BaseButton

Inherits: Control < CanvasItem < Node < Object

Inherited By: Button, LinkButton, TextureButton

Base class for different kinds of buttons.

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.

Methods

DrawMode

bool

is_hovered ( ) const

void

set_pressed_no_signal ( bool pressed )

Signals

button_down ( )

Emitted when the button starts being held down.

button_up ( )

Emitted when the button stops being held down.

pressed ( )

Emitted when the button is toggled or pressed. This is on button_down if action_mode is ACTION_MODE_BUTTON_PRESS and on button_up otherwise.

If you need to know the button's pressed state (and toggle_mode is active), use toggled instead.

toggled ( bool button_pressed )

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

Enumerations

enum DrawMode:

DrawMode DRAW_NORMAL = 0

The normal state (i.e. not pressed, not hovered, not toggled and enabled) of buttons.

DrawMode DRAW_PRESSED = 1

The state of buttons are pressed.

DrawMode DRAW_HOVER = 2

The state of buttons are hovered.

DrawMode DRAW_DISABLED = 3

The state of buttons are disabled.

DrawMode DRAW_HOVER_PRESSED = 4

The state of buttons are both hovered and pressed.

enum ActionMode:

ActionMode ACTION_MODE_BUTTON_PRESS = 0

Require just a press to consider the button clicked.

ActionMode ACTION_MODE_BUTTON_RELEASE = 1

Require a press and a subsequent release before considering the button clicked.

Property Descriptions

ActionMode action_mode = 1

Determines when the button is considered clicked, one of the ActionMode constants.

int button_mask = 1

  • void set_button_mask ( int value )

  • int 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.

bool disabled = false

  • void set_disabled ( bool value )

  • bool is_disabled ( )

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

FocusMode enabled_focus_mode = 2

Deprecated. This property has been deprecated due to redundancy and will be removed in Redot 4.0. This property no longer has any effect when set. Please use Control.focus_mode instead.

ButtonGroup group

ButtonGroup associated to the button.

bool keep_pressed_outside = false

  • void set_keep_pressed_outside ( bool value )

  • 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.

bool pressed = false

  • void set_pressed ( bool value )

  • bool is_pressed ( )

If true, the button's state is pressed. Means the button is pressed down or toggled (if toggle_mode is active). Only works if toggle_mode is true.

Note: Setting pressed will result in toggled to be emitted. If you want to change the pressed state without emitting that signal, use set_pressed_no_signal.

ShortCut shortcut

ShortCut associated to the button.

bool shortcut_in_tooltip = true

  • void set_shortcut_in_tooltip ( bool value )

  • bool is_shortcut_in_tooltip_enabled ( )

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

bool toggle_mode = false

  • void set_toggle_mode ( bool value )

  • 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

void _pressed ( ) virtual

Called when the button is pressed. If you need to know the button's pressed state (and toggle_mode is active), use _toggled instead.

void _toggled ( bool button_pressed ) virtual

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

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 DrawMode enum.

bool is_hovered ( ) const

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

void set_pressed_no_signal ( bool pressed )

Changes the pressed state of the button, without emitting 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 toggle_mode is true.

Note: This method doesn't unpress other buttons in its button group.
