Name:	clickTime
Class:	ClickTime
Command-Line Switch:	-clicktime
Interval time, in msec, used to determine that a single mouse click has occurred. Used to post menu on a "quick" mouse click. Note: changing this value may cause the sigle-click functionality to not work properly. The default is 150 msec.

Name:	command
Class:	Command
Command-Line Switch:	-command
Specifies a Tcl command procedure to be evaluated following a change in the current option menu selection.

Name:	cyclicOn
Class:	CyclicOn
Command-Line Switch:	-cyclicon
Turns on/off the 3rd mouse button capability. The value may be specified in any of the forms acceptable to Tcl_GetBoolean. This feature allows the right mouse button to cycle through the popup menu list without poping it up. The right mouse button cycles through the menu in reverse order. The default is true.

Name:	popupCursor
Class:	Cursor
Command-Line Switch:	-popupcursor
Specifies the mouse cursor to be used for the popup menu. The value may have any of the forms acceptable to Tk_GetCursor.

Name:	state
Class:	State
Command-Line Switch:	-state
Specified one of two states for the optionmenu: normal, or disabled. If the optionmenu is disabled, then option menu selection is ignored.

Name:	width
Class:	Width
Command-Line Switch:	-width
Specifies a fixed size for the menu button label in any of the forms acceptable to Tk_GetPixels. If the text is too small to fit in the label, the text is clipped. Note: Normally, when a new list is created, or new items are added to an existing list, the menu button label is resized automatically. Setting this option overrides that functionality.


The optionmenu command creates an option menu widget with options to manage it. An option menu displays a frame containing a label and a button. A pop-up menu will allow for the value of the button to change.


The optionmenu command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form: pathName option ?arg arg ...? Option and the args determine the exact behavior of the command.

Many of the widget commands for an optionmenu take as one argument an indicator of which entry of the option menu to operate on. These indicators are called indexes and may be specified in any of the following forms:

Specifies the entry numerically, where 0 corresponds to the top-most entry of the option menu, 1 to the entry below it, and so on.
Indicates the bottommost entry in the menu. If there are no entries in the menu then zero is returned.
Returns the numerical index of the currently selected option menu entry. If no entries exist in the menu, then -1 is returned.
If the index doesn't satisfy one of the above forms then this form is used. Pattern is pattern-matched against the label of each entry in the option menu, in order from the top down, until a matching entry is found. The rules of Tcl_StringMatch are used.

The following widget commands are possible for optionmenu widgets:


pathName cget option
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the optionmenu command.
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option-value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the optionmenu command.
pathName delete first ?last?
Delete all of the option menu entries between first and last inclusive. If last is omitted then it defaults to first.
pathName disable index
Disable the option menu entry specified by index. Disabling a menu item will prevent the user from being able to select this item from the menu. This only effects the state of the item in the menu, in other words, should the item be the currently selected item, the programmer is responsible for determining this condition and taking appropriate action.
pathName enable index
Enable the option menu entry specified by index. Enabling a menu item allows the user to select this item from the menu.
pathName get ?first? ?last?
If no arguments are specified, this operation returns the currently selected option menu item. Otherwise, it returns the name of the option at index first, or a range of options between first and last.
pathName index index
Returns the numerical index corresponding to index.
pathName insert index string ?string?
Insert an item, or list of items, into the menu at location index.
pathName select index
Select an item from the option menu to be displayed as the currently selected item.
pathName sort mode
Sort the current menu in either ascending, or descending order. The values increasing, or decreasing are also accepted.


Name:	menuBtn
Class:	Menubutton
The menuBtn component is the option menu button which displays the current choice from the popup menu. See the "menubutton" widget manual entry for details on the menuBtn component item.

Name:	popupMenu
Class:	Menu
The popupMenu component is menu displayed upon selection of the menu button. The menu contains the choices for the option menu. See the "menu" widget manual entry for details on the popupMenu component item.

Borrowed some ideas (next & previous) from OptionButton class.
