Use the StyleSheetHideParameters method to hide specified task parameters in a workflow step.


See Callback Example: Show and Hide Task Parameters.


ENVIWorkflowStep.StylesheetHideParameters, StyleSheet, Parameters [, ERROR=value]



Specify a variable name for a style sheet (in the form of an IDL hash) that ENVI will pass to this method. When you use the CALLBACK_APPLY_STYLESHEET property in ENVIWorkflowStep in combination with the StyleSheetHideParameters method, ENVI will modify the style sheet hash accordingly.


Specify a string or array of strings with the task parameters to hide.



Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
