Answer 1

You can use setTabChangesFocus method of QTextEdit:

yourTextEdit.setTabChangesFocus(true);

Answer 2

You can subclass QTextEdit and override the keyPressEvent to intercept the tab key. Then, use nextInFocusChain to determine the next focus widget and call setFocus on it

Outline:

class MyTextEdit : public QTextEdit
{
public:
    MyTextEdit(QWidget *parent = 0) : QTextEdit(parent) {}

protected:
    void keyPressEvent(QKeyEvent *e) {
        if (e->key() == Qt::Key_Tab) {
            nextInFocusChain()->setFocus(Qt::TabFocusReason);
        } else {
            QTextEdit::keyPressEvent(e);
        }
    }
};
