<DIV>Hi all, </DIV>
<DIV>I try to use a silder to control the parameter used to change other
object. I use vtkSliderRepresentation2D and vtkSliderWidget as
my implement,but I do not know how to set
the step length that the silder shows. We can set the
SetMinimumValue() and SetMaximumValue()
by tkSliderRepresentation2D,when I drag the
slider the value is
Within the range! However the step length when
dragged is
<P>unpredictable, and HOW to control the step length? I want the
step length to be one,as I want to show images one layer by one
layer throught the slider.</P>
<P>Thanks a lot!</P>
