Hello everybody.<br /><br />I am new to this mailing list and to app deployment.<br />I just finished my first app with PyQt5: it's a basic Memory game, made of one python script, a folder of images and a folder of sound effects. The app is working fine (although something might still be missing), and I now would like to deploy it using pyqtdeploy.<br />I am currently working on Ubuntu 16.04, in an python virtual environment (created through conda), where I installed PyQt5 and pyqtdeploy.<br />I'd like to be able to set up a deployment framework so that I would be able to deploy to different platforms (desktop and mobile) the easiest way. I am beginning with Windows (as most of my friends have it).<br />However, as I am completlely new to this kind of stuff, I am finding difficult to follow the tutorial at http://pyqt.sourceforge.net/Docs/pyqtdeploy/tutorial.html.<br />First of all, I downloaded and installed pyqtdeploy to my virtual env succesfully (using pip after activating the conda env) and I am able to run the GUI.<br />There are many things I miss anyway. For example: how do I add my folders to my project (images and sounds)? And, should I be able to produce an executable which I can simply pass to my friends who can try it by simpling double clicking it, or is there much work I will be supposed to do after using pyqtdeploy?<br />Any suggestion would be highly appreciated, as I was super happy to have finally produced my very first app, but now I am kind of lost with regards to the deployment argument.<br />Finally, I attach my script so that everybody can use it, and possibly help me better.<br /><br />
