So I've recently wanted to add the following feature to my programs:
1. When you minimise the program, it hides the window completely.
2. When you try to reopen the program, it checks to see if the program is already running, and if it is, it just shows that window again then exits the second program.
So I’ve recently wanted to add the following feature to my programs:

Catch the frame’s EVT_ICONIZE event and call Hide there if evt.IsIconized() is True
When you try to reopen the program, it checks to see if the program
is already running, and if it is, it just shows that window again then
exits the second program.
You can use wx.SingleInstanceChecker to see if there is already an instance of the application running. It doesn’t support doing anything with that other instance however, so you’ll need to come up with your own way to communicate with that instance and tell it to show itself again.

Thanks for that. I was aware of the instance checker.
Would it be horribly hackish just to have it do something like:
In the hidden window:
have a timer that runs every 5 seconds.
In timer, it opens appdata/roming/program name/randomfile.txt and
if value is 1, it shows itself?
Is that a bad idea?
thanks

I’m not sure of I would
use your way. I would be looking for code that works at the OS
level.
I would use the wx.SingleInstanceChecker to confirm the presents
of the first instance and then run code to open the minimized
window (most likely via the OS and platform depended and it
assumes it is minimized) - then close the second instance. I
would check the actual code (the c code) and determine how they
are finding the first instance - it might help you find the code
to open the first instance.
