### PySimpleGUI PEP8 Method Renaming and Signature

Source: https://freesimplegui.readthedocs.io/en/latest/index

Explains the conversion of PySimpleGUI's CamelCase methods to PEP8 snake_case, detailing the renaming rule and providing an example of a method signature with parameters. This change aims to align PySimpleGUI with Python's PEP8 style guide.

```APIDOC
PySimpleGUI PEP8 Bindings:

Purpose:
To provide PEP8 compliant snake_case equivalents for PySimpleGUI's existing CamelCase methods and functions, aligning with Python's standard naming conventions.

Renaming Convention:
To convert a CamelCase method/function name to snake_case, insert an underscore `_` before each uppercase letter. If there are no uppercase letters, only the first letter is changed to lowercase.

Example Conversion:
`Window.FindElement` becomes `Window.find_element`

Method Signature Example:
`Read(self, timeout=None, timeout_key='__TIMEOUT__', close=False)`
  - Parameters:
    - `self`: The instance of the Window object.
    - `timeout`: Optional. The number of seconds to wait for an event. Defaults to None (wait indefinitely).
    - `timeout_key`: Optional. The key to return when a timeout occurs. Defaults to '__TIMEOUT__'.
    - `close`: Optional. If True, the window is closed after reading. Defaults to False.
  - Returns:
    A tuple containing the event and the values dictionary.

Note:
CamelCase names are currently supported but will be removed in future releases. A utility is planned to assist developers with the conversion.
```

### Create and Update Window with Progress Meter

Source: https://freesimplegui.readthedocs.io/en/latest/cookbook

Demonstrates creating a basic window with a progress meter and updating it within a loop. It includes handling user interaction like cancellation and window closure. Assumes 'layout' and 'sg' are defined.

```python
# create the Window
window = sg.Window('Custom Progress Meter', layout)
# loop that would normally do something useful
for i in range(1000):
    # check to see if the cancel button was clicked and exit loop if clicked
    event, values = window.read(timeout=10)
    if event == 'Cancel' or event == sg.WIN_CLOSED:
        break
        # update bar with loop value +1 so that bar eventually reaches the maximum
    window['-PROG-'].update(i+1)
# done with loop... need to destroy the window as it's still open
window.close()
```

### PySimpleGUI Tooltip and Size Parameters

Source: https://freesimplegui.readthedocs.io/en/latest/index

Explains the 'tooltip' and 'size' parameters in detail, including advanced usage for tooltips and various sizing methods for elements. Covers pixel-based sizing, auto-sizing, and conversion logic for different GUI ports.

```APIDOC
Tooltip and Size Parameters:

Tooltip:
  - Purpose: Provides descriptive text when a user hovers over an element.
  - Customization: The background color of tooltips can be changed using the `TOOLTIP_BACKGROUND_COLOR` constant (default: "#ffffe0").

Size:
  - Character-based: For elements like Text and Button, `size=(width, height)` is measured in characters.
  - Auto-size: Text and Button elements have auto-size enabled by default, sizing to their content. This can be turned off to enforce uniform sizes.
  - Integer input: `size=N` is equivalent to `size=(N, 1)`.
  - Pixel-based (Non-Tkinter Ports):
    - `size_px=(width_px, height_px)`: Directly sets size in pixels.
    - Implicit Pixel Conversion: If `size[0]` exceeds `DEFAULT_PIXEL_TO_CHARS_CUTOFF` (default 20), it's treated as pixels. Some elements like Multline have a higher cutoff (100).
  - Pixel to Character Scaling:
    - `DEFAULT_PIXELS_TO_CHARS_SCALING = (10, 26)`: Used for converting pixel dimensions to character-based sizes (width * 10, height * 26).
```

### File/Folder Selection GUI in FreeSimpleGUI

Source: https://freesimplegui.readthedocs.io/en/latest/index

Illustrates creating a GUI window for selecting source folders and files using browse buttons. It demonstrates how to define a layout with input fields, browse buttons, and action buttons like Submit and Cancel.

```python
import FreeSimpleGUI as sg

sg.theme('Dark Blue 3')  # please make your windows colorful

layout = [[sg.Text('Rename files or folders')],
      [sg.Text('Source for Folders', size=(15, 1)), sg.InputText(), sg.FolderBrowse()],
      [sg.Text('Source for Files ', size=(15, 1)), sg.InputText(), sg.FileBrowse()],
      [sg.Submit(), sg.Cancel()]]

window = sg.Window('Rename Files or Folders', layout)

event, values = window.read()
window.close()
folder_path, file_path = values[0], values[1]       # get the data from the values dictionary
print(folder_path, file_path)
```

--------------------------------

### Finding PySimpleGUI Installation Path

Source: https://freesimplegui.readthedocs.io/en/latest/index

To determine the exact location of your PySimpleGUI installation, you can import the library in the Python REPL or within your script and print the module object. This is crucial for debugging and ensuring you are using the intended version.

```python
# In Python REPL
>>> import FreeSimpleGUI as sg
>>> sg
```

```python
# Within your Python script
import FreeSimpleGUI as sg

print(sg)
print(sg.version)
```

--------------------------------

### Get Filename with FileBrowse

Source: https://freesimplegui.readthedocs.io/en/latest/index

Demonstrates a basic FreeSimpleGUI window to get a filename from the user. It includes a text input field and a FileBrowse button, along with OK and Cancel buttons. The selected filename is then displayed in a popup.

```python
import FreeSimpleGUI as sg

sg.theme('Dark Blue 3')  # please make your windows colorful

layout = [[sg.Text('Filename')],
            [sg.Input(), sg.FileBrowse()],
            [sg.OK(), sg.Cancel()] ]

window = sg.Window('Get filename example', layout)
event, values = window.read()
window.close()

sg.Popup(event, values[0])

```

--------------------------------

### Popup Input Functions

Source: https://freesimplegui.readthedocs.io/en/latest/index

Provides functions for getting single-item input from the user via popups. These include getting text, filenames, and folder names. Use these for simple input tasks before resorting to custom window creation.

```APIDOC
Popup Input Functions:

  popup_get_text: Get a single line of text from the user.
  popup_get_file: Get a filename from the user.
  popup_get_folder: Get a folder name from the user.

These functions offer customizable settings for creating specific input dialogs. If the available parameters are insufficient, consider creating a custom window.
```

### Chat Window Example with Output Element in FreeSimpleGUI

Source: https://freesimplegui.readthedocs.io/en/latest/index

A complete example of a chat window using the Output element to display received messages. Data is displayed by simply printing it, which is then routed to the Output element. This pattern is useful for real-time feedback within an application.

```python
import FreeSimpleGUI as sg

def ChatBot():
    layout = [[(sg.Text('This is where standard out is being routed', size=[40, 1]))],
              [sg.Output(size=(80, 20))],
              [sg.Multiline(size=(70, 5), enter_submits=True), 
               sg.Button('SEND', button_color=(sg.YELLOWS[0], sg.BLUES[0])),
               sg.Button('EXIT', button_color=(sg.YELLOWS[0], sg.GREENS[0]))]]

    window = sg.Window('Chat Window', layout, default_element_size=(30, 2))

    # ---===--- Loop taking in user input and using it to query HowDoI web oracle --- #
    while True:
        event, value = window.read()
        if event == 'SEND':
            print(value)
        else:
            break
    window.close()

### FreeSimpleGUI Frame Element Layout Example

Source: https://freesimplegui.readthedocs.io/en/latest/index

Illustrates the usage of the `sg.Frame` element to create a labelled section within a FreeSimpleGUI window. This example shows a window containing a frame with text and checkboxes, alongside submit and cancel buttons, demonstrating how frames group related elements.

```python
frame_layout = [
                  [sg.T('Text inside of a frame')],
                  [sg.CB('Check 1'), sg.CB('Check 2')],
               ]
layout = [
          [sg.Frame('My Frame Title', frame_layout, font='Any 12', title_color='blue')],
          [sg.Submit(), sg.Cancel()]
         ]

window = sg.Window('Frame with buttons', layout, font=("Helvetica", 12))
```
