QTextEdit::setTextFormat(Qt::LogText) does not exist anymore, what else can I use to log?

Question

I need a text logger in my C++ application, QTextEdit used to have this feature until Qt 3.3 but unfortunately it has been removed. Is there an alternative that I could use?

Answer 1

Two options:

1. You could simply use QTextEdit::setReadOnly(true), the old Qt::LogText flag basically just put the QTextEdit in plain-text read-only mode.
2. Or use Q3TextEdit, the Qt4 compatibility class for the old Qt3 QTextEdit.

Thanks a lot, I did not know Q3TextEdit existed, I will use it. – Spearmint

@ user363778 - Instead of using Q3TextEdit, it's better if you use QTextEdit in the above way. From Qt documentation - "We strongly advise against using it (Q3TextEdit) in new code." – Testy

Answer 2

It seems to me that QPlainTextEdit is what you are looking for.

It is optimized for dealing with plain text data and can be can put it in read only.
