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 s||_||_d|_d|_d|_d|_d|_‡fdd„|Dƒ|_ˆjddddd d |_ |  |¡|D]}|  |¡q1d|_ t j |ˆfi|¤Žd S) zI :type node: :type subtrees: list(CanvasWidgetI) ré éFc s g|] }ˆjdddddd‘qS)rú#006060©Úfill)Ú create_line)Ú.0Úc©Úcanvas©ú=/var/www/auris/lib/python3.10/site-packages/nltk/draw/tree.pyÚ Pó z.TreeSegmentWidget.__init__..ÚÚhiddenr)rÚstateÚoutlineN)Ú_labelÚ _subtreesÚ _horizontalÚ_roofÚ_xspaceÚ_yspaceÚ_orderedÚ_linesZcreate_polygonÚ_polygonÚ_add_child_widgetÚ _managingrÚ__init__)ÚselfrÚlabelÚsubtreesÚattribsÚsubtreerrrr+@s  ÿ  zTreeSegmentWidget.__init__cCsÌ| ¡}|dkr<||_|jr%|jD] }|j|ddq|j|jdddS|jD] }|j|ddq(|j|jdddS|dkrV|dkrId|_dS|dkrRd |_dStd ƒ‚|d krq|jD] }|j||d q]|j|j|d dSt|tƒrŽ|d d krŽ|jt |dƒ}|j||d dS|dkrœ|j|j|d dS|dkr¹| |j||i¡|jD] }| |||i¡q¬dS|dvrÔ|dkrÅ||_ n|dkrÌ||_ |  |j ¡dS|dkrÝ||_dSt |||¡dS)NÚroofr)rÚnormalÚ orientationÚ horizontaléÚverticalrz*orientation must be horizontal or verticalÚcolorr)rrÚwidth)ÚxspaceÚyspacer9r:Úordered)rr#r'Z itemconfigr(r"Ú ValueErrorÚ isinstanceÚtupleÚintr$r%Úupdater r&rÚ __setitem__)r,ÚattrÚvaluerÚlrrrrA_sN      ÿ zTreeSegmentWidget.__setitem__cCsÆ|dkr|jS|dkr| ¡ |j|¡S|dkr!| ¡ |jd¡St|tƒr=|ddkr=|jt|dƒ}| ¡ |d¡S|dkrD|jS|d krK|j S|d krV|j rTd Sd S|d kr]|j St   ||¡S)Nr1r8r7rrr5rr9r:r3r4r6r;)r#rZitemcgetr(r=r>r'r?r$r%r"r&rÚ __getitem__)r,rBrDrrrrE‹s( zTreeSegmentWidget.__getitem__cCs|jS©N)r ©r,rrrr-£szTreeSegmentWidget.labelcCs|jdd…SrF)r!rGrrrr.¦szTreeSegmentWidget.subtreescCs,| |j¡| |¡||_| |j¡dS)z2 Set the node label to ``label``.

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. cKs¾||_||_||_i|_i|_ddi|_d|_d|_d|_d|_ d|_ d|_ d|_ d|_ d|_i|_i|_i|_g|_g|_| ||d ¡| ||d ¡|_| |j¡tj||fi|¤ŽdS) Nr7z#008000z#008080r5z#c0c0c0Frr6r)Ú _make_nodeÚ _make_leafZ_treeÚ _nodeattribsÚ _leafattribsÚ _locattribsÚ _line_colorÚ _line_widthÚ _roof_colorÚ _roof_fillÚ _shapeabler$r%Ú _orientationr&Ú_keysÚ_expanded_treesÚ_collapsed_treesÚ_nodesÚ_leavesÚ_make_collapsed_treesÚ_make_expanded_treeÚ_treesegr)rr+)r,rr‹rˆr‡r/rrrr+&s0  zTreeWidget.__init__cGó |j|S©aF Return the ``TreeSegmentWidget`` for the specified subtree. :param path_to_tree: A list of indices i1, i2, ..., in, where the desired widget is the widget corresponding to ``tree.children()[i1].children()[i2]....children()[in]``.
