Change font size of notebook tabs in ruby tk
<p>Using ruby (1.9.1) with tk, I am creating a simple notebook/tab page.</p>

<p>I want to change the font of the tabs and haven't found a way to do that yet, though I know it can be done in other languages.</p>

<p>Here's some simple base code:</p>

<pre><code>root = TkRoot.new
root.title = "Window"
myFont = TkFont.new("family" =&gt; 'Helvetica', "size" =&gt; 20)
tabs = TkNotebook.new(root) { height 100 }.pack
tab1 = TkFrame.new(tabs)
tab2 = TkFrame.new(tabs)
tabs.add tab1, text: "Tab 1"
tabs.add tab2, text: "Tab 2"

Tk.mainloop
</code></pre>

<p>Where can I set the tabs to use 'myFont'?</p>
