Hello
I noticed a bug in paraview on parsing double values in QLineEdits, e.g. in
pqDoubleEdit:
double pqDoubleEdit::value()
{
QString currentText = this->text();
int currentPos = this->cursorPosition();
QDoubleValidator dvalidator(NULL);
QValidator::State state = dvalidator.validate(currentText, currentPos);
if (state == QValidator::Acceptable || state == QValidator::Intermediate)
{
return currentText.toDouble();
}
return 0.0;
}
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
http://doc.qt.io/qt-5/qstring.html#toDouble , here the
http://doc.qt.io/qt-5/qlocale.html#toDouble is recommended.... So all QLineEdit
functions with toDouble must be replaced by
QLocale oL;
Double dValue = oL.toDouble( lineEdit->text())
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)...
Best regards
