QRegExpValidator.h does not exist

[GGAZ]

Hello, I'm developping an application using Qt 6.4.0.
I have an error :
'QRegExpValidator' file not found.
In the Gui directory, indeed the file QRegExpValidator.h does not exist, is this normal?

@GGAZ Do you have

QT += gui

in your pro file?

If you're using Qt6 then use QRegularExpressionValidator instead.

@jsulm yes! I have done this QT += gui
with QRegularExpressionValidator it works better
Merci!
