mouse buttons

[wmjenkinson]

I've noticed that button presses are only detected when the x or y axis change. Is there away to correct this?

This is not the case here. I added a log output for the parameters of the MouseEventHandler() to sample/10-usbmouse and it shows:

Event 1 is "button pressed" and event 2 "button released". This is shown for the left and right button without the x/y position changing.

Maybe the behavior depends on the used USB mouse device.

I'll have a look at it and get back to you.

Got it! Thanks.
