  6. BaseButton
  7. ==========
  8. **Inherits:** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
  9. **Inherited By:** :ref:`Button<class_Button>`, :ref:`LinkButton<class_LinkButton>`, :ref:`TextureButton<class_TextureButton>`
  10. Base class for different kinds of buttons.
  11. Description
  12. -----------
  13. 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.

  52. Signals
  53. -------
  54. .. _class_BaseButton_signal_button_down:
  55. - **button_down** **(** **)**
  56. Emitted when the button starts being held down.
  57. ----
  58. .. _class_BaseButton_signal_button_up:

  165. +-----------+--------------------+
  166. | *Getter* | is_pressed() |
  167. +-----------+--------------------+
  168. 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``.
  169. **Note:** Setting :ref:`pressed<class_BaseButton_property_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>`.

  190. ----

  201. Method Descriptions
  202. -------------------
  203. .. _class_BaseButton_method__pressed:
  204. - void **_pressed** **(** **)** |virtual|
  205. 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.
  206. ----
  207. .. _class_BaseButton_method__toggled:
  208. - void **_toggled** **(** :ref:`bool<class_bool>` button_pressed **)** |virtual|
  209. Called when the button is toggled (only if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active).
  210. ----
  211. .. _class_BaseButton_method_get_draw_mode:
  212. - :ref:`DrawMode<enum_BaseButton_DrawMode>` **get_draw_mode** **(** **)** |const|
  213. 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.
  214. ----
  215. .. _class_BaseButton_method_is_hovered:
  216. - :ref:`bool<class_bool>` **is_hovered** **(** **)** |const|
  217. Returns ``true`` if the mouse has entered the button and has not left it yet.
  218. ----
  219. .. _class_BaseButton_method_set_pressed_no_signal:
  220. - void **set_pressed_no_signal** **(** :ref:`bool<class_bool>` pressed **)**
  221. Changes the :ref:`pressed<class_BaseButton_property_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``.
  222. **Note:** This method doesn't unpress other buttons in its button :ref:`group<class_BaseButton_property_group>`.
  223. .. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
  224. .. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
  225. .. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
