A General/TagCloud is a way of displaying a set of terms that allows for perusal alphabetically and by frequency. See http://en.wikipedia.org/wiki/Tag_cloud.

A Cocoa implementation is available at http://www.fernlightning.com/doku.php?id=randd:tcloud:start.

—-From Jerry Krinock: This is very cool. I have several enhancements to this project:

• if enclosed in scroll view, scrolls to show all tags.
• if no scroll view, only shows tags that fully fit in the view
• extend/multiple selection by shift-clicking or cmd-clicking
• selections remain highlighted until deselected
• added setEnabled:(BOOL)yn (no = cannot select items)
• added a KVO-compliant read-only getter for “selected tags”
• argument to -setTags: (formerly setStats:, I believe) may now be General/NSSet, as well as an General/NSArray, and it may contain simple General/NSString objects as well ofCountedTag objects. In the latter case, all tags are drawn with same size. The argument to -setTags may also be nil, in which case the layout will be skipped, and view will be empty
• fixed memory leak (General/NSScanner, scan)
• Re-cast as an General/NSControl which sends an action on leftMouseDown
• Instead of setStyle:, there are two setters: -setShowsReflections:(BOOL)yn _setBackgroundWhiteness:(float)whiteness (The black is a little too extreme for a non-game app ;)
• Becomes first responder and responds to selectAll: by selecting all tags (not working yet)
• Demo app shows most of the new features, such as a tableView bound to selectedTags

I will make it available when done testing, or let me know if you want it “as is”. jerry@ieee.org —-
