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

void	_pressed ( ) virtual
void	_toggled ( bool button_pressed ) virtual
DrawMode	get_draw_mode ( ) const
bool	is_hovered ( ) const

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:

• DRAW_NORMAL = 0 --- The normal state (i.e. not pressed, not hovered, not toggled and enabled) of buttons.
• DRAW_PRESSED = 1 --- The state of buttons are pressed.
• DRAW_HOVER = 2 --- The state of buttons are hovered.
• DRAW_DISABLED = 3 --- The state of buttons are disabled.
• DRAW_HOVER_PRESSED = 4 --- The state of buttons are both hovered and pressed.

enum ActionMode:

• ACTION_MODE_BUTTON_PRESS = 0 --- Require just a press to consider the button clicked.
• ACTION_MODE_BUTTON_RELEASE = 1 --- Require a press and a subsequent release before considering the button clicked.

Property Descriptions

ActionMode action_mode

Default	1
Setter	set_action_mode(value)
Getter	get_action_mode()

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

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.

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.

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 Control.focus_mode and disabled).

ButtonGroup group

Setter	set_button_group(value)
Getter	get_button_group()

ButtonGroup associated to the button.

bool keep_pressed_outside

Default	false
Setter	set_keep_pressed_outside(value)
Getter	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

Default	false
Setter	set_pressed(value)
Getter	is_pressed()

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

ShortCut shortcut

Setter	set_shortcut(value)
Getter	get_shortcut()

ShortCut associated to the button.

bool shortcut_in_tooltip

Default	true
Setter	set_shortcut_in_tooltip(value)
Getter	is_shortcut_in_tooltip_enabled()

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

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

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.
