Signals
-------

.. _class_BaseButton_signal_button_down:

.. rst-class:: classref-signal

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

Emitted when the button starts being held down.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_signal_button_up:

.. rst-class:: classref-signal

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

Emitted when the button stops being held down.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_signal_pressed:

.. rst-class:: classref-signal

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

Emitted when the button is toggled or pressed.

.. rst-class:: classref-property

:ref:`ActionMode<enum_BaseButton_ActionMode>` **action_mode** = ``1``

.. rst-class:: classref-property-setget

- void **set_action_mode** **(** :ref:`ActionMode<enum_BaseButton_ActionMode>` value **)**
- :ref:`ActionMode<enum_BaseButton_ActionMode>` **get_action_mode** **(** **)**

Determines when the button is considered clicked, one of the :ref:`ActionMode<enum_BaseButton_ActionMode>` constants.

.. rst-class:: classref-item-separator

----

- void **set_button_group** **(** :ref:`ButtonGroup<class_ButtonGroup>` value **)**
- :ref:`ButtonGroup<class_ButtonGroup>` **get_button_group** **(** **)**

The :ref:`ButtonGroup<class_ButtonGroup>` associated with the button. Not to be confused with node groups.

\ **Note:** The button will be configured as a radio button if a :ref:`ButtonGroup<class_ButtonGroup>` is assigned to it.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_button_mask:

.. rst-class:: classref-property

:ref:`MouseButtonMask<enum_@GlobalScope_MouseButtonMask>` **button_mask** = ``1``

.. rst-class:: classref-property-setget

- void **set_button_mask** **(** :ref:`MouseButtonMask<enum_@GlobalScope_MouseButtonMask>` value **)**
- :ref:`MouseButtonMask<enum_@GlobalScope_MouseButtonMask>` **get_button_mask** **(** **)**

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

To allow both left-click and right-click, use ``MOUSE_BUTTON_MASK_LEFT | MOUSE_BUTTON_MASK_RIGHT``.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_button_pressed:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **button_pressed** = ``false``

.. rst-class:: classref-property-setget

- void **set_pressed** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_pressed** **(** **)**

If ``true``, the button's state is pressed. Means the button is pressed down or toggled (if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active). Only works if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is ``true``.

\ **Note:** Setting :ref:`button_pressed<class_BaseButton_property_button_pressed>` will result in :ref:`toggled<class_BaseButton_signal_toggled>` to be emitted. If you want to change the pressed state without emitting that signal, use :ref:`set_pressed_no_signal<class_BaseButton_method_set_pressed_no_signal>`.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_disabled:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **disabled** = ``false``

.. rst-class:: classref-property-setget

- void **set_disabled** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_disabled** **(** **)**

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

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_keep_pressed_outside:

- void **set_keep_pressed_outside** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_keep_pressed_outside** **(** **)**

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

\ **Note:** This property only affects the button's visual appearance. Signals will be emitted at the same moment regardless of this property's value.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_shortcut:

.. rst-class:: classref-property

:ref:`Shortcut<class_Shortcut>` **shortcut**

.. rst-class:: classref-property-setget

- void **set_shortcut** **(** :ref:`Shortcut<class_Shortcut>` value **)**
- :ref:`Shortcut<class_Shortcut>` **get_shortcut** **(** **)**

:ref:`Shortcut<class_Shortcut>` associated to the button.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_shortcut_feedback:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **shortcut_feedback** = ``true``

.. rst-class:: classref-property-setget

- void **set_shortcut_feedback** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_shortcut_feedback** **(** **)**

If ``true``, the button will highlight for a short amount of time when its shortcut is activated. If ``false`` and :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is ``false``, the shortcut will activate without any visual feedback.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_shortcut_in_tooltip:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **shortcut_in_tooltip** = ``true``

- void **set_shortcut_in_tooltip** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_shortcut_in_tooltip_enabled** **(** **)**

If ``true``, the button will add information about its shortcut in the tooltip.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_property_toggle_mode:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **toggle_mode** = ``false``

.. rst-class:: classref-property-setget

- void **set_toggle_mode** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **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:

.. rst-class:: classref-method

void **_pressed** **(** **)** |virtual|

Called when the button is pressed. If you need to know the button's pressed state (and :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active), use :ref:`_toggled<class_BaseButton_method__toggled>` instead.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_method__toggled:

.. rst-class:: classref-method

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

Called when the button is toggled (only if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active).

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_method_get_draw_mode:

.. rst-class:: classref-method

: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 :ref:`DrawMode<enum_BaseButton_DrawMode>` enum.

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_method_is_hovered:

.. rst-class:: classref-method

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

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

.. rst-class:: classref-item-separator

----

.. _class_BaseButton_method_set_pressed_no_signal:

.. rst-class:: classref-method

void **set_pressed_no_signal** **(** :ref:`bool<class_bool>` pressed **)**

Changes the :ref:`button_pressed<class_BaseButton_property_button_pressed>` state of the button, without emitting :ref:`toggled<class_BaseButton_signal_toggled>`. Use when you just want to change the state of the button without sending the pressed event (e.g. when initializing scene). Only works if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is ``true``.

\ **Note:** This method doesn't unpress other buttons in :ref:`button_group<class_BaseButton_property_button_group>`.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
