Function Details

[hide private]

NoDefaultRoot()

Inhibit setting of default root window.

Call this function to inhibit that the first instance of Tk is used for windows without an explicit parent window.

in_idle()

source code

Returns: boolean: true if this function is run within idle. Tkinter programs that are run in idle should never call Tk.mainloop; so this function should be used to gate all calls to Tk.mainloop.

Warning: This function works by checking sys.stdin. If the user has modified sys.stdin, then it may return incorrect results.

tree_to_treesegment(canvas, t, make_node=<class 'nltk_lite.draw.TextWidget'>, make_leaf=<class 'nltk_lite.draw.TextWidget'>, **attribs)

source code

Convert a Tree into a TreeSegmentWidget.

Parameters:

make_node - A CanvasWidget constructor or a function that creates CanvasWidgets. make_node is used to convert the Tree's nodes into CanvasWidgets. If no constructor is specified, then TextWidget will be used.
make_leaf - A CanvasWidget constructor or a function that creates CanvasWidgets. make_leaf is used to convert the Tree's leafs into CanvasWidgets. If no constructor is specified, then TextWidget will be used.
attribs - Attributes for the canvas widgets that make up the returned TreeSegmentWidget. Any attribute beginning with 'tree_' will be passed to all TreeSegmentWidgets (with the 'tree_' prefix removed. Any attribute beginning with 'node_' will be passed to all nodes. Any attribute beginning with 'leaf_' will be passed to all leaves. And any attribute beginning with 'loc_' will be passed to all text locations (for Trees).
