//  Purpose:  This TEMPLATE file contains C++ source to guide you in the
//  construction of your Block application dialog. The generation of your
//  dialog file (.dlx extension) is the first step towards dialog construction
//  within NX.  You must now create a NX Open application that
//  utilizes this file (.dlx).
//
//  The information in this file provides you with the following:
//
//  1.  Help on how to load and display your Block UI Styler dialog in NX
//      using APIs provided in NXOpen.BlockStyler namespace
//  2.  The empty callback methods (stubs) associated with your dialog items
//      have also been placed in this file. These empty methods have been
//      created simply to start you along with your coding requirements.
//      The method name, argument list and possible return values have already
//      been provided for you.

//------------------------------- DIALOG LAUNCHING ---------------------------------
//
//    Before invoking this application one needs to open any part/empty part in NX
//    because of the behavior of the blocks.
//
//    Make sure the dlx file is in one of the following locations:
//        1.) From where NX session is launched
//        2.) $UGII_USER_DIR/application
//        3.) For released applications, using UGII_CUSTOM_DIRECTORY_FILE is highly
//            recommended. This variable is set to a full directory path to a file 
//            containing a list of root directories for all custom applications.
//            e.g., UGII_CUSTOM_DIRECTORY_FILE=$UGII_BASE_DIR\ugii\menus\custom_dirs.dat
//
//    You can create the dialog using one of the following way:
//
//    1. USER EXIT
//
//        1) Create the Shared Library -- Refer "Block UI Styler programmer‘s guide"
//        2) Invoke the Shared Library through File->Execute->NX Open menu.
