    Hi,

    I would like to display some rich text to QTextEdit but it doesn't work : it displays :

    {\rtf1\adeflang1025\ansi\ansicpg1252\uc1\adeff31507\deff0\stshfdbch31505\stshfloch31506\stshfhich31506\stshfbi31507\deflang3079\deflangfe3079\themelang3079\themelangfe0\themelangcs0{\fonttbl{\f0\fbidi \froman\fcharset0\fprq2{*\panose 02020603050405020304}Times New Roman;}{\f0\fbidi \froman\fcharset0\fprq2{*\panose 02020603050405020304}Times New Roman;}
    {\f39\fbidi \fswiss\fcharset0\fprq2{*\panose 020f0502020204030204}Calibri;}{\flomajor\f31500\fbidi \froman\fcharset0\fprq2{*\panose 02020603050405020304}Times New Roman;}
    {\fdbmajor\f31501\fbidi \froman\fcharset0\fprq2{*\panose

    ...

    I wrote:

    	ui.Text_About->setAcceptRichText(true);
    	QFile file("D:/Document.rtf");
    	file.open(QIODevice::ReadOnly | QIODevice::Text);
    	ui.Text_About->setText(file.readAll());
    	file.close();
    

    Many thanks for your help !

      Hi
      You should use
      http://doc.qt.io/qt-5/qtextedit.html#html-prop
      and look as the format it supports
      http://doc.qt.io/qt-5/richtext-html-subset.html

      I do not think it accept rich text as in RTF text, only html.
      So when docs says rich text it means text with formatting and NOT the rtf format.

        I already used html to change size, ... and it perfectly runs. The idea here was to use a RTF file generted by WordPad but as far I understand it is not possible.
        Thanks.

          Hi, I do not think it can parse and render traditional RTF at all.

          You can get a wonna-be WordPad with this example
          http://doc.qt.io/qt-5/qtwidgets-richtext-textedit-example.html

          I assume using wordpad was to provide a good editor.

            I've got another idea : writing the html sequence in a text file.
            If I use ->setPlainText(), it doesn't understand html sequences
            And if I use ->setText() it does understand thml sequences but without CRLF

                If I use

                	ui.Text_About->setAcceptRichText(true);
                	QFile file("D:/help.txt");
                	file.open(QIODevice::ReadOnly | QIODevice::Text);
                	ui.Text_About->setHtml(file.readAll());
                	file.close();
                

                the sequences html are well understood but there are no more CRLF. That's a trouble ...

                  well how are you making those line feeds?
                  With html, \n \r dont count as far as i know.

                  You must use <br> OR </p>

                    I just wrote it with Notepad.
                    Here are the very first lines:

                    <html><b>Format Generator</b></html>
                    <html><b>Developed by X - 09/17</b></html>
                    
                    
                    
                    <html><b>User's Manual</b></html>
                    
                    1/ Select Items Input Folder
                    This folder includes one item or several folders matching with various items.

                      Try using QTextEdit editor
                      Right click a textedit and select "Change HTML "
                      make the html there.
                      Then it will work.
                      Notepad and just pressing enter will not.
