Look for both left and right mouse click -Information provided by Jo Even Skarstein
To look for any mouse button when using EVNT_MULTI or EVNT_BUTTON you do like this:
- Set EV_MBCLICKS to 258
- Set EV_MBMASK to 3 (Look for bit 1 & bit 2)
This is how it works:
Bit 8 (equals 256) enables wait for both/either button
Thus you add 256 to the number of expected mouse clicks (Usually this is set to 2)
256+2 = 258
Action: Waits for one or more mouse clicks, and returns the number of clicks.
