# DirectSlider¶

Use a DirectSlider to make a slider, a widget that allows the user to select a value between a bounded interval.

A DirectSlider consists of a long bar, by default horizontal, along with a “thumb”, which is a special button that the user may move left or right along the bar. The normal DirectGui parameters such as frameSize, geom, and relief control the look of the bar; to control the look of the thumb, prefix each of these parameters with the prefix “thumb_”, e.g. thumb_frameSize.

If you want to get (or modify) the current value of the slider (by default, the range is between 0 and 1), use mySlider['value'].

## Example¶

import direct.directbase.DirectStart
from direct.gui.DirectGui import *

def showValue():
print(slider['value'])

slider = DirectSlider(range=(0,100), value=50, pageSize=3, command=showValue)

base.run()


“range” sets values between 0 and 100 “value” sets initial value to 50 “pageSize” sets the step between mouseclicks to 3 (approximately) “command” calls the showValue-function implemented above
