Initializing arrays


Array's are initialized very simply in Delphi. The initialization of an array of TStyleRecord's:


TStyleRecord = record
  Name    : string;
  Style   : TFontStyles;
end;

could look like:


DefaultStyles : TStylesArray = (
 (Name : 'tnone';    Style :  []),
 (Name : 'tstring';  Style :  []),
 (Name : 'tcomment'; Style :  [fsItalic])
);

This was translated in the earlier versions of Delphi2Cpp as:


TStylesArray DefaultStyles = { 
     { "tnone" /*Name*/, arrays__0 /*Style*/ },
     { "tstring" /*Name*/, arrays__1 /*Style*/ },
     { "tcomment" /*Name*/, arrays__2 /*Style*/ } 
    };

It is a problem however, that such initializations are only possible, if the elements are built in types of C. Such initializations of elements of the type TFontStyle aren't permitted. Beginning with version 1.2.4., Delphi2Cpp therefore generates initialization functions which are called within the initialization routine of the corresponding unit (see above).


void DefaultStylesInit( )
{
  DefaultStyles[0].Name = "tnone";
  DefaultStyles[0].Style = arrays__0;
  DefaultStyles[1].Name = "tstring";
  DefaultStyles[1].Style = arrays__1;
  DefaultStyles[2].Name = "tcomment";
  DefaultStyles[2].Style = arrays__2;
}
