Install Addict Parser with C++ Builder XE

[nachbar]

I just purchased Addict Spell Checker to work with TRichView in C++ Builder XE. However, the addict parser does not have a package for C++ Builder XE, and the Readme does not reference C++ Builder XE.

Also, there appears to be an error in the Readme, where it says "Addict 3/4 packages must be changed before installing this package", but it does not say IN WHAT WAY they should be changed.

Can you advise the best way to use Addict with TRichView under C++ Builder XE?

Thanks!

"Explicit rebuild" option must be set for the Addict package. See my answer about rvHtmlViewImporter.

Thanks. For those finding this post in the future, the post referenced is at http://www.trichview.com/forums/viewtopic.php?p=19627

Note that "Explicit Rebuild" is set on the Options/Description tab (!) and appears to be the default for new C++ Builder XE Projects

Also, I take it from your answer that the ONLY change needed for the Addict 3/4 packages was the change to Explicit Rebuild. However, for C++ Builder, there is no building of Addict in the installation program. In opening the source Addict project for D15, I was prompted to update it for XE. Since I had not built the Addict project, I'm not sure that the build option will be relevant (since XE won't know how to rebuild Addict4 anyway!) Everything seems to work without changing the Addict project -- I will let you know if that changes.

Notes for anyone wanting to build the RichView Addict 4 Parser under C++ Builder XE:

Create a new package (File/New/Package -- C++ Builder) and save it

Add the following files to the package from the downloaded parser:
ad3RichView.pas
ad3RichViewCmpnts.pas
ad3RichVIewFast.pas

Add the following to the requires for the package:
C:\Users\Public\Documents\RAD Studio\8.0\Dcp\RVPkgCBXE.bpi
C:\Program Files (x86)\Addict4\BPL\addict4_d15.bpi

Set the following under Project/Options/Delphi Compiler/Compiling/Other Options/Additional options to pass to the compiler:
-LUDesignIDE

Activate the Release build, and build it. Right click the project and select "Install"

The Demo code for C++ Builder does not compile due to using AnsiStrings, and if you fix that, it fails to link because it references old versions of forms, so I have converted the C++ Builder demo for the TRichView Addict 4 Parser to work with C++ Builder XE:

Create a new C++ Builder XE Project, and drop a TRichViewEdit, TRVStyle, TPopupMenu, TButton, TAddictSpell, and TRVAddictSpell3.

Create the following handlers: FormCreate, RichViewEdit1KeyDown, Button1Click, RichViewEdit1SpellingCheck, RVAddictSpell31ParserIgnoreWord, PopupMenu1Popup

Copy american.adm and autocorrect.adu from Addict4/Dictionaries to the directory containing the .exe you will produce (if you don't, every word will be "misspelled")

Add to the public section of the TForm1 class definition in Unit1.h:

Code: Select all

void __fastcall PopupMenuItemClick(TObject *Sender);
void __fastcall PopupMenuAddToDictionaryClick(TObject *Sender);
void __fastcall PopupMenuIgnoreAllClick(TObject *Sender);

Add the following to the Unit1.cpp file, replacing the handlers created above:

Code: Select all

//---------------------------------------------------------------------------
void __fastcall TForm1::FormCreate(TObject *Sender)
{
  RichViewEdit1->Style = RVStyle1;
  RichViewEdit1->PopupMenu = PopupMenu1;

  RichViewEdit1->AddNLATag(
    "Speling contest - a kontest in wich you are elimineited if you fale to spel a vord corectly.", 0,0,0);
  RichViewEdit1->Format();
  RichViewEdit1->StartLiveSpelling();
  // remove this line for CB4
  PopupMenu1->AutoHotkeys = maManual;

}
//---------------------------------------------------------------------------

    RichViewEdit1->LiveSpellingValidateWord(RVAddictSpell31->CurrentWord);

    TStringList * sl = new TStringList;
    RVAddictSpell31->Suggest(wrd, sl);
    for (int i = 0; i<sl->Count; i++)
    {
      mi = new TMenuItem(PopupMenu1);
      mi->Caption = sl->Strings[i];
      mi->OnClick = PopupMenuItemClick;
      PopupMenu1->Items->Add(mi);
    }
    if (sl->Count == 0)
    {
      mi = new TMenuItem(PopupMenu1);
      mi->Caption = "(no suggestions)";
      mi->Enabled = false;
      PopupMenu1->Items->Add(mi);
    }

    mi = new TMenuItem(PopupMenu1);
    mi->Caption = "-";
    PopupMenu1->Items->Add(mi);

    mi = new TMenuItem(PopupMenu1);
    mi->Caption = "&Add to Dictionary";
    mi->OnClick = PopupMenuAddToDictionaryClick;

    mi = new TMenuItem(PopupMenu1);
    mi->Caption = "&Ignore All";
    mi->OnClick = PopupMenuIgnoreAllClick;

    delete sl;

}

// Clicking menu item - menu caption replaces the selected text

I did not find any demos or documentation for the TRVThesaurus3 parser to use the Addict Thesaurus component with TRichView. However, I was able to get functionality similar to the Thesaurus demo for Addict by creating another button to the demo above, and using the following line for the button handler:

RVThesaurus31->LookupRichViewEdit(RichViewEdit1);

Hopefully, I just missed the documentation and demos for the thesaurus -- if anyone knows where they are, please post that info here.

[Sergey Tkachenko]

Yes, your solution is correct. Just call LookupRichViewEdit.
If you use RichViewActions, you can use TrvActionAddictThesaurus3 as well.
