How to set data

[sonuani]

hi,
Actually i have a QLineedit in designer which has 0 initially.When i want to enter data into the QLineedit then this 0 has to be cleared and i should be able to enter data.
I am able to do it manually.But when i click that control then immediately,it should be cleared off.
Thanks

You can install an event filter to intercept the QFocusEvent and clear the QLineEdit (be sure to check the focus reason).

See: QObject::installEventFilter()
