## One Element Updating Another
You can easily build "compound elements" in a single like of code. This recipe shows you how to add a numeric value onto a slider.
```python
import PySimpleGUI as sg
layout = [[sg.Text('Slider Demonstration'), sg.Text('', key='_OUTPUT_')],
[sg.T('0',key='_LEFT_'),
sg.Slider((1,100), key='_SLIDER_', orientation='h', enable_events=True, disable_number_display=True),
sg.T('0', key='_RIGHT_')],
[sg.Button('Show'), sg.Button('Exit')]]
window = sg.Window('Window Title').Layout(layout)
while True: # Event Loop
event, values = window.Read()
print(event, values)
if event is None or event == 'Exit':
break
window.Element('_LEFT_').Update(values['_SLIDER_'])
window.Element('_RIGHT_').Update(values['_SLIDER_'])
window.Close()
```
## Multiple Windows
This recipe is a design pattern for multiple windows where the first window is not active while the second window is showing. The first window is hidden to discourage continued interaction.
```Python
"""
PySimpleGUI The Complete Course Lesson 7 - Multiple Windows"""
import PySimpleGUI as sg
# Design pattern 1 - First window does not remain active
layout = [[ sg.Text('Window 1'),],
[sg.Input(do_not_clear=True)],
[sg.Text('', key='_OUTPUT_')],
[sg.Button('Launch 2')]]
win1 = sg.Window('Window 1').Layout(layout)
win2_active=False
while True:
ev1, vals1 = win1.Read(timeout=100)
if ev1 is None:
break
win1.FindElement('_OUTPUT_').Update(vals1[0])
if ev1 == 'Launch 2' and not win2_active:
win2_active = True
win1.Hide()
layout2 = [[sg.Text('Window 2')], # note must create a layout from scratch every time. No reuse
[sg.Button('Exit')]]
win2 = sg.Window('Window 2').Layout(layout2)
while True:
ev2, vals2 = win2.Read()
if ev2 is None or ev2 == 'Exit':
win2.Close()
win2_active = False
win1.UnHide()
break
