ttk Checkbutton select and readonly?

Question

I am using Python 2.7, is there a way to preselect/deselect a Checkbutton in ttk?? As well as making it read-only?

I am trying to display the selected option from a file.

Answer 1

I figured it out myself, the correct syntax would be something like

    self.mon = ttk.Checkbutton(self.dow, text = 'MON')
    self.mon.state(['selected'])
    self.mon.grid(column = 0, row = 0)

I've seen it on a couple of sites, but their syntax are off, this is the correct way to do it!
