Each ``TreeSegmentWidget`` connects a single "node widget" to a sequence of zero or more "subtree widgets". By default, the bottom of the node is connected to the top of each subtree by a single line. However, if the ``roof`` attribute is set, then a single triangular "roof" will connect the node to all of its children. Attributes: - ``roof``: What sort of connection to draw between the node and its subtrees. If ``roof`` is true, draw a single triangular "roof" over the subtrees. If ``roof`` is false, draw a line between each subtree and the node. Default value is false. - ``xspace``: The amount of horizontal space to leave between subtrees when managing this widget. Default value is 10. - ``yspace``: The amount of space to place between the node and its children when managing this widget. Default value is 15. - ``color``: The color of the lines connecting the node to its subtrees; and of the outline of the triangular roof. Default value is ``'#006060'``. - ``fill``: The fill color for the triangular roof. Default value is ``''`` (no fill). - ``width``: The width of the lines connecting the node to its subtrees; and of the outline of the triangular roof. Default value is 1. - ``orientation``: Determines whether the tree branches downwards or rightwards. Possible values are ``'horizontal'`` and ``'vertical'``. The default value is ``'vertical'`` (i.e., branch downwards). - ``draggable``: whether the widget can be dragged by the user. c ||_||_d|_d|_d|_d|_d|_|Dcgc]}|jdddddc}|_|jddddd |_ |j||D]}|j|d|_ tj||fi|y cc}w) zI :type node: :type subtrees: list(CanvasWidgetI) r F#006060fillhidden)rstateoutlineN)_label _subtrees _horizontal_roof_xspace_yspace_ordered create_line_linescreate_polygon_polygon_add_child_widget _managingr__init__)selfcanvaslabelsubtreesattribscsubtrees c/home/mcse/projects/srt_converter/srt-converter-venv/lib/python3.12/site-packages/nltk/draw/tree.pyr'zTreeSegmentWidget.__init__@s  !

Attributes: - ``node_attr``: Sets the attribute ``attr`` on all of the node widgets for this ``TreeWidget``. - ``node_attr``: Sets the attribute ``attr`` on all of the leaf widgets for this ``TreeWidget``. - ``loc_attr``: Sets the attribute ``attr`` on all of the location widgets for this ``TreeWidget`` (if it was built from a Tree). Note that a location widget is a ``TextWidget``. - ``xspace``: The amount of horizontal space to leave between subtrees when managing this widget. Default value is 10. - ``yspace``: The amount of space to place between the node and its children when managing this widget. Default value is 15. - ``line_color``: The color of the lines connecting each expanded node to its subtrees. - ``roof_color``: The color of the outline of the triangular roof for collapsed trees. - ``roof_fill``: The fill color for the triangular roof for collapsed trees. - ``width`` - ``orientation``: Determines whether the tree branches downwards or rightwards. Possible values are ``'horizontal'`` and ``'vertical'``. The default value is ``'vertical'`` (i.e., branch downwards). - ``shapeable``: whether the subtrees can be independently dragged by the user. THIS property simply sets the ``DRAGGABLE`` property on all of the ``TreeWidget``'s tree segments. - ``draggable``: whether the widget can be dragged by the user. c ||_||_||_i|_i|_ddi|_d|_d|_d|_d|_ d|_ d|_ d|_ d|_ d|_i|_i|_i|_g|_g|_|j)||d |j+||d |_|j/|j,t1j2||fi|y) Nr7z#008000z#008080r5z#c0c0c0Frr6r) _make_node _make_leaf_tree _nodeattribs _leafattribs _locattribs _line_color _line_width _roof_color _roof_fill _shapeablerr _orientationr _keys_expanded_trees_collapsed_trees_nodes_leaves_make_collapsed_trees_make_expanded_tree_treesegr%rr')r(r)rrrr,s r/r'zTreeWidget.__init__&s$# #Y/$$#  &  !
