For circular touchpads. +The LeftEdge, RightEdge, TopEdge and BottomEdge parameters are used to +define the edge and corner areas of the touchpad. The parameters split +the touchpad area in 9 pieces, like this: + + LeftEdge RightEdge + v v + | | Physical top edge + 1 | 2 | 3 + ------------------- TopEdge + | | + 4 | 5 | 6 + | | + ------------------- BottomEdge + 7 | 8 | 9 + | | Physical bottom edge + ^ ^ + Physical Physical + left edge right edge + +Coordinates to the left of LeftEdge are part of the left edge (areas +1, 4 and 7), coordinates to the left of LeftEdge and above TopEdge +(area 1) are part of the upper left corner, etc. A good way to find +appropriate edge parameters is to enable the SHMConfig option and run +"synclient -m 1" to see the x/y coordinates corresponding to different +positions on the touchpad. + A tap event happens when the finger is touched and released in a time interval shorter than MaxTapTime, and the touch and release coordinates are less than MaxTapMove units apart.
