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'].

Keyword	Definition	Value
value	Initial value of the slider	Default is 0
range	The (min, max) range of the slider	Default is (0, 1)
pageSize	The amount to jump the slider when the user clicks left or right of the thumb	Default is 0.1
orientation	The orientation of the slider	HORIZONTAL or VERTICAL
command	Function called when the value of the slider changes (takes no arguments)	Function
extraArgs	Extra arguments to the function specified in command	[Extra Arguments]
thumb_geom, thumb_relief, thumb_text, thumb_frameSize, etc.	Parameters to control the look of the thumb	Any parameters appropriate to DirectButton

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
