Description

The class of tool bars. A tool bar is a gadget that contains, as children, a number of buttons that give the user quick access to the more common commands in an application. Typically, the label for each button is an icon that pictorially represents the operation that clicking the button performs.

Figure 8.43 A tool bar

A tool bar is often placed underneath the menu bar of an application, although its position is very often configurable, and a tool bar may often be "docked" against any edge of the application's frame. In addition, a tool bar can sometimes be displayed as a free-floating window inside the application.

Internally, this class maps into the Windows toolbar control.
