PreferenceModule is hidden

[Fabian Jäger]

Dear Mail experts,
is there a method that gets called when a PreferenceModule is hidden, meaning that another PreferenceModule is selected by the user?
I would like to save changes made to my plugin's preferences when the user leaves those preferences.

Best regards,
Fabian

Hi Fabian,

I think that there is a mechanism explicitly designed to check if changes are saved. (You can find out by tracking what happens if there are unsaved changes in the account preferences.)

I do something simpler, though, to detect if the preference module is switched from. If you also want to handle the case when the whole window is closed (which I do not handle), removing the [[self window] isVisible] part should work.

So this is what I do: I have my settings displayed in a NSBox subclass that implements this method:

- (void) viewWillMoveToSuperview: (NSView*) newSuperview{
if( newSuperview == nil && [[self window] isVisible] ){
// do stuff
}
}

Dear Adam,
thanks a look. The described approach works like a charm!

Best regards,
Fabian
