NAME
tk_messageBox - pops up a message window and waits for user response.
SYNOPSIS
tk_messageBox ?option value ...?
DESCRIPTION
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:
- -command string
- Specifies the prefix of a Tcl command to invoke when the user closes the dialog. The actual command consists of string followed by a space and the name of the button clicked by the user to close the dialog. This is only available on macOS.
- -default name
- 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 this option is not specified, the first button in the dialog will be made the default.
- -detail string
- Specifies an auxiliary message to the main message given by the -message option. The message detail will be presented beneath the main message and, where supported by the OS, in a less emphasized font than the main message.
- -icon iconImage
- Specifies an icon to display. IconImage must be one of the following: error, info, question or warning. If this option is not specified, then the info icon will be displayed.
- -message string
- Specifies the message to display in this message box. The default value is an empty string.
- -parent window
- Makes window the logical parent of the message box. The message box is displayed on top of its parent window.
- -title titleString
- Specifies a string to display as the title of the message box. The default value is an empty string.
