swt.widgets.Text, and want to add some control to the paste function.

The idea is that if the user can paste a string of IDs, I detect that, run some code and paste the object that corresponds to the IDs.

So I'm looking for some "ClipBoardListener" of some sort to add to my widget, but that doesnt seem to exist. A keylistener would only trap the pastes done by key and then you would have to deal with different key combos for pasting in different OS's.

Based on this java 1.2 question I tried subclassing the text class and override the inser method, but that didnt work

Exception in thread "main" org.eclipse.swt.SWTException: Subclassing not allowed

Seemed like an ugly solution anyway.

Answer 1

There's a ModifyListener which you can listen to. It doesn't distinguish between typed text and pasted text, but based on what it seems you want to do, that might work as well.
