When a menu item has a key and it is chosen, then entire string is returned. If Hide were selected, then Hide::key would be returned from the Read. Note that the shortcut character & is NOT returned from Reads.
## Dynamic Windows (Element Visibility)
Finally, the ability to grow and shrink has been added as of release 0.20.0
While the window **appears** to be dynamic, the reality is that the elements are created up front, when you define the window layout. You will create these "extra" elements with the flag `visible=False`. Then, when you wish to show those elements, call the element's `Update` method setting `visible=True`.
After you call the `Update` method, it's important to call `window.VisibilityChanged()` so that your window can change sizes. Without that call your window will not shrink. It will grow properly, but it will not shrink. While this could have been done by PySimpleGUI on the user's behalf, the thought was that perhaps the user wants the window size to remain the same and the element simply appears and disappears, leaving a blank spot. If the window automatically grew and shrank, this would not be possible. Just buck-up and make the call to `VisibilityChanged`.
## `enable_events` Parameter
All elements that are capable of producing events now have a parameter `enable_events`. This is *identical* to the old parameter `change_submits` or `click_submits`. The idea is to standardize on 1 name that all elements use. The old parameters will continue to work, but the documentation and sample programs will steer you away from them and towards enable_events.

#### Note regarding Python versions
As of 9/25/2018 **both Python 3 and Python 2.7 are supported**! The Python 3 version is named `PySimpleGUI`. The Python 2.7 version is `PySimpleGUI27`. They are installed separately and the imports are different. See instructions in Installation section for more info.
#### Qt Version
# Qt Version
Check out the new PySimpleGUI port to the Qt GUI Framework. You can learn more on the [PySimpleGUIQt GitHub site](https://github.com/MikeTheWatchGuy/PySimpleGUI/tree/master/PySimpleGUIQt). There is a separate Readme file for the Qt version that you'll find there. Give it a shot if you're looking for something a bit more "modern". PySimpleGUIQt is currently in Alpha. All of the widgets are operational and your source code is completely portable from one platform to another by simply changing the import statement.

Are there enough things on there to cover your GUI solution?
### Source code compatibility
Your source code is completely portable from one platform to another by simply changing the import statement.
### Platforms
It's surprising that Python GUI code is completely cross platform from Windows to Mac to Linux. No source code changes. This is true for both PySimpleGUI and PySimpleGUIQt.
However, Macs suck. They suck on tkinter in particular. I had to completely turn off the "Look and feel" calls for Macs. Colored buttons in particular are broken. Not in the PySimpleGUI code, of course. It's mostly because Macs suck. Consider using Qt instead of tkinter on the Mac. Or, if using tkinter, bring your own button images.

### Window Location
PySimpleGUI computes the exact center of your window and centers the window on the screen. If you want to locate your window elsewhere, such as the system default of (0,0), if you have 2 ways of doing this. The first is when the window is created. Use the `location` parameter to set where the window. The second way of doing this is to use the `SetOptions` call which will set the default window location for all windows in the future.
### Sizes
### Window Size
You can get your window's size by access the `Size`property. The window has to be Read once or Finalized in order for the value to be correct. Note that it's a property, not a call.
`my_windows_size = window.Size`
To finalize your window:
```pytyhon
window = Window('My Title').Layout(layout).Finalize()
```
### Element Sizes
Note several variables that deal with "size". Element sizes are measured in characters. A Text Element with a size of 20,1 has a size of 20 characters wide by 1 character tall.
The default Element size for PySimpleGUI is `(45,1)`.
@ -1638,6 +1679,15 @@ Then to get the input value from the read it would be:

You also use the same key if you want to call Update on an element. Please see the section below on Updates to understand that usage.
#### Visible
Beginning in version 3.17 you can create Elements that are initially invisible that you can later make visible.
To create an invisible Element, place the element in the layout like you normally would and add the parameter `visible=False`.
Later when you want to make that Element visible you simply call the Element's `Update` method and pass in the parameter `visible=True`
This feature works best on Qt, but does work on the tkinter version as well. The visible parameter can also be used with the Column and Frame "container" Elements.

## Shortcut Functions / Multiple Function Names
Many of the main method calls and Element names have shortcuts. This enables you to code much quicker once you are used to using the SDK. The Text Element, for example, has 3 different names `Text`, `Txt` or`T`. InputText can also be written `Input` or `In` . `FindElement` was recently renamed to `Element` because it's a commonly used function.

**auto_size_text**
### `auto_size_text `
A `True` value for `auto_size_text`, when placed on Text Elements, indicates that the width of the Element should be shrunk do the width of the text. The default setting is True.
**Shortcut functions**

There is an important difference between Qt and tkinter sliders. On Qt, the slider values must be integer, not float. If you want your slider to go from 0.1 to 1.0, then make your slider go from 1 to 10 and divide by 10. It's an easy math thing to do and not a big deal.

### Qt Differences - `values` is a range!
Note that Qt does not allow arbitrary spinner values. With PySimpleGUI-tkinter you can have any values in your list. In Qt they must be integers. Yea, it kinda sucks. I'm working on it.
On Qt values is a tuple representing a range. On plain PySimpleGUI this value is a list of items. Make sure on the plain version you specify items as a list using [] and not a generator using ().

## Image Element
Images can be placed in your window provide they are in PNG, GIF, PPM/PGM format. JPGs cannot be shown because tkinter does not naively support JPGs. You can use the Python Imaging Library (PIL) package to convert your image to PNG prior to calling PySimpleGUI if your images are in JPG format.

All input Elements create an entry in the list of return values. A Text Input Element creates a string in the list of items returned.

There are two methods that can be called:
InputText.Update(new_Value) - sets the input value
Input.Text(Get() - returns the current value of the field.
Input.Update(new_Value) - sets the input to new_value
Input.Get() - returns the current value of the field.
Shorthand functions that are equivalent to `InputText` are `Input` and `In`
#### `do_not_clear` Parameter
**Important** - This trips a lot of people up. If you do not set the `do_not_clear` parameter then the input field will clear when an event takes place. The behavior is a "forms" style window development. The assumption is that you want the field to clear. If you are writing a chat program then you're thankful. The rest of you, I'm sorry.

### Qt Sliders
There is an important difference between Qt and tkinter sliders. On Qt, the slider values must be integer, not float. If you want your slider to go from 0.1 to 1.0, then make your slider go from 1 to 10 and divide by 10. It's an easy math thing to do and not a big deal. Just deal with it.... you're writing software after all. Presumably you know how to do these things. ;-)

### Qt Differences - `values` is a range!
Note that Qt does not allow arbitrary spinner values. With PySimpleGUI-tkinter you can have any values in your list. In Qt they must be integers. Yea, it kinda sucks. I'm working on it.
On Qt values is a tuple representing a range. On plain PySimpleGUI this value is a list of items. Make sure on the plain version you specify items as a list using [] and not a generator using ().

## Image Element
Images can be placed in your window provide they are in PNG, GIF, PPM/PGM format. JPGs cannot be shown because tkinter does not naively support JPGs. You can use the Python Imaging Library (PIL) package to convert your image to PNG prior to calling PySimpleGUI if your images are in JPG format.
Image(filename=None,
data=None,
background_color=None,
size=(None, None),

Parameter definitions
filename - file name if the image is in a file
data - if image is in RAM (PIL format?)
data_base64 - image in base64 format
background_color - Color of background
size - Size (Width, Height) of image in pixels
pad - Padding around Element in the window
key - Key used to find the element
tooltip - text to show when mouse if hovered over image
click_submits, enable_events - if True returns event when image is clicked
visible - if False will create image as hidden
size_px - size of image in pixels
