It's doing a built-in tab insert. The way I override ctrl + i is to assign a popup menu with an item that has a ctrl + i shortcut assigned to it. Sergey might have another way but that's the only one I know.

My post above was just some test code to try and help the original poster. Not sure if what I tried will help him or not. Stan

I tried this and it seems to be working. I'm changing the bold this way: procedure TForm1.ToggleBold; begin if rve.GetItemStyle(rve.CurItemNo) <> 1 then rve.ApplyTextStyle(1) else rve.ApplyTextStyle(0); rve.Reformat; end; Then, using your function: function TextoRTF: string; var lRTF: TStringStream;...

I had forgotten about tables again. I'm not implementing them as such in my app but I do like to account for them in case I copy and paste one or more tables into my rve. I hadn't gotten quite as far as using CaretDrawItemNo but yes, that's the better way! I would have probably gotten to that eventu...

I tried this and it seems to work:

Code: Select all

procedure ScrollItemToTop(rve: TCustomRichViewEdit);
var
  DItem, DOffs: integer;
begin

  rve.RVData.Item2DrawItem(rve.CurItemNo, rve.OffsetInCurItem, DItem, DOffs );
  rve.ScrollToDrawItem( rve.RVData, DItem, false, false );
  rve.SetFocusSilent;

end;

Just a follow up. Sergey fixed this in the component so if you are using v20 you might want to turn the double buffering back on in the panels the rve is sitting on. I was having some issues with some canvas lineto code in my rve paint method and it was because I needed to re-enable the buffering. A...

I'm using a plain richviewedit with an rvprintpreview, but in that scenario, these work:

Code: Select all

RVPrintPreview1.ZoomMode := rvzmPageWidth ;
RVPrintPreview1.ZoomMode := rvzmFullPage ;

Maybe it's similar in the scale rv?

I've tried many PDF engines before choosing SynPDF... - You shouldn't rely on "MS PDF printer" which might not be installed on every computers, except if you control where you application is installed - Most other PDF engines I've tried but discarded due to bugs, limitations, lack of supp...

Thank u again:) I found TRVPrint export pdf worked fine:Just need set the margins property,so I avoided the problem.That's enough:) By the way,LLibPDF is not stable for me when I try to export many rvf files,SynPDF is perfect. I have bought the update license:) Interesting posts about exporting to ...

I doubt if you can do that with this component. Notepad++ uses Scintilla as the editing component. It's made for that kind of stuff (see https://www.scintilla.org/ScintillaDoc.html ). I think they call that rectangular selection. Scintilla is made more for code style editors, while the rich view is ...

This link has what I think you are after (if you want to do the code yourself):

Inverting the case is the ToggleCase function, and the cap each letter is the TitleCase function.

Makes sense, the srve probably "steals" the mouse message. Glad you got it working!

I tried the compiled ActionTests demo I have and there's no mousewheel action in it. I would assume it was compiled in delphi. I'm using a plain rve (not the scale version), but I found that in the app I'm currently working on that I had the best luck with putting mouse wheel code in the form: proce...

Hi Sergey and ChinaLer, I've tried both OnAfterDrawImage and tables. I'll put in a couple of screenshots below. The OnAfterDrawImage looks good, but there's a couple of things ChinaLer might need to keep in mind. The title is not (as far as I can tell) part of the image, so you have to figure out a ...

Thanks Sergey, that would be great.

FYI, even if the preview looks odd, it still prints OK.
