I'm testing the capability of NextGrid with Unicode.
The NextGrid works fine, is very fast and small, but the Unicode works well on a TextualColumn but not on a NxHtmlColumn, is that correct?
Thanks

Hello,

Here is a fix. Open NxDisplays.pas file (located in Sources\Next Grid sub-folder).

Locate next procedure:

CODE

THtmlColumnDisplay.DrawHTML(HTML: WideString);

Add sub-procedure:

CODE

  procedure DrawTextOut(X, Y: Integer; Text: WideString);
  var
    StrText: string;
  begin
    if IsUnicodeSupported then Windows.ExtTextOutW(Canvas.Handle, X, Y, 0, nil,
      PWideChar(Text), Length(Text), nil) else
    begin
      StrText := Text;
      Windows.ExtTextOut(Canvas.Handle, X, Y, 0, nil, PChar(StrText),
        Length(StrText), nil);
    end;
  end;

Then, replace inside main procedure Canvas.TextOut with DrawTextOut (procedure we just created).

I hope that this is it

BUT, now another small problem.
When I use <b> </b> in part of the unicode text, and use some simbols like ☆☆☆ the grid don't shows the text correctly.
example: ☆☆☆☆☆ <b>ANDRE</b> ☆☆☆☆☆☆
(I use the font Lucida Sans Unicode)

Hello Boki
no problem... at the moment i can try to use only the color change.

One more ( i'm just trying to help to find the bugs ). Ok I don't know if it's a bug, but please check:

When I use:
TEXT1 <font color="#0000cc"><b>TEXT2</b></font> TEXT3

The TEXT3 is blue and don't use the normal color.

In my case I can "fix" using:
<font color="#000000">TEXT1</font> <font color="#0000cc"><b>TEXT2</b></font> <font color="#000000">TEXT3</font>

Thanks in advance

Andre

Hello Andre,

I will try to find fix for this now.

I will also upgrade html column in next days.

Best regards

[Andre Felix]

Boki,
Another thing to check is the size of font and font name. One of both seens to change when I use some HTML code.
thanks
Andre

The problem is another one... Sometimes I use only:
<font color="#595959">
and other times was:
<font name="Lucida Sams Unicode" color="#595959">

But it's the same font that i use in NextGrid. Maybe when I set the font name I have to set the font size?

Boki,
I have installed now the new version, but i didn't find the "{$IFDEF TNTUNICODE}, TntStdCtrls {$ENDIF};" on NxEdit.pas. Is no more needed?

Hello Andre,

Now is all in NxClasses.pas

Boki,

Very Nice

Is not possible to add a checkbox on installer for NX_DEBUG and TNTUNICODE? I know that I want to many things.. But it would be nice. I don't know if it's a good idea about the NX_DEBUG, but for TNTUNICODE....

Coming back about the NxHtmlColumn. It works for the symbols, but still have problems with some simbols and HTML code. As you can see, only when I add a HTML colde (to change de color), then i have that type of problem.

Andre

Hello Andre,

I will try to made this. I hope that it is possible to do this with Inno Setup (which I use for installer).

Can you please give me sample code you use for html column in your app. Somehow I can't get this special chars.

Best regards

[Andre Felix]

Boki,

Sorry for the late answer, but i have other things here to do.
About that simbols, I know that it's dificult to simulate. I'm using a webbrowser to read and add simbols like that in DB.
Please see the file:
maindemo_source.zip
If you want, you can put the value stored in grid on a TNTEdit to take a better look...

Regards,

Andre

Hello Andre,

I will check it now. Thank you. When I have some results, I'b be back here.
