Keyboard event and QTextEdit

[kaszewczyk]

Hello,
i have problem with handling keyboard event, the problem is related to QTextEdit Widget the point is:
i have QTextEdit object for example called writeTextEdit and i installed on it event filter

this->writeTextEdit->installEventFilter(this);

this->writeTextEdit->installEventFilter(this);

To copy to clipboard, switch view to plain text mode 

next i implement eventFilter method

bool FooClass::eventFilter(QObject* _o, QEvent* _e){
    if(_e->type() == QEvent::KeyPress){
        QKeyEvent* eventKey = static_cast<QKeyEvent*>(_e);
        if(eventKey->key() == Qt::Key_Return){
            //do something
        }
        return true;
    }else{
        return QObject::eventFilter(_o, _e);
    }
}

bool FooClass::eventFilter(QObject* _o, QEvent* _e){
    if(_e->type() == QEvent::KeyPress){
        QKeyEvent* eventKey = static_cast<QKeyEvent*>(_e);
        if(eventKey->key() == Qt::Key_Return){
            //do something
        }
        return true;
    }else{
        return QObject::eventFilter(_o, _e);
    }
}

To copy to clipboard, switch view to plain text mode 

and when i run my app and want to write something in QTextEdit no letters are show inside, what is the problem?

For what i see in your code for every key is pressed you check if the key is return then do something. if you are not pressing the return key you simply return true you should return the BaseClass eventFilter (thinking that FooClass extends QTextEdit).

Well maybe something like that:

bool FooClass::eventFilter(QObject* _o, QEvent* _e)
{
   if(_e->type() == QEvent::KeyPress)
   {
      QKeyEvent* eventKey = static_cast<QKeyEvent*>(_e);
      if(eventKey->key() == Qt::Key_Return)
      {
         //do something
         return true;
      }
   }
   return QTextEdit::eventFilter(_o, _e);
}

bool FooClass::eventFilter(QObject* _o, QEvent* _e)
{
   if(_e->type() == QEvent::KeyPress)
   {
      QKeyEvent* eventKey = static_cast<QKeyEvent*>(_e);
      if(eventKey->key() == Qt::Key_Return)
      {
         //do something
         return true;
      }
   }
   return QTextEdit::eventFilter(_o, _e);
}
