The Solution name automatically updates to match the Project name. In the Configure your new project dialog box, enter "HelloPython" for Project name, specify a location, and then select Create. In the Installer, select the Python development workload, and under Installation details, select Python web support. If you don't see the Python web project templates, select Tools > Get Tools and Features to run the Visual Studio Installer. ![]() Choose Web Project from the list, and then select Next: In the Create a new project dialog box, enter "Python web" in the search field at the top. Result of runnning the application in the terminal: $> python test.On the start screen, select Create a new project. value def _process_frame ( self, frame ): """ Do some processing to the frame and return the result frame """ return frame def _runEvent ( self ): """ After setting the best parameters run the full algorithm """ pass if _name_ = '_main_' : from pyforms import start_app start_app ( ComputerVisionAlgorithm ) _formset = def _videoFileSelectionEvent ( self ): """ When the videofile is selected instanciate the video in the player """ self. _process_frame #Define the organization of the Form Controls self. _runEvent #Define the event called before showing the image in the player self. _videoFileSelectionEvent #Define the event that will be called when the run button is processed self. _runbutton = ControlButton ( 'Run' ) #Define the function that will be called when a file is selected self. _player = ControlPlayer ( 'Player' ) self. _blobsize = ControlSlider ( 'Minimum blob size', default = 110, minimum = 100, maximum = 2000 ) self. _threshold = ControlSlider ( 'Threshold', default = 114, minimum = 0, maximum = 255 ) self. _outputfile = ControlText ( 'Results output file' ) self. _videofile = ControlFile ( 'Video' ) self. set_margin ( 10 ) #Definition of the forms fields self. _init_ ( 'Computer vision algorithm example' ) self. The result was the simplicity you can see in the example below: from pyforms.basewidget import BaseWidget from ntrols import ControlFile from ntrols import ControlText from ntrols import ControlSlider from ntrols import ControlPlayer from ntrols import ControlButton class ComputerVisionAlgorithm ( BaseWidget ): def _init_ ( self, * args, ** kwargs ): super (). In the Django Models we just need to define the type of variables and their disposition in the form (in ModelAdmin) to generate a HTML form for data edition.įor the GUIs that I wanted to build in my python scripts, I would like to have the same simplicity, so I could focus on the algorithms and not on GUIs developing. That was the idea.Īfter looking into the several python options for GUI interfaces, PyQt was the one that seemed the best tool for a fast development with the QtDesigner, but after a while developing in Qt, switching between the designer and the python IDE was becoming too costly in terms of time because the interfaces were constantly evolving.īeing a Django developer, I did get inspiration on it for this framework. With GUI applications, users would be able to set the parameters using a GUI interface and visualize the results instantly without the need of restarting the script. To test each set of parameters the script had to be executed. The idea was to transform scripts which had already been developed into GUI applications with a low effort and in a short time.įor example in my computer vision applications in the majority of the times there were variables that had to be set manually in the scripts for each video, to adjust the thresholds, blobs sizes, and other parameters to the environment light conditions. ![]() The development of this library started with the necessity of allowing users with low programming skills to edit parameters from my python scripts. Due to its simplicity it has a low learning curve.Įxamples of applications developed in Pyforms GUIĬheck the documentation at and Rationale behind the framework. ![]()
