A windows form application framework using python

Hey I’m looking for a way to develop a windows form application like the one in visual studio, that using c# and has a visual designer option but that using python instead. I know that I can use tkinter to create a WFA but I really need that designer option. Any suggestions?

Thanks for your replies but does PyQt work with Visual Studio 2019 or do I have to use the QT Designer?

1. pip install it : pip install PyQt5-tools
2. Then navigate to Lib/site-packages/pyqt5_tools open the designer, design what you have in mind and save it.
3. Now run Scripts/pyuic5 like this :

 scripts/pyuic5 -x path to your sth.ui -o your_design.py 

(where sth.ui is the file saved in PyQt designer. The command in step 3 converts the sth.ui file to a .py file.) (you need to be in the root of your python distribution) there you have your window, etc in python and now you can write the logic for it.

You may also find this video clip useful.

You can try PyQT. It has a visual Builder named QT Designer and you can generate a python file from it.

PyQt5 and PyQt5 Designer are what you need. I made one project https://github.com/XtremeGood/Mailer .

But that’s not enough. To make it an executable you will need to know how to use pyinstaller and then use NSIS scripting or https://nsis.sourceforge.io/NSIS_Quick_Setup_Script_Generator to package it to create a windows executable file.

Python windows forms application

I want to do some applications with python, but I haven’t found any way of getting a tool-box of buttons, check box, etc. Can some explain me please how can I do that with: 1. Pycharm. 2. If it is problem with Pycharm, visual studio community is also okay. Thanks, Ayal

This is what I have found: There is a designer from QT, to build a ui file. There is a tool for translating the ui into python. Then you can edit the logic, with any python tool. You only need PyQt the current version is PyQt5.

IronPython Windows forms, passing variables in python

I’m new to IronPython and trying to create a simple application with Windows Forms that converts a fixed fielded file to a delimited file.

I’ve created a form with three buttons.

The first is to select the file to be converted. The second is to select a file with a the layout of the first file. The third is a ‘submit’ button to send the file names of the two files above to the python function that will convert the file.

The first two buttons work fine. My problem is passing the file names to the ‘button_submitPressed’ function. I tried to make FILENAME and LAYOUT global variables (I’ve tried it inside and outside of the ‘HelloWorldForm’ class but neither are working).

What do I have to do to pass variables that I collect in button events to another function?

When I run this, when I click on the submit button (after clicking the first two and selecting the filename and layout) I get the error:

IronPython.Runtime.UnboundNameException: global name 'FILENAME' is not defined 

class HelloWorldForm(Form): FILENAME = '' LAYOUT = '' def __init__(self): self.Text = 'ff2delim' self.label = Label() self.label.Text = "Convert fixed legnth file to delimited" self.label.Location = Point(50, 50) self.label.Height = 30 self.label.Width = 200 self.count = 0 button = Button() button.Text = "File name" button.Location = Point(50, 100) button.Click += self.buttonPressed button2 = Button() button2.Text = "Layout" button2.Location = Point(50, 130) button2.Click += self.button2Pressed button_submit = Button() button_submit.Text = "Convert" button_submit.Location = Point(50, 190) button_submit.Click += self.button_submitPressed self.Controls.Add(self.label) self.Controls.Add(button) self.Controls.Add(button2) self.Controls.Add(button_submit) def buttonPressed(self, sender, args): dialogf = OpenFileDialog() if dialogf.ShowDialog() == DialogResult.OK: FILENAME = dialogf.FileName print "FILENAME: " + FILENAME self.label_filename = Label() self.label_filename.Text = FILENAME self.label_filename.Location = Point(140, 105) self.label_filename.Height = 30 self.label_filename.Width = 200 self.Controls.Add(self.label_filename) else: print "No file selected" def button2Pressed(self, sender, args): dialogl = OpenFileDialog() if dialogl.ShowDialog() == DialogResult.OK: LAYOUT = dialogl.FileName print "LAYOUT: " + LAYOUT self.label_layout = Label() self.label_layout.Text = LAYOUT self.label_layout.Location = Point(140, 135) self.label_layout.Height = 30 self.label_layout.Width = 200 self.Controls.Add(self.label_layout) else: print "No file selected" def button_submitPressed(self, sender, args): convert(FILENAME,LAYOUT) 

I was able to get this working by putting in a global variable in the first two button handlers.

def buttonPressed(self, sender, args): global FILENAME dialogf = OpenFileDialog() if dialogf.ShowDialog() == DialogResult.OK: FILENAME = dialogf.FileName print "FILENAME: ",FILENAME . def button2Pressed(self, sender, args): global LAYOUT dialogl = OpenFileDialog() if dialogl.ShowDialog() == DialogResult.OK: LAYOUT = dialogl.FileName print "LAYOUT: " + dialogl.FileName . 

Then in the third button handler:

def button_submitPressed(self, sender, args): print "FILENAME SUB: ",FILENAME print "LAYOUT SUB: ",LAYOUT convert(FILENAME,LAYOUT) 

The third button handler then successfully calls the convert function.

For future readers, OP’s code would have worked if he accessed his class level constants through the class:

def button_submitPressed(self, sender, args): convert(self.FILENAME,self.LAYOUT)

Overview

When developing GUI applications in python for Windows, standard python library choices are limiting and do not provide the same quality of experience as applications developed with Visual Studio, especially when bundled together with 3rd party WinForms or WPF such as DevExpress, As a result, python developers typically turn to Visual Studio and IronPython when developing for Windows. However, there is an alternative.

Python.Net

Python.Net( http://pythonnet.sourceforge.net/ ), built by Brian Lloyd is a lightweight, yet powerful package that enables CPython to load and interact with CLR based packages/libraries. It is fairly robust, performant and supports most CLR constructs and data types. In the simplest form, the following coding snippet demonstrates power and capability of Python.Net. You can download Python.Net here( http://www.lfd.uci.edu/~gohlke/pythonlibs/ )

Building a WinForms application

With python.net configured, we can now build a basic Winforms application running from CPython. First let’s use Visual Studio to build a basic form and compile it into an clr assembly. For below example, I created a form called SimpleForm in SimpleForm namespace and packaged it inside SimpleForm.dll. The form has text field called textBox and a button called btn_sayit . The following python code can then be used launch the form and handle click event on btn_sayit to print contents of textBox to the console.

To simplify the python interface, I’ve set Modifier as public on textBox and btn_sayit widgets, this is not strictly necessary as you can also get access to them using form.Controls collection, but it makes for simpler and cleaner interface

Defining a UI Framework

To keep GUI Development more pythonic and UnitTestable, we can formally define Model View and Presenter python classes which would decouple WinForms code from the application and create a classical UI segregation of responsibilities.

With above structure in place, all business logic is performed in the model that is completely independent of the view and, therefore, can be unit tested and developed separately from WinForms components. Furthermore, presenter is injected with a python object wrapping a WinForms view which can be easily substituted with a stub or a mock for unit testing purposes.

Above pattern is an extension of a Passive View Pattern described by Martin Fowler http://martinfowler.com/eaaDev/PassiveScreen.html
