Everyday Software has released Mac OS X Toolbar Buttons Pro, which lets you create Cocoa-like toolbars found in various Mac OS X apps.
Cocoa is an advanced object-oriented programming environment. According to Apple, Cocoa gives developers a whole new toolbox for building the best next-generation applications. It’s a collection of advanced, object-oriented APIs for developing applications written in Java and Objective-C.
The pro version of Toolbar Buttons includes a toolbar view controller to facilitate implementation, contextual menu support, window resizing support, separator lines, drawing optimizations, full Appearance Manager support and a modified appearance under the Classic Mac operating system. Mac OS X Toolbar Buttons Pro also has support for button submenus and three views (icon & text, icon only, and text only).
The cost is US$30 for an unlimited distribution of the button classes and Everyday Software’s Carbon Events plug-in that adds a toolbar button (and more) under Mac OS X. Or $25 will get you an unlimited distribution of the button classes only. More info and a demo can be found at the product Web site.
