Salut Bernard,
When creating the parameter with AddParameter3, use the default values (in Python, use None) for Min and Max:
"Minimum value of the custom parameter. ... For all other numerical type the default will be minimum value possible for the type ..."
"Maximum value of the custom parameter. ... For all other numerical type the default will be minimum value possible for the type ..."
Once the parameter is created, you can retrieve the actual values with the Parameter object properties Min and Max.
For example (in Python):
from win32com.client import constants as xsi
XSI = Application
prop = XSI.ActiveSceneRoot.AddCustomProperty( "MyCustomProp" )
paramInt4 = prop.AddParameter3( "Int4", xsi.siInt4, 0, None, None )
XSI.LogMessage( "Int4 Min = %d" % paramInt4.Min )
XSI.LogMessage( "Int4 Max = %d" % paramInt4.Max )
paramFloat = prop.AddParameter3( "Float", xsi.siFloat, 0.0, None, None )
XSI.LogMessage( "Float Min = %e" % paramFloat.Min )
XSI.LogMessage( "Float Max = %e" % paramFloat.Max )
logs on my workstation:
#INFO : Int4 Min = -2147483648
#INFO : Int4 Max = 2147483647
#INFO : Float Min = -3.402823e+38
#INFO : Float Max = 3.402823e+38
Cheers,
François
