touchEvent register on a single widget on a multitouch screen

[tihoulas]

Hi,

I am currently trying to create a multitouch onscreen keyboard.
I own an asus t91mt, which has a dualtouch touchscreen.
My problem is that, although a TouchEvent can registers up to 2 touches, two different widgets cannot be touched at the same time.

It seems that once a widget recieves a TouchEvent, other widgets cannot, so that the second finger touch can only be recieved by the first widget touched.

All my widgets have the Qt::WA_AcceptTouchEvents property set.

Does anybody knows a way to bypass that issue ?

I would really like some help here, as I have been banging my head on the walls trying to figure that out.

Thanks in advance.

A quick update :
I have finally found that using setAttribute(Qt::AA_DontCreateNativeWidgetsSibblin gs) on my app allows it to function properly. But only with the first multi touch event. I cant press two buttons simultaneously, but only once. Any further atempt will miserably fail.

Is this a bug , or I have missed yet another thing ?

I am also facing exactly same issue.
The fingerpaint example works fine but the Multitouch Dial example doesn't work. I am using Qt 4.6.2 and Qt Creator 1.3
Does anyone know how to solve the issue?

Update:

Currently I am trying that two buttons receive touch event at the same time. But only one button receives the event.

Now if I place the buttons on a QFrame, they receive multitouch event but only for the first time, after that only one button receives touch event.
Here behavior is similar to post#2 by tihoulas.

I don't know what different happens when I place the buttons on QFrame. Any pointers would be helpful. Can some one point me to Nokia/Qt guys who might know about it?

Thanks
