The callback PostWmInitAttributes(CENPyOlpWM_AttribInitOperator) is called just after the kernel initializes the technology attributes.
It can be used to:
- initialize attributes
- get attribute values
- set attribute values
- access OlpController
- output to the log
The callback is defined in the %WORKMETHOD_NAME%.py file that is located in the scripts folder of the plugin.
[Example]
def PostWmInitAttributes(wmAttribInitOperator):
# Create attributes
attribCreator = wmAttribInitOperator.GetAttribCreator() # get object of CENPyOlpAttribCreator class
attribCreator.AddInteger('rsAttribute', 0, -100, 0, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'rsAttribute')
attribCreator.AddDouble('rsDoubleAttribute', 55.5, 0, 100, 0.5, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, ATTRIB_STANDARD, 'rsDoubleAttribute')
attribCreator.AddString('rsStringAttribute', 'Hello World', USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'rsStringAttribute')
attribCreator.AddBool('rsBoolAttribute', True, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'rsBoolAttribute')
myLiterals = ["mo", "di", "mi"] # list of three literals
attribCreator.AddEnum('rsEnumAttribute', myLiterals, 'di', USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'rsEnumAttribute')
# Get values from attributes
attribGetter = wmAttribInitOperator.GetAttribGetter()
indexOfMyEnumAttrib = attribGetter.GetEnumIndex('rsEnumAttribute')
# Output attribute value to the log
logOperator = wmAttribInitOperator.GetLoggerOperator()
logOperator.LogDebug('indexOfMyEnumAttrib = ' + str(indexOfMyEnumAttrib))
# Create system attributes
sysAttribCreator = attribCreator.GetSystemAttribCreator()
min_radius = sysAttribCreator.AddMinRadius(8.8, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE | OPERATION_ATTRIBUTE)
max_radius = sysAttribCreator.AddMaxRadius(2.2, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE | OPERATION_ATTRIBUTE)
As a result, new attributes appear on the user interface:
