Showing a error message

[srohit24]

Hi

I want to show a error message to the user by poping up a dialog box.

How can i do that using qdialog?

I have used this to accept input from the user

QString text = QInputDialog::getText(this, tr("Enter the username"),
                                          tr("User name:"), QLineEdit::Normal);

QString text = QInputDialog::getText(this, tr("Enter the username"),
                                          tr("User name:"), QLineEdit::Normal);

To copy to clipboard, switch view to plain text mode
