// Method: QvisExpressionsWindow::newExpression
//
// Purpose: 
//   This is a Qt slot function that can be called on the window to add a
//   new expression and set the focus of the window to the name line edit
//   and select all of its text.
//
// Note:       This method is used by the "Create new expression ..." option
//             in QvisVariableButtons.
