@QStringList wordList;
wordList << "alpha" << "omega" << "omicron" << "zeta";

QLineEdit *lineEdit = new QLineEdit(this);

QCompleter *completer = new QCompleter(wordList, this);
completer->setCaseSensitivity(Qt::CaseInsensitive);
lineEdit->setCompleter(completer);@

The "wordList" would simply be the list of recently used commands.

Also check the available QCompleter::CompletionMode values!

Should not be required, I think.

Just connect a signal to QLineEdit::retrunPressed(). This will tell you when the user has typed a new command into the LineEdit. Then just do whatever needs to be done and append the desired output (logging) into the QPlainTextEdit. For details see "Signals and Slots":http://qt-project.org/doc/qt-4.8/signalsandslots.html

Make the QPlainTextEdit read-only.
