Signals
-------

-  **text_changed**  **(** :ref:`String<class_string>` text  **)**
When the text changes, this signal is emitted.

-  **text_entered**  **(** :ref:`String<class_string>` text  **)**
This signal is emitted when the user presses KEY_ENTER on the :ref:`LineEdit<class_lineedit>`. This signal is often used as an alternate confirmation mechanism in dialogs.
