## The One-Line GUI
|
||||
|
||||
For those of you into super-compact code, a complete customized GUI can be specified, shown, and received the results using a single line of Python code. The way this is done is to combine the call to `FlexForm` and the call to `LayoutAndRead`. `FlexForm` returns a `FlexForm` object which has the `LayoutAndRead` method.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
Instead of
|
||||
|
||||
import PySimpleGUI as sg
|
||||
|
||||
layout = [[sg.Text('Filename')],
|
||||
[sg.Input(), sg.FileBrowse()],
|
||||
[sg.OK(), sg.Cancel()] ]
|
||||
|
||||
button, (number,) = sg.FlexForm('Get filename example').LayoutAndRead(layout)
|
||||
|
||||
you can write this line of code for the exact same result (OK, two lines with the import):
|
||||
|
||||
import PySimpleGUI as sg
|
||||
|
||||
button, (filename,) = sg.FlexForm('Get filename example'). LayoutAndRead([[sg.Text('Filename')], [sg.Input(), sg.FileBrowse()], [sg.OK(), sg.Cancel()] ])
|
||||
--------------------
|
||||
## Multiple Columns
|
||||
Starting in version 2.9 (not yet released but you can get from current GitHub) you can use the Column Element. A Column is required when you have a tall element to the left of smaller elements.
|
||||
|
||||
This example uses a Column. There is a Listbox on the left that is 3 rows high. To the right of it are 3 single rows of text and input. These 3 rows are in a Column Element.
|
||||
|
||||
To make it easier to see the Column in the window, the Column background has been shaded blue. The code is wordier than normal due to the blue shading. Each element in the column needs to have the color set to match blue background.

## The 5-line GUI
|
||||
|
||||
Not all GUIs take 5 minutes. Some take 5 lines of code. This is a GUI with a custom layout contained in 5 lines of code.
|
||||
|
||||
import PySimpleGUI as sg
|
||||
|
||||
form = sg.FlexForm('My first GUI')
|
||||
|
||||
layout = [ [sg.Text('Enter your name'), sg.InputText()],
|
||||
[sg.OK()] ]
|
||||

button, (name,) = form.LayoutAndRead(layout)

||||
|
||||
## Making Your Custom GUI
|
||||
|
||||
That 5-minute estimate wasn't the time it takes to copy and paste the code from the Cookbook. You should be able to modify the code within 5 minutes in order to get to your layout, assuming you've got a straightforward layout.
