format_GetOptionList

Retrieve the list of options for a file format, as typically set by the CExtAPI::format_SetOptionValue function.

ZLIST CExtAPI::format_GetOptionList(ZFORMAT hFormat);

NULL if an error occurred, and a valid ZLIST handle otherwise.

This function can be used to retrieve format options that cannot be accessed by the CExtAPI::format_GetOptionValue function, namely classes such as ProgBox, map, ComboSelector, etc. These members can then be accessed using the CExtAPI::list_ functions.

// get the options list
ZLIST hOptions = theAPI.format_GetOptionList(hFormat);
if(!hOptions) {
  theAPI.ReportError("CL3DTio_HTFApp::SaveMapFile error:\r\n - cannot retrieve options list");
  return false;
}

...
	
if(hComboSel = theAPI.list_GetItemA(hOptions, "FlipAxes")) { // access list member by name
  CString SelStr;
  SelStr.SetString(theAPI.combosel_GetCurSel(hComboSel));
  if(SelStr.CompareNoCase("None")==0)	
    PackMode = HTF_INVERT_NONE;
  else
