|
||
|
|

|

|
||
|
|
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 <B>width</B> option
|
||
|
|
isn't specified.
|
||
|
|
Defaults to 150.

|
||
|
|
<B>question</B> or <B>warning</B>.

|
|
||
|
|
Specifies how to justify lines of text.
|
||
|
|
Must be one of <B>left</B>, <B>center</B>, or <B>right</B>. Defaults
|
||
|
|
to <B>left</B>.
|
||
|
|
This option works together with the <B>anchor</B>, <B>aspect</B>,
|
||
|
|
<B>padx</B>, <B>pady</B>, and <B>width</B> options to provide a variety
|
||
|
|
of arrangements of the text within the window.
|
||
|
|
The <B>aspect</B> and <B>width</B> options determine the amount of
|
||
|
|
screen space needed to display the text.
|
||
|
|
The <B>anchor</B>, <B>padx</B>, and <B>pady</B> options determine where this
|
||
|
|
rectangular area is displayed within the widget's window, and the
|
||
|
|
<B>justify</B> option determines how each line is displayed within that
|
||
|
|
rectangular region.
|
||
|
|
For example, suppose <B>anchor</B> is <B>e</B> and <B>justify</B> is
|
||
|
|
<B>left</B>, 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 <B>padx</B> from
|
||
|
|
the right side of the window; the entire text block will be centered
|
||
|
|
in the vertical span of the window.

|
||
|
|
The default associated title is in english, and can be modified to set it in
|
||
|
|
another language by specifying the resource:
|
||
|
|

|

|
|
or the equivalent tcl command:
|
||
|
|
<PRE> option add *MessageDlg.<I>name</I>Title <I>value</I></PRE>
|
||
|
|
where <I>name</I> is the name of an icon as defined in the <B>icon</B> option.
|
||
|
|
<BR>For example, for french language, you can specify for a warning dialog:
|
||
|
|
<PRE> option add *MessageDlg.warningTitle "Attention"</PRE>
