Well if you are planning on using an NSMenu, or something with just text
menu items, you should use NSStatusItem's setMenu message. In this
case, you would forgo using the custom view entirely. On the other hand
if you want to be more complicated and have a menu with something like
a slider in it, then you will need to override NSView's mouseDown
message. In your implementation, you will need to write your own event
loop to handle the events. See the apple docs for more info on this and
a good sample event loop to start with.

Wow, that is seriously informative. Thanks!!! Now if only I could
figure out how to get the menu to appear too. ;-)
The NSMenu's popUpContextMenu doesn't quite work right if I set the
point argument to just below the menubar.
If I can figure this part out, I can get rid of my NSMenuExtra (gladly)
completely.
You've been so helpful, I feel bad asking. But any ideas?
Thank you,
Sanford

If you draw your custom view in the status bar(or anywhere else), the
aqua window pattern will show through it. To highlight it, call this
method:
[[NSColor colorWithDeviceRed:.2 green:.4 blue:.8 alpha:1] set];
then:
NSRectFillUsingOperation([imageView frame], NSCompositePlusLighter);
where imageView is the custom view that you are working with.
If you are really picky you can tweak the color a little to have it
match the true system highlight color. There should be a way to
figure it out programaticly, but I don't know that much about color
math. There is a method to find the standard highlight color, which
is what should be used.

Hello,
I saw your message where you were writing a custom NSStatusItem.
I'm doing the same now too. If I may ask, you create your own NSView
for the NSStatusItem. How does one draw the menu with the blue
background and show the menu itself? It appears that creating an
NSView overrides both drawing /and/ behavior. I can't help but feel
that I'm missing something obvious.
Thanks,
Sanford
