Using a Library's Logical Attribute Array with the Default Windows

The following default windows are used within Vermont Views:

• nFM_WNP, the default form window
  
  
• nMN_WNP, the default menu window
  
  
• nWN_WNP, the default window
  
  
• nMSG_WNP, the default message window
  
  
• nCLIST_WNP, the default choice list window
  
  
• nHELP_WNP, the default help window
  
  
• nERR_WNP, the default error message window
  
  
• nFULL_WNP, the full screen window used for clearing and saving the contents of the screen

In your Vermont Views application, these windows use the system logical attribute array (LATT_SYS) by default. That means that even if you are displaying a Designer form, the default windows are displayed using the attributes defined in LATT_SYS, not the Designer. If you want to specify that these windows use a logical attribute array used by one of your libraries, use the set environment window logical attributes function, se_wnlatt():

void se_wnlatt(libname_stp)

UCHAR *libname_stp;    /* Name of Designer library containing logical attribute array   */

The logical attribute array for the library name you specify must already be in the linked list. This means that either (1) the specified library is open or (2) a form still in memory is using the logical attribute array for the specified library. If the logical attribute array is not available and you are using a development library, an error is reported.
