Hi,

Does anyone know if it's possible to force an NSComboBox to show its list programmatically, i.e. not waiting for the user to click the arrow button or press the down arrow key? I basically want it to behave like the URL field in web browsers.

I cannot find any method that looks like it will to that. Will I need to use a custom control for this?

Thanks
Amar

I've tried to do this before as well. There seems to be no public method. I had a look at the class-dumped AppKit headers and found private methods that could be called but for me that's rather unsatisfactory. Take a look at

which may do what you want.

Brilliant, thanks! That works rather well.

One thing, though: Is it possible to make the drop-down list follow the window continuously as it's being moved around?
I've tried updating its position from within the windowDidMove method, but that only seems to get called after the mouse rests.

Thanks
Amar

It'd probably be easier and safer to just implement your own drop-down: that's the way our URL-field and form autocomplete works in OmniWeb, and it looks like Safari's work that way as well.

Just create a borderless window with an NSTableView in it, and position/show it when the user starts typing. To make it follow the parent window around, use the new NSWindow parent/child APIs introduced in 10.3.
