<div>Hello</div>
<div> </div>
<div>I noticed a bug in paraview on parsing double values in QLineEdits, e.g. in pqDoubleEdit:</div>
<div> </div>
<div>double pqDoubleEdit::value()</div>
<div>{</div>
<div> QString currentText = this->text();</div>
<div> int currentPos = this->cursorPosition();</div>
<div> QDoubleValidator dvalidator(NULL);</div>
<div> QValidator::State state = dvalidator.validate(currentText, currentPos);</div>
<div> if (state == QValidator::Acceptable || state == QValidator::Intermediate)</div>
<div> {</div>
<div> return currentText.toDouble();</div>
<div> }</div>
<div> return 0.0;</div>
<div>}</div>
<div> </div>
<div>The Problem is that QDoubleValidator uses the current locale. If the current locale is e.g. German that e.g. “0.1” is not allowed, only “0,1”. On the other side the QString function toDouble cannot parse it correctly, see documentation <a href="http://doc.qt.io/qt-5/qstring.html#toDouble"><font color="blue"><u>http://doc.qt.io/qt-5/qstring.html#toDouble</u></font></a>
, here the <a href="http://doc.qt.io/qt-5/qlocale.html#toDouble"><font color="blue"><u>http://doc.qt.io/qt-5/qlocale.html#toDouble</u></font></a> is recommended…. So all QLineEdit functions with toDouble must be replaced by </div>
<div>QLocale oL;</div>
<div>Double dValue = oL.toDouble( lineEdit->text())</div>
<div> </div>
<div>Nasty….Other solution would be to set the locale to English for whole paraview regardless to the system locale, but I don’t know if that is possible (also not very beautiful)…</div>
<div> </div>
<div>Best regards</div>
