I have not put those in yet.
Don't worry they will be in the next update as well as a DoubleClick option for each button type.
Also, and this may take some time, but I am making the library compatible with the Adafruit libraries like the Adafruit_ILI9341 and GFX libraries.
I am also finishing up the Gauge Class to have numbers in the center now that I finished my Scalefont library. The Arc around the gauge will move, so no more needle, but if enough people ask for it then I guess I will add it in.
Good things come to those who wait. 
Update as of 10/31/2015:
Meter class with Vertical and Horizontal orientations is done.
DoubleClick is done
Gauge class is done. (no needle)
Gauge class including ScaleFonts library is done.
Adafruit compatibility is not 100% done.
