change widget slider maximum dynamically? [message #17594]

Hi,

No doubt someone has probably figured this one out some time ago.
However can anyone help me with using the widget slider control? In
particular I would like to be able to set the maximum value of the
widget slider dynamically (i.e. after the slider has been realized). I
would like to set the maximum value of the slider at the conclusion of
reading in a data set. Since a new data set may contain a different
number of "groups" then the first one then it would be ideal to simply
update the maximum in the slider.

Thanks in advance!

Rob

I've been using these two keywords for a long time to control the
current visible range of plotted points on graphs. When the limits for
the subplot are changed, the min/max values must be changed
accordingly for the sliders.

BTW, I've used the Floating Point Slider and find it very cludgey and
awkward (only updates upon an upclick). Would be nice to have RSI
*write their own* in ANSI C and bring it up to the standards of the
other widgets. Last I checked, the FP Slider is just a combination of a
slider and a text widget.
