class tkinter.ttk.Treeview

bbox(item, column=None)

Returns the bounding box (relative to the treeview widget’s window) of the specified item in the form (x, y, width, height).

get_children(item=None)

Returns the list of children belonging to item.

If item is not specified, returns root children.

set_children(item, *newchildren)

Replaces item‘s child with newchildren.

Children present in item that are not present in newchildren are detached from the tree. No items in newchildren may be an ancestor of item. Note that not specifying newchildren results in detaching item‘s children.

column(column, option=None, **kw)

Query or modify the options for the specified column.

If kw is not given, returns a dict of the column option values. If option is specified then the value for that option is returned. Otherwise, sets the options to the corresponding values.

The valid options/values are:

• id

  Returns the column name. This is a read-only option.

• anchor: One of the standard Tk anchor values.

  Specifies how the text in this column should be aligned with respect to the cell.

• minwidth: width

  The minimum width of the column in pixels. The treeview widget will not make the column any smaller than specified by this option when the widget is resized or the user drags a column.

• stretch: True/False

  Specifies whether the column’s width should be adjusted when the widget is resized.

• width: width

  The width of the column in pixels.

To configure the tree column, call this with column = “#0”

delete(*items)

Delete all specified items and all their descendants.

The root item may not be deleted.

detach(*items)

Unlinks all of the specified items from the tree.

The items and all of their descendants are still present, and may be reinserted at another point in the tree, but will not be displayed.

The root item may not be detached.

exists(item)

Returns True if the specified item is present in the tree.

focus(item=None)

If item is specified, sets the focus item to item. Otherwise, returns the current focus item, or ‘’ if there is none.

heading(column, option=None, **kw)

Query or modify the heading options for the specified column.

If kw is not given, returns a dict of the heading option values. If option is specified then the value for that option is returned. Otherwise, sets the options to the corresponding values.

The valid options/values are:

• text: text

  The text to display in the column heading.

• image: imageName

  Specifies an image to display to the right of the column heading.

• anchor: anchor

  Specifies how the heading text should be aligned. One of the standard Tk anchor values.

• command: callback

  A callback to be invoked when the heading label is pressed.

To configure the tree column heading, call this with column = “#0”.

identify(component, x, y)

Returns a description of the specified component under the point given by x and y, or the empty string if no such component is present at that position.

identify_row(y)

Returns the item ID of the item at position y.

identify_column(x)

Returns the data column identifier of the cell at position x.

The tree column has ID #0.

identify_region(x, y)

Returns one of:

region	meaning
heading	Tree heading area.
separator	Space between two columns headings.
tree	The tree area.
cell	A data cell.

Availability: Tk 8.6.

identify_element(x, y)

Returns the element at position x, y.

Availability: Tk 8.6.

index(item)

Returns the integer index of item within its parent’s list of children.

insert(parent, index, iid=None, **kw)

Creates a new item and returns the item identifier of the newly created item.

parent is the item ID of the parent item, or the empty string to create a new top-level item. index is an integer, or the value “end”, specifying where in the list of parent’s children to insert the new item. If index is less than or equal to zero, the new node is inserted at the beginning; if index is greater than or equal to the current number of children, it is inserted at the end. If iid is specified, it is used as the item identifier; iid must not already exist in the tree. Otherwise, a new unique identifier is generated.

See Item Options for the list of available points.

item(item, option=None, **kw)

Query or modify the options for the specified item.

If no options are given, a dict with options/values for the item is returned. If option is specified then the value for that option is returned. Otherwise, sets the options to the corresponding values as given by kw.

move(item, parent, index)

It is illegal to move an item under one of its descendants. If index is less than or equal to zero, item is moved to the beginning; if greater than or equal to the number of children, it is moved to the end. If item was detached it is reattached.

next(item)

Remove items from the selection.

selection_toggle(items)

set(item, column=None, value=None)

With one argument, returns a dictionary of column/value pairs for the specified item. With two arguments, returns the current value of the specified column. With three arguments, sets the value of given column in given item to the specified value.

tag_bind(tagname, sequence=None, callback=None)
