QLineEdit placeholder text not working in Qt 4.6.3

Question

I am using Qt 4.6.3, and tried to set some placeholder text on a QLineEdit. But these methods didn't work:

• using Qt designer (uic)
• through code ui->lineedit.setPlaceholderText("phtext")
• setProperty("placeholderText","phtext")

The error is that setPlaceholderText is not a member of the QLineEdit class.

Is this a bug and\or is there a way to fix it?

Answer 1

The placeholderText property was introduced in Qt 4.7 (see documentation), so it doesn't exist in Qt 4.6.
