Detecting event for closing view [message #452684]

Hi everybody,

I would like to detect when a user clicks on the cross to close a view. I have tried IPartListener2 but the method "closedView" is called after the view has been closed. What I need is to prevent my view to close until I have performed some instructions. Could you please help me ?

Thank you,

Alex

Hi Alex,

have you tried to overwrite the #dispose() - Method of your Viewpart?

Most editors do this. When you close then and their is unsaved work they
will as to save or not or to cancel. Use debugber and find out how they do
the cancel.

Alas editors work because the platform expects them to have state - they
implement ISaveablePart and have PROP_DIRTY etc. Views do not have this so
that mechanism is not available to you.

I think Tom's idea of overriding dispose() is the only way.

You can have the behaviour of an unsaved/dirty editor in a view if you

implement the interface ISaveablePart2 in your view and pretend to be dirty:

: : :
: : :
public boolean isDirty() {
return mDirty;
}

public boolean isSaveOnCloseNeeded() {
return mDirty;
}

public int promptToSaveOnClose() {
mDirty = doWhateverYouWantOnViewClose();
return !mDirty
}
: : :
: : :

Although, you will always have the ugly "*" displayed on your view tab.
