macOS what method is invoked when dock icon is clicked?

[TurboLag]

After the user clicks the red close button on my application, I would like the window to re-appear when the icon in the dock is clicked. I have created the method to re-show the window in the menu bar, but I would also like an icon-click to invoke the same method.

What method is invoked when the icon is clicked?

Check the NSApplication class documentation for:

- (BOOL)applicationShouldHandleReopen:(NSApplication *)theApplication hasVisibleWindows:(BOOL)flag

For anything like this, the first places to look are usually NSApplication or NSDocument IMHO.
