Window closing event in compare editor [message #449078]

Hi,

I am using the Eclipse compare editor to compare two text files. To open the
files in the compare editor, I use CompareEditorInput to prepare the input
and the CompareUI.openCompareEditor(input) method to display the files. I
have even got the save routine working whenever the files are changed. Now I
want to set/reset a persistent property for the files whenever the compare
editor is closed by the user. However, I am not able to come up with a way
to trap the window closing event from the compare editor. Thought this must
be straightforward ... maybe I am missing something here. I am invoking the
openCompareEditor() method like this:

window.getShell().getDisplay().syncExec(new Runnable()
{
public void run()
{
CompareUI.openCompareEditor(input);
}
}); // (window is the active workbench window)

Any thoughts on how I might be able to trap the window closing event from
the compare editor ?

Thanks in advance.

Hi,

Well I figured it out :-) You need to implement IPartListener and register
the listener using the addPartListener() method in IWorkbenchPage. You can
trap the window closing event using the partClosed() method in the listener
and by checking to see if the call was triggered by the compare editor.
