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.
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.
Enumerations¶
enum IconMode:
IconMode ICON_MODE_TOP = 0
Icon is drawn above the text.
IconMode ICON_MODE_LEFT = 1
Icon is drawn to the left of the text.
enum SelectMode:
SelectMode SELECT_SINGLE = 0
Only allow selecting a single item.
SelectMode SELECT_MULTI = 1
Allows selecting multiple items by holding Ctrl or Shift.
Property Descriptions¶
bool allow_reselect = false
If true, the currently selected item can be selected again.
bool allow_rmb_select = false
If true, right mouse button click can select items.
bool auto_height = false
If true, the control will automatically resize the height to fit its content.
int fixed_column_width = 0
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.
Vector2i fixed_icon_size = Vector2i(0, 0)
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 = 1
The icon position, whether above or to the left of the text. See the IconMode constants.
float icon_scale = 1.0
The scale of icon applied after fixed_icon_size and transposing takes effect.
int item_count = 0
The number of items currently in the list.
int max_columns = 1
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 = 1
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 = false
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 = 0
void set_select_mode ( SelectMode value )
SelectMode get_select_mode ( )
Allows single or multiple item selection. See the SelectMode constants.
OverrunBehavior text_overrun_behavior = 3
void set_text_overrun_behavior ( OverrunBehavior value )
OverrunBehavior get_text_overrun_behavior ( )
Sets the clipping behavior when the text exceeds an item's bounding rectangle. See OverrunBehavior for a description of all modes.
