tk_messageBox - pops up a message window and waits for user response.
tk_messageBox ?option value ...?
This procedure creates and displays a message window with an application-specified message, an icon and a set of buttons. Each of the buttons in the message window is identified by a unique symbolic name (see the -type options). After the message window is popped up, tk_messageBox waits for the user to select one of the buttons. Then it returns the symbolic name of the selected button. The following option-value pairs are supported:
Name gives the symbolic name of the default button for this message window ('ok', 'cancel', and so on). See -type for a list of the symbolic names. If the message box has just one button it will automatically be made the default, otherwise if this option is not specified, there won't be any default button.
Specifies an icon to display. IconImage must be one of the following: error, info, question or warning. If this option is not specified, then no icon will be displayed.
Specifies the message to display in this message box.
Makes $widget the logical parent of the message box. The message box is displayed on top of its parent window.
Specifies a string to display as the title of the message box. The default value is an empty string.
Arranges for a predefined set of buttons to be displayed. The following values are possible for predefinedType:
Displays three buttons whose symbolic names are abort, retry and ignore.
Displays one button whose symbolic name is ok.
Displays two buttons whose symbolic names are ok and cancel.
Displays two buttons whose symbolic names are retry and cancel.
Displays two buttons whose symbolic names are yes and no.
Displays three buttons whose symbolic names are yes, no and cancel.
