How could I make the QLineEdit UpperCase without using InputMask?

[spirit]

a little bit tricky, but works fine

...
connect(le, SIGNAL(textEdited(const QString &)), SLOT(toUpper(const QString &)));
...
void Test::toUpper(const QString &text)
{
	QLineEdit *le = qobject_cast<QLineEdit *>(sender());
	if (!le)
		return;
	le->setText(text.toUpper());
}

...
connect(le, SIGNAL(textEdited(const QString &)), SLOT(toUpper(const QString &)));
...
void Test::toUpper(const QString &text)
{
	QLineEdit *le = qobject_cast<QLineEdit *>(sender());
	if (!le)
		return;
	le->setText(text.toUpper());
}

To copy to clipboard, switch view to plain text mode
