NAME

MessageDlg - a message dialog box

SYNOPSIS

MessageDlg pathName ?option value...?

DESCRIPTION

The command MessageDlg creates the message dialog, displays it and returns the index of the pressed button. If the dialog is closed without a button press, the value returned is that of the -cancel option, or -1 if that option has not been set. Upon return the dialog has been destroyed.

WIDGET-SPECIFIC OPTIONS

-aspect
Specifies a non-negative integer value indicating desired aspect ratio for the text. The aspect ratio is specified as 100*width/height. 100 means the text should be as wide as it is tall, 200 means the text should be twice as wide as it is tall, 50 means the text should be twice as tall as it is wide, and so on. Used to choose line length for text if -width option is not specified. Defaults to 150. The options -width and -aspect are directly inherited from the Tk message widget.
-buttons
Specifies a list of buttons to display when type option is user. If a button has a symbolic name, its associated text will be displayed.
-buttonwidth
Specifies the standard width of the buttons in the dialog.
-icon
Specifies an icon to display. Must be one of the following: error, info, question or warning.
-justify
Specifies how to justify lines of text. Must be one of left, center, or right. Defaults to left. This option works together with the anchor, aspect, padx, pady, and width options to provide a variety of arrangements of the text within the window. The aspect and width options determine the amount of screen space needed to display the text. The anchor, padx, and pady options determine where this rectangular area is displayed within the widget's window, and the justify option determines how each line is displayed within that rectangular region. For example, suppose anchor is e and justify is left, and that the message window is much larger than needed for the text. The the text will displayed so that the left edges of all the lines line up and the right edge of the longest line is padx from the right side of the window; the entire text block will be centered in the vertical span of the window.
-message
Specifies the message to display in this message box.
-title
Specifies a string string to display as the title of the message box. If the value is empty (the default), a default title will be set corresponding to the -icon option. The default associated title is in English. To use another language, examine the module Slab::lang::code where code identifies the Tcl msgcat locale, and ensure that the key stringTitle in the namespace ::Slab::MessageDlg has the required value. For example, the module Slab::lang::de for German includes the code:
namespace eval ::Slab {
    namespace eval MessageDlg {
        ::msgcat::mcset de noneTitle       Meldung
        ::msgcat::mcset de infoTitle       Hinweis
        ::msgcat::mcset de questionTitle   Frage
        ::msgcat::mcset de warningTitle    Warnung
        ::msgcat::mcset de errorTitle      Fehler
    }
}
-type
Specifies a set of buttons to be displayed. The following values are possible:

abortretryignore
Displays three buttons whose symbolic names are abort, retry and ignore.

ok
Displays one button whose symbolic name is ok.

okcancel
Displays two buttons whose symbolic names are ok and cancel.

retrycancel
Displays two buttons whose symbolic names are retry and cancel.

yesno
Displays two buttons whose symbolic names are yes and no.

yesnocancel
Displays three buttons whose symbolic names are yes, no and cancel.

user
Displays buttons of -buttons option.

For any -type but user, the native Tk widget tk_messageBox is used, and only the following options are considered: -default, -icon, -message, -title and -type.
-width
Specifies the length of lines in the window. If this option has a value greater than zero then the aspect option is ignored and the width option determines the line length. If this option has a value less than or equal to zero, then the aspect option determines the line length.
