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.

@mulfycrowh
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

@mulfycrowh
Use the setHtml ?

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.

You are right but with <br> it perfectly runs !
