Trackbar behavior

Hi,

I have one trackbar which has minimum=0 and maximum=100. I just want to allow user to move slider to positions 20, 40, 60 and 80. I set the min and max jump to 20 but this allows user to set value 0 and 100 too which I dont want to allow.

Is there any way I can achieve this?
