Hi JoshyFun, in this context, maybe have a look at: http://bugs.freepascal.org/view.php?id=10665 I don't know if it overlaps with your plans, or is unrelated...

As I understand GetValue will return the default value representation so to add override representation, in example memory dump, a new function should be added like GetValue(FormatSet). 2) The IDE hints are always draw using DT_CENTER which ruins any multiline representation. Is possible to remove this DT_CENTER from procedure THintWindow.Paint ? 3) In the case of class debug I had added to the result the data returned from evaluating de dereference, something like inspecting Class and Class^ which offers more information. Are this kind of improvements of some interest ? 4) gdb class information looks very strange to me, in example a TMemoryStream dumps: ~type = TMEMORYSTREAM = class : public TCUSTOMMEMORYSTREAM \n ~ private\n ~FCAPACITY : LONGINT;\n ~\n ~ public\n ~procedure SETCAPACITY (TMEMORYSTREAM, ONGINT, );\n ~function REALLOC (TMEMORYSTREAM, ONGINT, ) : POINTER; virtual;\n ~destructor ~DESTROY (TMEMORYSTREAM, OINTER); virtual;\n ~procedure CLEAR (TMEMORYSTREAM);\n ~procedure LOADFROMSTREAM (TMEMORYSTREAM, STREAM, );\n ~procedure LOADFROMFILE (TMEMORYSTREAM, ANSISTRING);\n ~procedure SETSIZE (TMEMORYSTREAM, ONGINT, ); virtual;\n ~function WRITE (TMEMORYSTREAM, onst7, ) : LONGINT; virtual;\n ~end\n Note the missing L in second parameter when LONGINT was expected, or missing T in LOADFROMSTREAM, but the most strange to me is the onst7. What's const7 ? Does anybody know why those letters are missing ? 5) When an exception is raised and stop button is pressed usually the assembler window pops up instead the line where the exception happends, or the nearest line with debug information. I had changed my code to show the assembler window only if no line with debug information is found in the backtrace. But I do not exactly know how that procedure works and maybe I missed something important, or maybe that's the expected behavior :-? -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
