Don't mind the mess!

We're currently in the process of migrating the Panda3D Manual to a new service. This is a temporary layout in the meantime.

Use a DirectSlider to make a slider, a widget that allows the user to select a value between a bounded interval. DirectSlider is available beginning in Panda3D 1.1.

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


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)

"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
