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]. [b]Note:[/b] The ID values used for buttons are limited to 32 bits, not full 64 bits of [int]. This has a range of [code]-2^32[/code] to [code]2^32 - 1[/code], i.e. [code]-2147483648[/code] to [code]2147483647[/code]. Adds a button with [Texture] [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 before this method. Optionally, the button can be [code]disabled[/code] and have a [code]tooltip[/code]. Resets the background color for the given column to default. Resets the color for the given column to default.

Returns the column's icon's maximum width. Returns the [Color] modulating the column's icon. Returns the icon [Texture] region as [Rect2]. Returns the metadata value that was set for the given column using [method set_metadata]. Returns the next sibling TreeItem in the tree or a null object if there is none. Returns the next visible sibling 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 the parent TreeItem or a null object if there is none. Returns the previous sibling TreeItem in the tree or a null object if there is none. Returns the previous visible sibling 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 the given column's tooltip. 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 column [code]column[/code] is selectable. Returns [code]true[/code] if column [code]column[/code] is selected. Moves this TreeItem to the bottom in the [Tree] hierarchy. Moves this TreeItem to the top in the [Tree] hierarchy. 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 [Texture] 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. Sets the given column's custom background color and whether to just use it as an outline. Sets the given column's custom color. 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 [Texture].

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 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 [code]set_text_align()[/code]. Center text. See [code]set_text_align()[/code]. Align text to the right. See [code]set_text_align()[/code].
