ENVIView::Close

The Close method closes the view. Any layers within the view are also closed.

Note: ENVI must always have at least one open view. If you call the Close method for the final view, this view will not be removed.

Example

; Launch the application

e = ENVI()

; Open ENVIRaster and display it

file = FILEPATH('qb_boulder_msi', ROOT_DIR=e.ROOT_DIR, $

  SUBDIRECTORY = ['data'])

raster = e.OpenRaster(file)

view1 = e.GetView()

layer1 = view1.CreateLayer(raster)

; Create the second view and display raster

view2 = e.CreateView()

layer2 = view2.CreateLayer(raster, /CIR)

; Close the second view

view2.Close

Syntax

ENVIView.Close [, ERROR=variable]

Keywords

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.
