Tree

Tree Element - Presents data in a tree-like manner, much like a file/folder browser. Uses the TreeData class to hold the user's data and pass to the element for display.

Tree(
    data = None,
    headings = None,
    visible_column_map = None,
    col_widths = None,
    col0_width = 10,
    def_col_width = 10,
    auto_size_columns = True,
    max_col_width = 20,
    select_mode = None,
    show_expanded = False,
    change_submits = False,
    font = None,
    justification = "right",
    text_color = None,
    background_color = None,
    num_rows = None,
    pad = None,
    key = None,
    tooltip = None
)

auto_size_columns	bool	True	if True, the size of a column is determined using the contents of the column
background_color	str	None	color of background

col0_width	int	10	Size of Column 0 which is where the row numbers will be optionally shown
col_widths	List[int]	None	List of column widths so that individual column widths can be controlled
data	TreeData	None	The data represented using a PySimpleGUI provided TreeData class
def_col_width	int	10	default column width
font	(str or (str, int[, str]) or None)	None	specifies the font family, size, etc. Tuple or Single string format 'name size styles'. Styles: italic * roman bold normal underline overstrike
headings	List[str]	None	List of individual headings for each column
justification	str	right	'left', 'right', 'center' are valid choices

num_rows	int	None	The number of rows of the table to display at a time
pad	(int, int or (int, int),(int,int) or int,(int,int)) or ((int, int),int)	None	Amount of padding to put around element in pixels (left/right, top/bottom) or ((left, right), (top, bottom)) or an int. If an int, then it's converted into a tuple (int, int)
select_mode	enum	None	Use same values as found on Table Element. Valid values include: TABLE_SELECT_MODE_NONE TABLE_SELECT_MODE_BROWSE TABLE_SELECT_MODE_EXTENDED
show_expanded	bool	False	if True then the tree will be initially shown with all nodes completely expanded
text_color	str	None	color of the text
