NSMenuItem and NSPopOver

问题

On OS X app, what is the technique to show a NSPopover when the mouse is over a NSMenuItem (like in spotlight for example).

Thanks a lot!!! Christopjhe

I know it's been a while, but if you still haven't found a solution:

Register your class as a NSMenuDelegate to the menu that contains the NSMenuItem, and implement

- (void)menu:(NSMenu *)menu willHighlightItem:(NSMenuItem *)item;

then show the popover when this method is called.

Can you show your code in the question? It would make it easier to help you. But without knowing what your code looks like, this might work for you:

Add this to your statusItem

self.statusItem.action = @selector(clickStatusBar:);

Add method similar to this to make the popover appear

- (void)clickStatusBar:(id)sender {
    [[self popover] showRelativeToRect:[sender bounds] ofView:sender preferredEdge:NSMinYEdge];
}
