Control for a single item inside a [Tree]. Control for a single item inside a [Tree]. May have child [TreeItem]s and be styled as well as contain buttons. You can remove a [TreeItem] by using [method Object.free]. Adds a button with [Texture2D] [code]button[/code] at column [code]column[/code]. The [code]id[/code] is used to identify the button. If not specified, the next available index is used, which may be retrieved by calling [method get_button_count] immediately after this method. Optionally, the button can be [code]disabled[/code] and have a [code]tooltip[/code]. Calls the [code]method[/code] on the actual TreeItem and its children recursively. Pass parameters as a comma separated list. Resets the background color for the given column to default. Resets the color for the given column to default. Removes all OpenType features. Creates an item and adds it as a child. The new item will be inserted as position [code]idx[/code] (the default value [code]-1[/code] means the last position), or it will be the last child if [code]idx[/code] is higher than the child count. Deselects the given column. Removes the button at index [code]button_idx[/code] in column [code]column[/code]. Returns the [Texture2D] of the button at index [code]button_idx[/code] in column [code]column[/code]. Returns the button index if there is a button with id [code]id[/code] in column [code]column[/code], otherwise returns -1. Returns the number of buttons in column [code]column[/code]. May be used to get the most recently added button's index, if no index was specified. Returns the id for the button at index [code]button_idx[/code] in column [code]column[/code]. Returns the tooltip string for the button at index [code]button_idx[/code] in column [code]column[/code]. Returns the column's cell mode. Returns a child item by its index (see [method get_child_count]). This method is often used for iterating all children of an item. Negative indices access the children from the last one. Returns the number of child items. Returns an array of references to the item's children. Returns the custom background color of column [code]column[/code]. Returns the custom color of column [code]column[/code]. Returns custom font used to draw text in the column [code]column[/code]. Returns custom font size used to draw text in the column [code]column[/code]. Returns [code]true[/code] if [code]expand_right[/code] is set. Returns the TreeItem's first child. Returns the given column's icon [Texture2D]. Error if no icon is set. Returns the column's icon's maximum width. Returns the [Color] modulating the column's icon. Returns the icon [Texture2D] region as [Rect2]. Returns the node's order in the tree. For example, if called on the first child item the position is [code]0[/code]. Returns item's text language code. Returns the metadata value that was set for the given column using [method set_metadata]. Returns the next TreeItem in the tree or a null object if there is none. Returns the next visible TreeItem in the tree or a null object if there is none. If [code]wrap[/code] is enabled, the method will wrap around to the first visible element in the tree when called on the last visible element, otherwise it returns [code]null[/code]. Returns OpenType feature [code]tag[/code] of the item's text. Returns the parent TreeItem or a null object if there is none. Returns the previous TreeItem in the tree or a null object if there is none. Returns the previous visible TreeItem in the tree or a null object if there is none. If [code]wrap[/code] is enabled, the method will wrap around to the last visible element in the tree when called on the first visible element, otherwise it returns [code]null[/code]. Returns the value of a [constant CELL_MODE_RANGE] column. Returns a dictionary containing the range parameters for a given column. The keys are "min", "max", "step", and "expr". Gets the suffix string shown after the column value. Returns the given column's text. Returns the given column's text alignment. Returns item's text base writing direction. Returns the given column's tooltip. Returns the [Tree] that owns this TreeItem. Returns [code]true[/code] if the button at index [code]button_idx[/code] for the given column is disabled. Returns [code]true[/code] if the given column is checked. Returns [code]true[/code] if column [code]column[/code] is editable. Returns [code]true[/code] if the given column is indeterminate. Returns [code]true[/code] if column [code]column[/code] is selectable. Returns [code]true[/code] if column [code]column[/code] is selected. Moves this TreeItem right after the given [code]item[/code]. [b]Note:[/b] You can't move to the root or move the root. Moves this TreeItem right before the given [code]item[/code]. [b]Note:[/b] You can't move to the root or move the root. Propagates this item's checked status to its children and parents for the given [code]column[/code]. It is possible to process the items affected by this method call by connecting to [signal Tree.check_propagated_to_item]. The order that the items affected will be processed is as follows: the item invoking this method, children of that item, and finally parents of that item. If [code]emit_signal[/code] is [code]false[/code], then [signal Tree.check_propagated_to_item] will not be emitted. Removes the given child [TreeItem] and all its children from the [Tree]. Note that it doesn't free the item from memory, so it can be reused later. To completely remove a [TreeItem] use [method Object.free]. Selects the column [code]column[/code]. Sets the given column's button [Texture2D] at index [code]button_idx[/code] to [code]button[/code]. If [code]true[/code], disables the button at index [code]button_idx[/code] in column [code]column[/code]. Sets the given column's cell mode to [code]mode[/code]. See [enum TreeCellMode] constants. If [code]true[/code], the column [code]column[/code] is checked. Clears column's indeterminate status. Sets the given column's custom background color and whether to just use it as an outline. Sets the given column's custom color. Sets the given column's custom draw callback to [code]callback[/code] method on [code]object[/code]. The [code]callback[/code] should accept two arguments: the [TreeItem] that is drawn and its position and size as a [Rect2]. Sets custom font used to draw text in the column [code]column[/code]. Sets custom font size used to draw text in the column [code]column[/code]. If [code]true[/code], column [code]column[/code] is editable. If [code]true[/code], column [code]column[/code] is expanded to the right. Sets the given column's icon [Texture2D]. Sets the given column's icon's maximum width. Modulates the given column's icon with [code]modulate[/code]. Sets the given column's icon's texture region. If [code]true[/code], the column [code]column[/code] is marked indeterminate. [b]Note:[/b] If set [code]true[/code] from [code]false[/code], then column is cleared of checked status. Sets language code of item's text used for line-breaking and text shaping algorithms, if left empty current locale is used instead. Sets the metadata value for the given column, which can be retrieved later using [method get_metadata]. This can be used, for example, to store a reference to the original data. Sets OpenType feature [code]tag[/code] for the item's text. Sets the value of a [constant CELL_MODE_RANGE] column. Sets the range of accepted values for a column. The column must be in the [constant CELL_MODE_RANGE] mode. If [code]expr[/code] is [code]true[/code], the edit mode slider will use an exponential scale as with [member Range.exp_edit]. If [code]true[/code], the given column is selectable. Sets a string to be shown after a column's value (for example, a unit abbreviation). Sets the given column's text value. Sets the given column's text alignment. See [enum HorizontalAlignment] for possible values. Sets item's text base writing direction. Sets the given column's tooltip text. If [code]true[/code], the TreeItem is collapsed. The custom minimum height. If [code]true[/code], folding is disabled for this TreeItem. Cell contains a string. Cell contains a checkbox. Cell contains a range. Cell contains an icon.
