ENVI::Show

The Show method brings the ENVI application to the front and gives it focus. This can be useful in developing new scripts when the IDL Workbench may have focus and you want to bring the ENVI application to the front.

Example

; Launch application

e = ENVI()

 

; Click on Workbench

 

; Bring ENVI to front

e.Show

Syntax

ENVI.Show [, ERROR=variable]

Keywords

Keywords are applied only during the initial creation of the object.

ERROR

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.
