I would like to know how to get a value (Text Input Box) using it's key but I don't really know how.
I think you can use values['key_name_here'] but I am not sure. I have tried that but it didn't seem to work. (At least I tried it on a text label)
I also need to get the text from a label but so far I can't see how to do that.
If you go back to the basic introduction to PySimpleGUI (Jumpstart), this tells you how to get the Text Input Box value.
import PySimpleGUI as sg
sg.theme('DarkAmber') # Add a touch of color
# All the stuff inside your window.
layout = [ [sg.Text('Some text on Row 1')],
[sg.Text('Enter something on Row 2'), sg.InputText()],
[sg.Button('Ok'), sg.Button('Cancel')] ]
# Create the Window
window = sg.Window('Window Title', layout)
# Event Loop to process "events" and get the "values" of the inputs
while True:
event, values = window.read()
if event == sg.WIN_CLOSED or event == 'Cancel': # if user closes window or clicks cancel
break
print('You entered ', values[0])
window.close()
You can see from the initialisation the line window = sg.Window('Window Title', layout) passes a list (layout) to the variable "window".
In the event loop, the state of Text Input Box is handled by event, values = window.read(), passing the text to "values". Values is a list, not a dictionary, which is why you don't access it by values['Inp1']; you access it by the list index values[0] (presumably if there was more than one InputBox, the next one would be values[1]).
Alternately, once the event loop is started, you can get the InputBox value directly using .get(): print(f'Label 1 is {layout[1][1].get()}')
Getting the text of a label is a bit obscure. The answer is to use .DisplayText: print(f'Label 1 is {layout[0][0].DisplayText}')
An example using direct access:
import PySimpleGUI as sg
sg.theme('DarkAmber') # Add a touch of color
# All the stuff inside your window.
layout = [ [sg.Text('Some text on Row 1')],
[sg.Text('Enter something on Row 2'), sg.InputText()],
[sg.Button('Ok'), sg.Button('Cancel')] ]
# Create the Window
window = sg.Window('Window Title', layout)
# Event Loop to process "events" and get the "values" of the inputs
while True:
event, values = window.read()
if event == sg.WIN_CLOSED or event == 'Cancel': # if user closes window or clicks cancel
break
print('You entered ', values[0])
# This is a directly accessed Label
print(f'Label 1 is {layout[0][0].DisplayText}')
# This is directly accessed InputBox
print(f'Label 1 is {layout[1][1].get()}')
# Note that layout is a list of lists
window.close()
There are different ways in Python to build dynamic strings. One of the latest, and my personal choice usually, is f-strings (Formatted String Literals). These are marked by putting an 'f' in front of the string f'Label 1 is {layout[1][1].get()}'.
The order of widgets is defined by the layout. Each row is a list of widgets, and then all the lists are added to the layout container. This means the first row of widgets is layout[0]. The first widget on the first row is layout[0][0].
