autorepeat and the alt key

[indigox3]

Hello,
I've installed an event filter in my app, and I'm trying to catch key events.

my code looks like this:

bool MyClass::eventFilter( QObject* pWindow, QEvent* pEvent ) 
{
	if( dynamic_cast<QKeyEvent*>(pEvent) )
	{
		OutputDebugString( L"key\n" );
	}
}

bool MyClass::eventFilter( QObject* pWindow, QEvent* pEvent ) 
{
	if( dynamic_cast<QKeyEvent*>(pEvent) )
	{
		OutputDebugString( L"key\n" );
	}
}

To copy to clipboard, switch view to plain text mode 

When I hold down a key, I get several events. They stop when I release the key. That is what I want, so that's good.

However when I hold down the alt key, I don't get multiple events when holding down the key. I only get one or two QKeyEvents.

Does anyone know why?

alt key is considered as key modifier in Qt, so I guess this is reason for only two events, you can check for alt key down(Qt::AltModifier) flag in QKeyEvent::modifiers () ;
