QTextEdit::setTextFormat(Qt::LogText) does not exi

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.

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.
