How to show tooltip for a widget from code

[jarda]

Hello all,
I want to show tooltip for QLineEdit from a code as a hint for a user that there (in lineEdit) is something wrong.
But I cannot find how to do it. I want to ask if it is possible to show tooltip by the code?

Thank in advance,
Jarda

Try this:
@QToolTip::showText( widget->mapToGlobal( QPoint( 0, 0 ) ), errorString );@

Thanks very much p-himik. That is exactly what I needed.

I think that the correct way is using this:

@setToolTip( const QString & )@

like
@QString tooltip="Wrong text near: .."
lineEdt->setToolTip(tooltip)@

This will show toolTip only if you hold your mouse cursor on this widget for a while. Jarda wants to show it on demand from his code.

My bad, as the tittle say "how to show tooltip for a widget from code", but what jarda wants is to "trigger" the show tooltip..

Trigger as in "show", yes. Your code does not trigger nor show, it only sets.
