Entry widget is a single-line text entry widget. If the entered text is longer than the allocation of the widget, the widget will scroll so that the cursor position is visible.
Entry field can be converted in password mode using set_visibility() method of this class. Entered text is substituted by character chosen by invisible_char() method, default being ”*”.
The Entry class has the following constructor −
