A bit mask of the button (or buttons) required to recognize this gesture.
- macOS 10.10+
Bit 0 represents the primary button, bit 1 is the secondary button, and so on. So to track clicks of the secondary button, assign the value
0x2 (which corresponds to a
1 in bit 1) to this property. The default value of this property is 0x1, which detects clicks in the primary mouse button.
Changing the value of this property also sets the values of the
delays properties to
YES for each of the buttons you specified.
