ItemList

Inherits: Control < CanvasItem < Node < Object

Control that provides a list of selectable items (and/or icons) in a single column, or optionally in multiple columns.

Description

This control provides a selectable list of items that may be in a single (or multiple columns) with option of text, icons, or both text and icon. Tooltips are supported and may be different for every item in the list.

Selectable items in the list may be selected or deselected and multiple selection may be enabled. Selection with right mouse button may also be enabled to allow use of popup context menus. Items may also be "activated" by double-clicking them or by pressing Enter.

Item text only supports single-line strings, newline characters (e.g. \n) in the string won't produce a newline. Text wrapping is enabled in ICON_MODE_TOP mode, but column's width is adjusted to fully fit its content by default. You need to set fixed_column_width greater than zero to wrap the text.

All set_* methods allow negative item index, which makes the item accessed from the last one.

Incremental search: Like PopupMenu and Tree, ItemList supports searching within the list while the control is focused. Press a key that matches the first letter of an item's name to select the first item starting with the given letter. After that point, there are two ways to perform incremental search: 1) Press the same key again before the timeout duration to select the next item starting with the same letter. 2) Press letter keys that match the rest of the word before the timeout duration to match to select the item in question directly. Both of these actions will be reset to the beginning of the list if the timeout duration has passed since the last keystroke was registered. You can adjust the timeout duration by changing ProjectSettings.gui/timers/incremental_search_max_interval_msec.

Signals

  • empty_clicked ( Vector2 at_position, int mouse_button_index )

Triggered when any mouse click is issued within the rect of the list but on empty space.

  • item_activated ( int index )

Triggered when specified list item is activated via double-clicking or by pressing Enter.

  • item_clicked ( int index, Vector2 at_position, int mouse_button_index )

Triggered when specified list item has been clicked with any mouse button.

The click position is also provided to allow appropriate popup of context menus at the correct location.

  • item_selected ( int index )

Triggered when specified item has been selected.

Enumerations

enum IconMode:

  • ICON_MODE_TOP = 0 --- Icon is drawn above the text.

  • ICON_MODE_LEFT = 1 --- Icon is drawn to the left of the text.

enum SelectMode:

  • SELECT_SINGLE = 0 --- Only allow selecting a single item.

  • SELECT_MULTI = 1 --- Allows selecting multiple items by holding Ctrl or Shift.

Property Descriptions

  • bool allow_reselect

Default

false

Setter

set_allow_reselect(value)

Getter

get_allow_reselect()

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

  • bool allow_rmb_select

Default

false

Setter
