Base class for different kinds of buttons. 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. Called when button is pressed. Called when button is toggled (only if toggle_mode is active). Return the current mode of action (see [method set_action_mode]) (one of the ACTION_MODE_* constants). 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. Returns focus access mode used when switching between enabled/disabled (see [method Control.set_focus_mode] and [method set_disabled]). Return whether the button is in disabled state (see [method set_disabled]). Return true if mouse entered the button before it exit. If toggle_mode is active, return whether the button is toggled. If toggle_mode is not active, return whether the button is pressed down. Return the toggle_mode property (see [method set_toggle_mode]). Set the current mode of action, determining when the button is considered clicked (see the ACTION_MODE_* constants). Set the button into disabled state. When a button is disabled, it can't be clicked or toggled. Sets the focus access mode to use when switching between enabled/disabled (see [method Control.set_focus_mode] and [method set_disabled]). Set the button to pressed state (only if toggle_mode is active). Set the button toggle_mode property. Toggle mode makes the button flip state between pressed and unpressed each time its area is clicked. Determines when the button is considered clicked, one of the ACTION_MODE_* constants. If [code]true[/code] the button is in disabled state and can't be clicked or toggled. Focus access mode to use when switching between enabled/disabled (see [method Control.set_focus_mode] and [member disabled]). [ButtonGroup] associated to the button. If [code]true[/code] the button's state is pressed. Means the button is pressed down or toggled (if toggle_mode is active). [Shortcut] associated to the button. If [code]true[/code] the button is in toggle mode. Makes the button flip state between pressed and unpressed each time its area is clicked. Emitted when the button starts being held down. Emitted when the button stops being held down. This signal is emitted every time the button is toggled or pressed (i.e. activated, so on [code]button_down[/code] if "Click on press" is active and on [code]button_up[/code] otherwise). 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 [i]pressed[/i] argument. The normal state (i.e. not pressed, not hovered, not toggled and enabled) of buttons. The state of buttons are pressed. The state of buttons are hovered. The state of buttons are disabled. Require just a press to consider the button clicked. Require a press and a subsequent release before considering the button clicked.
