Search menu in Mac

In Mac applications, the little search box can have a pull down menu (similar to a View's pull down menu). It can have recent searches, user contributed menu entries, a menu item for clearing the recent searches etc. Here is the search box of Tweetie (the twitter app that I use):

Eclipse by default offers the SWT.SEARCH style which will bring this search box instead of the default text box. But there is no option to add the menu. For today's SWT-Cocoa hack, I tried to enhance the Search box with the search menu and here is the result:

The code is so ugly that I can't post it in public yet. Will post it with refinements tomorrow.

Update: The implementation is available here.
