Summary of the Tk Commands

The following tables list the Tcl commands added by Tk. Table 21-1 lists commands that create widgets. There are 15 different widgets in Tk, although 4 of them are variations on a button, and 5 are devoted to different flavors of text display. Table 21-2 lists commands that manipulate widgets and provide associated functions like input focus, event binding, and geometry management. Table 21-3 lists several support procedures that implement standard dialogs, option menus, and other facilities. The page number in the table is the primary reference for the command, and there are other references in the index.
