This script <span class="hiddenGrammarError" pre="script ">was written</span> by <span class="hiddenSpellError" pre="by ">Sunjay</span> <span class="hiddenSpellError" pre="Sunjay ">Varma</span> - www.sunjay-varma.com
This script has two main classes:
Tab - Basic tab used by <span class="hiddenSpellError" pre="by "><span class="mceItemHidden" spellcheck="false"><span class="hiddenSpellError" pre="">TabBar</span></span></span> <span class="hiddenSpellError" pre="TabBar ">for</span> main functionality
<span class="hiddenSpellError" pre=""><span class="mceItemHidden" spellcheck="false"><span class="hiddenSpellError" pre="">TabBar</span></span></span> - The tab bar that <span class="hiddenGrammarError" pre="that ">is placed</span> above tab bodies (Tabs)
It uses a pretty basic structure:
root
--><span class="hiddenSpellError" pre="">TabBar</span>(root, init_name) (For switching tabs)
-->Tab (Place holder for content)
\t-->content (content of the tab; parent=Tab)
-->Tab (Place holder for content)
\t-->content (content of the tab; parent=Tab)
-->Tab (Place holder for content)
\t-->content (content of the tab; parent=Tab)
etc.
