Problem getting richtext out of QTextEdit
Message 1 in thread
Hello,
I am having trouble using the QTextEdit class. I am trying to write a
rather specialised word processor with this class. The problem that I am
having is that if I send in text marked up as "Rich text" I am unable to get
at the original marked up text. It seems as though there should be a way to
do this but I cannot find any information in the documentation from QT. I
have included a sample program with this email that illustrates the problem,
allong with a simplistic makefile that may be useful on a Linux system. I am
using QT 3.0, on a laptop running Red Hat 7.1. Also, I am curious as to why
I cannot edit the table that is being created?
In the end I will need to be able to load, edit, save, print, etc files
using unicode characters from various different languages, and even though
the sample program is rather simplistic, I have a pretty good start on the
actual program. I have used QT for an opengl project for a class that I took
last semester, but otherwise have very little QT experiance and very little
GUI experiance so any advice would be welcome, especially where to find
additional documentation.
Thank you for your time,
John Pitz

In the sixth paragraph of the QTextEdit documentation,
there is a line that says:
"If you create a new QTextEdit, and want to allow the
user to edit rich text, call setTextFormat(Qt::RichText)
to ensure that the text is treated as rich text."
So, if you add setTextFormat(Qt::RichText) to your
constructor, it will spit out the Rich Text.
