Demo - Running 2 windows with both being active at the same time
|
|
Three important things to note about this design patter:
|
|
1. The layout for window 2 is inside of the while loop, just before the call to window2=sg.Window
|
|
2. The read calls have timeout values of 100 and 0. You can change the 100 to whatever interval you wish
|
|
but must keep the second window's timeout at 0
|
|
3. There is a safeguard to stop from launching multiple copies of window2. Only 1 window2 is visible at a time
