Hello,
I have two questions.

1. How can I create and assigned an LinearSpline to a SplineData ?
I like to build an linear sline as default spline in an own CUSTOMDATATYPE_SPLINE.

2. If I have an existing spline, I can set the ranges with "AdaptRange(...)". But the dialog or
the GUI doesn't updated. Only if I open the dialog in a separate window it's updated. Which
message or command do I need ?

thanks
Marky

Hi,

how can I call the "Frame All" from the popup menu from a SplineGUI ?
Because I have to update the ranges.

You can call SplineData::MakeLinearSplineLinear() or SplineData::MakeLinearSplineBezier(). In the SDK examples, HairStylingTag::Init() shows how to init a SplineData.

In what method of your plugin do you call AdaptRange() ?

Hi, thanks for the first point.

Relating to the second point, I like to change the range for the spline, not from 0 to 1 but -20 to +80. It's depend from 4 input properties (LONG values,  xmin, xmax, ymin and ymax). So I receive an message MSG_DESCRIPTION_CHECKUPDATE if something changed and than I like to adapt the range for the slides. I call the AdaptRange() function or/and also the SetRange() function but the GUI doesn't updated. Only if I select the "Frame All" from the popup menu.

Why do you need to adapt and/or set the range at a MSG_DESCRIPTION_CHECKUPDATE ?
You should only call AdaptRange() and/or SetRange() in Read() or Init() of your plugin to initialize SplineData range and get a GUI update.

I thought, if the user like to change the range of the spline GUI and he make some changes on other properties, than I can adapt the GUI. By the way, I don't have a Read() function in my plugin. Do you have an example for me ?

Take a look at the spline deformer shape. If you change the radius value, the spline is updated but not the X range. As you said before, to update it we have to open the spline in a new window or select "Frame All" menu item.
There's no 'coding way' with the SDK to refresh the ranges.
