wince6.0 Qt4.7 Keyboard key error

[SGaist]

What kind of keyboard is that exactly ?
Are you using any special locale ?

[CraigTao]

I come from China,
use English keyboard.
I think not use any special locale.

just the key "s" has problem, All other keys are normal.

[CraigTao]

Let me summarize the problem:
1 wince system virtual keyboard no problem;
2 physical keyboard is normal when use in wince system
For example, I create a folder and then change the name of the folder,
3 The s key has the same function as BackSpace key
4 If I press and hold the s button, can enter the s character normally

only The s key has this problem

[jsulm]

@CraigTao Is the keyboard maybe broken?
Did you configure the correct keyboard layout?

[CraigTao]

I replaced keyboard, the problem still exists.

I don't configure keyboard layout. only the s key.

and

"2 physical keyboard is normal when use in wince system
For example, I create a folder and then change the name of the folder,"

so. I think maybe Qt internal problem?

which part of Qt source code is handle system key message?

[SGaist]

As I already suggested, first test with Qt 4.8.7.

[CraigTao]

When I debugged, I found something interesting

Inherit from class QLineEdit to implement a LineEdit

void LineEdit::keyPressEvent( QKeyEvent* pEvent )
{
int val = pEvent->key();
QString = pEvent->text();
QLineEdit::keyPressEvent(pEvent);
}

key s character is ‘s' , but the key value is same as BackSpace : 16777219

[SGaist]

What locale are you using ?
And again, please test against the latest version of the Qt 4 series.

[CraigTao]

@SGaist thank you so much.
I can't update Qt version to 4.8.

Now use a method to solve this problem.

bool VirtualRunQt::eventFilter( QObject* pObject, QEvent* pEvent )
{
	if (pEvent->type() == QEvent::KeyPress) {
		QKeyEvent *ke = static_cast<QKeyEvent*>(pEvent);
		if (ke->text() == "s" && ke->key() == 16777219) {
			QKeyEventHelp* pKey = reinterpret_cast<QKeyEventHelp*>(ke);
			pKey->k = 83;
		}
	}
	return QObject::eventFilter(pObject, pEvent);
}

qApp->installEventFilter(this);

but I still think this is a bug in Qt4.73

@CraigTao said in wince6.0 Qt4.7 Keyboard key error:

I can't update Qt version to 4.8

It's just to test whether it is an issue with older Qt version you're using.

[CraigTao]

I will test when I am free, now so busy.

How do I set the post to be resolved?
