OptionButton¶

Inherits: Button < BaseButton < Control < CanvasItem < Node < Object

A button that brings up a dropdown with selectable options when pressed.

Description¶

OptionButton is a type of button that brings up a dropdown with selectable items when pressed. The item selected becomes the "current" item and is displayed as the button text.

See also BaseButton which contains common properties and methods associated with this node.

Note: The ID values used for items are limited to 32 bits, not full 64 bits of int. This has a range of -2^32 to 2^32 - 1, i.e. -2147483648 to 2147483647.

Note: The Button.text and Button.icon properties are set automatically based on the selected item. They shouldn't be changed manually.

Signals¶

item_focused ( int index )

Emitted when the user navigates to an item using the ProjectSettings.input/ui_up or ProjectSettings.input/ui_down input actions. The index of the item selected is passed as argument.

item_selected ( int index )

Emitted when the current item has been changed by the user. The index of the item selected is passed as argument.

allow_reselect must be enabled to reselect an item.

Property Descriptions¶

bool allow_reselect = false

void set_allow_reselect ( bool value )
bool get_allow_reselect ( )

If true, the currently selected item can be selected again.

bool fit_to_longest_item = true

void set_fit_to_longest_item ( bool value )
bool is_fit_to_longest_item ( )

If true, minimum size will be determined by the longest item's text, instead of the currently selected one's.

Note: For performance reasons, the minimum size doesn't update immediately when adding, removing or modifying items.

int item_count = 0

void set_item_count ( int value )
int get_item_count ( )

The number of items to select from.

int selected = -1

int get_selected ( )

The index of the currently selected item, or -1 if no item is selected.

Method Descriptions¶

void add_icon_item ( Texture2D texture, String label, int id=-1 )

Adds an item, with a texture icon, text label and (optionally) id. If no id is passed, the item index will be used as the item's ID. New items are appended at the end.

void add_item ( String label, int id=-1 )

Adds an item, with text label and (optionally) id. If no id is passed, the item index will be used as the item's ID. New items are appended at the end.

void add_separator ( String text="" )

Adds a separator to the list of items. Separators help to group items, and can optionally be given a text header. A separator also gets an index assigned, and is appended at the end of the item list.

void clear ( )

Clears all the items in the OptionButton.

Texture2D get_item_icon ( int idx ) const

Returns the icon of the item at index idx.

int get_item_id ( int idx ) const

Returns the ID of the item at index idx.
