Added 4 new methods for Windows:

procedure Print(const DocumentTitle: string; Margins :TMargins);   
procedure Redo;

Added 2 more properties:

CaretCoordinates
Column :Integer
Line :Integer

CaretPoint

Y :Integer

There is an issue in Linux with an Access Violation when one reopens a project with lzRichEdit component on a form.

Thanks.

feedback ***: win7 64 bit  from the demo provided
saves as expected *.rtf and *.html
load as expected *.rtf
print as expected
font change (name,size)as expected
formating as expected
printing as expected
issues:
when searching non english chars the selection mask is doubled
ex: if the string is [astring] and the search term is 'as' the text is found and 2 chars 'a' and 's' are selected
      if the string in editor is 'ασδερτασδ' and the search term is 'ασδ' then the selected text is 'ασδερτ'
when searching non english and english chars the selection mask is doubled/2
ex:
      if the string in editor is 'aαααα' and the search term is 'aα' then the selected text is 'aαα'
@typo congrats great job

Thanks for the feedback.

Feedback for Linux is also welcome.

Solution for the issue on Windows: find this line of code in the Example Project:

Code: [Select]
SelLength := Length(FindDlg.FindText);

and replace it by that:

Code: [Select]
SelLength := UTF8Length(FindDlg.FindText);

Thanks.

Steps
open a txt file ex: test1.txt
edit the file ex: set one line align to center
save the file as rtf with name test1.rtf
open the new file test1.rtf
nothing is loaded
the file is saved thought as txt with the extension of rtf
you can confirm this if you open the file with another editor.
from time to time debuger crashes when clossing the app and in session several documntes where loaded but did not figure this out yet to spot exactly when it happens

I use win7-32bit and can not reproduce this. The file is saved with an extension RTF, but is plan text, I can open it on Notepad and there is no formatting info there.

(Unless you mean "no format" by "nothing".)

open a text file---> file/open
and save it as rtf--->file/save as (select rtf)
and open the saved rtf --->click on the  folder icon and select the saved rtf
nothing is loaded
and if you close the app from the
  • button top right you got a debugger crash

It seems that the control does not open an RTF extension with plain text inside it. You can try to change the extension of a text file from TXT to RTF. You could not open it, the control remains empty, even if you can open it in other apps.

The openfile/savefile routines are not working fine. It is not with the control itself.

With PlainText set to False, the plain text is not shown, no matter it has an extension TXT or RTF.
