Why can't I do any Input to DirectGUI or tkinter?

Scripting Issues
1

How can I recieve the inputs from the GUI tools(tkinter or DirectGUI)?

2

use named parameters to set a callback function (or a lambda)

          frame.addItem(DirectCheckButton(
                text="sample button",
                text_align=TextNode.A_left,
                indicatorValue=1,
                command=lambda k: print("value is now " + k)
            ))
