# Pass any command line argument for Web use If you use our earlier button example but this time import PySimpleGUIWeb and add some web options we see an almost identical presentation however this time it’s in a Web interface.Ĭommand line options can be used to toggle between the different libraries by: import sys web_start_browser – open a Web browser on app start.web_port – port on the micro Web server.web_ip – the IP address to use for the PySimpleGUIWeb micro Web server.The PySimpleGUIWeb window() call has a few more options, such as: To install PySimpleGUIWeb enter: pip install remi PySimpleGUIWeb is an excellent way to create a lightweight standalone Web interface, but it is important to note that it isn’t designed to be a multi-page/multi-user Web environment. The PySimpleGUIWeb library is still under development, so be aware that not all the features in PySimpleGUI are fully supported in the Web version. The feedback text element (line 5) is given a key name of feedback, and this key name is used for updates to show the key press (line 15). The window.read() will return events and values that have been changed (line 14). The PySimplegui sg.window() call displays a window with the title and a layout definition (line 11). Window.Update(event) # show the button in the feedback text Window = sg.Window('My First App', layout) The first row contains a feedback text, then rows 2-5 contains buttons. Graphic elements are placed in separate rows by open and closed square brackets.įor my rover project I used a layout of 5 rows. Graphic presentations are built by creating a layout variable. PySimplegui has a wide range of graphic widgets or elements. To install the default Tktinter version of Pysimplegui enter: pip install pysimplegui
There probably aren’t a lot of cases where you would want to flip between Qt, Wx and Tkinter graphic engines but it is remarkable that the possibility exists.
The versions for Qt,Wx and Web graphics are still in development so some testing may be required if you are hoping for full code compatibility between the different libraries. The main version is for Tkinter based graphics and it is very fully featured. The Python PySimpleGUI project has a number of “ports” or versions. In the this blog I wanted to introduce PySimpleGUI by creating a local GUI/Web interface to control a Raspberry Pi Rover, all in less than 60 lines of code. I feel comfortable doing my own Python Tkinter and Web interfaces, but using common code for both local interfaces and Web apps could be extremely useful for Rasp Pi projects. The Python PySimpleGUI project has two main goals, a simpler method for creating graphical user interfaces (GUIs), and common code for Tkinter, QT, xW and Web graphics.
