PostWmOnAttribChanged

The callback PostWmOnAttribChanged (CENPyOlpWM_AttribChangedOperator) is called from the kernel when a workmethod attribute has been changed.

It can be used to:

  • get world reference matrix

  • get attribute values

  • set attribute values

  • output to the log

  • access OlpController

  • access csv files

The callback is defined in the %WORKMETHOD_NAME%.py file that is located in the scripts folder of the plugin.

testEnumName = "TestEnum"
testString1Name = "testString1"
myliterals = ['A','B','C']
def PostWmInitAttributes(Operator):
   attribCreator.AddEnum(testEnumName, myliterals, myliterals[0], USER_ATTRIBUTE | PROCESS_ATTRIBUTE | OPERATION_GROUP_ATTRIBUTE, testEnumName)
   attribCreator.AddString(testString1Name, myliterals[0], USER_ATTRIBUTE | PROCESS_ATTRIBUTE | OPERATION_GROUP_ATTRIBUTE, testString1Name)
 
def PostWmOnAttribChanged(Operator):
   attribGetter = Operator.GetAttribGetter()
   attribSetter = Operator.GetAttribSetter()
   changedAttribute = Operator.GetChangedAttribute()
   changedAttributeName = changedAttribute.GetName()
   if testEnumName == changedAttributeName:
       testEnumValue = attribGetter.GetEnumIndex(testEnumName)
       attribSetter.SetString(testString1Name, myliterals[testEnumValue])
