Hi,
If I understand correctly, you are trying to work with the patches I
submitted, nearly a year ago.
First, I would just say that the work concerning this branch of evdev is
not maintained as it has a lot of problems (limit of the maximum count
of contact, etc).
Multitouch will be available with XInput 2.1.
My first Idea was to create floating devices, but I encountered a bug I
did not have the time to patch. If the driver creates a floating device,
and you attach this device to a master one, I had trouble transferring
the events. That's why I did not created floating devices.
BTW, if want to give it a test, you can just uncomment the line:
EvdevReplaceOption(input_options, "SendCoreEvents","off");
before calling NewInputDeviceRequest.
Cheers,
Benjamin

Hi,
Is there any one who knows how to create floting device in Xorg input driver ?
I'm writing an Xorg multitouch driver based on
xf86-input-evdev-multitouch driver.
In the driver, sub devices for multiple fingers will be created using
NewInputDeviceReuqest()
and will be removed using DeleteInputDeviceRequest().
If a device property was set by multitouch daemon application, the sub
devices will be created newly and will be removed.
For example, commands for doing that are : # multitouchctl 3
If the sub devices are created, then multitouch daemon gets a
XI_HierarchyChanged event, and set them as floating slaves
using XIChangeHierarchy() function.
What I want to do is creating the sub devices as floating slaves in
evdev-multitouch driver.
Is there any one who knows how to create floting device in Xorg input driver ?
Thanks,
Sung-Jin Park
