# The first argument indicates the icon used: one of QtGui.QMessageBox.{NoIcon, Information, Warning, Critical, Question}

In order to use the accented characters in the text field from <b>Qt</b>, using the tag <b> #-*-coding: utf-8-*- </b> must be added a <b>u</b> before the message to display<br /> Example :
|
|
</p>
|
|
<pre>diag = QtGui.QMessageBox(QtGui.QMessageBox.Warning, u'Trop d'éléments désignés', msg)
|
|
...
|
|
...
|
|
msg = u'Élément sélectionnés affichés' </pre>
|
|
<p><br />
|
|
To display multiple lines in a dialog box <b>Qt</b>, must be added <b>"\n"</b> (quotation, valid also between apostrophes) between each line.<br />
|
|
Valid also <b> "\r\n"</b> which correspond to <b>CR</b> carriage return, and <b>LF</b> end of line, valid also <b>" \t"</b> is a tab, characters should be between quotation marks (and apostrophes) as a character string, the tags can be found next to the text to display <b>" \nRayon\t: "</b>, the tag <b>" \ "</b> (reversed slash) defines the command.<br />
|
|
Example :
|
|
</p>
|
|
<pre>diag = QtGui.QMessageBox(QtGui.QMessageBox.Information,u"Coordonnées",u"Coordonnée X : "+str(x)+"\r\n"+u"Coordonnée Y : "+str(y)+"\n"+u"Coordonnée Z :<br>
