PostWmOnFrameChanged

The callback

PostWmOnFrameChanged

(

CENPyOlpFrameChangedOperator

) is called from the  kernel when the tool or base frame was been changed at the operation level.

It can be used to:

  • get attribute values

  • set attribute values

  • output to the log

  • access OlpController

  • access SCV parser

  • get the full path to the technology table file

  • get newly changed frame name, index, type, matrix and world matrix

The callback may return a Boolean value. There is no need to return False, because the default value is False anyway:

  • True: if it is necessary to perform an operation recompute (ENTERSTATE_STARTWITHRULEEVENTS) after the callback ends

  • False: no recompute

The callback is defined in the

%WORKMETHOD_NAME%.py

file that is located in the scripts folder of the

plugin

.
