        This function specifies if an elementary symbol is active or inactive.
      - hook_<libraryPrefix>_faceplateHeadline()
        This function specifies the text for the header of a faceplate.
      - hook_<libraryPrefix>_faceplateWindowTitle()
        This function queries the text of the faceplate window title of the referenced data point.
      - hook_<libraryPrefix>_hasUserAuthorization()
        This function determines whether a certain user has the authorization to change the value of a data point element.
      - hook_<libraryPrefix>_highlightElementarySymbol()
        This function determines whether an elementary symbol is highlighted.
      - hook_<libraryPrefix>_namingFaceplateTabs()
        This function determines the titles for the tabs in a faceplate.
      - hook_<libraryPrefix>_objectTooltip()
        This function determines the tool tip text of a symbol.
      - hook_<libraryPrefix>_openFaceplate()
        This function opens the faceplate of a symbol.
      - hook_<libraryPrefix>_projectFillPopUpMenu()
        This function configures the context menu of a symbol and elementary symbols of a faceplate.

hook_<libraryPrefix>_highlightElementarySymbol()

This function determines whether an elementary symbol is highlighted.

Synopsis

bool hook_<libraryPrefix>_highlightElementarySymbol(string sDpe);

Parameter


Parameter	Description
sDpe	Name of the datapoint element to which the elementary symbol references.

Return Value

TRUE = Elementary symbol is highlighted

FALSE = Elementary symbol is not highlighted

Description

This function determines whether an elementary symbol is highlighted.

Note that if a rule has already been created for this element, the rule is then combined with this function by using OR.

By default, all elementary symbols in the faceplate are not highlighted.

You can find the function in the stdlib_hook_project.ctl under wincc_oa_path/Stdlib_3.20/scripts/libs/

bool hook_highlightElementarySymbol (string sDpe, string sUser="")
{
  //  if(sUser=="")
  //    sUser = getUserName();
  return false;
}
