Type members

Instance members

• var allowReselect: Bool

  If true, the currently selected cell may be selected again.

• var allowRmbSelect: Bool

  If true, a right mouse button click can select items.

• var allowSearch: Bool

  If true, allows navigating the Tree with letter keys through incremental search.

• var buttonClicked: Signal7

  Emitted when a button on the tree was pressed (see addButton(column:button:id:disabled:tooltipText:)).

• var cellSelected: SimpleSignal

  Emitted when a cell is selected.

• var checkPropagatedToItem: Signal6

  Emitted when propagateCheck(column:emitSignal:) is called. Connect to this signal to process the items that are affected when propagateCheck(column:emitSignal:) is invoked. The order that the items affected will be processed is as follows: the item that invoked the method, children of that item, and finally parents of that item.

• var columnTitleClicked: Signal9

  Emitted when a column’s title is clicked with either left or right.

• var columnTitlesVisible: Bool

  If true, column titles are visible.

• var columns: Int32

  The number of columns.

• var customItemClicked: Signal4

  Emitted when an item with TreeItem/TreeCellMode/cellModeCustom is clicked with a mouse button.

• var customPopupEdited: Signal8

  Emitted when a cell with the TreeItem/TreeCellMode/cellModeCustom is clicked to be edited.

• var dropModeFlags: Int32

  The drop mode as an OR combination of flags. See DropModeFlags constants. Once dropping is done, reverts to .dropModeDisabled. Setting this during _canDropData(atPosition:data:) is recommended.

• var emptyClicked: Signal3

  Emitted when a mouse button is clicked in the empty space of the tree.

• var enableRecursiveFolding: Bool

  If true, recursive folding is enabled for this Tree. Holding down [kbd]Shift[/kbd] while clicking the fold arrow or using ui_right/ui_left shortcuts collapses or uncollapses the TreeItem and all its descendants.

• var hideFolding: Bool

  If true, the folding arrow is hidden.

• var hideRoot: Bool

  If true, the tree’s root is hidden.

• var itemActivated: SimpleSignal

  Emitted when an item is double-clicked, or selected with a ui_accept input event (e.g. using [kbd]Enter[/kbd] or [kbd]Space[/kbd] on the keyboard).

• var itemCollapsed: Signal5

  Emitted when an item is collapsed by a click on the folding arrow.

• var itemEdited: SimpleSignal

  Emitted when an item is edited.

• var itemIconDoubleClicked: SimpleSignal

  Emitted when an item’s icon is double-clicked. For a signal that emits when any part of the item is double-clicked, see [signal item_activated].

• var itemMouseSelected: Signal2

  Emitted when an item is selected with a mouse button.

• var itemSelected: SimpleSignal

  Emitted when an item is selected.

• var multiSelected: Signal1

  Emitted instead of [signal item_selected] if selectMode is set to .selectMulti.

• var nothingSelected: SimpleSignal

  Emitted when a left mouse button click does not select any item.

• var scrollHorizontalEnabled: Bool

  If true, enables horizontal scrolling.

• var scrollVerticalEnabled: Bool

  If true, enables vertical scrolling.

• var selectMode: Tree.SelectMode

  Allows single or multiple selection. See the SelectMode constants.

• func clear()

  Clears the tree. This removes all items.

• func createItem(parent: TreeItem?, index: Int32) -> TreeItem?

  Creates an item in the tree and adds it as a child of parent, which can be either a valid TreeItem or null.

• func deselectAll()

  Deselects all tree items (rows and columns). In .selectMulti mode also removes selection cursor.

• func editSelected(forceEdit: Bool) -> Bool

  Edits the selected tree item as if it was clicked.

• func ensureCursorIsVisible()

  Makes the currently focused cell visible.

• func getButtonIdAtPosition(Vector2) -> Int32

  Returns the button ID at position, or -1 if no button is there.

• func getColumnAtPosition(Vector2) -> Int32

  Returns the column index at position, or -1 if no item is there.

• func getColumnExpandRatio(column: Int32) -> Int32

  Returns the expand ratio assigned to the column.

• func getColumnTitle(column: Int32) -> String

  Returns the column’s title.

• func getColumnTitleAlignment(column: Int32) -> HorizontalAlignment

  Returns the column title alignment.

• func getColumnTitleDirection(column: Int32) -> Control.TextDirection

  Returns column title base writing direction.

• func getColumnTitleLanguage(column: Int32) -> String

  Returns column title language code.

• func getColumnWidth(column: Int32) -> Int32

  Returns the column’s width in pixels.

• func getCustomPopupRect() -> Rect2

  Returns the rectangle for custom popups. Helper to create custom cell controls that display a popup. See setCellMode(column:mode:).

• func getDropSectionAtPosition(Vector2) -> Int32

  Returns the drop section at position, or -100 if no item is there.

• func getEdited() -> TreeItem?

  Returns the currently edited item. Can be used with [signal item_edited] to get the item that was modified.

• func getEditedColumn() -> Int32

  Returns the column for the currently edited item.

• func getItemAreaRect(item: TreeItem?, column: Int32, buttonIndex: Int32) -> Rect2

  Returns the rectangle area for the specified TreeItem. If column is specified, only get the position and size of that column, otherwise get the rectangle containing all columns. If a button index is specified, the rectangle of that button will be returned.

• func getItemAtPosition(Vector2) -> TreeItem?

  Returns the tree item at the specified position (relative to the tree origin position).

• func getNextSelected(from: TreeItem?) -> TreeItem?

  Returns the next selected TreeItem after the given one, or null if the end is reached.

• func getPressedButton() -> Int32

  Returns the last pressed button’s index.

• func getRoot() -> TreeItem?

  Returns the tree’s root item, or null if the tree is empty.

• func getScroll() -> Vector2

  Returns the current scrolling position.

• func getSelected() -> TreeItem?

  Returns the currently focused item, or null if no item is focused.

• func setColumnClipContent(column: Int32, enable: Bool)

  Allows to enable clipping for column’s content, making the content size ignored.

• func setColumnCustomMinimumWidth(column: Int32, minWidth: Int32)

  Overrides the calculated minimum width of a column. It can be set to 0 to restore the default behavior. Columns that have the “Expand” flag will use their “min_width” in a similar fashion to sizeFlagsStretchRatio.

• func setColumnExpand(column: Int32, expand: Bool)

  If true, the column will have the “Expand” flag of Control. Columns that have the “Expand” flag will use their expand ratio in a similar fashion to sizeFlagsStretchRatio (see setColumnExpandRatio(column:ratio:)).

• func setColumnExpandRatio(column: Int32, ratio: Int32)

  Sets the relative expand ratio for a column. See setColumnExpand(column:expand:).
