Signals
-------

.. _class_BaseButton_signal_button_down:

- **button_down** **(** **)**

Emitted when the button starts being held down.

- **button_up** **(** **)**

Emitted when the button stops being held down.

.. _class_BaseButton_signal_pressed:

- **pressed** **(** **)**

Emitted when the button was just toggled between pressed and normal states (only if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active). The new state is contained in the ``button_pressed`` argument.

- **ACTION_MODE_BUTTON_RELEASE** = **1** --- Require a press and a subsequent release before considering the button clicked.

Description
-----------

BaseButton is the abstract base class for buttons, so it shouldn't be used directly (it doesn't display anything). Other types of buttons inherit from it.

Property Descriptions
---------------------

.. _class_BaseButton_property_action_mode:

- :ref:`ActionMode<enum_BaseButton_ActionMode>` **action_mode**

+-----------+------------------------+
| *Default* | 1                      |
+-----------+------------------------+
| *Setter*  | set_action_mode(value) |
+-----------+------------------------+
| *Getter*  | get_action_mode()      |

Determines when the button is considered clicked, one of the ``ACTION_MODE_*`` constants.

.. _class_BaseButton_property_button_mask:

- :ref:`int<class_int>` **button_mask**

+-----------+------------------------+
| *Default* | 1                      |
+-----------+------------------------+
| *Setter*  | set_button_mask(value) |
+-----------+------------------------+
| *Getter*  | get_button_mask()      |
+-----------+------------------------+

Binary mask to choose which mouse buttons this button will respond to.

To allow both left-click and right-click, use ``BUTTON_MASK_LEFT | BUTTON_MASK_RIGHT``.

.. _class_BaseButton_property_disabled:

- :ref:`bool<class_bool>` **disabled**

+-----------+---------------------+
| *Default* | false               |
+-----------+---------------------+
| *Setter*  | set_disabled(value) |
+-----------+---------------------+
| *Getter*  | is_disabled()       |
+-----------+---------------------+

If ``true``, the button is in disabled state and can't be clicked or toggled.

.. _class_BaseButton_property_enabled_focus_mode:

- :ref:`FocusMode<enum_Control_FocusMode>` **enabled_focus_mode**

+-----------+-------------------------------+
| *Default* | 2                             |
+-----------+-------------------------------+
| *Setter*  | set_enabled_focus_mode(value) |
+-----------+-------------------------------+
| *Getter*  | get_enabled_focus_mode()      |
+-----------+-------------------------------+

Focus access mode to use when switching between enabled/disabled (see :ref:`Control.focus_mode<class_Control_property_focus_mode>` and :ref:`disabled<class_BaseButton_property_disabled>`).

.. _class_BaseButton_property_group:

- :ref:`ButtonGroup<class_ButtonGroup>` **group**

+-----------+-------------------------+
| *Default* | null                    |
+-----------+-------------------------+
| *Setter*  | set_button_group(value) |
+-----------+-------------------------+

+-----------+-------------------------+

:ref:`ButtonGroup<class_ButtonGroup>` associated to the button.

.. _class_BaseButton_property_keep_pressed_outside:

- :ref:`bool<class_bool>` **keep_pressed_outside**

+-----------+---------------------------------+
| *Default* | false                           |
+-----------+---------------------------------+

+-----------+---------------------------------+

If ``true``, the button stays pressed when moving the cursor outside the button while pressing it.

.. _class_BaseButton_property_toggle_mode:

- :ref:`bool<class_bool>` **toggle_mode**

+-----------+------------------------+
| *Default* | false                  |
+-----------+------------------------+
| *Setter*  | set_toggle_mode(value) |
+-----------+------------------------+
| *Getter*  | is_toggle_mode()       |
+-----------+------------------------+

If ``true``, the button is in toggle mode. Makes the button flip state between pressed and unpressed each time its area is clicked.

Method Descriptions
-------------------

.. _class_BaseButton_method__pressed:

- void **_pressed** **(** **)** virtual

Called when the button is pressed.

.. _class_BaseButton_method__toggled:

- void **_toggled** **(** :ref:`bool<class_bool>` button_pressed **)** virtual

Called when the button is toggled (only if toggle_mode is active).

.. _class_BaseButton_method_get_draw_mode:

- :ref:`DrawMode<enum_BaseButton_DrawMode>` **get_draw_mode** **(** **)** const

Returns the visual state used to draw the button. This is useful mainly when implementing your own draw code by either overriding _draw() or connecting to "draw" signal. The visual state of the button is defined by the ``DRAW_*`` enum.

.. _class_BaseButton_method_is_hovered:

- :ref:`bool<class_bool>` **is_hovered** **(** **)** const

Returns ``true`` if the mouse has entered the button and has not left it yet.
