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 \fB\-width\fR option -is not specified. -Defaults to 150. -.OP \-justify justify Justify -Specifies how to justify lines of text. -Must be one of \fBleft\fR, \fBcenter\fR, or \fBright\fR. Defaults -to \fBleft\fR. -This option works together with the \fB\-anchor\fR, \fB\-aspect\fR, -\fB\-padx\fR, \fB\-pady\fR, and \fB\-width\fR options to provide a variety -of arrangements of the text within the window. -The \fB\-aspect\fR and \fB\-width\fR options determine the amount of -screen space needed to display the text. -The \fB\-anchor\fR, \fB\-padx\fR, and \fB\-pady\fR options determine where this -rectangular area is displayed within the widget's window, and the -\fB\-justify\fR option determines how each line is displayed within that -rectangular region. -For example, suppose \fB\-anchor\fR is \fBe\fR and \fB\-justify\fR is -\fBleft\fR, and that the message window is much larger than needed -for the text. -The text will be displayed so that the left edges of all the lines -line up and the right edge of the longest line is \fB\-padx\fR from -the right side of the window; the entire text block will be centered -in the vertical span of the window. -.OP \-width width Width -Specifies the length of lines in the window. -The value may have any of the forms acceptable to \fBTk_GetPixels\fR. -If this option has a value greater than zero then the \fB\-aspect\fR -option is ignored and the \fB\-width\fR option determines the line -length. -If this option has a value less than or equal to zero, then -the \fB\-aspect\fR option determines the line length. -.BE -.SH DESCRIPTION -.PP -The \fBmessage\fR command creates a new window (given by the -\fIpathName\fR argument) and makes it into a message widget. -Additional -options, described above, may be specified on the command line -or in the option database -to configure aspects of the message such as its colors, font, -text, and initial relief. The \fBmessage\fR command returns its -\fIpathName\fR argument. At the time this command is invoked, -there must not exist a window named \fIpathName\fR, but -\fIpathName\fR's parent must exist. -.PP -A message is a widget that displays a textual string. A message -widget has three special features that differentiate it from a -\fBlabel\fR widget. First, it breaks up -its string into lines in order to produce a given aspect ratio -for the window. The line breaks are chosen at word boundaries -wherever possible (if not even a single word would fit on a -line, then the word will be split across lines). Newline characters -in the string will force line breaks; they can be used, for example, -to leave blank lines in the display. -.PP -The second feature of a message widget is justification. The text -may be displayed left-justified (each line starts at the left side of -the window), centered on a line-by-line basis, or right-justified -(each line ends at the right side of the window). -.PP -The third feature of a message widget is that it handles control -characters and non-printing characters specially. Tab characters -are replaced with enough blank space to line up on the next -8-character boundary. Newlines cause line breaks. Other control -characters (ASCII code less than 0x20) and characters not defined -in the font are displayed as a four-character sequence \fB\ex\fIhh\fR where -\fIhh\fR is the two-digit hexadecimal number corresponding to -the character. In the unusual case where the font does not contain -all of the characters in -.QW 0123456789abcdef\ex -then control characters and undefined characters are not displayed at all. -.SH "WIDGET COMMAND" -.PP -The \fBmessage\fR command creates a new Tcl command whose -name is \fIpathName\fR. This -command may be used to invoke various -operations on the widget. It has the following general form: -.CS -\fIpathName option \fR?\fIarg arg ...\fR? -.CE -\fIOption\fR and the \fIarg\fRs -determine the exact behavior of the command. The following -commands are possible for message widgets: -.TP -\fIpathName \fBcget \fIoption\fR -. -Returns the current value of the configuration option given -by \fIoption\fR. -\fIOption\fR may have any of the values accepted by the \fBmessage\fR -command. -.TP -\fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? -. -Query or modify the configuration options of the widget. -If no \fIoption\fR is specified, returns a list describing all of -the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for -information on the format of this list). If \fIoption\fR is specified -with no \fIvalue\fR, 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 \fIoption\fR is specified). If -one or more \fIoption\-value\fR 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. -\fIOption\fR may have any of the values accepted by the \fBmessage\fR -command. -.SH "DEFAULT BINDINGS" -.PP -When a new message is created, it has no default event bindings: -messages are intended for output purposes only. -.SH BUGS -.PP -Tabs do not work very well with text that is centered or right-justified. -The most common result is that the line is justified wrong. -.SH "SEE ALSO" -label(n) -.SH KEYWORDS -message, widget -'\" Local Variables: -'\" mode: nroff -'\" End: |
