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.

Signals
item_activated ( int index )
Triggered when specified list item is activated via double-clicking or by pressing Enter.
item_rmb_selected ( int index, Vector2 at_position )
Triggered when specified list item has been selected via right mouse clicking.
The click position is also provided to allow appropriate popup of context menus at the correct location.
allow_rmb_select must be enabled.
item_selected ( int index )
Triggered when specified item has been selected.
allow_reselect must be enabled to reselect an item.
multi_selected ( int index, bool selected )
Triggered when a multiple selection is altered on a list allowing multiple selection.
nothing_selected ( )
Triggered when a left mouse click is issued within the rect of the list but on empty space.
rmb_clicked ( Vector2 at_position )
Triggered when a right mouse click is issued within the rect of the list but on empty space.
allow_rmb_select must be enabled.
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 | set_allow_rmb_select(value) |
| Getter | get_allow_rmb_select() |
If true, right mouse button click can select items.
bool auto_height
| Default | false |
| Setter | set_auto_height(value) |
| Getter | has_auto_height() |
If true, the control will automatically resize the height to fit its content.
int fixed_column_width
| Default | 0 |
| Setter | set_fixed_column_width(value) |
| Getter | get_fixed_column_width() |
The width all columns will be adjusted to.
A value of zero disables the adjustment, each item will have a width equal to the width of its content and the columns will have an uneven width.
Vector2 fixed_icon_size
| Default | Vector2( 0, 0 ) |
| Setter | set_fixed_icon_size(value) |
| Getter | get_fixed_icon_size() |
The size all icons will be adjusted to.
If either X or Y component is not greater than zero, icon size won't be affected.
IconMode icon_mode
| Default | 1 |
| Setter | set_icon_mode(value) |
| Getter | get_icon_mode() |
The icon position, whether above or to the left of the text. See the IconMode constants.
float icon_scale
| Default | 1.0 |
| Setter | set_icon_scale(value) |
| Getter | get_icon_scale() |
The scale of icon applied after fixed_icon_size and transposing takes effect.
int max_columns
| Default | 1 |
| Setter | set_max_columns(value) |
| Getter | get_max_columns() |
Maximum columns the list will have.
If greater than zero, the content will be split among the specified columns.
A value of zero means unlimited columns, i.e. all items will be put in the same row.
int max_text_lines
| Default | 1 |
| Setter | set_max_text_lines(value) |
| Getter | get_max_text_lines() |
Maximum lines of text allowed in each item. Space will be reserved even when there is not enough lines of text to display.
Note: This property takes effect only when icon_mode is ICON_MODE_TOP. To make the text wrap, fixed_column_width should be greater than zero.
bool same_column_width
| Default | false |
| Setter | set_same_column_width(value) |
| Getter | is_same_column_width() |
Whether all columns will have the same width.
If true, the width is equal to the largest column width of all columns.
SelectMode select_mode
| Default | 0 |
| Setter | set_select_mode(value) |
| Getter | get_select_mode() |
Allows single or multiple item selection. See the SelectMode constants.
