title: Tkinter TTK Button Bold Font
body: <p>First of all, thank you for taking the time to look at and read my question.
  What I'm trying to do is to make the font of a TTK button bold. It is very easy to do with a normal Tkinter button, but I'm having a little trouble with a TTK one.</p>
  
  <p>Here's what I have for a normal Tkinter button:</p>
  
  <pre><code>boldFont = Font (size = 10, weight = "bold")
  boldButton = Button (formatBar, text = "B", width = 2, font = boldFont)
  boldButton.pack (side = LEFT, padx = 1, pady = 1)
  </code></pre>
  
  <p>And that achieves what I would like, but when I try the same thing with a TTK button (using a TTK style instead of a font), it doesn't make the text bold.</p>
  
  <p>TTK button:</p>
  
  <pre><code>boldStyle = ttk.Style ()
  boldStyle.configure ("Bold.TButton", size = 10, weight = "bold")
  boldButton = ttk.Button (formatBar, text = "B", width = 2, style = "Bold.TButton")
  boldButton.pack (side = LEFT, padx = 1, pady = 1)
  </code></pre>
  
  <p>I'm probably just being a little stupid, but I can't find any way to fix this. I've done a little research and tried converting some TCL code, but none of it works.</p>
