Menu Attributes

A menu has a few global attributes, and then each menu entry has many button-like attributes that describe its appearance and behavior. Table 27-5 specifies the attributes that apply globally to the menu, unless overridden by a per-entry attribute. The table uses the X resource names, which may have a capital at interior word boundaries. In Tcl commands, use all lowercase and a leading dash.

Table 27-5. Menu attribute resource names.

activeBackground	Background color when the mouse is over a menu entry.
activeForeground	Text color when the mouse is over a menu entry.
activeBorderWidth	Width of the raised border around active entries.

borderWidth	Width of the border around all the menu entries.
cursor	Cursor to display when mouse is over the menu.
disabledForeground	Foreground (text) color when menu entries are disabled.

postCommand	Tcl command to run just before the menu is posted.
selectColor	Color for selector in check and radio type entries.
takeFocus	Control focus changes from keyboard traversal.
tearOff	True if menu should contain a tear-off entry.
tearOffCommand	Command to execute when menu is torn off. Two arguments are added: the original menu and the new tear-off.
type	(Read-only) normal, menubar, or tearoff. (Tk 8.0).

Table 27-6 describes the attributes for menu entries, as you would use them in a Tcl command (i.e., all lowercase with a leading dash.) The attributes for menu entries are not supported directly by the resource database. However, Example 28-6 on page 411 describes how you can use the resource database for menu entries.
