Brief Description

Base class for different kinds of buttons.

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 ( )

This signal is emitted every time the button is toggled or pressed (i.e. activated, so on button_down if “Click on press” is active and on button_up otherwise).

  • toggled ( bool button_pressed )

This signal is 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

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.

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

Setter set_action_mode(value)
Getter get_action_mode()

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

  • int button_mask
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, set this to 3, because it’s BUTTON_MASK_LEFT | BUTTON_MASK_RIGHT.

Setter set_disabled(value)
Getter is_disabled()

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

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).

Setter set_button_group(value)
Getter get_button_group()

ButtonGroup associated to the button.

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).

Setter set_shortcut(value)
Getter get_shortcut()

ShortCut associated to the button.

  • bool shortcut_in_tooltip
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.

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.

  • void _toggled ( bool button_pressed ) virtual

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

Return 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.

  • bool is_hovered ( ) const

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