Did you do qt4 (qws)+directfb on imx6?

Yes, I used a Q Windowing System.

However, I have obtained specific "mkspecs" for i.MX5X micro.

I had built Qt4.8.2(qws) on imx6 with directfb display, and it is worked.

But I have two problems:

1. The DirectFB display plugin is some time crushed.

2. I need to support multitouch with QT, but Q Windowing System seems like not support Qtouch event(Qmouse only),

Do you have any ideas with this?

Thank you!

Hi,

Thank you very much.

I have done the multi-touch works on Qt4.8.2(qws) system.

The next problem is the directfb plugin.

Have you done this before?
