# PySimpleGUI-HowDoI
|
||||
|
||||
## Introduction
|
||||
This package contains a GUI front-end to the AMAZING tool, HowDoI. You can ask this tool any programming question and it will tap into the enormous database of programming questions and answers, StackOverflow.
|
||||
|
||||
This program takes you question and returns CODE as a response.
|
||||
|
||||
The way it works is that it searches StackOverflow, gets the results and then finds the highest voted answer. From that answer it takes the code it finds and that is what is returned to you. It works shockingly well.
|
||||
|
||||
To learn more about HowDoI, visit their GitHub site:
|
||||
https://github.com/gleitz/howdoi
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
Check out this example. This was not rehearsed. While typing this readme, an example was needed and a random question, that I've never asked before, was posed. Once again this program delivered a great answer.
|
||||
|
||||
You can copy and paste the solution right into your code if you wish.
|
||||
|
||||
## Installing
|
||||
|
||||
When you install PySimpleGUI-HowDoI, it will install the other components that it requires. To install, on windows, type this into a command prompt:
|
||||
|
||||
pip install pysimplegui-howdoi
|
||||
|
||||
|
||||
## Running the GUI Program
|
||||
|
||||
Afer your Pip install completes you can run the program. Do run it, type this into your command prompt:
|
||||
|
||||
python -m pysimplegui-howdoi.pysimplegui-howdoi
|
||||
|
||||
Once running you simply type in your question and press enter or click the "SEND" button. If you want to ask a question again, you can use the arrow keys or your mouse wheel to access the history of questions you've previously asked.
|
||||
|
||||
Ask ANY question you want for ANY programming language. I recommend starting the question with the programming language.
|
||||
|
||||
|
||||
## PySimpleGUI Project
|
||||
|
||||
This program was built as a sample application of the PySimpleGUI GUI Framework. It quickly became a tool I was unable to live without. I've been trying for some time to bring it to life for others to try.
|
||||
|
||||
## Windows Only?
|
||||
|
||||
This has only been tested using Windows. I have not gotten it to work under Linux. The linkage between the program and the howdoI package was messed up on Linux. If you're able to get a Linux version running, please let me know at info@PySimpleGUI.org

|

You can use the exact same code that you are running on the older, tkinter, version of PySimpleGUI.
|
||||
|

PySimpleGUIQt uses **PySide2** for access to Qt.

PySimpleGUIQt uses **PySide2** OR **PyQt5** for access to Qt.

### Differences between PySimpleGUI and PySimpleGUIQt
|
||||
## Porting your PySimpleGUI code to PySimpleGUIQt
|
||||
|
||||
|
||||
To "port" your code from the tkinter implementation. Follow these steps:
|
||||
|
||||
1. Change `import PySimpleGUI` to `PySimpleGUIQt`
|
||||
|
||||
That's it! OK, maybe I should have said step instead of steps.
|
||||
|
||||
|
||||
## Differences between PySimpleGUI and PySimpleGUIQt
|
||||
|
||||
#### Sizes
|
||||
IMPORTANT NOTE if you are porting from tkinter to Qt - You will need to make one important change to your code.... **You must change your size parameters to be in PIXELS instead of CHARACTERS**.
|
||||
|
||||
While you can use "Character-based" sizes like you did in tkinter, it's best to use pixel based sizes as that is what Qt uses. PySimpleGUIQt does some very rough / basic conversions from the character sizes to pixel sizes. It's enough that your elements will at least be visible. But the conversion is likely to not be ideal.
|
||||
|
||||
#### Fonts
|
||||
|
||||
Fonts should be in the format (font family, size). The original PySimpleGUI also allowed a font string 'Family Size' but that option is not available (yet) in the Qt version. I'll add it though so the code ports straight over.
|
||||
|
||||
Fonts should be in the format (font family, size). You can use the older string based too, but it will not work with setting like bold and italics. PySimpleGUIQt converts from the string 'Courier 20' to the tuple ('Courier', 20) for you.
|
||||
|
||||
|
||||
### Installing PySimpleGUIQt for Python 3
|
||||
|
||||
pip install --upgrade PySimpleGUIQt
|

On some systems you need to run pip3.
|
||||
On Linux systems you need to run pip3.

||||
pip3 install --upgrade PySimpleGUIQt

### Installing PySide2 for Python 3
|
||||
### Installing PySide2 or PyQt5 for Python 3
|
||||
|
||||
It is recommended that you use PySide2, however, if that cannot be found, then PyQt5 will be attempted. To install either of these:
|
||||
|
||||
```pip install PySide2```
|
||||
|
||||
or
|
||||
|
||||
|

```pip install PyQt5```
