DESCRIPTION
MessageDlg provides a simple way to display a message dialog.
MessageDlg::create creates the message dialog, displays it
and return the index of the pressed button, or -1 if it is
destroyed. When returning, the dialog no longer exists.
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 isn't
specified. Defaults to 150.
- -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.
- -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 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, and can be modified to set it in another
language by specifying the resource:
*MessageDlg.nameTitle: value
or the equivalent tcl command:
option add *MessageDlg.nameTitle value
where name is the name of an icon as defined in the
icon option.
For example, for french language, you can specify for a warning
dialog:
option add *MessageDlg.warningTitle "Attention"
