[Buildroot] About Buildroot+Qt+Qemu

[lee choon gay]

Hi.
I finally found a solution.
It is Qemu issue (my mistake in fact).
To execute Qemu to run Qt example, the command below is needed - add the "-usbdevice tablet".

qemu-system-i386 -kernel /path/to/kernel/bzImage -initrd /path/to/filesystem/rootfs.cpio -usbdevice tablet

Thanks.

 Hi.
 I am beginner for the tools stated above.
 I am currently using Buildroot 2014.05, Released May 31st,
 2014 to build kernel linux-3.14.4 with qt-4.8.6 for arch
 i386/variant i686.
 Then execute the bzImage using Qemu.
 Inside Qemu, I execute ./sliders -qws, I can see the GUI
 perfectly and able to type using keyboard.
 The problem is I cannot control the mouse (even the mouse
 pointer seems moving - pointer appear at coordinate 0,0 and
 disappear at other coordinates).
 I can't do anything with the mouse, can't click widget.
 
 I am running out of idea. I tried with vnc, directfb and
 etc, but still can't solve the problem, other problems show
 up. 
 Any body can help me on this?
 
 Thank you very much.
