QTest::keyPress is not returning nativeScanCode

Hi,

I am simulating F1 key using QTest::keyPress() method to test keypress event, on simulation of F1 key when i check for nativeScanCode, it returns 0 value. can any one help?

Code:

---

//To simulate F1 key press
QTest::keyPress(&kboard, Qt::Key_F1);
 
//To check keypress Event
 void keyboard::keyPressEvent(QKeyEvent* ke) {
if ( ke->type() == QEvent::KeyPress ) {
 QKeyEvent* key_event = static_cast<QKeyEvent *>(ke);
 //To check F1 key simulation
 if (key_event->key() == Qt::Key_F1) {
    	int nativeCode = key_event->nativeScanCode();
    	qDebug()<< nativeCode <<endl;
	}
   }
 }

---

You are using artificial events so there is no extended information available for it.

Hi,

what is an extended information, is nativeScancode an extended info? plz throw some light on it.

Thanks

If you don't know what nativeScancode is, why do you use it?

I pretty well know nativeScancode is a unique unsigned int value which is returned on occurrence of a key stroke; from your POV artificial events (QTest::keyPress) don’t give extended information, want to know is nativeScancode one such extended information?

Would I write my post like that if it weren't? I assumed you have read the documentation prior to writing your post, maybe I assumed wrong, so - yes, according to what the docs say, native scan code is an extended information provided by the platform. Are you sure you do need this kind of information?

yep, I will ignore nativeScanCode and make use of QKeyEvent::key() which returns unicode

QKeyEvent::key() doesn't return unicode. It returns enum values.
