![]() In order to register a function as an event listener you have to call a function like eventname.do (i.e. The specific callbacks for the widgets will be illustrated later. Such events are a convenient way to define the application behavior.Įach widget has its own callbacks, depending on the type of user interaction it allows. ![]() Widgets expose a set of events that happen during user interaction. height: can be expressed as int (and is interpreted as a pixel) or as str (and you can specify the measuring unit like '10%').width: can be expressed as int (and is interpreted as a pixel) or as str (and you can specify the measuring unit like '10%').If None disables SSL encryptionĪll widgets constructors accept two standards**kwargs that are: ssl_version: authentication version (i.e.password: for a basic HTTP authentication.username: for a basic HTTP authentication.If False, the interface is shown in a browser webpage. standalone: boolean, indicates where to run the application as a standard Desktop application with its own window.start_browser: boolean that defines if the browser should be opened automatically at startup.If zero, the App.idle method is not called. If zero, the update happens at each change. update_interval: GUI update interval in seconds.enable_file_cache: boolean, if True enable resource caching.multiple_instance: boolean, if True multiple clients that connect to your script has different App instances (identified by unique cookie session identifier).You can customize optional parameters in the start call like: start ( MyApp, address = '127.0.0.1', port = 8081, multiple_instance = False, enable_file_cache = True, update_interval = 0.1, start_browser = True ) If it's all OK the GUI will be opened automatically in your browser, otherwise, you have to type in the address bar " ". Outside the main class, start the application by calling the function start and passing the name of the class you declared previously as the parameter: # starts the webserver start ( MyApp ) Label ( "Hello world!", width = 100, height = 30 ) # return of the root widget return lbl _init_ ( * args ) def main ( self ): lbl = gui. class MyApp ( App ): def _init_ ( self, * args ): super ( MyApp, self ). Inside the main function you have to return the root widget. Subclass the App class and declare a main function that will be the entry point of the application. import remi.gui as gui from remi import start, App Import Remi library and some other useful stuff. NO, It is not required, you have to code only in Python.įor sure! Remi is released under the Apache License. Remi needs only a web browser to show your GUI. Kivy, PyQT, and PyGObject all require native code for the host operating system, which means installing or compiling large dependencies. It allows interacting with your Raspberry Pi remotely from your mobile device. Useful on Raspberry Pi for Python script development. You can change the URL address by specific **kwargs at start function call. In order to see the user interface, open your preferred browser and type " ". set_text ( 'Hi!' ) # starts the web server start ( MyApp ) bt ) # returning the root widget return container # listener function def on_button_pressed ( self, widget ): self. on_button_pressed ) # appending a widget to another, the first argument is a string key container. Button ( 'Press me!' ) # setting the listener for the onclick event of the button self. VBox ( width = 120, height = 100 ) self. _init_ ( * args ) def main ( self ): container = gui. When your app starts, it starts a web server that will be accessible on your network.Ī basic application appears like this: import remi.gui as gui from remi import start, App class MyApp ( App ): def _init_ ( self, * args ): super ( MyApp, self ). No HTML is required, Remi automatically translates your Python code into HTML. The entire GUI is rendered in your browser. Remi enables developers to create platform independent GUI with Python. In less than 100 Kbytes of source code, perfect for your diet. Then start the test script (download it from github ): python widgets_overview_app.py Or install directly using pip pip install git+ Look at the Editor subfolder to download your copy.Ī demostrative video from the great REVVEN labsįor the most updated experimental version Download or check out Remi from git and install python setup.py install This allows you to access your interface locally and remotely. Remi is a GUI library for Python applications that gets rendered in web browsers.
