Answer 1

I think you should take a look at this:
http://qt-project.org/doc/qt-4.8/tools-customcompleter.html

I used this example to understand CodeCompletion, and I think this is normal :)

[edit] Qt has its own class for this purpose called QCompleter: http://qt-project.org/doc/qt-4.8/qcompleter.html

Qt, , Tobias, - , . . , .

completeter lineEdit, ( QCompleter):

QStringList wordList;
wordList << "one" << "two" << "three" << "four" << "five";
QLineEdit *lineEdit = new QLineEdit(this);

QCompleter *completer = new QCompleter(wordList, this);
lineEdit->setCompleter(completer);

QPlainTextEdit QTextEdit setCompleter(), .
