You need a slot in your dialog for the textChanged() signal from your edit
control, and a member variable to store the text.
Then you could write a getText() function in your dialog, or your dialog
could emit a signal passing a reference to the text.

Your pop-up should probably be a modal dialog.
Create a class RowDialog which inherits QDialog.
Give it private member variables for the edit control and for the text.
Write a slot function which connects to the textChanged() signal.
Write a getChoice() function to return the text.
In your main window do this:
RowDialog *dlg = new RowDialog(this, "rowdialog", true);
if ( dlg->exec() == QDialog::Accepted )
{
qDebug("The user chose %s", dlg->getChoice());
}
delete dlg;
