key Press which key

[caduel]

how about having a look at designer (its sources, rather)? one of the benefits of open source...

[Lykurg]

Please verify for me: Key press, insert "+", short cut??? Don't understand...

[aekilic]

I was not able to find it on the designer codes

[Lykurg]

Since neither you nor my crystal ball explains the question to my I just talk in the wind: Subclass QLineEdit use the key press event filter and check for QKeySequence or any other shortcut and emit a signal or call a function. Or use textChanged ( const QString & text ) and check if there is a + and then do what ever you want.

[aekilic]

Is there any example that could help me?

I would like to chacht which key hes been presses on a qlineedit and write it to the line itself.

[aekilic]

any body can help me for thiss???

install event filter on your line edit and process QKeyEvent.

[Lykurg]

or subclass QLineEdit and then:

void YourLineEdit::keyPressEvent(QKeyEvent *e)
{
  if (Qt::Key_Plus == e->key())
    qDebug("+ was pressed I ignore that")
  else
    QLineEdit::keyPressEvent(e);
}

void YourLineEdit::keyPressEvent(QKeyEvent *e)
{
  if (Qt::Key_Plus == e->key())
    qDebug("+ was pressed I ignore that")
  else
    QLineEdit::keyPressEvent(e);
}
