QPython WebApp Principle¶
About¶
QPython supports WebApp, the goal is to enable all WEB developers to the fastest development of mobile applications.
Advantages¶
There are lots of mobile WebApp solutions, like cordova, phonegap etc, and compared to them, QPython’s WebApp has the following advantages.
QPython is a powerful Python engine that can handle many logical jobs, effectively reducing data transfer time and enhancing your app’s user experience
QPython supports massive Python libraries, you could import them in your project, so that you could save much develop time.
It is very convenient for development with QPython, you can complete your development just in palm. And you could develop from PC then transfer to your mobile to run
How does WebApp work in QPython¶
QPython WebApp contains the following components: WebApp service and Webview. The WebApp service runs in the background and is responsible for responding to user’s input. WebView is a front component, which shows the user interface and and is responsible for responding to render user interactions, such as scrolling, click the button and so on.
1 When you run a WebApp program from QPython, QPython launch the WebApp service in the background, at the same time, QPython will start a webview which loads the entry link declared in the program header in the front.
#qpy:webapp:<webapp-title>
#qpy://<webapp-address>:<webapp-port>/<webapp-path>
2 Then the user can start to interact with the applicaton with the web mode. So the developer could write the logic code with the web development way.
3 When the user exit by clicking the left arrow, the application will request the http://<webapp-address><:webapp-port>/__exit to exit the application The developer could rewrite the __exit function to defines the exit behaviors.
