Re: How Do I get informed when -showHelp: has been called?
Thank you all for pointing me to the solution of my question.
My first thought was that you could change the target of the menu item
so that it calls your own method, then call the original
showHelp method with something like:
[NSApp showHelp:sender]
This is what I did now, using an own -myShowHelp: method which calls
[NSApp showHelp:sender], when other things have been prepared. This of
course opens the Help Viewer. No need to subclass NSApplication and to
override showHelp: at all.
- (IBAction)myShowHelp:(id)sender
{
[... do some stuff];
[NSApp showHelp:sender];
[... do some other stuff];
}

I would really like to get a hint on this. Even a simple not possible would help.

Which other way can I use to receive any information when -showHelp: has been called? TY in advance, ---Ulf Dunkel I'm curious what you're trying to achieve here. My first thought was that you could change the target of the menu item so that it calls your own method, then call the original showHelp method with something like: [NSApp showHelp:sender] This still might not actually display the help viewer for example if it had been removed from the system, or if something made it crash before it displayed. I'm not sure what happens in those cases (an error in the log, or does it display an error alert?) Not very likely perhaps though. If you have to be more certain you might be able to view the active process list and observe whether it contained the help viewer after the call to showHelp. Alternatively maybe run a web server inside your app and make the help page load some object from it? It depends on how certain you want to be I suppose. :-) Perhaps others might have better ideas or could suggest another way of doing it.

Which other way can I use to receive any information when -showHelp: has been called? What makes you think -showHelp: (in NSApplication) can not be overridden? Works fine here. The possibly confusing part when subclassing NSApplication is how to make your app use that subclass. Typically this is done by setting a custom class (your subclass) to the Application object in the MainMenu nib file.
