How to fill default text into QInputDialog

I am trying to fill the default text into LineEdit field of QInputDialog (like filling the old value to rename, for example). Here is the code:

  bool dialogResult;
  QInputDialog *renameDialog = new QInputDialog();
  renameDialog->setTextValue("Test"); // has no effect
  QString result = renameDialog->getText(0, "Rename Label", "New name:", QLineEdit::Normal,
                                         "", &dialogResult);
  if(result.length() > 0 && dialogResult) setText(result);

How can I set a value to InputDialog to make it filled by default?

You need to pass the default text as fifth parameter:

QString result = renameDialog->getText(0, "Rename Label", "New name:", QLineEdit::Normal,
                                       "DEFAULT TEXT", &dialogResult);

See also QInputDialog::getText():

... text is the default text which is placed in the line edit ...
