Question about GamepadTouch Interface

[于洋]

Hello~

I saw there's new added GamepadTouch Interface, related patch:

https://chromium-review.googlesource.com/c/chromium/src/+/3866373

does this API only supported in Windows platform and dualshock4 gamepad only?

I tried to test this API using these 2 samples:

https://github.com/luser/gamepadtest

https://github.com/bradleyneedham/gamepadtest

my test platform is arm architecture and Linux type OS, with chromium M120 version.

target device is dualshock4.

I pressed buttons and joystick and touch the TouchPad(is this the correct way to invoke GamepadTouch event?)

All buttons and axes works fine, but controller.touchEvents is always null.

I also tried to test in my PC of win10, with chrome version:

版本 125.0.6422.142（正式版本） （64 位）

but the result is same.

Could you help to fingure out the possible reason please?

Thank you very much~
