	<brief_description>
		Control that provides a list of selectable items (and/or icons) in a single column, or optionally in multiple columns.
	</brief_description>
	<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 [kbd]Enter[/kbd].
		Item text only supports single-line strings, newline characters (e.g. [code]\n[/code]) in the string won't produce a newline. Text wrapping is enabled in [constant ICON_MODE_TOP] mode, but column's width is adjusted to fully fit its content by default. You need to set [member fixed_column_width] greater than zero to wrap the text.
		All [code]set_*[/code] methods allow negative item index, which makes the item accessed from the last one.
		[b]Incremental search:[/b] 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 [member ProjectSettings.gui/timers/incremental_search_max_interval_msec].
