<h2>Cross Platform Python</h2>
<h3>User Interfaces</h3>
<p>
<small>Big Monthly Meeting 18th September 2014</small>
</p>
</section>
<section>
<h2>Why ??</h2>
<ul>
<li>Command line fear</li>
<li>Distribute code with OS Discs</li>
<li>Curiosity - is this all possible?</li>
</ul>
</section>
<section>
<h2>Goals</h2>
<ol>
<li>Avoid Python Installation</li>
<li>One or small number of files</li>
</ol>
</section>
<section>
<h2>Python GUI Libraries</h2>
<ul>
<li>PyQT</li>
<li>PySide</li>
</ul>
<p>PySide seems preferable due to licensing issues</p>
</section>
<section>
<h2>Deployment</h2>
<p>Would like to deploy to a single executable. No python install necessary</p>
<ul>
<li>py2exe - have had limited success with this</li>
<li>pyinstaller - works better, but still generates a seperate folder on OSX</li>
</ul>
</section>
<section>
<h2>Installation - Not Quite Platform Independent!</h2>
<h3>Windows</h3>
<ul>
<li>Download python: (Use x86 2.7 for now)</li>
<li>Get Pip https://bootstrap.pypa.io/get-pip.py (download script)</li>
<li>c:\python27\python get-pip.py</li>
<li>Add c:\python27\scripts to path</li>
<li>run pip install virtualenv</li>
<li>mkdir pysidetest</li>
<li>virtualenv pysidetest</li>
<li>pysidetest\scripts\activate</li>
<li>pip install PySide</li>
</ul>
</section>
<section>
<h3>Linux</h3>
<ul>
<li>Get Pip https://bootstrap.pypa.io/get-pip.py (download script)</li>
<li>python get-pip.py</li>
<li>run pip install virtualenv</li>
<li>mkdir pysidetest</li>
<li>virtualenv pysidetest</li>
<li>source pysidetest\bin\activate</li>
<li>pip install PySide</li>
</ul>
</section>
<section>
<h3>OSX</h3>
<ul>
<li>Get Pip https://bootstrap.pypa.io/get-pip.py (download script)</li>

<li>virtualenv pysidetest</li>
<li>source pysidetest\bin\activate</li>
<li>Download wheel pyside package</li>
<li>pip install xx.whl</li>
</ul>
