I have some strange behaviour with DirectSlider. If I use ‘too small’ pageSize (0.01 or 0.001 …) it does not move the slider and does not give correct value.
import direct.directbase.DirectStart from direct.gui.DirectGui import * def showValue(): print slider['value'] slider = DirectSlider(range=(1,10), value=2, pageSize=.01, command=showValue) print 'scrollSize:%s' %slider['scrollSize'] run()
When clicking on the right or left side of the thumb it still reports 2, but not 2.01, 2.02.
Of course 2.01 is ideal case which I know will be actually something like 2.0987 - I’m not looking such precision.
I tried to make the range small too, so the pageSize actually could move the thumb, but it didn’t help.
I use Panda3D 1.7.2 on Ubuntu x64.
I thought it was some float precision problem, but could not find the source to test it. I guess the real work is made by PGItem which is C code, I think.
Is this a bug or it is not expected to work with small pageSizes ?
